Contactless charging and communication device for contactless charging of battery of electric car in charging station, has couplers for simultaneous and contactless transmission of energy and data from charging station to electronic unit

摘要

The device has couplers (3, 4) for simultaneous and contactless transmission of energy and data from a charging station (1) to an electronic unit (2) of an electric car, where the electronic unit is supplied with power by a stationary part and does not discharge a battery. The electronic unit receives current measurement values for identification, regulation and checking of a battery charging process. The electronic unit transfers recognition data over data couplers (9, 10) to the charging station so that the station recognizes a participant to be charged.
