The system consists of a base pad with integrated primary coil – which can be installed in a garage, for example, but also outdoors – and a secondary coil integrated in the underside of the vehicle.

An alternating magnetic field is generated between the two coils, through which electricity is transmitted without cables or contacts at a charge rate of up to 3.2 kW.
