The invention aims at stablizing power source voltage of a vehicle power source. The vehicle power source includes a generator motor coupled to an engine, a first power storage, a second power storage, a conduction switch, and a switch controller. The first and the second power storages are coupled, in parallel, to the generator motor. The conduction switch is subject to change between a conductive state and a cut-off state of the generator motor and the second power storage. The switch controller changes the conduction switch from the conductive state to the cut-off state, on a condition that the generator motor is controlled in a powered state. The switch controller changes the conduction switch from the cut-off state to the conductive state, on a condition that the second power storage discharges in excess of a threshold, with the conductive switch changed to the cut-off state. 本发明使车辆用电源装置的电源电压稳定。车辆用电源装置搭载于车辆，并具备：与发动机连结的启动发电机(16)；连接于启动发电机(16)的锂离子蓄电池(31)；与锂离子蓄电池(31)并联地连接于启动发电机(16)的铅蓄电池(32)；在将启动发电机(16)与铅蓄电池(
