Title
(EN) Battery cell leading-out piece, battery and electric automobile
(ZH) 电芯引出片、电池及电动汽车
Abstract
(EN) The utility model discloses a battery cell leading-out piece, which comprises a heat conduction piece, a main body part and two extending branches which are bent and extend from one end of the main body part, the main body part is used for being electrically connected with a positive pole and a negative pole of a battery, the two extending branches are respectively used for being electrically connected with tabs of a pole core in the battery, and the two extending branches are arranged at intervals to form a mounting gap. The heat conduction piece is arranged on the sides, deviating from the pole core, of the two extension branches and covers the installation gap. According to the battery cell leading-out piece, the heat conduction piece is arranged in the installation gap between the twoextension branches, so that the heat dissipation area of the battery cell leading-out piece is increased and the heat dissipation performance of the battery cell leading-out piece is improved under the condition that the work of the battery cell leading-out piece is not influenced. The invention further provides a battery and an electric automobile.
(ZH) 本实用新型公开一种电芯引出片,包括导热件、主体部和从主体部的一端弯折延伸的两个延伸枝节,主体部用于电连接电池的正负极极柱,两个延伸枝节分别用于与电池中极芯的极耳电连接,两个延伸枝节间隔设置形成安装空隙,导热件设置在两个延伸枝节背离极芯的一侧,导热件覆盖安装空隙。本申请中的电芯引出片通过在其两个延伸枝节间的安装空隙处设置导热件,在不影响电芯引出片工作的情况下,增加了电芯引出片的散热面积,提升其散热性能。本申请还提供了一种电池和电动汽车。
