Some day you'll charge everything wirelessly -- phones, cars, graphing calculators, all using the same basic technology. That's the sort of utopian vision Toyota had in mind when it formed the Wireless Battery-charging Alliance with WiTricity. The young Massachusetts-based company is pushing "resonance" technology, which charges electronics without contact and is supposedly more efficient than induction-based charging -- a category that includes the popular Qi standard. This new partnership ups the ante, adding electric vehicles to the list of chargeable devices, a vision of the future where Prius batteries can be filled wirelessly, while sitting in driveways and parking garages. Exxon's engineers are no doubt working to perfect the hose-free gasoline transfer as we speak. PR after the break.

TMC and WiTricity Form Wireless Battery-charging Alliance

Toyota City, Japan, April 27, 2011-Toyota Motor Corporation (TMC) has entered into a technological collaboration agreement with Massachusetts, United States based WiTricity Corporation concerning the practical application of automotive wireless charging systems and the promotion of their widespread use. TMC plans to participate in a WiTricity capital increase.

WiTricity's charging technology uses resonance, which allows charging without direct contact and is more efficient than electromagnetic-induction, another wireless technology-but one that requires contact-that is starting to come of age in mobile phone and other chargers. TMC believes that resonance wireless charging is suitable for automobiles and aims for its early practical use.

The collaboration is aimed to accelerate development and eventual implementation of wireless charging for automobiles. The charging of a plug-in hybrid or electric vehicle could be as simple and convenient as parking near an embedded charger at a home or in a parking facility.

In the Toyota Global Vision announced in March, TMC expressed its commitment to leading the way to the future of mobility by integrating automobiles, homes and information technology. Wireless charging is just one of the many technologies TMC seeks to develop for the future.
