Abstract
The battery management unit for a vehicle includes a charger mounted on the vehicle, configured to connect to an external power source and charge an assembled battery including a plurality of cells with electric power from the external power source; a memory that records which cell is a lowest cell having the lowest voltage when the battery is fully charged; and a cell-balancer that carries out cell-balancing on the voltage of the battery by discharging, when the charger is not charging the battery, the cells having a voltage higher than a current voltage of the lowest cell to the current value of the lowest cell. Thereby, it is possible to suppress an increase in dispersion of voltages and reduction in battery capacity.
