Audi Wireless Charging for E-tron
The idea is that the future customer of an electric vehicle from Audi e-tron does not have to worry about plugging the car to the power supply or charging post. Bjorn Elias is the project manager at Audi Electronics Venture GmbH (AEV), a subsidiary of Audi AG. In this area, AEV is responsible for identifying new trends, ensuring their suitability and feasibility, as well as prepare for potential mass production in cooperation with external companies if necessary.
One of the Audi partners in research for wireless charging is WiTricity Corporation, based in Boston. The American company provides technical components that are integrated into the vehicle and in the system, such as coils or plates integrated induced induction. The primary coil is usually located on the floor, for example in a parking space, while the secondary or induced coil is placed in the bottom of the car Audi e-tron.
When the Audi e-tron, or other vehicle equipped with this technology conveniently stops in the area which houses the primary armature, automatically starts the recharging process. The alternating current flowing in the primary coil generates a magnetic field which causes a voltage induced in the coil integrated in the vehicle. The current is rectified and passed to feed the vehicle batteries. The process ends automatically when the battery is fully charged.
