摘要： A battery is arranged outside a compartment. A service plug is arranged in the compartment. The service plug is a shutoff device that can shut off an output path of the battery by a manual operation. When a vehicle is hard hit at the front and a circuit of PCU is damaged, an excessive current may flow to the PCU, possibly generating heat or smoke from the PCU. When the vehicle goes wrong, a person on board the vehicle may pull out the service plug, whereby the power supply path from battery to PCU can be shut off.
