Abstract
A method and a system for balancing cells of a vehicle battery includes discharging charge from a highest charged cell for a discharge time period dependent on a charge difference between the highest charged cell and a lowest charged cell at a given time. The cells may be charged with the discharge charge during a charge time period.
