Claim:
1. A current transmission device for the stationary charging of vehicles ( 7 ) having electrical energy stores on charging stations by means of power-supplying contact surfaces ( 13 , 14 , 15 ) arranged above the vehicles, comprising: a charge current collector ( 4 ) formed as an articulated arm system and designed to be multi-pole for making stationary contact with the power-supplying contact surfaces ( 13 , 14 , 15 ), at least two electrical contact elements ( 1 , 2 , 3 ) transmitting different electrical phases, said at least two electrical contact elements ( 1 , 2 , 3 ) are arranged lying next to each other on an axis extending vertically to the driving direction and are isolated from one another on a common current charge collector ( 4 ), said articulated arm system allowing deploying and retracting of the at least two electrical contact elements ( 1 , 2 , 3 ), wherein at least one of said at least two electrical contacts elements ( 1 , 2 , 3 ) is formed as a grounding contact.
