The disclosure concerns a method for balancing the voltage of multiple series-connected electrochemical cells of an electrical storage system (20) of a hybrid electric vehicle. The method comprises discharging the electrical storage system (20) by operating at least one large electrical machine (21) of the vehicle at vehicle standstill until the state of charge of the electrical storage system (20) or the cell having the lowest state of charge has reached a predetermined level (11, 13), and subsequently balancing the voltage of the cells.
