Kabelgebundenes und kabelloses bidirektionales Laden von Elektrofahrzeugen

To increase the availability of electric vehicles the possibility to charge from any publicly available power connection type has to be guaranteed. For this purpose a highly flexible bidirectional battery charger has been devised witch is capable to charge from a single phase, a three phase connection and a wireless energy transfer. Ancillary services for the electrical grid are possible due to the bidirectional power flow capability. Due to the multiple use of components such as power semiconductors, cooling and inductors in this converter a dramatical cost and the volume reduction is expected. In this work a complete on-board charging infrastructure is discussed, analyzed and experimentally validated.
