NON-CONTACT CHARGING SYSTEM, NON-CONTACT CHARGING STAND, AND NON-CONTACT CHARGING METHOD

摘要

PROBLEM TO BE SOLVED: To avoid charge interruption caused by a trip of a breaker even when charge temperature rises in non-contact charging, with respect to a technology for performing non-contact power transmission between a charging stand and vehicle.SOLUTION: A temperature sensor measures temperature around a power path of a power conversion unit, and notifies a charge control unit of the temperature. The charge control unit monitors the temperature of the temperature sensor after starting charging a vehicle, corrects a charge permission current value when it is determined that the temperature has reached a temperature at which a breaker in the power conversion unit is interrupted, and notifies the vehicle side of the corrected charge permission current value through a radio communication unit. On the vehicle side, a charge control unit suppresses charge current to a battery unit according to the corrected charge permission current value when the radio communication unit receives the corrected charge permission current value. As a result, decrease in charge current flowing in the power conversion unit in a power supply device on the charging stand side avoids interruption of charging caused by a trip of a breaker.
