Abstract

The present invention proposes a protection element comprising: plural input-output ends including the first input-output end, the second input-output end, and the third input-output end; plural overcurrent protection elements including the first overcurrent protection element and the second overcurrent protection element; and a heat-generating component. The first overcurrent protection element and the second overcurrent protection element are applied between the first input-output end and the second input-output end of the protection element for providing the first bidirectional current path. When the current between the first input-output end and the second input-output end is not normal, the current path of the second overcurrent protection element is switched-off. When the heat-generating component heats up, the current path of the first overcurrent protection element is firstly switched-off, but the current path between the second input-output end and the third input-output end is still maintained at the conduction state. After a period of time, the current path of the second overcurrent protection element is switched-off.

保護元件與二次電池包 Protective component and secondary battery pack

本發明提出一種保護元件與二次電池包,特別是應用於行動電子產品中有高充電電流或高放電電流規格需求的保護元件或二次電池包,本發明的保護元件,具有斷開高充電電流路徑或高放電電流路徑的保護功能。 The invention provides a protection element and a secondary battery package, in particular to a protection element or a secondary battery package having a high charging current or a high discharge current specification requirement in a mobile electronic product, and the protection element of the invention has a disconnection high charging Protection function for current path or high discharge current path.

目前已知可防止過電流與過電壓的保護元件,且應用於攜帶式電子裝置如移動式電話或筆記型電腦或平板電腦之二次電池的保護線路(如專利文獻1),該些保護元件都具有單一或相同額定電流的過電流保護規格或相同的充放電電流路徑,大部分是在絕緣基板上配置一發熱體以及一低熔點金屬體,藉由低熔點金屬體形成等效的二個保險絲(可熔金屬體)元件,當過電流事件發生時,低熔點金屬體(保險絲元件)因自己本身發熱而熔斷,但無法確定等效的二個保險絲元件中哪一個會斷開,另外,當過電壓事件發生時,發熱體發熱熔斷低熔點金屬體,藉此達到過電壓與過電流的保護,但同樣的無法確定二個保險絲元件中哪一個會先斷開,且無提供一放電電流路徑或一段時間的放電電流路徑,降低已發生過電壓裝置的電壓。 A protection circuit for preventing overcurrent and overvoltage is known, and is applied to a protection circuit of a secondary battery of a portable electronic device such as a mobile phone or a notebook computer or a tablet computer (for example, Patent Document 1). The overcurrent protection specifications or the same charge and discharge current paths all have a single or the same rated current, and most of them are a heating element and a low melting point metal body disposed on the insulating substrate, and the equivalent two are formed by the low melting point metal body. a fuse (fusible metal body) component, when an overcurrent event occurs, the low melting point metal body (fuse element) is blown by itself, but it is impossible to determine which of the equivalent two fuse elements is disconnected. When an overvoltage event occurs, the heating element fuses the low melting point metal body to thereby protect the overvoltage and overcurrent, but it is impossible to determine which of the two fuse elements will be disconnected first, and no discharge current is provided. The path or the discharge current path for a period of time reduces the voltage at which the overvoltage device has occurred.

又,另一種未使用保險絲元件而以彈性構件來取代的保護元件(如專利文獻2),其缺點是一樣的,當過電壓事件發生時,無法確定二 個彈性構件中哪一個會先斷開,且無提供一放電電流路徑或一段時間的放電電流路徑,降低過電壓裝置的電壓。 Further, another protective element (such as Patent Document 2) that is replaced with an elastic member without using a fuse element has the same disadvantages, and when an overvoltage event occurs, it is impossible to determine two. Which of the elastic members is disconnected first, and does not provide a discharge current path or a discharge current path for a period of time, reducing the voltage of the overvoltage device.

特別是目前對保護元件所需額定電流值的規格愈來愈高,例如應用於電動自行車、電動工具、電動汽車等鋰離子二次電池,如此低熔點金屬體的體積或厚度變得愈來愈大或愈厚,當發熱體發熱要熔斷低熔點金屬體所需的熱能須更大或熔斷的時間變更長,就算保護元件可以斷開充電電流的路徑,但卻無法解決反應時間過長與電路中某些裝置存在過電壓的事實。 In particular, the current specifications for the rated current required for the protection component are becoming higher and higher, for example, for lithium ion secondary batteries such as electric bicycles, electric tools, electric vehicles, etc., so that the volume or thickness of the low melting point metal body becomes more and more Large or thicker, when the heating element is heated, the heat energy required to melt the low-melting metal body needs to be larger or the time of melting changes longer. Even if the protective element can disconnect the charging current path, it cannot solve the reaction time and the circuit. The fact that some devices have overvoltages.

【保護元件888a與889a的動作說明】 [Description of Actions of Protection Elements 888a and 889a]

保護元件888a與889a的動作特徵如下說明:第一實施例的保護元件888a,當該第一輸入輸出端I/O1與該第二輸入輸出端I/O2之間的電流異常時,第二過電流保護元件8的電流路徑被斷開。請參考圖2H,第二實施例的保護元件889a,當該第一端電極11與該第二端電極21之間的電流異常時,可熔導體8被自身發熱所熔斷,其電流路徑被斷開。第一實施例的保護元件888a,當電流通過熱產生組件7而發熱時,第一 過電流保護元件S的電流路徑先被斷開,但該第二輸入輸出端I/O2至該第三輸入出端O3之間的電流路徑仍維持在導通狀態,一段時間之後,第二過電流保護元件8的電流路徑才被斷開。請參考圖2I,第二實施例的保護元件889a,當電流通過熱產生組件7而發熱時並將熱能傳導至集熱電極15,部分焊料9(1)被集熱電極15上的熱能所熔融,彈性構件S藉由本身的彈性強制脫離集熱電極15,使集熱電極15與彈性構件S之間由短路(short circuit)狀態轉變至開路(open circuit)狀態,致使集熱電極15與彈性構件S之間的電流路徑先被斷開,但該第二端電極21至該第三端電極31之間的電流路徑仍維持在導通狀態,一段時間之後,可熔導體8被集熱電極15上的熱能所熔斷,致使第二端電極21至該第三端電極31的電流路徑才被斷開。需特別說明的是:因為要使第二端電極21至該第三端電極31的電流路徑被斷開,必須熔融焊料9(2)以及熔融部分的可熔導體8且將可熔導體8斷開成兩部分,兩者的厚度或體積都遠比只需熔融部分焊料9(1)的厚度或體積大的許多,所以這就是彈性構件S的電流路徑會比可熔導體8的電流路徑先斷開的原因。若可熔導體8的厚度或體積愈厚,則上述的一段時間會愈長,因此可以藉由設計不同可熔導體8的厚度或截面積,使上述一段時間可以被設定或控制。當然焊料9(1)與焊料9(2)也可使用不同熔點或液化點的焊料,達到彈性構件S的電流路徑會比可熔導體8的電流路徑先斷開的結果。這也是本發明保護元件的技術特徵與優點,特別是應用端所需的額定電流愈高時,因可熔導體8必須增大截面積或厚度或體積,這些會增加熱產生組件7熔斷可熔導體8的時間,但本發明藉由彈性構件S與焊料9(1)的組合,可以快速的斷開第一雙向的電流路徑,不會受到可熔導體8變厚或截面 積變大或體積變大的影響。另一技術特徵是當第一雙向的電流路徑被斷開後,藉由可熔導體被熔斷仍需一段時間,所以提供了第二端電極21至該第三端電極31之間電流路徑仍能維持導通一段時間或第二輸入出端至第三輸入出端之間電流路徑仍能維持導通一段時間。上述的第二過電流保護元件8的額定電流值高於10A,較佳的是高於20A,最佳的是高於30A。上述的第一過電流保護元件S的額定電流值比第二過電流保護元件8的額定電流值高百分之十以上。上述的【一段時間】大於30秒,較佳的是大於10分鐘,最佳的是大於20分鐘。 The action characteristics of the protection elements 888a and 889a are as follows: the protection element 888a of the first embodiment, when the current between the first input/output terminal I/O1 and the second input/output terminal I/O2 is abnormal, the second The current path of the current protection element 8 is broken. Referring to FIG. 2H, the protection element 889a of the second embodiment, when the current between the first terminal electrode 11 and the second terminal electrode 21 is abnormal, the fusible conductor 8 is blown by its own heat, and its current path is broken. open. The protective element 888a of the first embodiment, when the current is generated by the heat generating component 7, is first The current path of the overcurrent protection component S is first turned off, but the current path between the second input/output terminal I/O2 to the third input terminal O3 is maintained in a conducting state, and after a period of time, the second overcurrent The current path of the protection element 8 is then disconnected. Referring to FIG. 2I, the protection element 889a of the second embodiment, when the current is generated by the heat generating component 7, generates heat and conducts heat to the heat collecting electrode 15, and the portion of the solder 9(1) is melted by the heat energy on the heat collecting electrode 15. The elastic member S is forcibly decoupled from the heat collecting electrode 15 by its own elasticity, and the short circuit state is changed to the open circuit state between the heat collecting electrode 15 and the elastic member S, so that the heat collecting electrode 15 and the elastic state are caused. The current path between the members S is first turned off, but the current path between the second end electrode 21 and the third end electrode 31 is maintained in an on state, and after a while, the fusible conductor 8 is collected by the collector electrode 15. The thermal energy on the fuse is blown, so that the current path of the second terminal electrode 21 to the third terminal electrode 31 is broken. It should be particularly noted that since the current path of the second terminal electrode 21 to the third terminal electrode 31 is to be broken, the solder 9 (2) and the meltable conductor 8 of the molten portion must be melted and the meltable conductor 8 is broken. In two parts, the thickness or volume of both is much larger than the thickness or volume of the molten solder 9(1), so that the current path of the elastic member S is earlier than the current path of the fusible conductor 8. The reason for the disconnection. If the thickness or volume of the fusible conductor 8 is thicker, the above-mentioned period of time will be longer, so that the above-described period of time can be set or controlled by designing the thickness or cross-sectional area of the different fusible conductors 8. Of course, the solder 9(1) and the solder 9(2) may also use solders having different melting points or liquefaction points, as a result of the current path of the elastic member S being disconnected earlier than the current path of the fusible conductor 8. This is also a technical feature and advantage of the protective element of the present invention, in particular, the higher the rated current required at the application end, because the fusible conductor 8 must increase the cross-sectional area or thickness or volume, which will increase the heat generating component 7 to melt and melt. The time of the conductor 8, but the combination of the elastic member S and the solder 9(1) can quickly open the first bidirectional current path without being thickened or cross-section by the fusible conductor 8. The effect of large or large volume increases. Another technical feature is that after the first bidirectional current path is disconnected, it still takes a period of time for the fusible conductor to be blown, so that the current path between the second end electrode 21 and the third end electrode 31 can still be provided. The current path between the second input and the third input and output can be maintained for a period of time. The above-mentioned second overcurrent protection element 8 has a rated current value higher than 10 A, preferably higher than 20 A, and most preferably higher than 30 A. The rated current value of the first overcurrent protection element S described above is more than ten percent higher than the rated current value of the second overcurrent protection element 8. The above [period] is greater than 30 seconds, preferably greater than 10 minutes, and most preferably greater than 20 minutes.
