Delphi partners with WiTricity on automated wireless charging system
One could easily argue that parking between the white lines at any local hangout presents a challenge for some inexperienced drivers. So, why in the world would a company develop a system that forces drivers to align their vehicle over top of a 3,300 watt pad that's no bigger than a stop sign? The answer all boils down to simplicity. Delphi and WiTricity have teamed up to develop and market a wireless charging system for electric vehicles (EVs). Wireless charging uses an electromagnetic field to transfer energy between two objects. This action takes place without the need for a plug, and in the case of the Delphi-WiTricity design, will be activated the moment a vehicle is aligned with the charging pad below.
The system can charge battery-powered vehicles at a rate comparable to most home-based chargers, so we'd expect a full charge to take anywhere from two to eight hours depending on the vehicle's battery size. EV owners would only be tasked with parking their vehicles in alignment with the pavement-mounted pad and could then go about their day. Delphi envisions placing these charging systems in homes and embedded in company parking lots. One bump in the road still remains, though. Automakers, or some aftermarket company, will have to outfit battery-powered vehicles with a power capture resonator, and until that becomes a standard item on each and every EV, a nation dotted with wireless chargers remains just a dream.

Delphi Working to Make Electric Vehicle Wireless Charging a Reality
Revolutionary, green technology to help advance the establishment of a global infrastructure for electric vehicle charging
TROY, Mich. - Delphi Automotive has reached an agreement with WiTricity Corp., a wireless energy transfer technology provider, to develop automatic wireless charging products for hybrid and electric vehicles. The collaboration between the two companies will help establish a global infrastructure of safe and convenient charging options for consumer and commercial electric vehicles.
"This is groundbreaking technology that could enable automotive manufacturers to integrate wireless charging directly into the design of their hybrid and electric vehicles," said Randy Sumner, director, global hybrid vehicle development, Delphi Packard Electrical/Electronic Architecture. "Delphi's expertise in global engineering, validation and manufacturing coupled with WiTricity's patented wireless energy transfer technology uniquely positions us to make wireless charging of electric vehicles a reality."
Sumner said the wireless charging system would involve no plugs or charging cords. Drivers would simply park their electric vehicle over a wireless energy source that sits on the garage floor, or is embedded in a paved parking spot. The system will automatically transfer power to the battery charger on the vehicle.
According to Eric Giler, chief executive officer, WiTricity, their wireless system can already transfer over 3,300 watts - enough to fully charge an electric car at the same rate as most residential plug-in chargers.
"Charging an electric car should be as easy as parking it in your garage or parking spot," Giler said. "WiTricity's high efficiency wireless energy transfer technology is ideally suited for electric vehicle charging, and our partnership with Delphi will help to quickly get this technology deployed in OEM vehicles and infrastructure projects worldwide."
"Delphi can bridge the gap between the laboratory and the highway by providing E/E systems integration expertise, a global manufacturing and engineering footprint and high-voltage, high-power components specifically engineered for the hybrid and electric vehicles of today and tomorrow," Sumner said.
Wireless charging technology will need to co-exist with plug-in charging solutions, Sumner added, so that electric vehicle drivers have the ability to charge their vehicle when they are away from their wireless charging source.
Delphi also makes a Portable Electric Vehicle Charger that fits conveniently in the trunk of an electric vehicle. The user-friendly, UL-listed charging system plugs into any standard 120-volt outlet to enable safe electric vehicle battery charging at home or away. The charging unit can also be integrated into stationary charging applications.
