Toyota Begins Wireless Charging Verification Tests Using Prius Plug-In Hybrid (w/video)
Toyota Motor Corporation announced the beginning of verification testing of its newly developed wireless charging system. Testing will commence in late February in Aichi Prefecture, Japan.
Three Prius plug-ins, fitted with a 2 kW receiver, will be able to recharge in 90 minutes.
A trick feature is that Intelligent Parking Assist is coupled with wireless charging, which means that car can not only park itself, but will park exactly in the right position to maximize efficiency.
“The charging system uses magnetic-resonance technology, which transmits electricity by utilizing the magnetic resonance resulting from changes in magnetic field intensity between a coil on the ground that transmits and a coil on the vehicle that receives. The system can reduce drops in power transmission efficiency that can be caused by misalignment or height differences between the transmitting coil and receiving coil. Created with future market launch in mind, the system is designed to minimize electromagnetic interference on nearby equipment and the ground-installed transmitting coil is robustly structured to withstand a vehicle driving over it.”
The ultimate goal for Toyota is to commercialize such a system and this is probably why the Japanese company is investing in WiTricity
