Abstract:
(EN) Provided are a battery cover assembly, a single-cell battery, a battery module, a power battery pack, and an electric vehicle. The battery cover assembly comprises a cover (104), an electrode internal terminal (101) and an electrode external terminal (110). The electrode internal terminal (101) and the electrode external terminal (110) are electrically connected by means of a current interruption structure (100) installed at the cover (104). The current interruption structure (100) has a sealed cavity (103) filled with a gas-producing medium. The sealed cavity (103) is configured such that the gas-producing medium is electrically connected to positive and negative electrodes of a battery, respectively. If a voltage difference between the positive and negative electrodes of the battery exceeds a rated value, the medium can produce a gas, and pressure of the gas causes an interruption of an electrical connection between the electrode internal terminal (101) and an electrode external terminal (110).
(FR) L'invention concerne un ensemble couvercle de batterie, une batterie unicellulaire, un module de batterie, un bloc-batterie d'alimentation et un véhicule électrique. L'ensemble couvercle de batterie comprend un couvercle (104), une borne interne d'électrode (101) et une borne externe d'électrode (110). La borne interne d'électrode (101) et la borne externe d'électrode (110) sont connectées électriquement au moyen d'une structure d'interruption de courant (100) installée au niveau du couvercle (104). La structure d'interruption de courant (100) a une cavité étanche (103) remplie d'un milieu de production de gaz. La cavité étanche (103) est configurée de telle sorte que le milieu de production de gaz est électriquement connecté à des électrodes positive et négative d'une batterie, respectivement. Si une différence de tension entre les électrodes positive et négative de la batterie dépasse une valeur nominale, le milieu peut produire un gaz, et la pression du gaz provoque une interruption d'une connexion électrique entre la borne interne d'électrode (101) et une borne externe d'électrode (110).
(ZH) 一种电池盖板组件、单体电池、电池模组、动力电池包和电动汽车,该电池盖板组件包括盖板(104)、电极内端子(101)和电极外端子(110),电极内端子(101)与电极外端子(110)之间通过安装在盖板(104)上的电流中断结构(100)电连接,电流中断结构(100)具有填充有能够产生气体的介质的密封腔(103),密封腔(103)构造为使得能够产生气体的介质分别与电池正负极电连接,并且在电池正负极之间的电压差超过额定值时,介质能够产生气体,以在该气体的气压作用下断开电极内端子(101)和电极外端子(110)之间的电连接。
