摘要： A wireless charger for an electric vehicle includes a feeder module supplying power by approaching a location of a collector module in the vehicle and a robot arm aligning a location of the feeder module according to the location of the collector module. A feeder inverter converts externally applied power and supplies the converted power to the feeder module. The wireless charger simplifies charging in various ways. The user does not need to connect to a charger each time a vehicle is to be charged. Since the user does not directly touch a charging connector in case rain, safety accidents can be prevented. A robot arm can transfer a feeder module according to a location of a vehicle parked within a charging station further enhancing convenience. Furthermore, a collector module installed in a vehicle is sensed and a feeder module is aligned according to a location of the sensed module.
