In a new Youtube video, BMW talks again about the “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.
We first experience the wireless charging technology in April 2017 when BMW allowed us to drive a 530e onto the charging pad and explore the new technology.
After the BMW 530e, additional models with the optional BMW Wireless Charging package will be available within a short time. In addition to the vehicle, the floor plate must also be bought for operation, which can be obtained from the dealership, similar to conventional wallbox solutions from BMW i and iPerformance.
According to the BMW, the price is not yet fixed, but it should only be slightly above the current BMW i Wallbox Pro, which is currently priced at around $900.
