Abstract

The battery management unit for a vehicle includes a charger (14) mounted on the vehicle (10) for charging an assembled battery (13) including a plurality of cells (9) with electric power from an external power source; a memory (1) that records which cell is a lowest cell having the lowest voltage when the assembled battery (13) is fully charged; and a cell-balancer (5) that carries out cell-balancing on the voltage of the assembled battery (13) by discharging, when the charger (14) is not charging the assembled battery (13), one or more cells (9) each having a voltage higher than a current voltage of the lowest cell (9) to the current value of the lowest cell (9). Thereby, it is possible to suppress an increase in dispersion of voltages and reduction in battery capacity.
