The bidirectional DC-DC converter is provided between the auxiliary battery and a power supply path from the main battery to a driving motor.

Abstract: A system for determining fixation of a relay has an electricity storage device, an electrical apparatus, a relay, a first insulation resistor, a second insulation resistor, a detection circuit, and a controller. When the relay is controlled to OFF, the controller determines, based on the voltage value detected by the detection circuit (the detected voltage value), whether or not the relay is fixed.

When the detected voltage value is a voltage value that is obtained by dividing the reference voltage value by the first resistance value and the reference resistance value, the controller determines that the relay is not fixed.
