短路元件、具有異常保護功能的短路元件、相關之電路以及二次電池包 Short circuit component, short circuit component with abnormal protection function, related circuit and secondary battery pack

本創作是有關於一種短路元件，其藉由物理性地與電氣性的連接，使原本斷路或開路的兩導電電極短路或電氣連接。 The present invention relates to a short-circuiting element that is short-circuited or electrically connected to two electrically conductive electrodes that are otherwise open or open by a physical and electrical connection.

先前如台灣專利證書編號：TW I443701所提到的一種電池包1，如圖17所繪示該電池包1之電路構成圖，在串聯有複數個電池單元的電池10之保護電路，僅在充放電路徑上設有保護元件30，若電池10之一部分電池單元產生異常使保護元件30動作，電池10中的充放電路徑被熔斷，電池10就無法持續提供電力，雖可以保護電池10的安全，但因一部分的電池單元12異常，就使整個電池10失效，如此無形中使電池10的成本無法降低或維修成本增高。尤其近來許多電子產品、電動機車、電動腳踏車以及電動汽車需求更大的電力或電流，目前的技術大都藉用將許多個電池單元串並聯來達成高電壓與大電流或大電力的需求，運用先前的技術，其結果是若有任一電池單元12出現異常，許多個其他正常的電池單元11、13、14就無法繼續使用，實在是一種資源的浪費。 A battery pack 1 as previously mentioned in Taiwan Patent Certificate No. TW I443701, as shown in FIG. 17, is a circuit diagram of the battery pack 1, and a protection circuit for the battery 10 having a plurality of battery cells connected in series is only charged. The protection element 30 is disposed on the discharge path. If a part of the battery unit of the battery 10 is abnormal and the protection element 30 is operated, the charge and discharge path in the battery 10 is blown, and the battery 10 cannot continuously supply power, and although the safety of the battery 10 can be protected, However, since a part of the battery unit 12 is abnormal, the entire battery 10 is disabled, so that the cost of the battery 10 cannot be reduced or the maintenance cost is increased. Especially in recent years, many electronic products, electric motors, electric bicycles, and electric vehicles require more power or current. Most of the current technologies borrow a large number of battery cells in series and parallel to achieve high voltage and high current or large power demand. The result is that if any of the battery cells 12 is abnormal, many other normal battery cells 11, 13, 14 cannot be used any more, which is a waste of resources.

另，先前如台灣專利公開編號：TW 201528471 A所提到的一種應用短路元件的電池電路的電路圖，如圖示15所示，包含一短 路元件50與一保護元件57，在多個電池單元串並聯的電池組中，藉由短路元件50與保護元件57兩種元件，達到排除異常電池單元且保護正常的電池單元持續運作。但使用兩個元件不僅增加元件的使用數量與電路板的面積，同時增加零件成本與庫存管理的複雜度等多項缺點。 In addition, a circuit diagram of a battery circuit using a short-circuiting element as previously mentioned in Taiwan Patent Publication No. TW 201528471 A, as shown in FIG. 15, includes a short The circuit component 50 and the protection component 57, in the battery pack in which the plurality of battery cells are connected in series, and the two components of the short circuit component 50 and the protection component 57, can achieve continuous operation of the battery cell that excludes the abnormal battery cell and protects the normal. However, the use of two components not only increases the number of components used and the area of the board, but also increases the cost of parts and the complexity of inventory management.

針對上述之缺點的改善，本創作提供一種短路元件，該短路元件可以利用通過短路元件的電流，進而產生熱能，使短路元件中原本斷路(open)的線路或電極導通，產生旁通路徑，特別值得一提的是短路元件的結構中，因可熔導體與內電極之間有一通道，且有高低差，所以熔融的可熔導體可以快速地使二內電極短路。另，本創作提供一種具有異常保護功能的短路元件，將先前技術中之保護元件與短路元件兩種元件合併成單一元件，使用此具有異常保護功能的短路元件可以達到在多串並聯二次電池包的應用電路中，將發生異常的電池單元切斷其充放電路徑，利用旁通路徑，將充放電路徑引導至正常的電池單元，使二次電池包不會因其中一電池單元異常，其他正常的電池單元就無法使用，如此可以節省許多電池材料的浪費，且可確保二次電池包的持續供電。 In view of the above-mentioned shortcomings, the present invention provides a short-circuiting component that can utilize the current through the short-circuiting component to generate thermal energy, thereby turning on the originally open circuit or electrode in the short-circuiting component, creating a bypass path, in particular It is worth mentioning that in the structure of the short-circuiting element, since there is a passage between the fusible conductor and the inner electrode and there is a difference in height, the molten fusible conductor can quickly short-circuit the two inner electrodes. In addition, the present invention provides a short-circuiting element having an abnormal protection function, which combines two components of the prior art protection element and the short-circuiting component into a single component, and the short-circuiting component having the abnormal protection function can be used in a multi-string parallel secondary battery. In the application circuit of the package, the battery unit in which the abnormality occurs is cut off from the charging and discharging path, and the bypass path is used to guide the charging and discharging path to the normal battery unit, so that the secondary battery pack is not abnormal due to one of the battery units, and the like. A normal battery unit cannot be used, which saves a lot of battery material waste and ensures continuous power supply to the secondary battery pack.

圖11為使用短路元件100之電路圖。圖1本創作實施例之一種短路元件100的等效電路圖，其動作說明如下：短路元件100的等效電路圖包含由第一內電極131、第二內電極132以及可熔導體170所組成的短路開關S，該短路開關S經由第一外接電極141與第二外接電極142串聯於第一外部電路1a、第二外部電路1b之間；以及熱產生元件188，該熱產生元件188經由第三外接電極143與第四外接電極144串聯於電源元件4c與開關元件6c之間。該開關元件6c的初始狀態為斷路或開路，直到有需求將原本兩彼此斷路的第一外部電路1a、第二外部電路1b導通時，檢測電路5c輸出一信號給開關元件6c，該開關元件6c才會導通或短路，使電流流經熱產生元件188，進而使熱產生元件188發熱，並將可熔導體170熔融，該熔融的可熔導體170使第一內電極131與第二內電極132彼此短路(物理連接與電氣連接)，進而使原本兩彼此斷路的第一外部電路1a、第二外部電路1b導通。需說明的是藉由控制檢測電路5c輸出信號的時間可以控制熱產生元件188發熱的時間或電流通過熱產生元件188的時間。請參閱圖1D，圖1D為可熔導體被熔融使第一內電極131與第二內電極132短路的示意圖，當熱產生元件188發熱時，助熔材 料190會先液化且濕潤性(Wetting)第一內電極131與第二內電極132的表面提升其吸附力，然後可熔導體170熔融，因蓄熱電極125與內電極130之間有高低差，所以熔融的可熔導體170很容易順著通道20流入第一內電極131與第二內電極132之間的間隙D，且使兩者短路或導通。 FIG. 11 is a circuit diagram of the use of the short-circuiting element 100. 1 is an equivalent circuit diagram of a short-circuiting component 100 of the present embodiment, the operation of which is as follows: The equivalent circuit diagram of the short-circuiting component 100 includes a short circuit composed of the first inner electrode 131, the second inner electrode 132, and the fusible conductor 170. a switch S, the short circuit switch S is connected in series between the first external circuit 1a and the second external circuit 1b via the first external electrode 141 and the second external electrode 142; and a heat generating element 188 via the third external connection The electrode 143 and the fourth external electrode 144 are connected in series between the power supply element 4c and the switching element 6c. The initial state of the switching element 6c is an open circuit or an open circuit, and when it is required to turn on the first external circuit 1a and the second external circuit 1b which are originally disconnected from each other, the detecting circuit 5c outputs a signal to the switching element 6c, the switching element 6c The conduction or short circuit is caused to cause a current to flow through the heat generating element 188, thereby heating the heat generating element 188, and melting the fusible conductor 170, the molten soluble conductor 170 making the first inner electrode 131 and the second inner electrode 132 Short-circuiting (physical connection and electrical connection) with each other causes the first external circuit 1a and the second external circuit 1b, which are originally disconnected from each other, to be electrically connected. It should be noted that the time during which the heat generating element 188 generates heat or the time during which the current passes through the heat generating element 188 can be controlled by controlling the time at which the detecting circuit 5c outputs a signal. Referring to FIG. 1D, FIG. 1D is a schematic diagram of the fusible conductor being melted to short the first inner electrode 131 and the second inner electrode 132. When the heat generating element 188 is heated, the fluxing material is used. The material 190 first liquefies and wets the surface of the first inner electrode 131 and the second inner electrode 132 to increase its adsorption force, and then the fusible conductor 170 is melted, because of the height difference between the heat storage electrode 125 and the inner electrode 130. Therefore, the molten fusible conductor 170 easily flows into the gap D between the first inner electrode 131 and the second inner electrode 132 along the channel 20, and shorts or conducts both.

And electrically connecting the heat storage electrode 125d and the fourth upper electrode 124d, a channel 20d is formed between the soluble conductor 170d and the internal electrode 130d; when the heat generating element 188d generates heat, the meltable conductor 170d is melted, and the molten fusible The conductor 170d electrically connects the first inner electrode 131d and the second inner electrode 132d to each other via the channel 20d and disconnects the electricity between the heat storage electrode 125d and the fourth upper electrode 124d.

請參閱圖15，當電源電路4f的輸出電流I1發生過電流事件時，可熔導體171g會熔斷，達到過電流保護的功能；當第一外部電路1a發生異常時，切換信號電路5f會輸出一信號給開關電路6f，該開關電路6f才會導通或短路，使電流流經熱產生元件188g，進而使熱產生元件188g發熱，並將第二可熔導體172g熔融，該熔融的第二可熔導體172g使第一內電極131g與第二內電極132g彼此短路(物理連接與電氣連接)，因第一可熔導體171g的體積大於第二可熔導體172g的體積，所以在第二可熔導體172g熔融且使第一內電極131g與第二內電極132g彼此短路之後，才會熔斷第一可熔導體171g，該第一可熔導體171g熔斷後，電流就無法流經熱產生元件188g，因此熱產生元件188g停止發熱。因第一可熔導體171g熔斷後，電源電路4f的電流I1就無法供應給異常的第一外部電路1a，確保第一外部電路1a的安全，又，因短路開關S短路或導通，所以電源電路4f的電流路徑就經由短路開關S切換至第二外部電路1b，完成異常保護與切換電路的功能。 Please refer to FIG. 15, the power supply circuit when the output current I 1 4f overcurrent event, will blow the fusible conductor 171g, to achieve over-current protection function; 1a when the first external circuit abnormality occurs, the switching signal output circuit will 5f A signal is applied to the switching circuit 6f, and the switching circuit 6f is turned on or short-circuited, causing a current to flow through the heat generating element 188g, thereby causing the heat generating element 188g to generate heat, and melting the second meltable conductor 172g, the second meltable The fuse conductor 172g shorts (physically and electrically connects) the first inner electrode 131g and the second inner electrode 132g to each other, since the volume of the first fusible conductor 171g is larger than the volume of the second fusible conductor 172g, so the second fusible After the conductor 172g is melted and the first inner electrode 131g and the second inner electrode 132g are short-circuited to each other, the first fusible conductor 171g is melted, and after the first fusible conductor 171g is blown, the current cannot flow through the heat generating element 188g.

【電池包的保護動作與切換動作說明】 [Battery pack protection action and switching action description]

針對二次電池包588的保護動作與切換動作說明如下：詳細來 說，圖10是該二次電池包588正常時的電路圖，當充電電流與放電電流都正常時，且二個電池元件組4a與4b的電壓與溫度亦正常時，二個具有異常保護功能的短路元件100g、100g1都不會動作，二個開關電路6a、6b都維持在斷路(off)狀態，二個具有異常保護功能的短路元件100g、100g1的短路開關S亦維持在斷路(off)狀態。若外接是充電裝置1，且電池元件組4a、4b的電壓低於某一數值以下，則充放電控制電路2切換電流方向開關I，輸入充電電流Ic，充電電流Ic會如圖1所示沿充電電流路徑Ic對二個電池元件組4a與4b充電。若電池元件組4a、4b的電壓高於某一數值以上，則斷開電流方向開關I，停止輸入充電電流Ic。若外接是電子裝置1且依據偵測控制電路5a、5b測得電壓在某個數值範圍內，則充放電控制電路2切換電流方向開關I，輸出放電電流Id，對電子裝置1放電，放電電流會如圖1所示沿放電電流路徑Id對電子裝置1放電。若電池元件組4a、4b的電壓低於某一數值以下，則斷開電流方向開關I，停止輸出放電電流Id。 The protection operation and the switching operation of the secondary battery pack 588 are explained as follows: In detail, FIG. 10 is a circuit diagram of the secondary battery pack 588 in a normal state, when both the charging current and the discharging current are normal, and the two battery element groups 4a When the voltage and temperature of 4b are also normal, the two short-circuiting elements 100g and 100g1 with abnormal protection functions will not operate, and the two switching circuits 6a and 6b are maintained in an off state, and two have abnormal protection functions. The short-circuiting switches S of the short-circuiting elements 100g and 100g1 are also maintained in an off state. When the external charging device 1, and the voltage of the battery element groups 4a, 4b is less than a certain value or less, the charge and discharge current of second switching direction of the switch control circuit I, the input charging current I c, the charging current I c in FIG. 1 will illustrates charging current path along two I c of the battery charging element groups 4a and 4b. If the voltage of the battery element groups 4a, 4b is higher than a certain value, the off-current direction switch I, stop input charging current I c. If the external is an electronic device 1 according to the detecting and control circuits 5a, 5b measured voltage is within a certain range of values, the charging and discharging control circuit 2 switches the direction switching current I, output discharge current I d, 1 electron discharge device, the discharge 1 along the path shown by the discharge current I d of FIG currents discharging the electronic device. If the voltage of the battery element groups 4a, 4b is less than a certain value or less, the off-current direction switch I, stops the output of the discharge current I d.

圖10A繪示當電池元件組4a出現異常，如：過充或過電壓或過溫時的電路圖，此時外接裝置是充電裝置1，當該偵測控制電路5a偵測到電池元件組4a的電壓或溫度超過正常值時，偵測控制電路5a會傳送一信號給開關電路6a，該開關電路6a會切換至導通(on)狀態，此時就有電流流過熱產生元件188g，該過熱產生元件188g會發熱，切斷第一可熔導體171g的充電電流路徑Ic，且使短路開關S從斷路或開路狀態切換至導通或短路狀態，使充放電電流路徑Ic、Id切換至具有異常保護功能的短路元件100g1，而不會流經電池元件組4a，如此確保電池元件組4a不會過充產生危險。當然，若所有的電池元件組4a、4b都出現異 常現象(如：過充或過溫)，該二次電池包588就失去提供電力或充放電的功能。 FIG. 10A is a circuit diagram showing an abnormality in the battery element group 4a, such as overcharge or overvoltage or overtemperature, when the external device is the charging device 1, and when the detection control circuit 5a detects the battery component group 4a. When the voltage or temperature exceeds the normal value, the detection control circuit 5a transmits a signal to the switch circuit 6a, and the switch circuit 6a is switched to the on state. At this time, the current flows through the heat generating element 188g, and the overheat generating element 188g generates heat, cuts off the charging current path I c of the first fusible conductor 171g, and switches the short-circuiting switch S from the open or open state to the conducting or short-circuiting state, and switches the charging and discharging current paths I c and I d to have abnormalities. The short-circuiting element 100g1 of the protective function does not flow through the battery element group 4a, thus ensuring that the battery element group 4a does not overcharge. Of course, if all of the battery element groups 4a, 4b are abnormal (such as overcharge or overtemperature), the secondary battery pack 588 loses the function of providing power or charging and discharging.

圖10B繪示當電池元件組4b出現異常，如：過充或過電壓或過溫時的電路圖，此時外接裝置是充電裝置1，當該偵測控制電路5b偵測到電池元件組4b的電壓或溫度超過正常值時，偵測控制電路5b會傳送一信號給開關電路6b，該開關電路6b會切換至導通(on)狀態，此時就有電流流過熱產生元件188g，該熱產生元件188g會發熱，切斷第一可熔導體171g的充電電流路徑Ic，且使短路開關S從斷路或開路狀態切換至導通或短路狀態，使充放電電流路徑Ic、Id切換至充放電控制電路2，而不會流經電池元件組4b。如此確保電池元件組4b不會一直維持在過充或過電壓的危險，同時可讓正常的電池元件組4a繼續提供充放電的功能或維持二次電池包588持續提供電力的功能。當然，若所有的電池元件組4a、4b都出現異常現象(如：過充或過溫)，該二次電池包588就失去提供電力或充放電的功能。 FIG. 10B is a circuit diagram showing an abnormality in the battery element group 4b, such as overcharge or overvoltage or overtemperature. At this time, the external device is the charging device 1, and when the detection control circuit 5b detects the battery component group 4b. When the voltage or temperature exceeds the normal value, the detection control circuit 5b transmits a signal to the switch circuit 6b, and the switch circuit 6b is switched to the on state. At this time, the current flows through the heat generating element 188g, and the heat generating element 188g will generate heat, cut off the charging current path I c of the first fusible conductor 171g, and switch the short-circuiting switch S from the open or open state to the conducting or short-circuit state, and switch the charging and discharging current paths I c and I d to the charging and discharging. The circuit 2 is controlled so as not to flow through the battery element group 4b. This ensures that the battery element group 4b does not always maintain the risk of overcharging or overvoltage, while allowing the normal battery element group 4a to continue to provide the function of charging and discharging or to maintain the function of the secondary battery pack 588 to continuously supply power. Of course, if all of the battery element groups 4a, 4b are abnormal (such as overcharge or overtemperature), the secondary battery pack 588 loses the function of providing power or charging and discharging.

另，當充電電流的電流值高於第一可熔導體171g的額定電流值，或放電電流值高於第一可熔導體171g的額定電流值時，造成此異常的原因有如：正極P與負極N之間短路或充電裝置輸出異常的電流，此時電池元件組4a、4b的電壓或溫度都在正常範圍，所以偵測控制電路5a、5b不會送出信號給開關電路6a、6b，因此開關電路6a、6b維持在斷路(off)的狀態，所以沒有電流可以通過熱產生元件188g，該熱產生元件188g也不會發熱，因此短路開關S維持在斷路(off)的狀態，但二個第一可熔導體171g中的任一個會因充電電流的電流值高於第一可 熔導體171g的額定電流值，或放電電流值高於第一可熔導體171g的額定電流值而斷開充放電路徑Ic、Id，因此電池元件組4a、4b無法被充電或放電，因此電池元件組4a、4b不會被大的充放電電流造成損壞或危險，達到過電流保護的功能與保護二次電池包588的安全。 In addition, when the current value of the charging current is higher than the rated current value of the first fusible conductor 171g, or the discharging current value is higher than the rated current value of the first fusible conductor 171g, the cause of the abnormality is as follows: the positive electrode P and the negative electrode The short circuit between N or the charging device outputs an abnormal current. At this time, the voltage or temperature of the battery element group 4a, 4b is in the normal range, so the detection control circuits 5a, 5b do not send signals to the switch circuits 6a, 6b, so the switch The circuits 6a and 6b are maintained in an off state, so that no current can pass through the heat generating element 188g, and the heat generating element 188g does not generate heat, so that the shorting switch S is maintained in an off state, but two Any one of the fusible conductors 171g may be turned off and discharged due to the current value of the charging current being higher than the rated current value of the first fusible conductor 171g, or the discharging current value being higher than the rated current value of the first fusible conductor 171g.
