A system for charging a battery includes a battery pack having at least two lithium ion cells. A controller detects a rate of change of voltage with respect to a state of charge (dV/dSOC) of the battery pack based on a calculated dV/dSOC that represents the battery pack as a whole, without calculating dV/dSOC individually on a cell-by-cell basis. Charging is terminated when dV/dSOC reaches a predetermined value.
