In this clip, you’ll learn more about “BMW Wireless Charging”, the technology that allows energy transfer to take place without the use of cables. Wireless charging for the high-voltage battery will be made available as an option for the BMW 530e iPerformance from 2018.
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.
This form of power supply to the high-voltage battery is extremely convenient for customers and involves a charging time of around three-and-a-half hours.
