Here's How BMW Wants You To Wirelessly Charge Your Car

And it only takes 3.5 hours.

Although it’s currently only an option on the overseas, this new method of wirelessly charging a car is sure to be applied to the rest of the automaker’s lineup. Presenting BMW’s wireless charging pad, which, according to , is still in the testing phase for the US and Canada. Here’s how it works: the pad itself, placed on the floor of the owner’s garage (outside is also possible), is connected to a 220-volt outlet. The pad features an integrated primary coil, while a secondary coil is located in the car’s underside.

A magnetic field is then generated between to the two coils, thus allowing for electricity to be transmitted without the need for any cables. With a charge rate of up to 3.2 kW, the vehicle can be fully charged from a depleted battery in just 3.5 hours. Owners can track the charging process through an app on their smartphones.

Eventually, BMW will be adding this wireless charging tech to additional iPerformance models, such as the 330e, 740e, and even the i3 and i8. As to when it’ll arrive stateside? Good question. BMW only told indicated to the plan definitely involves a North American market launch, but no exact timetable was given. Also no word on how much the feature will cost. Eventually, we predict that vehicular wireless charging will become quite common, specifically for autonomous vehicles used specifically for ride sharing in major cities.
