Delphi Exploring Wireless Charging System for Electric Vehicles

Plugging in an electric vehicle to recharge its battery may not be an issue for homeowners with a garage. However those without a safe place to plug in at night may worry about their vehicle being tampered with when they're not around. Automotive supplier Delphi is currently working on a wireless charging system for plug-in vehicles that could help solve the problem.

Delphi teamed up with wireless energy transfer company WiTricity to develop a wireless charging system for EVs and plug-in hybrids. With no plugs to speak of, drivers would simply park their vehicle on the mat and wireless charging would automatically begin.

Electricity flows upward from the mat to a power capture resonator that will need to be installed on the car for the system to work. According to WiTricity, the system transfers 3300 watts and can charge a vehicle in a similar amount of time as if it were plugged into a standard household outlet. Depending on vehicle height, the electricity will have an eight to twelve inch gap to travel for the vehicle to capture it.

Delphi says the mat can be permanently paved into parking spots for public access, or a portable mat may be laid in an owners garage and transported as needed. Although the system isn't ready for public use, industry experts say its price needs to be no more than $1000 to keep consumers interested.

What do you think? Will wireless charging become the charging standard for EVs, or is this technology going nowhere? Give us your thoughts in the comments section below.
