This chapter discusses various battery balancing methods, including battery sorting, passive balancing, and active balancing. Battery sorting is used in the initial state of making a consistent battery pack. The passive balancing and active balancing are used in the operation of the battery pack. Two battery sorting methods are presented. One is to sort the battery cells into the group by directly comparing battery parameters of cells. The other is to sort the battery cells into the group using the Self‐organizing Map (SOM). In passive balancing, the fixed shunt resistor, switched shunt resistor or switched transistor balancing circuits are presented to explain the working principle of passive balancing. In active balancing, balancing criterion, balancing control, and balancing circuits are discussed. Two active balancing systems are used to demonstrate the capacity improvement of battery packs from the perspectives of selecting a balancing criterion and designing a balancing controller.
