A vehicle may include an electric machine that generates motive power for the vehicle, a plurality of cells that store energy for the electric machine, and at least one controller. The at least one controller may cause the cells to receive current for a period of time and, during the period of time, cause at least some of the cells to supply cell load current such that at the expiration of the period of time, the amount of energy stored by the cells is at least equal to a predetermined target energy level.
