Lee said: "We believe Qualcomm is well positioned to make available this technology to third parties for the wireless charging of electric road vehicles, and the relationship will provide opportunities for continued research and development of this technology."
According to a fact sheet on the HaloIPT technology, http://www.haloipt.com/facts_sheet.pdf a system for domestic use for charging an electric car would converts single phase 50/60Hz AC mains power to 20kHz which is fed to a flat coil measuring 800mm x 400mm that sits on or just under the floor. The vehicle to be charge drives over this has a pickup coil and capacity combination tuned to the same frequency that converts to electrical energy the energy from the magnetic field generated by the ground coil. The system would consume about 3kw and have 85 percent efficiency.
HaloIPT says it is currently delivering units in the range 3 to 7kW able to operate over gaps up to 400mm and also developing higher power three phase systems for public charging.
However the fact sheet says: "IPT systems with power levels of up to 60kW based on technology developed by UniServices & its licensees have been successfully operating in buses for around 10 years, with fleets of over 20 buses based in Turin and Genoa."
It says that volume car components would be manufactured by established tier 1 suppliers. "Negotiations are in hand to achieve this. We have begun supplying evaluation systems to major tier 1 suppliers, OEMS and manufacturers. Primary-side power supply/ transmitter units will be manufactured under license to HaloIPT."
