Charging Device for Charging an Electric Vehicle at a Charging Station
First Claim
1. An electric vehicle charging system comprising:
- a first charge module having a first electrical contact element including a guide sleeve slidable along a contact pin;
a second charge module having a second electrical contact element including contact plates coupled together by a spring, wherein a distance of the contact plates between one another depends on a contact force of the spring and the contact force depends on a position of the spring; and
wherein a position of the guide sleeve with respect to the second contact element affects the position of the spring and thereby affects the distance of the contact plates between one another such that the contact pin can be inserted between the contact plates without friction when the charge modules are joined together.

Abstract
A charging system for charging an electric vehicle at a charging station includes a charge module at the charging station and a charge module at the vehicle. The charge modules include electric contact elements which can be interconnected together. The charging system includes an automatic positioning device configured to move the charging station charge module relative to the vehicle charge module to align and join the charge modules together. The charging system includes an automatic feed device configured to enable the contact elements of the charging station charge module to connect to the contact elements of the vehicle charge module when the charge modules are joined together. The contact elements of the charge modules are configured such that the contact elements can connect to each other without overriding a contact force.

13. A charging system for charging an electric vehicle at a charging station, the charging system comprising:
-
a first charge module of a charging station, the first charge module having a first electrical contact element including a contact pin and a guide sleeve, wherein the guide sleeve is slidable along a contact pin; a second charge module of an electric vehicle, the second charge module having a second electrical contact element including contact plates, a spring, and a contact carrier, wherein the contact plates ae coupled together by the spring and the spring is coupled to the contact carrier, a distance of the contact plates between one another depends on a contact force of the spring, the contact force depends on a position of the spring, and the position of the spring depends on a position of the contact carrier; and wherein a position of the guide sleeve along the contact pin with respect to the second contact element affects the position of the contact carrier thereby affecting the position of the spring and the distance of the contact plates between one another such that the contact pin can be inserted between the contact plates without friction when the charge modules are joined together. - View Dependent Claims (14, 15, 16, 17)
