電源饋送控制元件Power feed control element

本發明是關於一種電源饋送控制元件。The present invention relates to a power feed control element.

習知提出一種電源饋送控制元件，所述電源饋送控制元件控制自外部電源至電動車輛之電源饋送。電源饋送控制元件包含連接至外部電源(諸如，商用AC電源)之電源側插頭，以及連接至電動車輛之車輛側插頭，電源側插頭經由電纜而連接至車輛側插頭(參見(例如)日本專利申請公開案第2009-240053號)。Conventionally, a power feed control element is proposed that controls the power feed from an external power source to an electric vehicle. The power feeding control element includes a power side plug connected to an external power source such as a commercial AC power source, and a vehicle side plug connected to the electric vehicle, and the power side plug is connected to the vehicle side plug via a cable (see, for example, Japanese Patent Application) Publication No. 2009-240053).

為了克服以下狀況：當為電動車輛之電池組充電時，電源饋送控制元件之高壓側短路至車輛主體，故電源饋送控制元件包含：安置於電源供應路徑中之繼電器，其用於在兩個插頭之間電連接；以及漏電偵測電路，其用於偵測是否發生漏電。當漏電偵測電路偵測到漏電時，開啟繼電器以藉此切斷至電動車輛之電源供應。In order to overcome the situation that when charging the battery pack of the electric vehicle, the high voltage side of the power feed control element is short-circuited to the vehicle body, so the power feed control element comprises: a relay disposed in the power supply path for the two plugs An electrical connection; and a leakage detecting circuit for detecting whether a leakage has occurred. When the leakage detecting circuit detects a leakage, the relay is turned on to cut off the power supply to the electric vehicle.

在習知電源饋送控制元件中，為了在發生漏電時可靠地切斷至電動車輛之電源供應，無論何時向電動車輛供應電源，均檢查漏電偵測電路。具體言之，當電源饋送控制元件連接至電動車輛且接收來自電動車輛之充電啟用信號時，電源饋送控制元件關閉繼電器且模擬虛擬漏電以檢查漏電偵測電路是否正常操作。In the conventional power feeding control element, in order to reliably cut off the power supply to the electric vehicle when a leakage occurs, the leakage detecting circuit is checked whenever power is supplied to the electric vehicle. In particular, when the power feed control element is coupled to the electric vehicle and receives a charge enable signal from the electric vehicle, the power feed control element turns off the relay and simulates a virtual leak to check if the leak detection circuit is operating normally.

當偵測到漏電時，漏電偵測電路開啟繼電器且接著檢查繼電器是否熔融結合(fusion-bonded)。本文中，當發現漏 電偵測正常執行且繼電器無熔融結合時，電源饋送控制元件開始藉由關閉繼電器而將電源饋送至電動車輛。When a leak is detected, the leakage detection circuit turns on the relay and then checks if the relay is fusion-bonded. In this article, when a leak is found When the electrical detection is normally performed and the relay is not melted, the power feed control element begins to feed power to the electric vehicle by turning off the relay.

因此，當為電動車輛充電一次時，兩次開啟及關閉併入於電源饋送控制元件中之繼電器。隨著開啟及關閉繼電器之次數增加，電源饋送控制元件之壽命縮短，此為不樂見的情形。Therefore, when charging the electric vehicle once, the relay incorporated in the power feeding control element is turned on and off twice. As the number of times the relay is turned on and off increases, the life of the power feed control element is shortened, which is an unpleasant situation.

電源饋送控制元件1包含繼電器RY1、控制部分20、電源供應偵測部分21、漏電偵測部分22、L側電壓偵測器23、N側電壓偵測器24、繼電器驅動單元25、信號輸入部分26、信號輸出部分27，以及漏電產生部分28。The power feeding control element 1 includes a relay RY1, a control portion 20, a power supply detecting portion 21, a leakage detecting portion 22, an L-side voltage detector 23, an N-side voltage detector 24, a relay driving unit 25, and a signal input portion. 26. A signal output portion 27 and a leakage generating portion 28.

繼電器RY1通常具有分別***至電壓側線路L1以及接地側線路L2中之開啟接點，且接通及斷開自電源側插頭P1至車輛側插頭P2之電源供應。The relay RY1 generally has an open contact inserted into the voltage side line L1 and the ground side line L2, respectively, and turns on and off the power supply from the power source side plug P1 to the vehicle side plug P2.

控制部分20包含積體電路(IC)以藉此控制整個電源饋送控制元件1。The control section 20 includes an integrated circuit (IC) to thereby control the entire power feed control element 1.

電源供應偵測部分21***於繼電器RY1與電源側插頭P1之間，且偵測產生於電源側線路L1與接地側線路L2之間的電壓之零交叉(zero cross)以檢查電源是否自商用AC電源供應。The power supply detecting portion 21 is inserted between the relay RY1 and the power source side plug P1, and detects a zero cross of the voltage generated between the power source side line L1 and the ground side line L2 to check whether the power source is self-commercial AC. power supply.

漏電偵測部分22基於零相電流互感器22a之輸出而偵測至電動車輛100(包含電動車輛100側之電路)之電源供應路徑中的漏電，電源側線路L1以及接地側線路L2通過零相電流互感器22a之核心。當歸因於漏電而在流經電源側線路L1與接地側線路L2之電流之間發生不平衡時，對應於不平衡電流之電流在零相電流互感器22a之二次側中流動。The leakage detecting portion 22 detects the leakage in the power supply path to the electric vehicle 100 (the circuit including the electric vehicle 100 side) based on the output of the zero-phase current transformer 22a, and the power supply side line L1 and the ground side line L2 pass the zero phase The core of the current transformer 22a. When an imbalance occurs between the current flowing through the power source side line L1 and the ground side line L2 due to the leakage, the current corresponding to the unbalanced current flows in the secondary side of the zero phase current transformer 22a.

因此，漏電偵測部分22基於零相電流互感器22a之二次側之輸出而偵測漏電。當偵測到漏電時，漏電偵測部分22將漏電偵測信號輸出至控制部分20之輸入端子PI1且使得繼電器RY1開啟。Therefore, the leakage detecting portion 22 detects the leakage based on the output of the secondary side of the zero-phase current transformer 22a. When the leakage is detected, the leakage detecting portion 22 outputs the leakage detecting signal to the input terminal PI1 of the control portion 20 and causes the relay RY1 to be turned on.

L側電壓偵測器23偵測產生於介於繼電器RY1與車輛側插頭P2(亦即，繼電器RY1之二次側)之間的電源側線路L1上的電壓。The L-side voltage detector 23 detects a voltage generated on the power source side line L1 between the relay RY1 and the vehicle side plug P2 (that is, the secondary side of the relay RY1).

N側電壓偵測器24偵測產生於介於繼電器RY1與車輛側插頭P2(亦即，繼電器RY1之二次側)之間的接地側線路L2上的電壓。The N-side voltage detector 24 detects a voltage generated on the ground-side line L2 between the relay RY1 and the vehicle-side plug P2 (that is, the secondary side of the relay RY1).

繼電器驅動單元25回應於自控制部分20輸入之控制信號以及來自漏電偵測部分22之信號而開啟或關閉繼電器RY1。The relay driving unit 25 turns on or off the relay RY1 in response to a control signal input from the control portion 20 and a signal from the leakage detecting portion 22.

信號輸入部分26經由導電線路L1至L3分別提供之導電線路L4(在下文中，稱作“信號線路”)而連接至電動車輛100。信號輸入部分26接收所謂的CPLT信號(控制引導信號(control pilot signal))，且將CPLT信號輸出至 控制部分20之輸入端子PI5，CPLT信號包含操作狀態通知。The signal input portion 26 is connected to the electric vehicle 100 via a conductive line L4 (hereinafter, referred to as a "signal line") respectively provided by the conductive lines L1 to L3. The signal input portion 26 receives a so-called CPLT signal (control pilot signal) and outputs the CPLT signal to The input terminal PI5 of the control section 20, the CPLT signal contains an operation status notification.

信號輸出部分27將CPLT信號輸出至電動車輛100側，所述CPLT信號之信號位準以及波形是基於自控制部分20之輸出端子PO2輸出之信號而修改。The signal output portion 27 outputs the CPLT signal to the electric vehicle 100 side, and the signal level and waveform of the CPLT signal are modified based on the signal output from the output terminal PO2 of the control portion 20.

當控制部分20之輸出端子PO3處之電壓變為L位準時，漏電產生部分28藉由在電源側線路L1與接地側線路L2之間短路而模擬虛擬漏電。另外，漏電產生部分28具備測試信號產生電路28a，其用於在按壓漏電測試按鈕B1時產生測試信號。當漏電產生部分28中之測試信號產生電路28a產生測試信號時，如上文所提及，電源側線路L1短路至接地側線路L2，藉此產生虛擬漏電。When the voltage at the output terminal PO3 of the control portion 20 becomes the L level, the leakage generating portion 28 simulates virtual leakage by short-circuiting between the power supply side line L1 and the ground side line L2. Further, the leakage generating portion 28 is provided with a test signal generating circuit 28a for generating a test signal when the leakage test button B1 is pressed. When the test signal generating circuit 28a in the leakage generating portion 28 generates the test signal, as mentioned above, the power source side line L1 is short-circuited to the ground side line L2, thereby generating virtual leakage.

另外，電源饋送控制元件1具有待連接至繼電器RY1之電源側處的電源側線路L1、接地側線路L2以及接地線路L3之組件20至28，藉此將操作電源供應至組件20至28中之每一者。In addition, the power feeding control element 1 has components 20 to 28 to be connected to the power source side line L1, the ground side line L2, and the ground line L3 at the power source side of the relay RY1, thereby supplying the operating power to the components 20 to 28 Each.

本文中，藉由改變(例如)電動車輛100側之電路中的分壓比而以電壓位準來改變CPLT信號(亦即，狀態通知信號)，且根據控制部分20之指令(例如，給定電壓信號或工作週期信號(duty signal))自信號輸出部分27輸出CPLT信號。下文所描述之表1展示CPLT信號之實例。當CPLT信號具有電壓位準+12V(狀態A)時，表示無電動車輛100連接至車輛側插頭P2(等待車輛連接)。另外，當CPLT信號具有電壓位準(+9V)(狀態B)時，表示車 輛側插頭P2連接至電動車輛100且至電動車輛100之電路之連接得到確認(檢查車輛連接)。Herein, the CPLT signal (ie, the state notification signal) is changed at a voltage level by changing, for example, a voltage division ratio in a circuit on the side of the electric vehicle 100, and according to an instruction of the control portion 20 (for example, given A voltage signal or a duty signal outputs a CPLT signal from the signal output portion 27. Table 1 described below shows an example of a CPLT signal. When the CPLT signal has a voltage level of +12 V (state A), it indicates that the electric-less vehicle 100 is connected to the vehicle-side plug P2 (waiting for the vehicle connection). In addition, when the CPLT signal has a voltage level (+9V) (state B), it means the car The side plug P2 of the vehicle is connected to the electric vehicle 100 and the connection to the electric circuit of the electric vehicle 100 is confirmed (checking the vehicle connection).

此外，當CPLT信號為具有在(+9V)與(-12V)之間交替之電壓位準(狀態C)的工作週期信號時，表示至電動車輛100之連接完成且等待來自電動車輛100側之充電致能信號。再另外，當CPLT信號為具有在(+6V)與(-12V)之間交替之電壓位準(狀態D)的工作週期信號時，表示自電動車輛100側輸入充電致能信號。Further, when the CPLT signal is a duty cycle signal having a voltage level (state C) alternating between (+9V) and (-12V), it indicates that the connection to the electric vehicle 100 is completed and waiting for the electric vehicle 100 side. Charging enable signal. Still further, when the CPLT signal is a duty cycle signal having a voltage level (state D) alternating between (+6V) and (-12V), it indicates that the charge enable signal is input from the electric vehicle 100 side.

圖2展示L側電壓偵測器23以及N側電壓偵測器24之具體電路圖。L側電壓偵測器23包含：連接於電源側線路L1與接地線路L3之間的電容器C1、電阻R1以及電容器C2之串聯電路；並聯連接至電容器C2之電阻R2；連接至電容器C2之兩端之電容器C3，其中二極體D1***於電容器C2與電容器C3之間；齊納二極體ZD1以及電阻R5，齊納二極體ZD1以及電阻R5中之每一者並聯連接至電容器C3；以及比較器CP1。FIG. 2 shows a specific circuit diagram of the L-side voltage detector 23 and the N-side voltage detector 24. The L-side voltage detector 23 includes: a series circuit of a capacitor C1, a resistor R1, and a capacitor C2 connected between the power source side line L1 and the ground line L3; a resistor R2 connected in parallel to the capacitor C2; and a terminal connected to the capacitor C2 a capacitor C3, wherein the diode D1 is inserted between the capacitor C2 and the capacitor C3; the Zener diode ZD1 and the resistor R5, the Zener diode ZD1 and the resistor R5 are each connected in parallel to the capacitor C3; Comparator CP1.

比較器CP1比較電容器C3上之電壓與參考電壓，所述參考電壓是藉由將自電源供應之預定電壓除以電阻R3 與R4之比例而獲得，藉此偵測無電源供應至電源側線路L1。比較器CP1之輸出輸入至控制部分20之輸入端子PI3。本實施例中，在電源側插頭P1連接至電源插座且繼電器RY1關閉之狀態下，在電源側線路L1處於正極性之半週期期間，經由二極體D1對電容器C3充電。The comparator CP1 compares the voltage on the capacitor C3 with a reference voltage by dividing the predetermined voltage from the power supply by the resistor R3. Obtained in proportion to R4, thereby detecting no power supply to the power supply side line L1. The output of the comparator CP1 is input to the input terminal PI3 of the control section 20. In the present embodiment, in a state where the power supply side plug P1 is connected to the power outlet and the relay RY1 is turned off, the capacitor C3 is charged via the diode D1 while the power supply side line L1 is in the positive half cycle.

此時，電容器C3上之電壓超過參考電壓且將比較器CP1之輸出自L位準反向成H位準。應注意，在電源側線路L1處於負極性之另一半週期期間，經由電阻R5使儲存於電容器C3中之電荷放電，以使得電容器C3上之電壓逐漸降低。電容器C3以及電阻R5較佳為經設計而具有時間常數，以使得在電源側線路L1之負半週期期間，電容器C3上之電壓不會降低至低於參考電壓。At this time, the voltage on the capacitor C3 exceeds the reference voltage and the output of the comparator CP1 is inverted from the L level to the H level. It should be noted that during the other half cycle in which the power supply side line L1 is in the negative polarity, the electric charge stored in the capacitor C3 is discharged via the resistor R5, so that the voltage on the capacitor C3 is gradually lowered. Capacitor C3 and resistor R5 are preferably designed to have a time constant such that during the negative half cycle of supply side line L1, the voltage across capacitor C3 does not decrease below the reference voltage.

類似於L側電壓偵測器23，N側電壓偵測器24包含：連接於接地側線路L2與接地線路L3之間的電容器C11、電阻R11以及電容器C12之串聯電路；並聯連接至電容器C12之電阻R12；連接至電容器C12之兩端之電容器C13，其中二極體D11***於電容器C12與電容器C13之間；齊納二極體ZD11以及電阻R15，齊納二極體ZD11以及電阻R15中之每一者並聯連接至電容器C13；以及比較器CP11。Similar to the L-side voltage detector 23, the N-side voltage detector 24 includes a series circuit of a capacitor C11, a resistor R11, and a capacitor C12 connected between the ground-side line L2 and the ground line L3; and is connected in parallel to the capacitor C12. a resistor R12; a capacitor C13 connected to both ends of the capacitor C12, wherein the diode D11 is inserted between the capacitor C12 and the capacitor C13; the Zener diode ZD11 and the resistor R15, the Zener diode ZD11 and the resistor R15 Each is connected in parallel to capacitor C13; and comparator CP11.

比較器CP11比較電容器C13上之電壓與參考電壓，所述參考電壓是藉由將來自電源之預定電壓除以電阻R13與R14之比率而獲得，藉此偵測無電源供應至接地側線路L2。比較器CP11之輸出輸入至控制部分20之輸入端子PI4。本文中，在電源側插頭P1連接至電源插座且繼電器 RY1關閉之狀態下，在接地側線路L2處於正極性之半週期期間，經由二極體D11對電容器C13充電。The comparator CP11 compares the voltage on the capacitor C13 with a reference voltage obtained by dividing the predetermined voltage from the power supply by the ratio of the resistors R13 and R14, thereby detecting no power supply to the ground side line L2. The output of the comparator CP11 is input to the input terminal PI4 of the control section 20. In this paper, the power supply side plug P1 is connected to the power outlet and the relay In a state where RY1 is off, the capacitor C13 is charged via the diode D11 while the ground-side line L2 is in the positive half cycle.

此時，電容器C13上之電壓超過由電阻R13、R14分壓參考電壓所得之電壓，且將比較器CP11之輸出自L位準反向成H位準。應注意，在接地側線路L2處於負極性之另一半週期期間，經由電阻R15使儲存於電容器C13中之電荷放電，以使得電容器C13上之電壓逐漸降低。電容器C13以及電阻R15較佳經設計而具有時間常數，以使得在接地側線路L2之負半循環期間，電容器C13上之電壓不會降低至低於參考電壓。At this time, the voltage on the capacitor C13 exceeds the voltage obtained by dividing the reference voltage by the resistors R13, R14, and the output of the comparator CP11 is inverted from the L level to the H level. It should be noted that during the other half period in which the ground side line L2 is in the negative polarity, the electric charge stored in the capacitor C13 is discharged via the resistor R15, so that the voltage on the capacitor C13 is gradually lowered. Capacitor C13 and resistor R15 are preferably designed to have a time constant such that during the negative half cycle of ground side line L2, the voltage across capacitor C13 does not decrease below the reference voltage.

將描述在上述組態下的本發明實施例之電源饋送控制元件1之操作。The operation of the power feeding control element 1 of the embodiment of the present invention under the above configuration will be described.

首先，請參照圖4描述在開始充電之前的操作。當使用者將電源側插頭P1連接至電源插座時(S1)，電源供應控制元件1自商用AC電源得到電源且開始操作。在無車輛側插頭P2連接至電動車輛100之狀態下，自信號輸出部分27輸出之CPLT信號具有+12V之值(狀態A)，且CPLT信號輸入至信號輸入部分26(S2)。控制部分20基於自信號輸入部分26輸入之CPLT信號而判定無車輛側插頭P2連接至電動車輛100。應注意，在此狀態下，繼電器RY1處於斷開狀態。First, the operation before starting charging will be described with reference to FIG. When the user connects the power source side plug P1 to the power outlet (S1), the power supply control element 1 receives power from the commercial AC power source and starts operating. In a state where the vehicle-less side plug P2 is connected to the electric vehicle 100, the CPLT signal output from the signal output portion 27 has a value of +12 V (state A), and the CPLT signal is input to the signal input portion 26 (S2). The control section 20 determines that the vehicle-less side plug P2 is connected to the electric vehicle 100 based on the CPLT signal input from the signal input section 26. It should be noted that in this state, the relay RY1 is in the off state.

其次，當使用者將車輛側插頭P2連接至電動車輛100之插座101時(S3)，由車輛側之電路將CPLT信號之電壓位準改變至+9V(狀態B)，且經由信號輸入部分26將CPLT 信號輸入至控制部分20。Next, when the user connects the vehicle side plug P2 to the outlet 101 of the electric vehicle 100 (S3), the voltage level of the CPLT signal is changed to +9 V (state B) by the circuit on the vehicle side, and via the signal input portion 26 Will CPLT The signal is input to the control section 20.

當CPLT信號轉變成狀態B時(S4中之"是")，控制部分20判定車輛側插頭P2已連接至電動車輛100。接著，控制部分20移動至充電致能等待狀態且經由信號輸出部分27將CPLT信號改變成狀態C(S5)。當CPLT信號轉變成狀態C時，電動車輛100中之充電電路103判定電源饋送控制元件1處於充電致能等待狀態。因此，充電電路103接通充電致能開關。當充電致能開關在電動車輛100側處接通時(S6)，由電動車輛100側之電路將CPLT信號之電壓位準改變至+6V，且將用於告知充電致能之CPLT信號輸出至電源饋送控制元件1之控制部分20。When the CPLT signal is converted to the state B (YES in S4), the control section 20 determines that the vehicle side plug P2 is connected to the electric vehicle 100. Next, the control section 20 moves to the charge enable wait state and changes the CPLT signal to the state C via the signal output section 27 (S5). When the CPLT signal is turned into the state C, the charging circuit 103 in the electric vehicle 100 determines that the power feeding control element 1 is in the charge enable waiting state. Therefore, the charging circuit 103 turns on the charge enable switch. When the charge enable switch is turned on at the side of the electric vehicle 100 (S6), the voltage level of the CPLT signal is changed to +6 V by the circuit on the side of the electric vehicle 100, and the CPLT signal for notifying the charge enable is output to The power supply feeds the control portion 20 of the control element 1.

當CPLT信號之電壓位準改變至+6V時(S7中之"是")，控制部分20判定充電已被電動車輛100致能且經由信號輸出部分27將CPLT信號改變至狀態D(S8)。另外，控制部分20控制繼電器驅動單元25以接通繼電器RY1(S9)。因此，將電源供應至電動車輛100，藉此開始充電(S10)。When the voltage level of the CPLT signal is changed to +6 V (YES in S7), the control section 20 determines that charging has been enabled by the electric vehicle 100 and changes the CPLT signal to the state D via the signal output portion 27 (S8). In addition, the control section 20 controls the relay drive unit 25 to turn on the relay RY1 (S9). Therefore, power is supplied to the electric vehicle 100, thereby starting charging (S10).

接下來，請參照圖5A中之流程圖描述漏電偵測部分22之檢查操作，以及在停止至電動車輛100之電源供應時對繼電器中之熔融結合的偵測。Next, the inspection operation of the leakage detecting portion 22 and the detection of the fusion bonding in the relay when the power supply to the electric vehicle 100 is stopped will be described with reference to the flowchart in FIG. 5A.

在將電源自電源饋送控制元件1供應至電動車輛100之狀態下，CPLT信號具有在+6V與-12V之間交替之電壓位準(狀態D)(圖5A中之S11)。當電動車輛100中完成充電時(S12)，電動車輛100將CPLT信號之信號位準自 此狀態改變至+9V。電源饋送控制元件1之控制部分20恆定地監視經由信號輸入部分26輸入之CPLT信號，且當控制部分20偵測到CPLT信號之電壓位準改變至+9V時(S13之"是")，判定充電完成且停止電源供應。In a state where the power is supplied from the power feeding control element 1 to the electric vehicle 100, the CPLT signal has a voltage level (state D) alternating between +6 V and -12 V (S11 in Fig. 5A). When charging is completed in the electric vehicle 100 (S12), the electric vehicle 100 sets the signal level of the CPLT signal from This state changes to +9V. The control section 20 of the power feeding control element 1 constantly monitors the CPLT signal input via the signal input section 26, and when the control section 20 detects that the voltage level of the CPLT signal changes to +9 V ("Y" of S13), it is determined Charging is complete and the power supply is stopped.

亦即，控制部分20控制信號輸出部分27以將CPLT信號改變至狀態C(S14)，且，在此操作之後，控制漏電產生部分28以模擬虛擬漏電(S15)。此時，若漏電偵測部分22正常地操作，則偵測到漏電。因此，漏電偵測部分22使得繼電器RY1開啟且將漏電偵測信號輸出至控制部分20之輸入端子PI1。That is, the control section 20 controls the signal output section 27 to change the CPLT signal to the state C (S14), and after this operation, controls the leakage generating section 28 to simulate virtual leakage (S15). At this time, if the leakage detecting portion 22 operates normally, a leak is detected. Therefore, the leakage detecting portion 22 causes the relay RY1 to be turned on and outputs the leakage detecting signal to the input terminal PI1 of the control portion 20.

在由漏電產生部分28模擬虛擬漏電之後，控制部分20檢查漏電偵測信號是否輸入至控制部分20之輸入端子PI1。當無漏電偵測信號輸入至控制部分20之輸入端子PI1時，控制部分20判定漏電偵測部分22未能偵測到漏電(S16之"否")，且點亮錯誤指示燈LP2(S17)。在本發明實施例中，藉由點亮錯誤指示燈LP2而通知漏電偵測中之異常操作。然而，通知不限於此情形，亦可藉由聲音來通知，例如，藉由使用蜂鳴器來通知。After the virtual leakage is simulated by the leakage generating portion 28, the control portion 20 checks whether the leakage detecting signal is input to the input terminal PI1 of the control portion 20. When the no-leakage detection signal is input to the input terminal PI1 of the control portion 20, the control portion 20 determines that the leakage detecting portion 22 fails to detect the leakage ("NO" of S16), and illuminates the error indicator LP2 (S17) . In the embodiment of the present invention, the abnormal operation in the leakage detection is notified by lighting the error indicator LP2. However, the notification is not limited to this case, and may be notified by sound, for example, by using a buzzer.

另一方面，當漏電偵測信號輸入至控制部分20之輸入端子PI1時，控制部分20判定漏電偵測部分22偵測到漏電(S16之"是")，且移動至繼電器RY1中之熔融結合檢查。當漏電偵測部分22偵測到漏電時，控制部分20開啟繼電器RY1。若繼電器RY1熔融結合，則在繼電器RY1之二次側處的電源側線路L1之電壓與接地側線路L2之電 壓兩者皆變成零。On the other hand, when the leakage detecting signal is input to the input terminal PI1 of the control portion 20, the control portion 20 determines that the leakage detecting portion 22 detects the electric leakage ("YES" of S16), and moves to the fusion bonding in the relay RY1. an examination. When the leakage detecting portion 22 detects a leak, the control portion 20 turns on the relay RY1. If the relay RY1 is fusion-bonded, the voltage of the power source side line L1 and the ground side line L2 at the secondary side of the relay RY1 Both pressures become zero.

如上文所描述，L側電壓偵測器23以及N側電壓偵測器24偵測是否有超過各別預定臨限值之電壓產生於繼電器RY1之二次側之電源側線路L1以及接地側線路L2上。控制部分20基於電壓偵測器23與24兩者之偵測結果而檢查是否發生熔合結合(S18)。亦即，當超過預定臨限值之電壓產生於繼電器RY1之二次側上時，控制部分20判定繼電器RY1熔融結合，且藉由點亮錯誤指示燈LP2而告知繼電器RY1中發生熔融結合(S19)。As described above, the L-side voltage detector 23 and the N-side voltage detector 24 detect whether or not a voltage exceeding a predetermined threshold value is generated on the power supply side line L1 and the ground side line on the secondary side of the relay RY1. On L2. The control section 20 checks whether fusion bonding occurs based on the detection results of both of the voltage detectors 23 and 24 (S18). That is, when a voltage exceeding a predetermined threshold value is generated on the secondary side of the relay RY1, the control portion 20 determines that the relay RY1 is melt-bonded, and informs the relay RY1 that fusion bonding occurs by illuminating the error indicator lamp LP2 (S19). ).

另一方面，當繼電器RY1之二次側電壓低於預定臨限值時，控制部分20判定繼電器RY1未熔融結合(繼電器RY1開啟)，且錯誤指示燈LP2保持熄滅。本文中，熔融結合偵測部分包含L側電壓偵測器23、N側電壓偵測器24，以及控制部分20。資訊部分包含錯誤指示燈LP2。On the other hand, when the secondary side voltage of the relay RY1 is lower than the predetermined threshold value, the control portion 20 determines that the relay RY1 is not melt-bonded (the relay RY1 is turned on), and the error indicator lamp LP2 remains off. Herein, the fusion bonding detecting portion includes an L-side voltage detector 23, an N-side voltage detector 24, and a control portion 20. The information section contains the error indicator LP2.

另外，錯誤指示燈LP2可具有不同發光圖案，所述不同發光圖案區別熔融結合之偵測與漏電偵測之異常操作的偵測。因此，可藉由發光圖案之區別來通知各種種類之故障。另外，可藉由(例如)發出警報或蜂鳴器聲音來通知繼電器熔融結合之發生。在此狀況下，可發出蜂鳴器聲音以便在偵測熔融結合與偵測漏電偵測之異常操作之間具有不同音調。因此，可藉由作出音調之差異來通知各種種類之故障。In addition, the error indicator light LP2 may have different illumination patterns, which distinguish the detection of the abnormal operation of the fusion combined detection and the leakage detection. Therefore, various kinds of failures can be notified by the difference of the illuminating patterns. In addition, the occurrence of fusion bonding of the relay can be notified by, for example, issuing an alarm or a buzzer sound. In this case, a buzzer sound can be emitted to have a different tone between detecting the fusion bond and detecting the abnormal operation of the leak detection. Therefore, various kinds of failures can be notified by making a difference in pitch.

另外，電動車輛100(或電源饋送控制元件1)藉由使用聲音或光向使用者告知充電之完成。當向使用者告知 充電之完成且將車輛側插頭P2與插座101斷開時(S20)，CPLT信號改變至具有值+12V(狀態A)。當CPLT信號改變至具有值+12V時(S21中之"是")，控制部分20判定車輛側插頭P2與電動車輛100之插座101斷開，且返回至車輛連接等待狀態(S22)。In addition, the electric vehicle 100 (or the power feed control element 1) notifies the user of the completion of charging by using sound or light. When informed to the user When the charging is completed and the vehicle side plug P2 is disconnected from the outlet 101 (S20), the CPLT signal is changed to have a value of +12 V (state A). When the CPLT signal is changed to have a value of +12 V (YES in S21), the control portion 20 determines that the vehicle side plug P2 is disconnected from the outlet 101 of the electric vehicle 100, and returns to the vehicle connection waiting state (S22).

如上文所描述，控制部分20控制漏電產生部分28在停止至電動車輛100之電源供應時模擬虛擬漏電(自漏電)。當漏電偵測部分22偵測到漏電時，其使得繼電器RY1開啟。因此，在不增加開啟及關閉繼電器RY1之次數的情況下，可由漏電產生部分28以及漏電偵測部分22檢查漏電偵測操作，且可由L側電壓偵測器23以及N側電壓偵測器24檢查繼電器RY1之熔融結合。因此，可防止電源饋送控制元件1之壽命縮短。As described above, the control section 20 controls the leakage generating portion 28 to simulate virtual leakage (self-leakage) when stopping the power supply to the electric vehicle 100. When the leakage detecting portion 22 detects a leak, it causes the relay RY1 to be turned on. Therefore, the leakage detecting operation can be checked by the leakage generating portion 28 and the leakage detecting portion 22 without increasing the number of times the relay RY1 is turned on and off, and the L-side voltage detector 23 and the N-side voltage detector 24 can be used. Check the fusion bond of relay RY1. Therefore, the life of the power feed control element 1 can be prevented from being shortened.

在本發明實施例中，控制部分20控制漏電產生部分28在作為狀態通知信號之充電完成信號輸入至信號輸入部分26時模擬虛擬漏電，所述充電完成信號通知充電之完成。然而，不限於此情形，亦可在可判定至電動車輛之電源供應停止時模擬及偵測漏電。In the embodiment of the present invention, the control section 20 controls the leakage generating portion 28 to simulate virtual leakage when the charging completion signal as the state notification signal is input to the signal input portion 26, which is notified of completion of charging. However, it is not limited to this case, and it is also possible to simulate and detect leakage when it is determined that the power supply to the electric vehicle is stopped.

舉例而言，控制部分20可藉由偵測到無狀態通知信號輸入(由於車輛側插頭P2之斷開)而判定電源供應之停止。下文將參看圖5B描述此操作。For example, the control section 20 can determine the stop of the power supply by detecting the stateless notification signal input (due to the disconnection of the vehicle side plug P2). This operation will be described below with reference to FIG. 5B.

在將電源自電源饋送控制元件1供應至電動車輛100之狀態下，CPLT信號處於狀態D(圖5A中之S11)。在此狀態下，當車輛側插頭P2與電動車輛100之插座101 斷開時(S23)，CPLT信號改變至具有+12V之值(狀態A)(S24中之"是")。亦即，當無狀態通知信號輸入時，CPLT信號改變至狀態A。因此，當CPLT信號自狀態D改變至狀態A時，控制部分20判定無狀態通知信號自電動車輛100側輸入，亦即，車輛側插頭P2與電動車輛100之插座101斷開，且接著移動至停止至電動車輛100之電源供應之程序。In a state where the power is supplied from the power feeding control element 1 to the electric vehicle 100, the CPLT signal is in the state D (S11 in Fig. 5A). In this state, when the vehicle side plug P2 and the socket 101 of the electric vehicle 100 When disconnected (S23), the CPLT signal is changed to have a value of +12 V (state A) ("YES" in S24). That is, when the stateless notification signal is input, the CPLT signal changes to state A. Therefore, when the CPLT signal is changed from the state D to the state A, the control section 20 determines that the stateless notification signal is input from the electric vehicle 100 side, that is, the vehicle side plug P2 is disconnected from the outlet 101 of the electric vehicle 100, and then moves to The process of stopping the power supply to the electric vehicle 100 is stopped.

控制部分20控制漏電產生部分28模擬虛擬漏電(S25)。彼時，當發現漏電偵測部分22正常操作且偵測到漏電時，漏電偵測部分22開啟繼電器RY1且將漏電偵測信號輸出至控制部分20之輸入端子PI1。在由漏電產生部分28模擬虛擬漏電之後，控制部分20監視漏電偵測信號是否輸入至輸入端子PI1，且判定漏電偵測是否正常操作。The control section 20 controls the leakage generating portion 28 to simulate virtual leakage (S25). At that time, when the leakage detecting portion 22 is found to operate normally and the leakage is detected, the leakage detecting portion 22 turns on the relay RY1 and outputs the leakage detecting signal to the input terminal PI1 of the control portion 20. After the virtual leakage is simulated by the leakage generating portion 28, the control portion 20 monitors whether or not the leakage detecting signal is input to the input terminal PI1, and determines whether the leakage detecting is normally operated.

當無漏電偵測信號輸入至控制部分20之輸入端子PI1時，控制部分20判定漏電偵測部分22可能未偵測到漏電(S26之"否")，且點亮錯誤指示燈LP2。接著，向使用者告知漏電偵測操作之異常(S27)。When the no-leakage detection signal is input to the input terminal PI1 of the control section 20, the control section 20 determines that the leakage detecting section 22 may not detect the leakage (NO of S26), and illuminates the error indicator LP2. Next, the user is notified of the abnormality of the leakage detecting operation (S27).

另一方面，當漏電偵測信號輸入至控制部分20之輸入端子PI1時，控制部分20判定漏電偵測部分22正常地偵測到漏電(S26之"是")，且接著移動至繼電器RY1之熔融結合檢查。當漏電偵測部分22偵測到漏電時，其開啟繼電器RY1。若繼電器RY1未熔融結合，則電源側線路L1以及接地側線路L2中之每一者在繼電器RY1之二次側處具有零電壓。On the other hand, when the leakage detecting signal is input to the input terminal PI1 of the control portion 20, the control portion 20 determines that the leakage detecting portion 22 normally detects the electric leakage ("YES" of S26), and then moves to the relay RY1. Melt bond inspection. When the leakage detecting portion 22 detects a leak, it turns on the relay RY1. If the relay RY1 is not melt-bonded, each of the power source side line L1 and the ground side line L2 has a zero voltage at the secondary side of the relay RY1.

如上文所描述，L側電壓偵測器23以及N側電壓偵測器24偵測電源側線路L1以及接地側線路L2是否具有各別預定臨限值或各別預定臨限值以上的電壓。控制部分20基於電壓偵測器23與24兩者之偵測結果而檢查是否發生熔融結合(S28)。亦即，當繼電器RY1之二次側處的電源側線路L1以及接地側線路L2具有預定臨限值或預定臨限值以上的電壓時，控制部分20判定繼電器RY1熔融結合，且藉由點亮錯誤指示燈LP而告知繼電器RY1之熔融結合(S29)。As described above, the L-side voltage detector 23 and the N-side voltage detector 24 detect whether the power supply side line L1 and the ground side line L2 have voltages of respective predetermined thresholds or respective predetermined thresholds. The control section 20 checks whether fusion bonding occurs based on the detection results of both of the voltage detectors 23 and 24 (S28). That is, when the power source side line L1 and the ground side line L2 at the secondary side of the relay RY1 have a voltage above a predetermined threshold or a predetermined threshold, the control portion 20 determines that the relay RY1 is fusion-bonded and is lit by The error indicator LP informs the fusion bonding of the relay RY1 (S29).

另一方面，當繼電器RY1之二次側處的電源側線路L1以及接地側線路L2具有小於各別預定臨限值之電壓時，控制部分20判定繼電器RY1未熔融結合(繼電器RY1正常開啟)，且錯誤指示燈LP2保持斷開。此時，控制部分20控制信號輸出部分27輸出具有電壓+12V(狀態A)之CPLT信號，且返回至車輛連接等待狀態(S30)。On the other hand, when the power source side line L1 and the ground side line L2 at the secondary side of the relay RY1 have voltages smaller than the respective predetermined thresholds, the control portion 20 determines that the relay RY1 is not melt-bonded (the relay RY1 is normally turned on), And the error indicator LP2 remains off. At this time, the control section 20 controls the signal output section 27 to output a CPLT signal having a voltage of +12 V (state A), and returns to the vehicle connection waiting state (S30).

當按壓提供於電源供應控制元件1上之操作停止按鈕B2(操作停止部分)時，控制部分20移動至停止電源供應之程序。下文將參看圖5C描述此操作。When the operation stop button B2 (operation stop portion) provided on the power supply control element 1 is pressed, the control portion 20 moves to the procedure of stopping the power supply. This operation will be described below with reference to FIG. 5C.

在將電源自電源供應控制元件1供應至電動車輛100之狀態下，CPLT信號處於狀態D(圖5A之S11)。當在此狀態下按壓操作停止按鈕B2時(S31)，控制部分20控制漏電產生部分28模擬虛擬漏電以回應操作停止按鈕B2之按壓操作(停止指令)(S32)。此時，當漏電偵測部分22正常操作且偵測到漏電時，漏電偵測部分22開啟繼電 器RY1且將漏電偵測信號輸出至控制部分20之輸入端子PI1。In a state where the power source is supplied from the power supply control element 1 to the electric vehicle 100, the CPLT signal is in the state D (S11 of Fig. 5A). When the operation stop button B2 is pressed in this state (S31), the control portion 20 controls the leakage generating portion 28 to simulate the virtual leakage in response to the pressing operation (stop instruction) of the operation stop button B2 (S32). At this time, when the leakage detecting portion 22 operates normally and a leak is detected, the leakage detecting portion 22 turns on the relay. The RY1 and the leakage detecting signal are output to the input terminal PI1 of the control portion 20.

在由漏電產生部分28模擬虛擬漏電之後，控制部分20監視漏電偵測信號是否輸入至輸入端子PI1，且判定漏電偵測是否正常操作。After the virtual leakage is simulated by the leakage generating portion 28, the control portion 20 monitors whether or not the leakage detecting signal is input to the input terminal PI1, and determines whether the leakage detecting is normally operated.

當無漏電偵測信號輸入時，控制部分20判定漏電偵測部分22未能偵測到漏電(S33中之"否")，且藉由點亮錯誤指示燈LP2而向使用者告知漏電偵測操作之異常(S34)。When no leakage detection signal is input, the control section 20 determines that the leakage detecting section 22 fails to detect the leakage (NO in S33), and informs the user of the leakage detection by lighting the error indicator LP2. Abnormal operation (S34).

另一方面，當輸入漏電偵測信號時，控制部分20判定漏電偵測部分22可正常地偵測到漏電(S33之"是")，且接著移動至繼電器RY1之熔融結合檢查。當偵測到漏電時，漏電偵測部分22開啟繼電器RY1。因此，若繼電器RY1中不存在熔融結合，則電源側線路L1以及接地側線路L2中之每一者在繼電器RY1之二次側處具有零電壓。On the other hand, when the leakage detecting signal is input, the control portion 20 determines that the leakage detecting portion 22 can normally detect the electric leakage ("YES" of S33), and then moves to the fusion bonding check of the relay RY1. When the leakage is detected, the leakage detecting portion 22 turns on the relay RY1. Therefore, if there is no fusion bonding in the relay RY1, each of the power source side line L1 and the ground side line L2 has a zero voltage at the secondary side of the relay RY1.

如上文所描述，L側電壓偵測器23以及N側電壓偵測器24偵測電源側線路L1以及接地側線路L2是否在繼電器RY1之二次側處具有各別預定臨限值或各別預定臨限值以上的電壓。控制部分20基於電壓偵測器23與24兩者之偵測結果而判定是否發生熔融結合(S35)。亦即，當電源側線路L1以及接地側線路L2在繼電器RY1之二次側處具有等於或大於預定臨限值之電壓時，控制部分20判定繼電器RY1熔融結合(S35之是)，且藉由接通錯誤指示燈LP2而告知繼電器RY1之熔融結合(S36)。As described above, the L-side voltage detector 23 and the N-side voltage detector 24 detect whether the power supply side line L1 and the ground side line L2 have respective predetermined thresholds or respective differences at the secondary side of the relay RY1. The voltage above the threshold is predetermined. The control section 20 determines whether or not fusion bonding occurs based on the detection results of both of the voltage detectors 23 and 24 (S35). That is, when the power source side line L1 and the ground side line L2 have a voltage equal to or greater than a predetermined threshold value at the secondary side of the relay RY1, the control portion 20 determines that the relay RY1 is fusion-bonded (YES of S35), and by The error indicator LP2 is turned on to inform the fusion bonding of the relay RY1 (S36).

另一方面，當繼電器RY1之二次側處的電源側線路L1以及接地側線路L2之電壓小於預定臨限值時，控制部分20判定繼電器RY1未熔融結合(繼電器RY1開啟)，且錯誤指示燈LP2保持斷開。此時，控制部分20控制信號輸出部分27以將CPLT信號改變至0V，且向電動車輛100側告知電源供應已停止(S37)。On the other hand, when the voltages of the power source side line L1 and the ground side line L2 at the secondary side of the relay RY1 are less than the predetermined threshold value, the control portion 20 determines that the relay RY1 is not melted (the relay RY1 is turned on), and the error indicator lamp LP2 remains disconnected. At this time, the control section 20 controls the signal output section 27 to change the CPLT signal to 0 V, and informs the electric vehicle 100 side that the power supply has been stopped (S37).

在上文所描述之實施例中，當自電動車輛100輸入充電完成信號時，當控制部分20藉由未偵測到狀態通知信號而判定車輛側插頭P2與電動車輛100斷開時，且當在電源供應控制元件1側按壓操作停止按鈕B2時，電源饋送控制元件1藉由模擬虛擬漏電而檢查漏電偵測之操作以及繼電器RY1之熔融結合。因此，可防止增加開啟及關閉繼電器RY1之次數。In the embodiment described above, when the charging completion signal is input from the electric vehicle 100, when the control portion 20 determines that the vehicle side plug P2 is disconnected from the electric vehicle 100 by not detecting the state notification signal, and when When the operation stop button B2 is pressed on the side of the power supply control element 1, the power feeding control element 1 checks the operation of the leakage detection and the fusion bonding of the relay RY1 by simulating the virtual leakage. Therefore, it is possible to prevent an increase in the number of times the relay RY1 is turned on and off.

關於繼電器RY1之熔融結合，控制部分20基於L側電壓偵測器23以及N側電壓偵測器24之偵測結果而判定當開啟繼電器RY1時是否在繼電器RY1之二次側中產生電壓。圖6展示用於解釋在完成充電時之時間進行的漏電偵測部分22之檢查操作以及繼電器RY1之熔融結合檢查操作的時序圖。Regarding the fusion bonding of the relay RY1, the control portion 20 determines whether or not a voltage is generated in the secondary side of the relay RY1 when the relay RY1 is turned on based on the detection results of the L-side voltage detector 23 and the N-side voltage detector 24. Fig. 6 shows a timing chart for explaining the inspection operation of the leakage detecting portion 22 and the fusion bonding inspection operation of the relay RY1 performed at the time when the charging is completed.

在完成充電時之時間t1，在電動車輛100側處，CPLT信號之電壓位準自+6V改變至+9V。在時間t2，當自CPLT信號改變時起確認信號消逝需約30mS之時間週期時，控制部分20控制漏電產生部分28模擬虛擬漏電。At time t1 when charging is completed, at the side of the electric vehicle 100, the voltage level of the CPLT signal is changed from +6V to +9V. At time t2, when the acknowledgment signal elapses from the CPLT signal for a time period of about 30 mS, the control section 20 controls the leakage generating portion 28 to simulate the virtual leakage.

當偵測到漏電時，漏電偵測部分22將漏電偵測信號 輸出至控制部分20且開啟繼電器RY1。在時間t3，當自t2起已經過預定時間週期時，控制部分20檢查漏電偵測部分22之操作。另外，於時間t2起經過預定時間週期DT2後，控制部分20在時間T5檢查繼電器RY1之熔融結合。When the leakage is detected, the leakage detecting portion 22 will detect the leakage current It is output to the control section 20 and the relay RY1 is turned on. At time t3, when a predetermined period of time has elapsed since t2, the control section 20 checks the operation of the leakage detecting portion 22. Further, after a predetermined time period DT2 elapses from time t2, the control portion 20 checks the fusion bonding of the relay RY1 at time T5.

本實施例中，控制部分20基於L側電壓偵測器23以及N側電壓偵測器24之偵測結果而判定繼電器RY1是否熔融結合。在L側電壓偵測器23中，分壓電源側線路L1之電壓且接著藉由電容器C2以及C3使所述電壓平滑以提供直流(direct current；DC)電壓，將所述DC電壓與參考電壓相比較。在N側電壓偵測器24中，分壓接地側線路L2之電壓且接著藉由電容器C12以及C13使所述電壓平滑以提供DC電壓，將所述DC電壓與參考電壓相比較。In the present embodiment, the control portion 20 determines whether the relay RY1 is fusion-bonded based on the detection results of the L-side voltage detector 23 and the N-side voltage detector 24. In the L-side voltage detector 23, the voltage of the power supply side line L1 is divided and then the voltage is smoothed by capacitors C2 and C3 to provide a direct current (DC) voltage, which is compared with a reference voltage. Compared. In the N-side voltage detector 24, the voltage of the ground side line L2 is divided and then the voltage is smoothed by capacitors C12 and C13 to provide a DC voltage, which is compared with a reference voltage.

因此，在開啟繼電器RY1之後，電容器中之殘餘電荷將導致發生時間遲滯，直至兩個電壓偵測器23與24之輸出變為L位準為止。由於時間遲滯隨著電容器容量而改變，故有必要將預定時間DT2設定為比時間遲滯長。因此，在檢查熔融結合之前花費較長時間。Therefore, after the relay RY1 is turned on, the residual charge in the capacitor will cause a time lag until the output of the two voltage detectors 23 and 24 becomes the L level. Since the time lag changes with the capacity of the capacitor, it is necessary to set the predetermined time DT2 to be longer than the time lag. Therefore, it takes a long time before checking the fusion bonding.

為了解決此問題，如圖7中所展示，可提供開關元件Q1以及開關元件Q2，開關元件Q1用於使儲存於L側電壓偵測器23之電容器C2以及C3中之電荷放電，且開關元件Q2用於使儲存於N側電壓偵測器24之電容器C12以及C13中之電荷放電。亦即，分別經由由包含開關元件Q1以及Q2之放電電路部分提供的放電路徑使儲存於電容器C2、C3以及電容器C12、C13中之電荷放電。此等開 關元件Q1以及Q2通常為關閉(normally turn off)的狀態。在本發明實施例中，開關元件Q1以及Q2由電晶體形成，但可包含不同於電晶體之開關元件。In order to solve this problem, as shown in FIG. 7, a switching element Q1 for discharging electric charges stored in the capacitors C2 and C3 of the L-side voltage detector 23, and a switching element Q2, and a switching element Q2 is for discharging the electric charges stored in the capacitors C12 and C13 of the N-side voltage detector 24. That is, the charges stored in the capacitors C2, C3 and the capacitors C12, C13 are discharged via the discharge paths provided by the discharge circuit portions including the switching elements Q1 and Q2, respectively. This opening The off components Q1 and Q2 are normally in a normally turned off state. In the embodiment of the present invention, the switching elements Q1 and Q2 are formed of a transistor, but may include a switching element different from the transistor.

當漏電產生部分28在檢查漏電偵測之操作以及熔融結合時模擬虛擬漏電時，控制部分20在提供放電路徑之時間週期內接通開關元件Q1、Q2。當接通開關元件Q1時，使儲存於電容器C2、C3中之電荷放電。當接通開關元件Q2時，使儲存於電容器C12、C13中之電荷放電。此情形縮短了在L側電壓偵測器23以及N側電壓偵測器24之偵測結果改變至L位準之前的時間遲滯，藉此減少了檢查熔融結合之前的時間遲滯。When the leakage generating portion 28 simulates the virtual leakage while checking the operation of the leakage detection and the fusion bonding, the control portion 20 turns on the switching elements Q1, Q2 during the period in which the discharge path is supplied. When the switching element Q1 is turned on, the electric charges stored in the capacitors C2, C3 are discharged. When the switching element Q2 is turned on, the electric charges stored in the capacitors C12, C13 are discharged. This situation shortens the time lag before the detection result of the L-side voltage detector 23 and the N-side voltage detector 24 changes to the L level, thereby reducing the time lag before checking the fusion bonding.

將參看圖8中所展示之時序圖描述此操作。當在時間t11在電動車輛100中完成充電時，在電動車輛100側處，CPLT信號之電壓位準自+6V改變至+9V。在時間t12，亦即，在自CPLT信號改變時起約30mS之後，信號變成穩定的。This operation will be described with reference to the timing chart shown in FIG. When charging is completed in the electric vehicle 100 at time t11, at the side of the electric vehicle 100, the voltage level of the CPLT signal is changed from +6 V to +9 V. At time t12, that is, after about 30 mS from the time when the CPLT signal is changed, the signal becomes stable.

在時間t12，控制部分20控制漏電產生部分28以模擬虛擬漏電。當偵測到此漏電時，漏電偵測部分22將漏電偵測信號輸出至控制部分20且開啟繼電器RY1。另外，在由漏電產生部分28模擬虛擬漏電之後，控制部分20在自時間t13至時間t15之時間週期期間接通開關元件Q1、Q2，藉此使儲存於L側電壓偵測器23之電容器C2以及C3中以及N側電壓偵測器24之電容器C12以及C13中的電荷放電。At time t12, the control section 20 controls the leakage generating portion 28 to simulate virtual leakage. When the leakage is detected, the leakage detecting portion 22 outputs the leakage detecting signal to the control portion 20 and turns on the relay RY1. Further, after the dummy leakage is simulated by the leakage generating portion 28, the control portion 20 turns on the switching elements Q1, Q2 during the time period from time t13 to time t15, thereby causing the capacitor C2 stored in the L-side voltage detector 23 And the charge discharge in the capacitors C12 and C13 in the C3 and N-side voltage detectors 24.

此外，在自時間t12起已經過預定時間週期時的時間t13，控制部分20檢查漏電偵測之操作。此外，在於時間t15之後經過預定時間週期DT5後的時間t16，控制部分20檢查熔融結合，在時間t15，斷開開關元件Q1、Q2。Further, the control section 20 checks the operation of the leakage detection at time t13 when the predetermined time period has elapsed since time t12. Further, the control portion 20 checks the fusion bonding at time t16 after the predetermined time period DT5 elapses after the time t15, and turns off the switching elements Q1, Q2 at time t15.

本實施例中，將時間週期DT4(自產生漏電時之時間開始至斷開開關元件Q1、Q2時之時間)設定為藉由將以下兩者相加而獲得的時間週期(例如，130mS)：在繼電器RY1正常開啟之狀況下，模擬虛擬漏電所需的時間週期(例如，50mS)，與使儲存於L側電壓偵測器23以及N側電壓偵測器24之電容器中之電荷放電所需的時間週期(例如，80mS)。另外，在繼電器RY1熔融結合之狀況下，在時間t15斷開開關元件Q1、Q2，且對L側電壓偵測器23以及N側電壓偵測器24之電容器充電。本實施例中，將L側電壓偵測器23以及N側電壓偵測器24之輸出改變至H位準需要特定時間量。In the present embodiment, the time period DT4 (the time from the time when the leakage is generated to the time when the switching elements Q1 and Q2 are turned off) is set as the time period (for example, 130 mS) obtained by adding the following two: In the condition that the relay RY1 is normally turned on, the time period required for simulating the virtual leakage (for example, 50 mS), and the discharge of the electric charge stored in the capacitors of the L-side voltage detector 23 and the N-side voltage detector 24 are required. Time period (for example, 80mS). Further, in a state where the relay RY1 is fusion-bonded, the switching elements Q1, Q2 are turned off at time t15, and the capacitors of the L-side voltage detector 23 and the N-side voltage detector 24 are charged. In this embodiment, it takes a certain amount of time to change the output of the L-side voltage detector 23 and the N-side voltage detector 24 to the H level.

由於彼原因，故可在檢查熔融結合之前提供特定等待時間。舉例而言，當電源供應85V之電壓時，等待時間不超過100mS。因此，可將在斷開開關元件Q1、Q2之後在檢查熔融結合之前所需的等待時間週期DT5設定為100mS。因此，例如，可將在模擬虛擬漏電之後在檢查熔融結合之前的總的時間週期設定為230mS(DT4(=130mS)與DT5(=100mS)之總和)。因此，與如圖6中所展示之序列之總時間相比較，可減少總時間，藉此使得在繼電器RY1熔融結合之狀況下較快地偵測以及宣告熔融結合。此 情形可改良安全性。For some reason, a specific waiting time can be provided before checking the fusion bond. For example, when the power supply supplies a voltage of 85V, the waiting time does not exceed 100mS. Therefore, the waiting time period DT5 required before the switching of the switching elements Q1, Q2 before checking the fusion bonding can be set to 100 mS. Thus, for example, the total time period before the fusion bonding is checked after the simulated virtual leakage can be set to 230 mS (the sum of DT4 (= 130 mS) and DT5 (= 100 mS)). Therefore, the total time can be reduced as compared with the total time of the sequence as shown in Fig. 6, whereby the fusion bonding is detected and declared faster in the case where the relay RY1 is melt-bonded. this The situation can improve security.

甚至當在繼電器RY1熔融結合之狀態下斷開車輛側插頭P2時，車輛側插頭P2亦得到電源。在本發明實施例之情況下，由於可在完成由使用者斷開車輛側插頭P2(例如，一秒)之前執行關於熔融結合之檢查以及告知，故可改良安全性。應注意，「電器用品以及材料安全」要求：在將插頭插腳自插腳接收器移除之後的一秒內，插頭接腳上之電壓必須為45V或小於45V。如上文所描述，在本發明實施例中，由於可在一秒內檢查以及告知熔融結合，故足以確保安全性。Even when the vehicle side plug P2 is disconnected in a state where the relay RY1 is fusion-bonded, the vehicle-side plug P2 is also powered. In the case of the embodiment of the present invention, since the inspection and the notification regarding the fusion bonding can be performed before the completion of the disconnection of the vehicle side plug P2 by the user (for example, one second), the safety can be improved. It should be noted that "Electrical Appliances and Material Safety" requires that the voltage on the plug pins must be 45V or less than 45V within one second after the plug pins are removed from the pin receiver. As described above, in the embodiment of the present invention, since it is possible to inspect and inform the fusion bonding in one second, it is sufficient to ensure safety.

另外，在上述電源饋送控制元件1中，儘管皆在停止電源供應時模擬虛擬漏電來檢查漏電偵測部分22之操作與熔融結合兩者，但可在開始電源供應時執行漏電偵測部分22之檢查操作。將參看圖9中所展示之時序圖描述此操作。Further, in the above-described power feeding control element 1, although the virtual leakage is simulated to check both the operation and the fusion of the leakage detecting portion 22 when the power supply is stopped, the leakage detecting portion 22 can be executed at the time of starting the power supply. Check the operation. This operation will be described with reference to the timing chart shown in FIG.

當使用者將電源側插頭P1***至電源插座中時，商用AC電源之電源供應至電源饋送控制元件1且電源饋送控制元件1開始操作。在無車輛側插頭P2連接至電動車輛100之狀態下，自信號輸出部分27輸出之CPLT信號具有電壓+12V(狀態A)，且CPLT信號輸入至信號輸入部分26中(S50)。在此時，控制部分20基於自信號輸入部分26輸入之CPLT信號而判定無車輛側插頭P2連接至電動車輛100。When the user inserts the power source side plug P1 into the power socket, the power of the commercial AC power source is supplied to the power source control element 1 and the power source control element 1 starts operating. In a state where the vehicle-less side plug P2 is connected to the electric vehicle 100, the CPLT signal output from the signal output portion 27 has a voltage of +12 V (state A), and the CPLT signal is input to the signal input portion 26 (S50). At this time, the control section 20 determines that the vehicle-less side plug P2 is connected to the electric vehicle 100 based on the CPLT signal input from the signal input section 26.

接下來，當使用者將車輛側插頭P2***至電動車輛 100之插座101中時(S51)，輸入至信號輸入部分26之CPLT信號之電壓改變成+9V(狀態B)。Next, when the user inserts the vehicle side plug P2 into the electric vehicle At the time of the socket 101 of 100 (S51), the voltage of the CPLT signal input to the signal input portion 26 is changed to +9 V (state B).

當CPLT信號改變成狀態B時(S52中之"是")，電源饋送控制元件1之控制部分20判定車輛側插頭P2連接至電動車輛100，且控制漏電產生部分28模擬虛擬漏電(S53)。此時，當正常操作時，漏電偵測部分22偵測漏電且將漏電偵測信號輸出至控制部分20之輸入端子PI1。When the CPLT signal is changed to the state B (YES in S52), the control portion 20 of the power feeding control element 1 determines that the vehicle side plug P2 is connected to the electric vehicle 100, and the control leakage generating portion 28 simulates virtual leakage (S53). At this time, when operating normally, the leakage detecting portion 22 detects the leakage and outputs the leakage detecting signal to the input terminal PI1 of the control portion 20.

在控制漏電產生部分28以模擬虛擬漏電之後，控制部分20監視漏電偵測信號是否輸入至輸入端子PI1。當無漏電偵測信號輸入時，控制部分20判定漏電偵測部分22無法偵測到漏電(S54中之"否")，且藉由點亮錯誤指示燈LP2而向使用者告知漏電偵測錯誤(S55)。After controlling the leakage generating portion 28 to simulate the virtual leakage, the control portion 20 monitors whether or not the leakage detecting signal is input to the input terminal PI1. When no leakage detection signal is input, the control section 20 determines that the leakage detecting section 22 cannot detect the leakage (NO in S54), and notifies the user of the leakage detection error by lighting the error indicator LP2. (S55).

另一方面，當漏電偵測信號輸入至控制部分20之輸入端子PI1時，控制部分20判定漏電偵測部分22可正常地偵測到漏電(S54中之"是")，且移動至充電啟用等待狀態。接著，控制部分20控制信號輸出部分27以將CPLT信號改變成狀態C(S56)。On the other hand, when the leakage detecting signal is input to the input terminal PI1 of the control portion 20, the control portion 20 determines that the leakage detecting portion 22 can normally detect the electric leakage ("YES" in S54), and moves to the charging enable. Waiting state. Next, the control section 20 controls the signal output section 27 to change the CPLT signal to the state C (S56).

當CPLT信號改變成狀態C時，電動車輛100之充電電路103判定電源饋送控制元件1處於充電致能等待狀態，且使得用於致能充電之開關可操作。當在電動車輛100側處接通用於致能充電之開關時，在電動車輛100側處，CPLT信號之電壓位準改變至+6V，且將用於啟用充電之信號輸出至電源饋送控制元件1。When the CPLT signal is changed to the state C, the charging circuit 103 of the electric vehicle 100 determines that the power feeding control element 1 is in the charge enable waiting state, and makes the switch for enabling charging operable. When the switch for enabling charging is turned on at the side of the electric vehicle 100, at the side of the electric vehicle 100, the voltage level of the CPLT signal is changed to +6 V, and a signal for enabling charging is output to the power feeding control element 1 .

當CPLT信號之電壓位準改變至+6V時(S57中之 是)，控制部分20判定對電動車輛100之充電被致能，且控制信號輸出部分27將CPLT信號改變成狀態D(S58)。另外，控制部分20控制繼電器驅動單元25關閉繼電器RY1，藉此開始充電(S59)。When the voltage level of the CPLT signal changes to +6V (S57) Yes), the control section 20 determines that charging of the electric vehicle 100 is enabled, and the control signal output section 27 changes the CPLT signal to the state D (S58). Further, the control section 20 controls the relay drive unit 25 to turn off the relay RY1, thereby starting charging (S59).

如上文所描述，在電源供應至電動車輛100之前繼電器RY1開啟之狀態下，將用於告知車輛側插頭P2***至電動車輛100之插座101中的連接確認信號(+9V之CPLT信號)輸入至信號輸入部分26，連接確認信號(+9V之CPLT信號)作為狀態通知信號。此時，控制部分20控制漏電產生部分28模擬虛擬漏電。As described above, in a state where the relay RY1 is turned on before the power is supplied to the electric vehicle 100, a connection confirmation signal (the CPLT signal of +9 V) for informing the vehicle side plug P2 to be inserted into the outlet 101 of the electric vehicle 100 is input to The signal input portion 26 is connected to the acknowledgment signal (the CPLT signal of +9 V) as a status notification signal. At this time, the control section 20 controls the leakage generating portion 28 to simulate virtual leakage.

因此，電源饋送控制元件1可在開始至電動車輛100之電源供應之前判定漏電偵測部分22是否正常操作。因此，在檢查到漏電偵測部分22正常操作之後，可開始電源供應。另外，由於在繼電器RY1開啟之狀態下模擬虛擬漏電，故在偵測漏電時不必要開啟繼電器RY1。因此，開啟及關閉繼電器RY1之次數得以減小，並可藉以防止電源饋送控制元件1之壽命縮短。Therefore, the power feeding control element 1 can determine whether the leakage detecting portion 22 is normally operated before starting the power supply to the electric vehicle 100. Therefore, after checking that the leakage detecting portion 22 is normally operated, the power supply can be started. In addition, since the virtual leakage is simulated in the state where the relay RY1 is turned on, it is not necessary to turn on the relay RY1 when detecting the leakage. Therefore, the number of times the relay RY1 is turned on and off can be reduced, and the life of the power feeding control element 1 can be prevented from being shortened.

在上述實施例中，儘管攜帶型電源饋送控制元件1用於連接至電源插座，但電源饋送控制元件1可為落地式。舉例而言，如圖11中所展示，圖1中所展示之電路部分可建置於安裝於停車空間附近的直立型之主體部分10中，或建置於附接於諸如房屋之住宅之壁上的主體部分10中。在直立型之此電源饋送控制元件1中，可提前將來自電源之佈線連接至繼電器RY1之一次側，此情形消除了對於連接 於電源與電源側插頭P1之間的電纜CB1之需要。In the above embodiment, although the portable power feeding control element 1 is used for connection to a power outlet, the power feeding control element 1 may be of a floor type. For example, as shown in FIG. 11, the circuit portion shown in FIG. 1 can be built into an upright body portion 10 that is mounted near a parking space, or built into a wall that is attached to a house such as a house. In the main body part 10 above. In the power supply control element 1 of the upright type, the wiring from the power supply can be connected to the primary side of the relay RY1 in advance, which eliminates the connection for the case. The cable CB1 between the power supply and the power supply side plug P1 is required.

雖然已關於實施例展示並描述了本發明，但熟習此項技術者應理解，可在不脫離如以下申請專利範圍中所定義的本發明之範疇的情況下，作出各種改變及修改。While the present invention has been shown and described with respect to the embodiments of the invention, it will be understood by those skilled in the art that various changes and modifications can be made without departing from the scope of the invention as defined in the following claims.
