Abstract
An on-board electrical system includes a motor generator, a high-voltage battery, an electric power acquirer, an auxiliary subsystem, first and second step-down units, and a controller. The electric power acquirer is able to acquire electric power during travel of a vehicle, and able to feed acquired electric power to the high-voltage battery. The auxiliary subsystem includes an auxiliary battery and auxiliary machinery. The controller determines whether or not magnitude of a load on the auxiliary battery is equal to or greater than predetermined magnitude. On the condition that the magnitude of the load is equal to or greater than the predetermined magnitude, the controller allows electric power from the electric power acquirer to be fed to the auxiliary subsystem through the second step-down unit.
