Google has been testing two wireless charging systems for its prototype
electric driverless cars in California.
Two companies (Hevo Power and Momentum Dynamics) received permission from the U.S. Federal Communications Commission (FCC) to install experimental chargers for Google.
This approach is in line with other tests, such as the British recharging lanes.

Nevertheless, wireless charging for electric passenger cars is already available. A company called Plugless Power offers one-off home charging units for private owners of vehicles such as Nissan Leafs.
Both companies’ systems transfer power from a transmitter embedded in the ground to a receiver on the underside of an electric vehicle, using a principle called resonant magnetic induction, which is somehow similar to the technology used for induction cookers.
Google's wireless charging system seems to be more practical at this stage than Tesla's current approach:
