Abstract

The invention discloses a battery cell assembly and a battery device, and the battery cell assembly comprises at least two battery cells with pole columns; the connecting piece is connected between the poles of the two battery cells; and the heat dissipation structure is connected to the connecting piece. According to the technical scheme, the heat dissipation efficiency of the connecting sheet is improved through the heat dissipation structure, so that the problem that the performance of the battery cell is influenced by over-high temperature rise is avoided.

Description

technical field [0001] The invention relates to the technical field of battery devices, in particular to a battery cell assembly and a battery device. Background technique [0002] A battery pack, such as a battery pack configured on a new energy vehicle, is usually composed of several battery modules, and the battery module is composed of several battery cells. The connecting piece is fixed on the pole of the battery cell and used for To form a series or parallel relationship between different battery cells. When the current value of charging and discharging of the battery pack is large, the temperature rise of the connecting piece is high, and the heat will be transferred to the inside of the battery cell, thereby affecting the working performance and life of the battery cell. Contents of the invention [0003] The main purpose of the present invention is to provide a battery cell assembly, which aims to improve the heat dissipation efficiency of the connecting piece th...
