Toyota Testing Wireless Battery Charger
Toyota will begin verification testing of its newly developed wireless battery charging system for vehicles with an electrified powertrain. The company hopes to ultimately commercialize the technology used for plug-in hybrids and electric vehicles.
The tests will begin in late February in Aichi Prefecture, Japan. 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.
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 verification test will involve three plug-in hybrid vehicles in use in homes in Aichi Prefecture and 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.
The test results will be used to further develop the technology, with commercialization the ultimate aim. As electric vehicles become more popular, demand for charging stations is expected to surge.
