A power system comprises an assembled battery in which a plurality of unit cells are connected in series and which supplies power from the series circuit of the unit cells to a device, a power generator for parallely supplying generated power to the assembled battery and the device connected in parallel, a plurality of forced discharge units for forcedly making the plurality of unit cells discharge individually, a cell state detecting unit for detecting the state of each unit cell, and a controller for, when at least one of the plurality of unit cells is detected by the cell state detecting unit to be in a first state showing that the unit cell is not fully charged, making the unit cell, which is detected to be in the first state, discharge until the cell unit is detected to be in a second state in which the state of charge is lower than that in the first state. |
