One-Year Test of Three Vehicles in Japan’s Aichi Prefecture

Generating lots of headlines to the effect that it wants to unplug the electric vehicle, Toyota says it will begin testing a magnetic resonance wireless charging system on three plug-in hybrid vehicles in homes in Japan’s Aichi Prefecture later this month.

Toyota’s magnetic resonance-based wireless charging system includes a parking assist function showing the position of the transmitting coil in the parking space.

Toyota’s magnetic resonance-based wireless charging system includes a parking assist function to optimally position the vehicle above the power transmitting coil.

“The system can charge a vehicle parked in alignment over a coil on the surface of the ground, making the charging process simpler and more convenient,” Toyota says.

The magnetic resonance system is coupled with Toyota’s Intelligent Parking Assist option to make sure the vehicle being charged is optimally positioned over the charging coil, thus reducing drops in power transmission efficiency.

‘Commercialization Will Help Promote the Use of Electrified Vehicles’

“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,” Toyota says.

The three-PHEV verification test is initially planned to last one year. “The tests will assess user satisfaction, system ease-of-use, misalignment rates, and charging behavior, such as charging frequency and the use of timer-based charging…

“Toyota believes that commercialization will help promote the use of electrified vehicles and aid in making mobility that is smarter, easier to use and more environment-friendly.”
