Title
(EN) CELL LEAD-OUT PIECE, BATTERY, AND ELECTRIC VEHICLE
(FR) PIÈCE DE SORTIE DE CELLULE, BATTERIE ET VÉHICULE ÉLECTRIQUE
(ZH) 电芯引出片、电池及电动汽车
Abstract
(EN) A cell lead-out piece (10), a battery, and an electric vehicle. The cell lead-out piece (10) comprises a thermally conductive member (13), a body portion (11), and two extension branches (12) extending from one end of the body portion (11) in a bent manner; the body portion (11) is used for electrically connecting to positive and negative electrode poles (40) of the battery; the two extension branches (12) are respectively used for electrically connecting to tabs (21) of an electrode core (20) in the battery; the two extension branches (12) are spaced apart from each other to form a mounting gap (14); the thermally conductive member (13) is provided at the side of the two extension branches (12) facing away from the electrode core (20); the thermally conductive member (13) at least partially covers the mounting gap (14).
(FR) L'invention concerne une pièce de sortie de cellule (10), une batterie et un véhicule électrique. La pièce de sortie de cellule (10) comprend un élément thermoconducteur (13), une partie corps (11), et deux branches d'extension (12) s'étendant à partir d'une extrémité de la partie corps (11) de manière courbée ; la partie corps (11) est utilisée pour la connexion électrique à des pôles d'électrode positive et négative (40) de la batterie ; les deux branches d'extension (12) sont respectivement utilisées pour la connexion électrique à des pattes (21) d'un noyau d'électrode (20) dans la batterie ; les deux branches d'extension (12) sont espacées l'une de l'autre pour former un espace de montage (14) ; l'élément thermoconducteur (13) est disposé sur le côté des deux branches d'extension (12) faisant face au noyau d'électrode (20) ; l'élément thermoconducteur (13) recouvre au moins partiellement l'espace de montage (14).
(ZH) 一种电芯引出片(10)、电池及电动汽车,该电芯引出片(10)包括导热件(13)、主体部(11)和从主体部(11)的一端弯折延伸的两个延伸枝节(12),主体部(11)用于电连接电池的正负极极柱(40),两个延伸枝节(12)分别用于与电池中极芯(20)的极耳(21)电连接,两个延伸枝节(12)间隔设置形成安装空隙(14),导热件(13)设置在两个延伸枝节(12)背离极芯(20)的一侧,导热件(13)至少部分覆盖安装空隙(14)。
