High Power Inductive Charging System for an Electric Taxi Vehicle

In the city of Braunschweig five inductive charging stations for electric bus charging have been installed within an earlier research project named emil ("Elektromobilitat mittels induktiver Ladung" - translated "EMobility using inductive charging"). Further research activities focus now on charging cars on the bus-system ground units. This paper shows the conceptual design and the required measurements to charge electric taxis on the proprietary emil charging stations. One of the main targets is the development of a system that can be applied into a variety of different vehicles, being charged on the primary charging systems of the emil busses. It is presented how to implement the high power charging system in series production electric vehicles. This means that beside electromagnetic coil design and power electronic converter design a charging procedure is emulated on the prototype vehicle control unit to operate the inductive charging process.
