VEHICLE POWER SUPPLY DEVICE AND MALFUNCTION DIAGNOSIS METHOD THEREOF

摘要

A vehicle power supply device including a power storage device includes: an inlet that is coupled to an external power supply via a charging cable when the power storage device is charged using the external power supply; an outlet that is coupled to an external device when power is supplied from the power storage device to the external device; a first power converter that is formed between the inlet and the power storage device and converts alternating current (AC) power into direct current (DC) power; a second power converter that is formed between the outlet and the power storage device and converts DC power into AC power; and, a malfunction diagnosis unit that diagnoses malfunction of a power supply path in a state in which the inlet and the outlet are coupled to each other using the charging cable.
