Abstract

A coupling between a replaceable battery and a vehicle in order to produce an electrical contact between the battery and a vehicle electrical system. The coupling includes at least one vehicle-side coupling part and at least one battery-side coupling part, each coupling part having at least one electrical contact site. The contact sites of the coupling parts that are separate from each other until the battery is mechanically fastened to the vehicle can be brought into mutual contact after the battery has been mechanically fastened to the vehicle.

Claims

1-12. -12. (canceled)

13. A coupling between a battery and a vehicle, the coupling comprising:

at least one vehicle-side coupling part and at least one battery-side coupling part, each coupling part having at least one electrical contact site,

wherein in a first position in which the battery is not mechanically fastened to the vehicle, the at least one electrical contact sites of the coupling parts are separate from each, and in a second position in which the battery is mechanically fastened to the vehicle, the at least one electrical contact sites of the coupling parts are in mutual contact.

14. The coupling of claim 13, wherein the electrical contact sites of the coupling parts each form a plug-in connection.

15. The coupling of claim 13, wherein the vehicle-side coupling part is subjected to a restoring force that acts in an opposite direction to a coupling direction.

16. The coupling of claim 15, wherein the vehicle-side coupling part comprises at least one bias mechanism that generates the restoring force.

17. The coupling of claim 16, wherein the bias mechanism comprises a spring.

18. The coupling of claim 17, the spring comprises a helical spring that is guided on a spring spigot.

19. The coupling of claim 13, wherein the coupling parts are configured for mechanical coupling to each other.

20. The coupling of claim 19, wherein the mechanical coupling produces the electrical contact.

21. The coupling of claim 13, further comprising at least one switch arranged on at least one of the coupling parts.

22. The coupling of claim 21, wherein the at least one switch is configured for actuation when the electrical contact sites are connected.

23. The coupling of claim 22, wherein the at least one switch is connected to an output unit, at which the status of the electrical connection is indicated.

24. The coupling of claim 13, further comprising at least one guide spigot on at least one of the coupling elements that cooperates with a corresponding receiving device of the other coupling element.

25. The coupling of claim 13, wherein the coupling between the replaceable battery and the vehicle is configured to produce an electrical contact between the battery and an electrical system of the vehicle.

26. A vehicle comprising:

an electrical drive;

an electrical system;
