A method is provided for balancing the voltage of multiple series-connected electrochemical cells of an electrical storage system of a hybrid electric vehicle. The method includes discharging the electrical storage system by operating at least one large electrical machine of the vehicle at vehicle standstill until the state of charge of the electrical storage system or the cell having the lowest state of charge has reached a predetermined level, and subsequently balancing the voltage of the cells.
