Abstract
A contactless charging device for contactlessly charging an energy accumulator of a motor vehicle, wherein the contactless charging device has an interface for coupling the contactless charging device to a power source, wherein the interface is designed for communicative coupling and for wired electrical coupling to a charging station, wherein the charging station is designed for the wired charging of the energy accumulator.
Claims12
A contactless charging device for contactlessly charging an energy accumulator of a motor vehicle, the contactless charging device comprising:
- an interface for coupling the contactless charging device to a power source, the power source comprising at least one of a wall unit and a charging station, and
- an energy-transfer device for contactlessly exchanging electricity with the motor vehicle,
- wherein the power source is designed for wired charging of the energy accumulator,
- wherein the contactless charging device further comprises a rectifier circuit, an inverter arranged downstream of the rectifier circuit, and a bypass circuit configured to bypass the rectifier circuit,
- wherein the bypass circuit is open when the power source provides alternating current and the bypass circuit is closed when the power source provides direct current, and
- wherein the interface is designed for both communicative and wired electrical coupling to the power source.
A method for contactlessly charging an energy accumulator of a motor vehicle by a contactless charging device, comprising:
