Abstract:
Provided is a power supply device for a vehicle in which charge movement between a plurality of cell groups can be suppressed. The plurality of cell groups each include a plurality of cells connected in series to each other and are each provided on one of the plurality of wiring paths. A plurality of switches are connected in series to the plurality of cell groups in the plurality of wiring paths. A deterioration diagnosis unit specifies, from the plurality of cell groups, a deteriorated cell group that has deteriorated. A switch controller turns off, among the plurality of switches, a deteriorated switch that is connected to the deteriorated cell group.

Claim (Index 1):
An in-vehicle power supply device to be installed in a vehicle, comprising:\n a plurality of wiring paths connected in parallel to each other; a plurality of cell groups that each include a plurality of cells connected in series to each other and are each provided on one of the plurality of wiring paths; a plurality of switches that are connected in series to the plurality of cell groups in the plurality of wiring paths; a deterioration diagnosis unit configured to specify, from the plurality of cell groups, a deteriorated cell group that has deteriorated; a switch controller configured to turn off, among the plurality of switches, a deteriorated switch that is connected to the deteriorated cell group; a voltage detection unit configured to detect a terminal voltage that is applied between both ends of each of the plurality of cell groups; and an electric current detection unit configured to detect an electric current that flows through each of the plurality of cell groups, wherein the deterioration diagnosis unit:\n calculates a resistance value of an internal resistance of each of the plurality of cell groups based on the terminal voltage, the electric current, and an open-circuit voltage of each of the plurality of cell groups, and \n specifies, from the plurality of cell groups, any cell group whose resistance value is larger than a resistance reference value, as a deteriorated cell group.
