Abstract
An inductive charger coupling for charging a battery. The coupling includes a charging paddle and a charging receptacle. The paddle is connected to an external power source and includes a primary core and a primary coil. The receptacle is connected to the battery and includes a secondary core, a secondary coil and a housing. The housing accommodates the secondary core and the secondary coil. When charging the battery, the paddle is inserted in the receptacle. The housing conforms to the secondary core and the secondary coil and has radiator fins on its outer surface. The housing and the fins reduce the size of the coupling while improving the cooling efficiency.
