What if we are building a huge battery pack that contains more then 100 or even more cells? In a high-voltage battery with many cells in series, though, there is a much greater chance that the overall pack voltage is not evenly divided among its cells.(This is true for any chemistry.) Consider a four-cell LiPo battery, charged up to 16.8V.

Battery module and pack testing involves very little testing of the internal chemical reactions of the individual cells. Module and pack tests typically evaluate the overall battery performance, safety, battery management systems (BMS), cooling systems, and internal heating characteristics.
There is significantly less time available to test during production due to high throughput. Typically the system validation done on the pack level can easily take upwards of 6 minutes per unit. For example, an EV battery manufacturer may plan to manufacture up to 40,000 or more battery packs a year.
