Highly Efficient Inductive Charging Systems
The compactness of the vehicle side coils is outstanding, coupled with a similarly high transmission efficiency of up to 97 %. For local communication between the charging point and the car, a low data rate and robust communication channel in the energy transmission system (with a maximum output of 3.5kW) was successfully integrated. Therefore, the existing transmission coils can be used and radio modules are not necessary. With near-field communication, important status updates of the charging process can be transmitted.
