BATTERY CHARGER, AND CHARGING STATION

WIPO Patent Application WO/2013/031589

A1

The present invention is capable of preventing elements from becoming destroyed by connecting a load resistor to the output side of a rectifier circuit and by preventing, by means of the load resistor, the voltage on the output side of the rectifier circuit from becoming high when the battery is not charged in a battery charger and charging station in which charging power is transmitted to the battery charger from the charging station by means of electromagnetic coupling and it is possible to transmit battery information as modulation signals from the battery charger to the charging station. This battery charger (50) is provided with a rectifier circuit (53) for rectifying the alternating current guided to a power reception coil (51) and for converting said alternating current to direct current for charging a battery (45), a modulation circuit (61) for transmitting a modulation signal to a charging station (10) by changing the load impedance of the reception coil (51), and a load resistor (56) connected to the output side of the rectifier circuit (53).
