Description
本案係關於一種充電方法，尤指一種可快速充電，且減少充電裝置之生產成本之充電方法及其適用之充電裝置。 The present invention relates to a charging method, and more particularly to a charging method capable of quickly charging and reducing the production cost of a charging device and a charging device therefor.
可攜式電子裝置，例如手機等，已廣泛應用於人們的日常生活中，可攜式電子裝置通常利用可充電之電池單元作為電源。由於可攜式電子裝置的體積和電池單元的容量有限，因此需要利用一充電裝置對電池單元進行充電，使可攜式電子裝置可重複性使用。 Portable electronic devices, such as mobile phones, have been widely used in people's daily lives, and portable electronic devices typically utilize rechargeable battery cells as a power source. Since the size of the portable electronic device and the capacity of the battery unit are limited, it is necessary to charge the battery unit with a charging device, so that the portable electronic device can be used repeatedly.
而傳統充電方法或裝置中係具有多種實施態樣，其中第一種傳統的充電方法及其適用的充電裝置係利用一種多段式充電來為複數個電芯並聯組之電池模組進行充電，亦即如中華民國I343141號專利所述，其充電方法及充電裝置的技術手段乃是先以第一預設電流對具有複數個電芯並聯組之電池模組進行定電流充電，接著於充電過程中，判斷電池模組之複數個電芯並聯組的個別電壓是否到達第一預設電壓，當任何一個電芯並聯組之充電電壓到達第一預設電壓時，改以第二預設電流對電池模組進行定電流充電，接著判斷電池模組之複數個電芯並聯組的個別電壓是否到達第二預設電壓，並當任一電芯並聯組之充電電壓到達第二預設電壓時 ，改以第二預設電壓對電池模組進行定電壓充電，並維持以第二預設電壓進行定電壓充電，直至電池模組之電力充飽為止。 The conventional charging method or device has various implementations, wherein the first conventional charging method and the applicable charging device utilize a multi-stage charging to charge a battery module of a plurality of battery parallel groups. That is, as described in the Patent No. I343141 of the Republic of China, the charging method and the technical means of the charging device are to firstly charge a battery module having a plurality of parallel groups of cells with a first preset current, and then during charging. And determining whether the individual voltages of the plurality of battery parallel groups of the battery module reach the first preset voltage, and when the charging voltage of any one of the parallel groups of the batteries reaches the first preset voltage, changing the battery to the second preset current The module performs constant current charging, and then determines whether the individual voltages of the plurality of battery parallel groups of the battery module reach the second preset voltage, and when the charging voltage of any of the battery parallel groups reaches the second preset voltage The battery module is fixedly charged by the second preset voltage, and the constant voltage is charged by the second preset voltage until the power of the battery module is full.
然而第一種傳統的充電方法或充電裝置，如果欲達到目前使用者普遍所要求的快速充電之需求時，僅能朝加大電池模組所接收之第一預設電流或第二預設電流之電流值的方式來設計，如此一來，提供第一預設電流或第二預設電流之一供電電路勢必須對應改其內部之電路結構，導致提供第一預設電流或第二預設電流之電路必須重新模組化而具有較高的生產成本，此外，若欲使該供電電路輸出較大的充電電流，則供電電路內部的電子元件勢必選用耐電流等級較高的電子元件來達成，亦造成供電電路及充電裝置之生產成本提高。更甚者，由於第一種傳統的充電方法或充電裝置需判斷電池模組之複數個電芯並聯組的個別電壓是否到達第一預設電壓或第二預設電壓，故必然需使用可偵測電壓之一偵測電路，亦使得充電裝置因偵測電路而成本提高。 However, the first conventional charging method or charging device can only increase the first preset current or the second preset current received by the battery module if it is required to meet the fast charging requirements generally required by the current user. The current value is designed in such a manner that one of the first preset current or the second preset current supply circuit potential must correspond to the internal circuit structure, resulting in providing the first preset current or the second preset The circuit of the current must be re-modularized and has a high production cost. In addition, if the power supply circuit is to output a large charging current, the electronic components inside the power supply circuit are necessarily selected by using electronic components with higher current resistance levels. It also causes an increase in the production cost of the power supply circuit and the charging device. Moreover, since the first conventional charging method or charging device needs to determine whether the individual voltages of the plurality of battery parallel groups of the battery module reach the first preset voltage or the second preset voltage, it is necessary to use the detectable One of the voltage detecting circuits detects the cost of the charging device due to the detecting circuit.
而第二種傳統的充電方法及其適用之充電裝置則可參考中華民國M381951號專利，其係揭露一種雙模充電電路，係包含第一充電路徑、第二充電路徑、模式切換電路及中央處理單元，其中第一充電路徑係為慢速充電路徑，第二充電路徑係與第一充電路徑並行連接於外部電源與電池之間，且為快速充電路徑，中央處理單元則與電池相連，用以偵測電池電量，且判斷偵測到的電池電量是否超過預設值，並根據判斷結果輸出模式控制訊號，至於模式切換電路，則連接於中央處理單元及第二充電路徑之間，用於根據模式控制訊號控制第二充電路徑的導通與斷開，藉此當第二充電路徑斷開時，第一充電路徑單獨以慢速充電模式對電池進行充 電，而當第二充電路徑導通時，第一充電路徑與第二充電路徑共同以快速充電模式對電池模組進行充電。 The second conventional charging method and its applicable charging device can refer to the Republic of China M381951 patent, which discloses a dual-mode charging circuit including a first charging path, a second charging path, a mode switching circuit, and a central processing. The unit, wherein the first charging path is a slow charging path, the second charging path is connected in parallel with the first charging path between the external power source and the battery, and is a fast charging path, and the central processing unit is connected to the battery for Detecting the battery power, determining whether the detected battery power exceeds a preset value, and outputting a mode control signal according to the determination result; and the mode switching circuit is connected between the central processing unit and the second charging path for The mode control signal controls the conduction and disconnection of the second charging path, whereby when the second charging path is disconnected, the first charging path separately charges the battery in the slow charging mode. When the second charging path is turned on, the first charging path and the second charging path jointly charge the battery module in the fast charging mode.
雖然第二種傳統的充電裝置可達到快速充電之需求，然而由於第二種傳統的充電裝置需設置中央處理單元，並利用中央處理單元來偵測電池電量之變化，且須設置模式切換電路，以利用模式切換電路控制第一充電路徑、第二充電路徑進行導通或斷開之切換，故第二種傳統的充電裝置仍因使用中央處理單元及模式切換電路而存在生產成本較高之問題。 Although the second conventional charging device can meet the requirement of fast charging, the second conventional charging device needs to set a central processing unit, and uses a central processing unit to detect changes in battery power, and a mode switching circuit must be provided. In the mode switching circuit, the first charging path and the second charging path are controlled to be switched on or off. Therefore, the second conventional charging device still has a problem of high production cost due to the use of the central processing unit and the mode switching circuit.
因此，如何發展一種可改善上述習知技術缺失之充電方法及其適用之充電裝置，實為相關技術領域者目前所迫切需要解決之問題。 Therefore, how to develop a charging method which can improve the above-mentioned conventional technology and a charging device to which it is applied is an urgent problem to be solved by those skilled in the related art.

It is to be understood that the present invention is capable of various modifications in the various aspects of the present invention, and the description and drawings are intended to be illustrative and not limiting.
請參閱第1圖，其係為本案較佳實施例之充電裝置的電路結構示意圖。如第1圖所示，本實施例之充電裝置10係與一電源供應單元11及一電池單元12電連接，用以接收電源供應單元11所提供之輸入電能Vin，並將輸入電能Vin進行轉換，以輸出充電電能對電池單元12進行充電。 Please refer to FIG. 1 , which is a schematic diagram of the circuit structure of the charging device of the preferred embodiment of the present invention. As shown in FIG. 1 , the charging device 10 of the present embodiment is electrically connected to a power supply unit 11 and a battery unit 12 for receiving input power Vin provided by the power supply unit 11 and converting the input power Vin. The battery unit 12 is charged by outputting charging power.
充電裝置10係包含複數個充電積體電路，例如第1圖所示之三個充電積體電路111、112、113，其中複數個充電積體電路111、112、113之輸入端係並聯連接，且與電源供應單元11電連接而接收輸入電能Vin，此外，複數個充電積體電路111、112、113之輸出端亦並聯連接，且與電池單元12電連接，每一充電積體電路(111、112、113)係具有對應之電壓門檻值，且可將輸入電能Vin轉換，以輸出充電電壓Vc及/或充電電流Ic至電池單元12，另外，每一充電積體電路係以混合式充電方式進行運作，換言之，即當充電裝置10開始運作而於電池單元12充電之初期，每一充電積體電路係執行一定電流模式而輸出固定的充電電流Ic對電池單元12進行充電，而當電池單元12之電壓經由充電而上升到任一充電積體電路所對應的電壓門檻值時，該對應之充電積體電路則改分別執行定電壓模式而輸出固定的充電電壓Vc對電池單元12進行充 電，此時該充電積體電路所輸出之充電電流Ic將開始下降。更甚者，於本實施例中，每一充電積體電路在分別執行定電壓模式時所輸出的充電電壓Vc的電壓值係異於其它充電積體電路在分別執行定電壓模式時所輸出的充電電壓Vc的電壓值。再者，當任一充電積體電路執行定電壓模式且輸出之充電電流Ic下降並小於一電流門檻值時，對應之該充電積體電路便分別停止運作。 The charging device 10 includes a plurality of charging integrated circuits, for example, three charging integrated circuits 111, 112, 113 shown in FIG. 1, wherein the input ends of the plurality of charging integrated circuits 111, 112, 113 are connected in parallel, And the power supply unit 11 is electrically connected to receive the input electric energy Vin. Further, the outputs of the plurality of charging integrated circuits 111, 112, 113 are also connected in parallel, and are electrically connected to the battery unit 12, and each charging integrated circuit (111) , 112, 113) have corresponding voltage threshold values, and can convert the input power Vin to output the charging voltage Vc and/or the charging current Ic to the battery unit 12. In addition, each charging integrated circuit is charged in a hybrid manner. The mode operates, in other words, when the charging device 10 starts to operate and the battery unit 12 is charged, each charging integrated circuit performs a certain current mode and outputs a fixed charging current Ic to charge the battery unit 12, and when the battery When the voltage of the unit 12 rises to the voltage threshold corresponding to any of the charging integrated circuits via charging, the corresponding charging integrated circuit performs the constant voltage mode and outputs separately. Given charge voltage Vc of the charged battery cell 12 At this time, the charging current Ic outputted by the charging integrated circuit will start to drop. Moreover, in the present embodiment, the voltage value of the charging voltage Vc outputted by each charging integrated circuit when performing the constant voltage mode is different from that of the other charging integrated circuits when respectively performing the constant voltage mode. The voltage value of the charging voltage Vc. Furthermore, when any of the charging integrated circuits performs the constant voltage mode and the output charging current Ic falls below a current threshold, the charging integrated circuits are respectively stopped.
於其它實施例中，每一充電積體電路更可在定電壓模式下且自身所輸出之充電電流Ic下降至小於電流門檻值時，於經過一預設時間後才停止運作，而藉由該預設時間的設置便可避免每一充電積體電路因充電電流Ic的浮動而導致錯誤的停止運作判別。另外，每一充電積體電路所對應的電壓門檻值實際上可相異於其它充電積體電路所對應的電壓門檻值，但不以此為限，每一充電積體電路所對應的電壓門檻值亦可相同於其它充電積體電路所對應的電壓門檻值。再者，每一充電積體電路分別執行定電流模式而輸出之充電電流Ic可相同於或相異於其它充電積體電路所輸出之充電電流Ic。 In other embodiments, each of the charging integrated circuits can stop operating after a predetermined period of time in the constant voltage mode and the charging current Ic outputted by itself decreases below the current threshold. The preset time setting can avoid the erroneous stop operation discrimination of each charging integrated circuit due to the floating of the charging current Ic. In addition, the voltage threshold corresponding to each charging integrated circuit may actually be different from the voltage threshold corresponding to other charging integrated circuits, but not limited thereto, the voltage threshold corresponding to each charging integrated circuit The value can also be the same as the voltage threshold corresponding to other charging integrated circuits. Furthermore, each of the charging integrated circuits respectively performs a constant current mode and the output charging current Ic may be the same as or different from the charging current Ic outputted by the other charging integrated circuits.
當然充電積體電路之個數並不侷限於如第1圖所示為三個，可依據電池單元12之充電需求而變更充電積體電路之數量。 Of course, the number of charging integrated circuits is not limited to three as shown in FIG. 1, and the number of charging integrated circuits can be changed depending on the charging demand of the battery unit 12.
於一些實施例中，充電積體電路111、112、113更各自具有一控制單元21、22、23，控制單元21、22、23係分別控制對應的充電積體電路111、112、113的運作，並控制對應的充電積體電路111、112、113在運作時係以混合式充電方式進行充電電能的輸出。 In some embodiments, the charging integrated circuits 111, 112, 113 each have a control unit 21, 22, 23, and the control units 21, 22, 23 respectively control the operation of the corresponding charging integrated circuits 111, 112, 113. And controlling the corresponding charging integrated circuits 111, 112, 113 to perform charging electric energy output in a hybrid charging mode during operation.
於一些實施例中，輸入電能Vin可為交流電能或直流電能。每一 充電積體電路111、112、113分別可為交流/直流轉換電路架構或直流/直流轉換電路架構。於其它實施例中，複數個控制單元21~23更可分別預先儲存可變更的該預設時間，藉此當對應之充電積體電路於充電電流Ic低於電流門檻值時，於經過預設時間後停止運作。 In some embodiments, the input electrical energy Vin can be alternating current electrical energy or direct current electrical energy. Each The charging integrated circuits 111, 112, and 113 may respectively be an AC/DC converting circuit architecture or a DC/DC converting circuit architecture. In other embodiments, the plurality of control units 21 to 23 may separately store the preset time that can be changed, thereby presetting the preset charging circuit when the charging current Ic is lower than the current threshold. Stop working after time.
請參閱第2圖，並配合第1圖，其中第2圖係為應用於第1圖所示之充電裝置的充電方法之一較佳實施例的步驟流程圖。如第1及2圖所示，首先，執行步驟S1，預先設定複數個充電積體電路111~113分別在執行定電壓模式時係輸出電壓值彼此相異的充電電壓Vc。其中在步驟S1中，可例如預先設定充電積體電路111的充電電壓Vc為4.2V，預先設定充電積體電路112的充電電壓Vc為4.1V，預先設定充電積體電路113的充電電壓Vc為4.0V。 Referring to FIG. 2, in conjunction with FIG. 1, FIG. 2 is a flow chart showing the steps of a preferred embodiment of the charging method applied to the charging device shown in FIG. 1. As shown in the first and second diagrams, first, in step S1, the plurality of charging integrated circuits 111 to 113 are set in advance to output charging voltages Vc having mutually different voltage values when the constant voltage mode is executed. In the step S1, for example, the charging voltage Vc of the charging integrated circuit 111 can be set to 4.2 V in advance, and the charging voltage Vc of the charging integrated circuit 112 is set to 4.1 V in advance, and the charging voltage Vc of the charging integrated circuit 113 is set in advance. 4.0V.
接著，執行步驟S2，於充電裝置10開始運作時，控制複數個充電積體電路分別執行定電流模式而輸出為固定值之充電電流Ic，以對電池單元12進行充電。在步驟S2中，當每一充電積體電路輸出充電電流Ic時，電池單元12所接收之電流即為複數個充電積體電路111、112、113所輸出之充電電流Ic的疊加。 Next, in step S2, when the charging device 10 starts operating, the plurality of charging integrated circuits are controlled to perform a constant current mode and output a fixed value charging current Ic to charge the battery unit 12. In step S2, when each charging integrated circuit outputs the charging current Ic, the current received by the battery unit 12 is a superposition of the charging current Ic outputted by the plurality of charging integrated circuits 111, 112, 113.
然後執行步驟S3，當電池單元12之電壓因充電而上升到等於任一充電積體電路所對應之電壓門檻值時，控制對應之該充電積體電路執行定電壓模式，以輸出為固定值之充電電壓Vc對電池單元12進行充電。接著執行步驟S4，當任一充電積體電路的充電電流Ic下降並降低於電流門檻值時，充電電流Ic低於電流門檻值之充電積體電路便停止運作，其中電流門檻值可為但不限於200毫安培。 Then, in step S3, when the voltage of the battery unit 12 rises to be equal to the voltage threshold corresponding to any of the charging integrated circuits, the control corresponding to the charging integrated circuit performs a constant voltage mode to output a fixed value. The charging voltage Vc charges the battery unit 12. Then, in step S4, when the charging current Ic of any charging integrated circuit drops and decreases to the current threshold, the charging integrated circuit whose charging current Ic is lower than the current threshold stops operating, wherein the current threshold can be but not Limited to 200 mA.
而由上可知，當複數個充電積體電路皆停止運作時，充電裝置10實際上便停止運作而結束充電。當然，於步驟S4中，由於複數個充電積體電路111~113在執行定電壓模式時係輸出電壓值彼此相異的充電電壓，例如前述之4.2V、4.1V及4.0V，因此當電池單元12之電壓因充電而逐漸上升且經由4.0V上升至4.2V時，複數個充電積體電路113~111更因自身所輸出之充電電壓達到電池單元12之電壓而在充電電流Ic低於電流門檻值時依序停止運作。 As can be seen from the above, when a plurality of charging integrated circuits are stopped, the charging device 10 actually stops operating and ends charging. Of course, in step S4, since the plurality of charging integrated circuits 111 to 113 output charging voltages having mutually different voltage values when performing the constant voltage mode, for example, the aforementioned 4.2V, 4.1V, and 4.0V, when the battery unit When the voltage of 12 gradually rises due to charging and rises to 4.2V via 4.0V, the plurality of charging integrated circuits 113-111 further reach the voltage of the battery unit 12 due to the charging voltage output by the battery, and the charging current Ic is lower than the current threshold. The values stop working in sequence.
於上述實施例中，步驟S4更可為當任一該充電積體電路的充電電流Ic下降並降低於電流門檻值時，對應之充電積體電路便於所輸出之充電電流Ic低於電流門檻值且經過預設時間後停止運作。 In the above embodiment, step S4 is that when the charging current Ic of any of the charging integrated circuits decreases and decreases to a current threshold, the corresponding charging integrated circuit facilitates the output charging current Ic to be lower than the current threshold. And after a preset time, it stops working.
以下將以第3圖來示範性說明本案充電裝置10的作動方式及原理，而為了更清楚了解本案之技術，第3圖中係標示V1、V2、V3來分別代表充電積體電路111、112、113所輸出之充電電壓，並標示I1、I2、I3來分別代表充電積體電路111、112、113所輸出之充電電流，且第3圖係以每一充電積體電路所對應的電壓門檻值相異於其它充電積體電路所對應的電壓門檻值來例示。請參閱第3圖並配合第1及2圖，其中第3圖係為第1圖所示之充電裝置在對電池單元進行充電時之電壓及電流的時序圖。如第3圖所示，在時間T0以前而充電裝置10尚未運作時，可預先設定充電積體電路111的充電電壓為V1，例如4.2V，預先設定充電積體電路112的充電電壓為V2，例如4.1V，預先設定充電積體電路113的充電電壓為V3，例如4.0V。當時間T0以後，充電裝置10便開始運作，而控制單元21、22、23則分別控制充電積體電路111、112、113執行定電流模式而輸出為固定值之充電電流I1、I2及I3，以對電池單 元12進行充電，此時電池單元12所接收之電流等於充電電流I1、I2、I3的總和(I1+I2+I3)，例如等於1.2C(C為電池單元12之容量)。而在時間T1時，電池單元12的電壓已上升至等於充電積體電路113所對應的電壓門檻值，故充電積體電路113之控制單元23便控制充電積體電路113改執行定電壓模式而輸出充電電壓V3，此時充電積體電路113所輸出之充電電流I3將開始下降。然後當到達時間T2，充電積體電路113之充電電流I3下降至低於電流門檻值後，該對應之充電積體電路113便停止運作，此時電池單元12所接收之電流便改為等於充電電流I1、I2的總和(I1+I2)，例如等於1.0C。當在時間T3時，電池單元12的電壓已上升至等於充電積體電路112所對應的電壓門檻值，故充電積體電路112之控制單元22便控制充電積體電路112改執行定電壓模式而輸出充電電壓V2，此時充電積體電路112所輸出之充電電流I2將開始下降。然後當到達時間T4，而充電積體電路112之充電電流I2便開始下降至充電電流I2低於電流門檻值後，例如時間T4後，該對應之充電積體電路112便停止運作，此時電池單元12所接收之電流便改為等於充電電流I1，例如等於0.6C。當時間在T5時，電池單元12的電壓已上升至等於充電積體電路111所對應的電壓門檻值，故充電積體電路111之控制單元21便控制充電積體電路111改執行定電壓模式而輸出充電電壓V1，此時充電積體電路111所輸出之充電電流I1將開始下降。然後當到達時間T6時，充電積體電路111之充電電流I1便開始下降至充電電流I1低於電流門檻值後，例如時間T6後，該對應之充電積體電路111便停止運作，而在時間T6後，由於所有的充電積體電路111、112、113皆停止運作，即代表電池單元12已充電完畢，故充電裝置10便停止運作而結束充電 。 The operation mode and principle of the charging device 10 of the present invention will be exemplarily described below with reference to FIG. 3, and in order to better understand the technology of the present invention, FIG. 3 indicates V1, V2, and V3 to represent the charging integrated circuits 111 and 112, respectively. The charging voltage outputted by 113, and I1, I2, and I3 are respectively indicated to represent the charging currents outputted by the charging integrated circuits 111, 112, and 113, and the third figure is the voltage threshold corresponding to each charging integrated circuit. The values are exemplified by the voltage threshold corresponding to the other charging integrated circuits. Please refer to FIG. 3 in conjunction with FIGS. 1 and 2, wherein FIG. 3 is a timing diagram of the voltage and current of the charging device shown in FIG. 1 when the battery unit is charged. As shown in FIG. 3, when the charging device 10 is not operated before time T0, the charging voltage of the charging integrated circuit 111 can be set to V1, for example, 4.2 V, and the charging voltage of the charging integrated circuit 112 is set to V2 in advance. For example, 4.1 V, the charging voltage of the charging integrated circuit 113 is preset to be V3, for example, 4.0V. After the time T0, the charging device 10 starts to operate, and the control units 21, 22, 23 respectively control the charging integrated circuits 111, 112, 113 to perform the constant current mode and output the charging currents I1, I2 and I3 of a fixed value, To the battery bill The element 12 is charged, at which time the current received by the battery unit 12 is equal to the sum of the charging currents I1, I2, I3 (I1 + I2 + I3), for example equal to 1.2 C (C is the capacity of the battery unit 12). At time T1, the voltage of the battery unit 12 has risen to be equal to the voltage threshold corresponding to the charging integrated circuit 113, so that the control unit 23 of the charging integrated circuit 113 controls the charging integrated circuit 113 to perform the constant voltage mode. The charging voltage V3 is output, and at this time, the charging current I3 outputted by the charging integrated circuit 113 starts to drop. Then, after the time T2 is reached, the charging current I3 of the charging integrated circuit 113 falls below the current threshold, the corresponding charging integrated circuit 113 stops operating, and the current received by the battery unit 12 is equal to the charging. The sum of the currents I1, I2 (I1 + I2) is, for example, equal to 1.0C. When the voltage of the battery unit 12 has risen to be equal to the voltage threshold corresponding to the charging integrated circuit 112 at time T3, the control unit 22 of the charging integrated circuit 112 controls the charging integrated circuit 112 to perform the constant voltage mode. The charging voltage V2 is output, and at this time, the charging current I2 outputted by the charging integrated circuit 112 starts to drop. Then, when the time T4 is reached, the charging current I2 of the charging integrated circuit 112 starts to drop until the charging current I2 is lower than the current threshold. For example, after the time T4, the corresponding charging integrated circuit 112 stops operating. The current received by unit 12 is then changed to equal the charging current I1, for example equal to 0.6C. When the time is T5, the voltage of the battery unit 12 has risen to be equal to the voltage threshold corresponding to the charging integrated circuit 111, so the control unit 21 of the charging integrated circuit 111 controls the charging integrated circuit 111 to perform the constant voltage mode. The charging voltage V1 is output, and at this time, the charging current I1 output from the charging integrated circuit 111 starts to drop. Then, when the time T6 is reached, the charging current I1 of the charging integrated circuit 111 starts to drop until the charging current I1 is lower than the current threshold. For example, after the time T6, the corresponding charging integrated circuit 111 stops operating, and at the time. After T6, since all of the charging integrated circuits 111, 112, and 113 are stopped, that is, the battery unit 12 has been charged, the charging device 10 stops operating and ends charging. .
於一些實施例中，電池單元12可由鋰電池所構成，但不以此為限，舉凡各種可進行充電之電池皆可構成電池單元12。 In some embodiments, the battery unit 12 can be constructed of a lithium battery, but not limited thereto, and the battery unit 12 can be constructed by various batteries that can be charged.
於一些實施例中，如第1圖所示，複數個充電積體電路111、112、113更可分別具有一第一保護電路31、32、33，複數個第一保護電路31、32、33分別用以保護對應之充電積體電路111、112、113之內部電路，以防止有過電壓及/或過電流的情況發生。 In some embodiments, as shown in FIG. 1, the plurality of charging integrated circuits 111, 112, 113 may further have a first protection circuit 31, 32, 33, and a plurality of first protection circuits 31, 32, 33, respectively. They are used to protect the internal circuits of the corresponding charging integrated circuits 111, 112, 113, respectively, to prevent overvoltage and/or overcurrent.
另於其它實施例中，如第1圖所示，充電裝置10更具有複數個第二保護電路41、42、43，其中每一第二保護電路係電連接於對應之充電積體電路之輸出端與電池單元12之間，且可由二極體所構成，但不以此為限，亦可由金屬氧化物半導體場效電晶體(MOSFET)所構成，每一第二保護電路用以防止一逆向電流由電池單元12流入對應之充電積體電路中。 In other embodiments, as shown in FIG. 1, the charging device 10 further has a plurality of second protection circuits 41, 42, 43, wherein each of the second protection circuits is electrically connected to the output of the corresponding charging integrated circuit. Between the terminal and the battery unit 12, and may be composed of a diode, but not limited thereto, or a metal oxide semiconductor field effect transistor (MOSFET), each of the second protection circuits is used to prevent a reverse The current flows from the battery unit 12 into the corresponding charging integrated circuit.
綜上所述，本案提供一種充電方法及其適用之充電裝置，其中本案之充電裝置係藉由複數個充電積體電路來提供電池單元充電所需之電能，故可快速對電池單元進行充電，而每一充電積體電路亦可選用耐電流等級較低的電子元件來構成，故節省了生產成本。此外，由於本案之每一充電積體電路在執行定電壓模式時係輸出電壓值與其它充電積體電路所輸出之充電電壓的電壓值相異的充電電壓，並當任一充電積體電路在執行定電壓模式且自身所輸出之充電電流下降至低於電流門檻值時，自動控制對應的充電積體電路停止運作，故本案之充電裝置並無須如前述第一種傳統充電裝置具有設置用來偵測電壓之偵測電路，亦無需如前述第二種 傳統的充電裝置還需設置中央處理單元及模式切換電路等，故本案之充電裝置之生產成本更為減少。 In summary, the present invention provides a charging method and a charging device therefor, wherein the charging device of the present invention provides power required for charging the battery unit by a plurality of charging integrated circuits, so that the battery unit can be quickly charged. Each charging integrated circuit can also be formed by using electronic components with low current resistance level, thereby saving production costs. In addition, since each charging integrated circuit of the present case performs a constant voltage mode, the output voltage value is different from the charging voltage of the charging voltage output by the other charging integrated circuit, and when any charging integrated circuit is in When the constant voltage mode is executed and the charging current output by itself drops below the current threshold, the corresponding charging integrated circuit is automatically controlled to stop operating. Therefore, the charging device of the present invention does not have to be set as in the first conventional charging device. The detection circuit for detecting voltage does not need to be the second one as described above. The conventional charging device also needs to be provided with a central processing unit and a mode switching circuit, so that the production cost of the charging device of the present invention is further reduced.
是以本案之充電方法及其適用之充電裝置極具產業之價值，爰依法提出申請。 The charging method of this case and its applicable charging device are of great industrial value, and the application is made according to law.
本案得由熟習此技術之人士任施匠思而為諸般修飾，然皆不脫如附申請專利範圍所欲保護者。 This case has been modified by people who are familiar with the technology, but it is not intended to be protected by the scope of the patent application.
