电池进行电性能测试时,接触内阻需小于 0.2mΩ。如无特殊要求,电池进行电性能测试和寿命测试时,需要对电芯进行 Bar 片焊接,实现与测试柜之间的电压连接和电流连接。焊接Bar 片后示意图如下。 When the cell is tested for electrical performance, the contact resistance should less than 0.2mΩ. If there are no special requirements, when the cell is tested for electrical performance and life, it is necessary to weld the Bar sheet of the cell to achieve voltage connection and current connection between the test device. The diagram after welding Bar sheet is as follows.
