A vehicle power supply includes an electric accumulator pack, an electric motor, first and second switches, an output determiner, and a switch controller. The electric accumulator pack includes first and second electric accumulators. The first and second switches are controlled between on- and off-states.

If at least one of the first electric accumulator or the second electric accumulator is in the first output state, the switch controller controls either one of the first and second switches to the on-state, and the other switch to the off-state. If both the first and second electric accumulators are in the second output state, the switch controller controls both the first and second switches to the on-state.
