Abstract
A charge equalizing device for a power storage unit, which equalizes a remaining charge of each cell unit of the power storage unit that includes a plurality of groups of cells formed by a plurality of the cell units which are connected in series. The charge equalizing device includes a connection device which connects the groups of cells in series, the connection device being capable of connecting and disconnecting the groups of cells, a connection terminal provided for each of the cell units, and a switch device which connects one of the connection terminals of one of the groups of cells to another connection terminal of the other group of cells. The switch device is capable of changing the combination of the connection terminals to be connected.
Claims13
A charge equalizing device which equalizes a remaining charge of each cell unit of groups of cells formed by a plurality of the cell units which are connected in series, said groups of cells being negative terminal side group of cells and positive terminal side group of cells, said charge equalizing device comprising:
- a connection device which is capable of connecting and disconnecting the groups of cells;
- a connection terminal provided for each of the cell units;
- and
- a switch device which connects the connection terminal of one of the cell units of the positive terminal side group of cells to the connection terminal of one of the cell units of the negative terminal side group of cells, wherein
- combination of the connection terminals to be connected is changed in a process of equalizing the remaining charge of each of the cell units.
