PROBLEM TO BE SOLVED: To secure necessary drive power while preventing system overvoltage in an electrical power source system equipped with plural electricity storage devices.SOLUTION: An electric power source system 110 supplying electric power to a drive device 105 comprises a first electricity storage device B1, a converter 120 which rises the voltage of the first electricity storage device and supplies to the drive device, a second electricity storage device B2 which is connected to the drive device in parallel with the converter, and an ECU 300. The ECU controls the converter by using either a power control mode which controls so that the electric power supplied from the first electricity storage device to the drive device is a target request electric power or a voltage control mode which controls so that a voltage applied to the drive device is a target voltage. The ECU corrects the target request electric power of the first electricity storage device on the basis of a difference between the target request electric power and the actual supply electric power of the second electricity storage device, in a case that the converter is operated under the power control mode. |
