Non-contact charging

The system allows charging an EV without a connecting cable, simply by parking it in a designated spot, much like charging an electric toothbrush or shaver. Experiments on non-contact electric vehicle charging have been conducted in various locations, including Yukarigaoka, Chiba Prefecture, and the cities of Sakai, Osaka, and the cities of Nara, Nara Prefecture.


System outline

Electric power is supplied via magnetic induction from a primary power-supply coil in the parking surface to a secondary coil on the vehicle. When the primary coil is electrically charged, it generates a magnetic field that induces current in the secondary coil, and so charges the batteries with no wired connection.
