Abstract

A motor vehicle with a traction battery and a connection device. The traction battery can be connected to an energy source external to the vehicle for recharging. In this case, the connection device has an electrical charging cable and a rotatably mounted cable reel for taking up the charging cable. The charging cable be guided in a longitudinal beam of the motor vehicle configured as a hollow profile.

First claim

The invention claimed is:

1. A motor vehicle comprising:
a traction battery and a connection device, by which the traction battery can be connected to an energy source external to the vehicle for recharging, wherein the connection device includes an electrical charging cable and a rotatably mounted cable reel for taking up the charging cable, wherein the charging cable is guided in a longitudinal beam of the motor vehicle configured as a hollow profile, wherein the longitudinal beam is designed as a front longitudinal beam and the cable reel is arranged in a radiator tank of the motor vehicle.

2. The motor vehicle as claimed in claim 1 , wherein the connection device includes a spring-loaded winding-up mechanism for the automatic winding up of the charging cable on the cable reel and a locking mechanism for the reversible releasable locking of the winding-up mechanism and/or for the reversible releasable retaining of the charging cable in various winding states.

3. The motor vehicle as claimed in claim 1 , wherein the connection device includes a motor-driven winding-up mechanism for the automatic winding of the charging cable onto the cable reel.

4. The motor vehicle as claimed in claim 1 , wherein the motor vehicle has a heat conductive cooling mechanism connected to the cable reel, preferably comprising a circulation of coolant.

5. The motor vehicle as claimed in claim 1 , wherein the motor vehicle has a heat conductive cooling mechanism connected to the charging cable, preferably comprising a circulation of coolant.

6. The motor vehicle as claimed in claim 5 , wherein the charging cable can accept a flow of liquid and is connected to the circulation of coolant of the motor vehicle.

7. The motor vehicle as claimed in claim 1 , wherein the motor vehicle has a retaining mechanism for holding a charging plug of the charging cable in a stowed position, from which the charging plug may be removed for connecting to the energy source external to the vehicle.

8. A motor vehicle comprising:
a traction battery and a connection device, by which the traction battery can be connected to an energy source external to the vehicle for recharging, wherein the connection device includes an electrical charging cable and a rotatably mounted cable reel for taking up the charging cable, wherein the charging cable is guided in a longitudinal beam of the motor vehicle configured as a hollow profile, wherein the longitudinal beam is designed as a rear longitudinal beam and the cable reel is arranged in a spare tire cavity of the motor vehicle.

9. The motor vehicle as claimed in claim 8 , wherein the connection device includes a spring-loaded winding-up mechanism for the automatic winding up of the charging cable on the cable reel and a locking mechanism for the reversible releasable locking of the winding-up mechanism and/or for the reversible releasable retaining of the charging cable in various winding states.

10. The motor vehicle as claimed in claim 8 , wherein the connection device includes a motor-driven winding-up mechanism for the automatic winding of the charging cable onto the cable reel.

11. The motor vehicle as claimed in claim 8 , wherein the motor vehicle has a heat conductive cooling mechanism connected to the cable reel, preferably comprising a circulation of coolant.

12. The motor vehicle as claimed in claim 8 , wherein the motor vehicle has a heat conductive cooling mechanism connected to the charging cable, preferably comprising a circulation of coolant.

13. The motor vehicle as claimed in claim 12 , wherein the charging cable can accept a flow of liquid and is connected to the circulation of coolant of the motor vehicle.

14. The motor vehicle as claimed in claim 8 , wherein the motor vehicle has a retaining mechanism for holding a charging plug of the charging cable in a stowed position, from which the charging plug may be removed for connecting to the energy source external to the vehicle.
