Delphi Automotive has equipped an electric vehicle with its Delphi Wireless Charging
System, a highly efficient wireless energy transfer system featuring technology 
developed by WiTricity Corporation. [Delphi](https://greenlivingguy.com/2012/01/as-electric-vehicles-take-charge-costs-power-down/)
will display the test vehicle at this year’s SAE World Congress here this week.

“This is a significant advancement in our research and development efforts to offer
automotive manufacturers a practical wireless charging solution we believe is superior
to others being proposed,” said Randy Sumner, director, global hybrid vehicle development,
Delphi Packard Electrical/Electronic Architecture. According to Sumner, engineers
at Delphi’s Customer Technical Center in Champion, Ohio, have installed the Delphi
Wireless Charging System on an all-electric THINK City test vehicle, and have confirmed
that system performance meets automotive market requirements.

A wireless charging system eliminates the need for a charging cord. Drivers can 
simply park their electric vehicle over a wireless energy source situated on the
garage floor or embedded in a paved parking spot. Other wireless charging systems
under development make use of traditional inductive charging, the same technology
used in electric toothbrushes, which is based on principles first proposed in the
mid-nineteenth century. These systems only work over a limited distance range, require
precise accurate parking alignment and can be very large and heavy, making them 
impractical for widespread use on electric vehicles.

“The Delphi Wireless Charging System offers more practical and flexible installation
than traditional inductive systems because it uses highly resonant magnetic coupling,
a modern technology that safely and efficiently transfers power over significantly
larger distances and can adapt to natural misalignment often associated with vehicle
positioning during parking,” Sumner said. This means that Delphi charging sources
can be buried in pavement, are unaffected by environmental factors such as snow,
ice or rain, can accommodate a wide range of vehicle shapes and sizes and their 
differing ground clearances. The Delphi system is also more forgiving to vehicle
parking positions on top of the charger without requiring any moving parts to accommodate.
The system transfers energy using an oscillating magnetic field, which is intrinsically
safe for humans and animals.

According to Sumner, the system will automatically transfer power to the electric
vehicle’s battery pack at a rate of 3,300 watts — the same rate as most residential
plug-in chargers — and is able to do so with the smallest and lightest modules possible.
These components are important to minimizing overall vehicle weight and cost while
maximizing the driving range of EVs, a critical selling point for automakers.

“We are excited by our testing and validation of the system and believe we have 
a valuable and unique wireless charging solution that offers the most potential 
for widespread use in the automotive market. With the support of automotive manufacturers,
this technology can be integrated into the next generation of electric vehicles,”
Sumner said.

Wireless charging technology will need to co-exist with plug-in charging solutions,
he 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.
