Description

technical field [0001] The invention belongs to the technical field of battery production and manufacture, in particular to a battery module. Background technique [0002] In today's society, with the improvement of people's awareness of environmental protection, more and more people choose to buy new energy vehicles with low energy consumption. New energy vehicles mainly use electric energy as the main power source. [0003] New energy vehicles are divided into pure electric vehicles and hybrid vehicles, but no matter which one is, they are inseparable from battery modules to provide power for them. A battery module generally includes a casing, a cell, a busbar, and a busbar protective casing. The cell is arranged inside the casing. Because the casing itself has a certain thickness, it will cause the heat generated by the cell during operation. It cannot be quickly dissipated, which reduces the heat dissipation speed of the cells. Multiple groups of cells are constructed t...
