CHARGE SYSTEM, CHARGER, AND METHOD FOR DETECTING CLOSING/FIXING OF RELAY

WIPO Patent Application WO/2010/113904

A1

Provided is a technology which can be applied to an electric vehicle without any additional cost so that the closing/fixing of a relay can be detected, and the relay can be reliably opened, except for the period in which a battery is charged. Relays (205A, 205B) are operated by electrical power for control which is supplied from a charger (100) via a vehicle-side connector (201). An electric vehicle (200) closes the relays (205A, 205B) before a vehicle-mounted battery (203) is charged, and opens the relays (205A, 205B) after the vehicle-mounted battery (203) is charged. The charger (100) begins supplying electric power for control via a charger-side connector (101) before the vehicle-mounted battery (203) is charged, and maintains the supply of the electric power for control after the supply of electric power for charge is stopped by the completion of charging of the vehicle-mounted battery (203). Further, the output voltage of the electric power for charge is measured and notified to the electric vehicle (200). The electric vehicle (200) detects the closing/fixing of the relays (205A, 205B) on the basis of the measured value.
