Nissan to use Wireless battery charging

Nissan are said to be developing an inductive wireless charging system for their soon to be launched five-seat Zero Emissions Vehicle (ZEV) Electric Vehicle. The production version of the Nissan EV will get its official unveiling at the Tokyo Motor Show in October.

According to Larry Haddad, general manager of product strategy and planning at Nissan Europe, electromagnetic field technology can charge EVs in a compatible parking bay without the need for wires. Nissan has ambitions beyond mere wireless charging bays. It hopes to scale the technology up even further as a series of plates laid into the surface of designated electric vehicle lanes on our roads and motorways, theoretically enabling motorists to charge as they drive.

Nissan is grappling with its recent consumer research, which revealed that 61% of potential electric car customers were most worried about the inconvenience of recharging. As well as inductive charging, its technological solutions include developing fast-charging facilities, which they hope to see in place in shopping car parks and motorway service stations that can provide an 80% charge in as little as 25 minutes.

The ZEV will be the first "dedicated" electric car on the market, arguing that most rival cars have been rehashes of existing models. It is a five-seater family-sized car with a top speed of 90mph, a battery range of around 100 miles and impressive acceleration. The cars will be built so new, improved batteries can be retro-fitted.

Several companies have announced inductive wireless EV charging technology in resent weeks including WiTricity and Showa Aircraft Industry Co Ltd. No company has made mention of potential payment systems which has always been seen as a show stopper for wireless power. With the widespread use of short range radio based toll road tags having been adopted in many parts of the world over the last decade perhaps totally automated payment will be part of these wireless EV charging systems.
