Abstract

A charging harness unit for a battery of a motor vehicle includes a charging harness which has at least one lead and respective ends, one end being on the battery side and the other end being for connecting to a vehicle-external charging station. A cooling channel through which a coolant can flow is arranged in the charging harness. The cooling channel can be supplied with the coolant via a cooling device arranged on the vehicle side.

Claims (49)

1. A charging harness unit for a battery of a motor vehicle, comprising:

a charging harness having at least one lead and first and second ends, the first end being on a battery side and the second end being connectable to a charging station that is external to the vehicle, wherein

a cooling channel through which a cooling fluid flows is arranged in the charging harness,

the cooling channel is supplied with the cooling fluid via a cooling device arranged on a vehicle side, and

a deflection is provided at one of the first and second ends and is configured to cause the fluid that flows through the cooling channel in a first direction to flow through the cooling channel in a second direction opposite to the first direction.

2. The charging harness unit according to claim 1 , wherein

the charging harness has exactly two leads.

3. The charging harness unit according to claim 1 , wherein

the deflection, is configured to deflect the cooling fluid from at least one of the leads into at least one other of the leads.

4. The charging harness unit according to claim 1 , wherein

a cooling-fluid inlet and a cooling-fluid outlet, via which the charging harness is fluidically connected to the cooling device, are provided at one of the first and second ends.

5. The charging harness unit according to claim 1 , wherein

the at least one lead has a central cooling-fluid hose for conducting the cooling fluid, an inner conductor for conducting electrical energy, a shielding, and at least one insulation.

6. The charging harness unit according to claim 1 , wherein

the at least one lead has a central lead core that is wrapped helically by at least one cooling-fluid hose.

7. The charging harness unit according to claim 1 , wherein

for exchanging cooling fluid with the battery, the first end of the charging harness that is assigned to the battery is fluidically couplable to the battery.

8. The charging harness unit according to claim 1 , wherein

the charging harness is fluidically couplable to the cooling device with bypassing of the battery.

9. A charging harness unit for a battery of a motor vehicle, comprising:

a charging harness having at least one lead and first and second ends, the first end being on a battery side and the second end being connectable to a charging station that is external to the vehicle, wherein

a cooling channel through which a cooling fluid flows is arranged in the charging harness,

the cooling channel is supplied with the cooling fluid via a cooling device arranged on a vehicle side, and

the at least one lead has a central cooling-fluid hose for conducting the cooling fluid, an inner conductor for conducting electrical energy, a shielding, and at least one insulation.

10. The charging harness unit according to claim 9 , wherein

the charging harness has exactly two leads.

11. The charging harness unit according to claim 9 , wherein

a deflection, by which the cooling fluid is deflected from at least one of the leads into at least one other of the leads, is provided at one of the first and second ends.

12. The charging harness unit according to claim 9 , wherein

a cooling-fluid inlet and a cooling-fluid outlet, via which the charging harness is fluidically connected to the cooling device, are provided at one of the first and second ends.

13. The charging harness unit according to claim 9 , wherein

for exchanging cooling fluid with the battery, the first end of the charging harness that is assigned to the battery is fluidically couplable to the battery.

14. The charging harness unit according to claim 9 , wherein

the charging harness is fluidically couplable to the cooling device with bypassing of the battery.

15. A charging harness unit for a battery of a motor vehicle, comprising:

a charging harness having at least one lead and first and second ends, the first end being on a battery side and the second end being connectable to a charging station that is external to the vehicle, wherein

a cooling channel through which a cooling fluid flows is arranged in the charging harness,

the cooling channel is supplied with the cooling fluid via a cooling device arranged on a vehicle side, and

the at least one lead has a central lead core that is wrapped helically by at least one cooling-fluid hose.

16. The charging harness unit according to claim 15 , wherein

the charging harness has exactly two leads.

17. The charging harness unit according to claim 15 , wherein

a deflection, by which the cooling fluid is deflected from at least one of the leads into at least one other of the leads, is provided at one of the first and second ends.

18. The charging harness unit according to claim 15 , wherein

a cooling-fluid inlet and a cooling-fluid outlet, via which the charging harness is fluidically connected to the cooling device, are provided at one of the first and second ends.

19. The charging harness unit according to claim 15 , wherein

for exchanging cooling fluid with the battery, the first end of the charging harness that is assigned to the battery is fluidically couplable to the battery.

20. The charging harness unit according to claim 15 , wherein

the charging harness is fluidically couplable to the cooling device with bypassing of the battery.
