BMW i launches BMW Wireless Charging

BMW Wireless Charging enables electric energy from the mains supply to be transmitted to a vehicle's high-voltage battery without any cables - when the vehicle is positioned over a base pad. This can be installed in the garage, for example, and the charging process starts as soon as the vehicle has been parked in position, without any further input from the driver.

The launch of this technology sees the BMW Group move another step closer to an infrastructure that will make charging the battery of an electrified vehicle even simpler than refuelling a car with a conventional engine.

Available to customers as an option, BMW Wireless Charging consists of a Inductive Charging Station (GroundPad), which can be installed either in a garage or outdoors, and a secondary vehicle component (CarPad) fixed to the underside of the vehicle.

The contactless transfer of energy between the GroundPad and CarPad is conducted over a distance of around eight centimetres. The GroundPad generates a magnetic field. In the CarPad an electric current is induced, which then charges the high-voltage battery.

The system has a charging power of 3.2kW, enabling the high-voltage batteries on board the BMW 530e iPerformance to be fully charged in around three-and-a-half hours. And with an efficiency rate of around 85 percent, charging with the BMW Wireless Charging system is very efficient, too.

The product offer starts with Germany, subsequently followed by the U.K., the U.S.A, Japan and China.
