Abstract

An electrical connection line for charging an energy store of a motor vehicle has an electrical input connection (20) to connect the connection line (10) to an external energy source (24) and an electrical output connection (18) to connect the connection line (10) to the energy store (14) of the motor vehicle (12) that is to be charged. The electrical output connection (18) has a plug-in connector (18) for electrically connecting to the energy store (14) of the motor vehicle (12), and a line section (22) with at least two electrical lines for transferring electrical energy. The electrical input connection (20) has connection terminals (26, 28) to connect the connection line (10) to electrical contacts (30, 32) of the external energy source (24).

Claims
