Ref lithium battery pack balance:

Power lithium-ion batteries sometimes require several, dozens or even hundreds of strings, and these batteries may find unbalanced conditions in use. This is because the production of batteries needs to go through many processes. Although they have undergone very strict inspections at the end, after all, various differences will occur in the production process. After a period of use, these differences will begin to slowly start. appear.

At this time, if it is a battery pack composed of multiple batteries, the capacity of the entire battery pack depends on the cell capacity of the battery with the worst capacity in the entire battery pack. This is the famous barrel theory.

Faced with such a problem, a corresponding protection circuit should be set up for the battery to extract excess power from the higher-voltage battery, so that the power of the entire battery pack can be balanced. There are two commonly used balance methods: energy balance and resistance balance.
