Wireless

A wireless charging system being jointly developed by Vahle and Hella uses the principle of inductive power transfer to recharge the battery pack of electrified vehicles.
Wireless charging’s key components are a primary coil and a secondary coil. The primary coil is located on the floor of a garage or a parking space. Mounted to the vehicle’s underbody is the secondary coil. Voltage supplied to the primary coil causes high-frequency alternating current to flow into the secondary coil. The secondary coil converts the magnetic field generated by the primary coil into induced voltage, and the resulting alternating voltage is converted into direct current by a rectifier.
