Plugless Power[1] is a family of Electric Vehicle Supply Equipment (EVSE) products manufactured by Plugless Power, Inc. that enable wireless (inductive) charging for electric vehicles (WCEV).
[3] Evatran began selling the Plugless L2 Wireless charging system to the public in 2014.
[4] In simple terms, inductive charging works by separating the two halves of an electric transformer with an air gap – one half, the Plugless Power Vehicle Adapter, is installed on the vehicle and the other half, the Plugless Power Parking Pad, is installed on the floor of a garage or in a parking lot.
When a car with an Adapter drives over a Pad, the two pieces are brought into close proximity, 70–300 mm (2.8–11.8 in), then current from the electrical grid flows through the coils in the Power Pad to create magnetic fields and these fields induce current flow in the Vehicle Adapter's coils to charge the battery.
[6] As of October 2016, the Plugless L2 was being sold for use with the Nissan LEAF, Chevrolet Volt, Cadillac ELR and Tesla Model S.[7] In 2020, support for BMW i3 had been added, while the original plans were much more ambitious: targeting 80% of EVs by 2017.
