UK: Renault joins London wireless EV charging trial

(Phys.org) — Renault and Qualcomm this week signed a Memorandum of Understanding that they will cooperate on work at the upcoming London trial of Qualcomm Halo Wireless Electric Vehicle Charging (WEVC) technology, an event to take place in a few months. Preparations underway for the WEVC trial involve an assembly of government authorities and businesses, to install and test wireless electric cars. UK company Delta Motorsport, an automotive and motorsport engineering consultancy, has agreed to participate in trials carried out on specially adapted E4 coupes, and France-based Renault will use its vehicles too.

The Halo system, consisting of a charging terminal, flat pad and receiving pad on the car, transmits kilowatts of electricity over the air. There is a charging pad on which EV owners park their vehicles. The pad is activated by the presence of the vehicle, sending a charge through the air gap between the ground pad and the receiving pad. Halo uses electro-magnetic induction to transfer 3, 7 or even 20 kW of power between two coils. Transmission rates are reported as similar to what can be achieved with a traditional cable charger. Qualcomm claims that energy losses are small and as a result the charging method’s efficiency of 90 percent is comparable to conventional charging with a cable.
