The present invention relates to a device for balancing the overall levels of electrical charge in a plurality of blocks of cells in a battery. The blocks are able to be connected in a circuit during a charging phase during which the cells of the connected blocks accumulate charge, and during a discharging phase during which the cells of the connected blocks give back the charge in the form of an electrical current. The device comprises at least one series switch and one parallel switch. The series switch is able, when it is closed and the parallel switch is open, to connect a block to the circuit, in series with the other blocks, so that said block is connected during the charging and discharging phases. The parallel switch is able, when it is closed and the series switch is open, to disconnect said block from the circuit, so that said block is disconnected if discharging disconnection conditions are met during the discharging phase or if charging disconnection conditions are met during the charging phase, said block furthermore comprising means for balancing locally the charge levels of its cells when it is disconnected. |
