ABSTRACT:
An inductive charger coupling for charging a battery includes a generally flat charging paddle and a charging receptacle. The charging paddle includes a primary core and a primary coil. The paddle is electrically connected to an external power supply. The charging receptacle includes a secondary core and a secondary coil. The receptacle is electrically connected to the battery. The secondary core engages the primary core when the charging paddle is plugged into the charging receptacle. The paddle lacks corners at its distal end, and the secondary core is shaped to conform to the distal end of the paddle, which narrows the overall width of the coupling.
