Inductive charging stations are using the electromagnetic field to transfer energy via two induction coils acting as electrical transformer. The first induction coil (sender) is located in charging base station and creates an alternating electromagnetic field. The second induction coil (receiver) located in vehicle takes power from the electromagnetic field and converts it back into electrical current to charge the battery. The proximity between these two coils are critical. Increasing the distance between coils is possible for inductive charging systems using resonant inductive coupling. Using high-frequency induction improves efficiency of such charging stations. The safety aspects of inductive charging for EVs used in public transportation require further investigation.
