Abstract

A liquid cooled charging cable system may be provided. The liquid cooled charging cable system may comprise a source, a load, a liquid cooled charging cable, and a cooling device. The liquid cooled charging cable may connect the source to the load, and may supply electric energy from the source to the load. The liquid cooled charging cable may comprise a supply conductor and a return conductor. The cooling device may pump a coolant around the supply conductor and the return conductor where the supply conductor and the return conductor may be immersed in the coolant.

Claims (48)

1. A cable comprising:

a first supply hose comprising;

a first supply hose interior surface,

a first supply hose interior cavity defined by the first supply hose interior surface, and

a first supply sub-conductor being disposed within the first supply hose interior cavity, wherein a first supply hose interior space is formed between the first supply sub-conductor and the first supply hose interior surface within the first supply hose interior cavity, and wherein the first supply hose interior space provides a first supply pathway for first supply hose coolant;

a first return hose comprising;

a first return hose interior surface,

a first return hose interior cavity defined by the first return hose interior surface, and

a second supply sub-conductor being disposed within the first return hose interior cavity, wherein a first return hose interior space is formed between the second supply sub-conductor and the first return hose interior surface within the first return hose interior cavity, and wherein the first return hose interior space provides a first return pathway for the first supply hose coolant supplied through the first supply hose interior space by merging the first supply hose to the first return hose at a load;

a second supply hose comprising;

a second supply hose interior surface,

a second supply hose interior cavity defined by the second supply hose interior surface, and

a first return sub-conductor being disposed within the second supply hose interior cavity, wherein a second supply hose interior space is formed between the first return sub-conductor and the second supply hose interior surface within the second supply hose interior cavity, wherein the second supply hose interior space provides a second supply pathway for second supply hose coolant, and wherein the first supply pathway and the second supply pathway are connected to a main supply pathway through a first conduit bifurcation point;

a second return hose comprising;

a second return hose interior surface,

a second return hose interior cavity defined by the second return hose interior surface, and

a second return sub-conductor being disposed within the second return hose interior cavity, wherein a second return hose interior space is formed between the second return sub-conductor and the second return hose interior surface within the second return hose interior cavity, wherein the second return hose interior space provides a second return pathway for the second supply hose coolant supplied through the second supply hose interior space by merging the second supply hose to the second return hose at the load, wherein the first supply hose coolant is supplied by a cooling device and returns to the cooling device via the first return hose, wherein the second supply hose coolant is supplied by the cooling device and returns to the cooling device via the second return hose, and wherein the first return pathway and the second return pathway are connected to a main return pathway through a second conduit bifurcation point; and

a jacket comprising;

a jacket interior surface, and

a jacket interior cavity defined by the jacket interior surface wherein the first supply hose, the first return hose, the second supply hose, and the second return hose are disposed in the jacket interior cavity.

2. The cable of claim 1 , further comprising a pilot cable disposed in the jacket interior cavity.

3. The cable of claim 2 , wherein the pilot cable is disposed between the first supply hose, the first return hose, the second supply hose, and the second return hose.

4. The cable of claim 1 , further comprising a plurality of pilot wires disposed in the jacket interior cavity.

5. The cable of claim 1 , further comprising a ground wire disposed in the jacket interior cavity.

6. The cable of claim 1 , wherein the first supply hose, the first return hose, the second supply hose, and the second return hose are adjacent to the jacket interior surface.

7. A cable comprising:

a first supply hose comprising;

a first supply hose interior surface,

a first supply hose interior cavity defined by the first supply hose interior surface, and

a supply conductor being disposed within the first supply hose interior cavity wherein a first supply hose interior space is formed between the supply conductor and the first supply hose interior surface within the first supply hose interior cavity, wherein the first supply hose interior space provides a first supply pathway for first supply hose coolant;

a first return hose comprising;

a first return hose interior surface, and

a first return hose interior cavity defined by the first return hose interior surface, wherein the first return hose interior cavity provides a first return pathway for the first supply hose coolant supplied through the first supply hose interior space by merging the first supply hose to the first return hose at a load;

a second supply hose comprising;

a second supply hose interior surface,

a second supply hose interior cavity defined by the second supply hose interior surface, and

a return conductor being disposed within the second supply hose interior cavity, wherein a second supply hose interior space is formed between the return conductor and the second supply hose interior surface within the second supply hose interior cavity, wherein the second supply hose interior space provides a second supply pathway for second supply hose coolant, and wherein the first supply pathway and the second supply pathway are connected to a main supply pathway through a first conduit bifurcation point;

a second return hose comprising;

a second return hose interior surface, and

a second return hose interior cavity defined by the second return hose interior surface, wherein the second return hose interior cavity provides a second return pathway for the second supply hose coolant supplied through the second supply hose interior space by merging the second supply hose to the second return hose at the load, wherein the first supply hose coolant is supplied by a cooling device and returns to the cooling device via the first return hose, wherein the second supply hose coolant is supplied by the cooling device and returns to the cooling device via the second return hose, and wherein the first return pathway and the second return pathway are connected to a main return pathway through a second conduit bifurcation point; and

a jacket comprising;

a jacket interior surface, and

a jacket interior cavity defined by the jacket interior surface wherein the first supply hose, the first return hose, the second supply hose, and the second return hose are disposed in the jacket interior cavity.

8. The cable of claim 7 , further comprising a pilot cable disposed in the jacket interior cavity.

9. The cable of claim 8 , wherein the pilot cable is disposed between the first supply hose, the first return hose, the second supply hose, and the second return hose.

10. The cable of claim 7 , further comprising a plurality of pilot wires disposed in the jacket interior cavity.

11. The cable of claim 7 , further comprising a ground wire disposed in the jacket interior cavity.

12. The cable of claim 7 , wherein the first supply hose, the first return hose, the second supply hose, and the second return hose are adjacent to the jacket interior surface.
