Nissan Motor Co Ltd disclosed that it is developing a contactless charging system for electric vehicles at its briefing session.
The company aims to employ the system for the "next generation" of its electric vehicle scheduled to be released in fiscal 2010.
This time, Nissan Motor equipped the "Hyper Mini," its electric vehicle launched in 2000, with the contactless charging system and had a demonstration of charging it. The system was developed by Nissan Motor and Showa Aircraft Industry Co Ltd. It is an electromagnetic induction type, which supplies electric power between a feeding coil and a receiving coil. The rated output is 10kW.
Nissan Motor is planing to offer the contactless charging system for the next-generation electric vehicle as an option. And it is considering a 3kW-class system for home use. As for the pricing, the company expects the vehicle-mounted system will be priced at several tens of thousands of yen.
Also, as a future challenge, Nissan Motor cited the need to establish a system that can ensure a high charging efficiency even when a feeding coil and a receiving coil are misaligned in a horizontal direction. Specifically, it aims to charge an electric vehicle when the two coils are misaligned as much as 100mm in a horizontal direction.
