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
