Patent attributes
A vehicle-mounted charging system is provided that can charge a battery regardless of the charging method and prevent an abnormal current from occurring between a vehicle and a charging station. A first charging controller, controls charging in accordance with a first charging method, communicates with a first charging apparatus via a charging cable connected to a first inlet, and charges a battery by turning on a DC cutoff relay, provided on a power supply path from the first inlet to the battery. If it is determined that charging is to be performed in accordance with a second charging method, a charging control unit relays communication between a second charging apparatus and the first charging controller. The charging control unit performs control to delay the timing of actually turning on the DC cutoff relay relative to the timing at which the first charging controller turns on the DC cutoff relay.
