Chongqing Chongqing lithium battery assembly technology training school, Huacheng Vocational School lithium battery assembly maintenance training class.

The assembly methods of lithium batteries can be divided into two forms, one is the production assembly of lithium battery manufacturers, and the other is the DIY assembly of personal purchase of batteries. When selecting the lithium battery cells to be assembled, we should not only pay attention to the brand quality of the cells, but also pay attention to the consistency errors between the cells in voltage, internal resistance, capacity, discharge performance and so on. The smaller the error, the better. Do not mix old and new batteries, which will damage the new batteries too quickly and affect the life of the whole battery pack; Lithium batteries with different performances cannot be mixed, that is, high-temperature batteries cannot be mixed with ordinary batteries, and low-temperature batteries cannot be mixed with high-temperature batteries. When assembling lithium batteries, it should be noted that batteries cannot be used in infinite series and parallel, but are limited by battery quality and battery management system level; Pay attention to short circuit during assembly to avoid accidents; Measures that can be handled safely after the accident should be prepared in advance.
