Qualcomm expects easy-to-use wireless electric vehicle charging (WEVC) to become the de facto way all EVs are charged in the future.
Unlike some other inductive charging solutions that need pads to be closely aligned or almost touching, Qualcomm Halo™ technology delivers high energy transfer over a wide air gap—think SUV ground clearance.
The charging pad’s multi-coil design delivers high energy-transfer efficiency and high power – 3.3 kW and 6.6 kW - even if pads are misaligned.
Cables don’t offer significantly better power transfer efficiency—they have losses too. Qualcomm Halo™ actually benefits from its lack of physical connection, with efficiency that increases the higher the power level—think >90%.
Power transfer solutions have been developed to suit a broad range of vehicle types, from small urban commuters to high-performance racing machines.
The initial 3.3 kW system was installed on two Delta E-4 sports coupés for the UK CABLED EV trial and more recently upgraded to 6.6 kW.
At the luxury end of the market, this system was tested on the Rolls Royce Phantom 102EX Experimental EV that toured the world in 2011.
The record breaking Drayson B12/69 EV racecar took Qualcomm Halo™ into the world of high-performance motor sports at speeds of over 200 mph.
