BMW Revives Wireless Charging to Cut Electric Car Hassles

BMW AG is trying to make charging cables optional as it plans plug-in hybrid versions of top models from the 3-Series to the X5 sport-utility vehicle.

BMW will show wireless charging technology in the i8 hybrid sports car at this week’s Consumer Electronics Show in Las Vegas. Using a magnetic field to transmit electricity between a base pad on the garage floor or street and a coil on the underside of the vehicle, drivers would be able to avoid retrieving cables from the trunk and getting their hands dirty re-folding them.
