Abstract
A battery system includes multiple battery cells having multiple cell voltages, and a balancing module. The battery module coupled to multiple battery cells and configured to specify a first voltage threshold according to an amount of a charging current supplied to the battery cells in constant current charging mode, and to initiate a balance check of the battery cells if the first voltage threshold is not satisfied by a cell voltage of the plurality of cell voltages.
