Charging Device for an Electric Vehicle
First Claim
1. A charging device for an electric vehicle having an electrical energy storage device, comprising:
- a first charging connector on a vehicle end for a mechanical connection to a second charging connector of an external charging station, wherein the first charging connector has two contact elements for direct current charging of the electrical energy storage device in the electric vehicle, which two contact elements are able to establish an electrical connection with the external charging station via contact thereof with two contacts of the second charging connector when the mechanical connection is established between the first and the second charging connectors;
a galvanic connection from the two contact elements to the electrical energy storage device, wherein, for direct current charging via the galvanic connection, direct current which is fed to the two contact elements of the first charging connector via the two contacts of the second charging connector flows into the electrical energy storage device for charging the same; and
a control device configured to monitor the charging of the electrical energy storage device, and to communicate with the external charging station;
wherein;
at least one of the two contact elements of the first charging connector is configured to move between a first and a second position, wherein the at least one contact element is withdrawn in the first charging connector when in the first position, and when in the second position is arranged such that contact is made with a corresponding one of the two contacts of the second charging connector when the mechanical connection is established between the first and the second charging connectors, andthe control device is further configured to control movement of the at least one contact element such that the at least one contact is only moved into the second position when the mechanical connection is established between the first and the second charging connector, and otherwise is in the first position.

Abstract
A charging device for an electric vehicle has a first charging connector on the vehicle side for mechanically connecting to a second charging connector of an external charging station. The first charging connector has two contact elements for a DC charging process. A galvanic connection of the contact elements to an electric energy store is provided, wherein direct current flows into the electric energy store. A control device monitors the charging process and is capable of communicating with the charging station. The charging device has at least one contact element movable between a first and a second position. In the first position, the contact element is retracted in the first charging connector, and in the second position the contact element is arranged so as to contact a corresponding contact of the second charging connector when the first and the second charging connectors are mechanically connected.
