Abstract

A system and a method for supplying electrical energy to high-power vehicle braking resistors to generate heat for supplemental heating. Supplemental heat is transferred from the braking resistors to a desired use by means of circulating liquid or air, and heat exchangers at the desired location. The supplemental heat can be supplied external to the vehicle by circulating liquid or air and using appropriate external heat exchangers.

Claims

1. A method of supplying supplemental heating from one or more braking resistors of a vehicle to a separate location, comprising:

supplying electrical energy to the one or more braking resistors so as to cause heat energy to be generated there from;

transferring the heat energy of the one or more braking resistors by a circulating fluid medium to the separate location; and

extracting the transferred heat energy in the circulating fluid medium for use at the separate location.

2. The method of claim 1, wherein the one or more braking resistors are part of an electromagnetic braking system for a vehicle.

3. The method of claim 2, wherein the vehicle is a heavy-duty vehicle with a gross weight of over 10,000 pounds.

4. The method of claim 1, further including an electrical energy supply to supply electrical energy to the one or more braking resistors, and the electrical energy supply to the braking resistor is at least one of an engine/generator, energy storage, and an electromagnetic motor or generator operating in a braking regeneration mode.

5. The method of claim 4, wherein the energy storage is at least one of a battery pack, an ultracapacitor pack, and a flywheel.

6. The method of claim 1, wherein the circulating fluid medium is a circulating liquid coolant.

7. The method of claim 6, wherein the circulating liquid coolant also circulates through an engine and is used to warm a cold engine.

8. The method of claim 6, wherein extracting the transferred heat energy includes passing the liquid coolant through a liquid-to-air heat exchanger radiator.

9. The method of claim 8, where the heat exchanger radiator is used as a source of warm air to circulate into a passenger compartment of a truck or a bus.

10. The method of claim 1, wherein the braking resistors are air cooled and the cooling air is used as a source of warm air to circulate into a passenger compartment of a truck or a bus.

11. The method of claim 6, further including circulating the liquid coolant off board, external to the vehicle, to supply supplemental heat for heating a liquid or gas external to the vehicle.

12. The method of claim 1, wherein the vehicle is at least one of a hybrid-electric and an all-electric driven vehicle.

13. The method of claim 6, wherein extracting the transferred heat energy includes passing the liquid coolant through a primary liquid-to-secondary liquid heat exchanger to heat the secondary liquid.

14. The method of claim 13, wherein the secondary liquid is water for use inside the vehicle.

15. A system for supplying supplemental heating from braking resistors of a vehicle to a separate location, comprising:

means for supplying electrical energy to one or more braking resistor heating elements, the electrical energy converted to heat energy by the one or more braking resistor heating elements;

means for transferring the heat energy of the one or more braking resistor heating elements by a circulating fluid medium to a separate location; and

means for extracting the transferred heat energy in the circulating fluid medium for use at the separate location.

16. The system of claim 15, wherein the one or more braking resistors are part of an electromagnetic braking system for a vehicle.

17. The system of claim 15, wherein the vehicle is a heavy-duty vehicle with a gross weight of over 10,000 pounds.

18. The system of claim 15, further including an electrical energy supply to supply electrical energy to the one or more braking resistors, and the electrical energy supply to the braking resistor is at least one of an engine/generator, energy storage, and an electromagnetic motor or generator operating in a braking regeneration mode.

19. The system of claim 18, wherein the energy storage is at least one of a battery pack, an ultracapacitor pack, and a flywheel.

20. The system of claim 15, wherein the circulating fluid medium is a circulating liquid coolant.

21. The system of claim 20, wherein the circulating liquid coolant circulates through an engine and is used to warm a cold engine.
