The system main relay is configured to electrically connect a battery and an onboard device to each other by turning on a contact point, and to electrically disconnect the battery and the onboard device by turning off the contact point. The temperature measuring unit is configured to measure temperature of the contact point of the system main relay. The controller is configured to cause the system main relay to repeatedly turn on and off the contact point at a predetermined timing, (i) when the temperature of the contact point of the system main relay is a predetermined temperature or more or (ii) when an amount of rise in the temperature of the contact point is a predetermined amount or more.
