Rather than plugging in an electric vehicle (EV) to recharge the battery (conductive charging), inductive charging, also known as wireless charging, uses an electromagnetic field to transfer energy between the charging base and a vehicle's battery. Induction chargers typically use an induction coil to create an alternating electromagnetic field from within the charging base station, and a second induction coil in the portable device takes power from the electromagnetic field and converts it back into electrical current to charge the battery. The two induction coils form an electrical transformer.
