Abstract

Improved thermal energy storage materials, devices and systems employing the same and related methods. The thermal energy storage material may be employed in a heater module capable of generating and storing heat. The thermal energy storage materials may include a phase change material that includes a metal-containing compound. The thermal energy storage materials may be encapsulated. Preferably the heater module includes an electric heater and/or a fan.

First claim

What is claimed is:

1. A heater module for a transportation vehicle wherein the heater module comprises:
a) an insulated container;
b) a thermal energy storage material in the insulated container;
c) an electric heater for heating the thermal energy storage material so that the thermal energy storage material undergoes a solid to liquid phase transition; and
d) a means for transferring heat from the insulated container to at least one remotely located component of the motor vehicle external of the insulated container;
such that the heater module provides heat to the at least one remotely located component of the vehicle, during operation of the vehicle, from stored heat in the thermal energy storage material derived from the phase transition.

2. The heater module of claim 1 , wherein the at least one remotely located component of the motor vehicle is a passenger compartment and the means for transferring heat from the housing into the passenger compartment comprises a duct, and a fan.

3. The heater module of claim 1 , module wherein the thermal energy storage material has a liquidus temperature of at least about 40° C.; and exhibits a heat storage density from 200° C. to about 50° C. (HSD 200,50 ) of at least about 0.5 megajoules/liter.

4. The heater module of claim 3 , wherein the thermal energy storage material includes lithium ions.

5. The heater module of claim 4 , wherein the thermal energy storage material includes nitrite and or nitrate ions.

6. The heater module of claim 3 wherein the electric heater is in thermally conducting relation to the insulated container.

7. The heater module of claim 3 , wherein the electric heater is in the insulated container.

8. The heater module of claim 7 , wherein the thermal energy storage material has a liquidus temperature of at least about 85° C.; and exhibits a heat storage density from 300° C. to about 80° C. (HSD 300,80 ) of at least about 1 megajoules/liter.

9. The heater module of claim 8 , wherein the thermal energy storage material is contained in a blister pack.

10. The heater module of claim 8 , wherein the at least one remotely located component of the motor vehicle is a passenger compartment and the means for transferring heat from the housing into the passenger compartment comprises a duct, and a fan.

11. The heater module of claim 10 wherein the thermal energy storage material stores heat and subsequently releases the heat, wherein the heat that is stored and subsequently released is derived from energy liberated prior to an operation event involving engine startup of the vehicle.

12. The heater module of claim 11 , wherein the thermal energy storage material stores heat and subsequently releases the heat, wherein the heat that is stored and subsequently released is derived from energy from a source outside of the vehicle.

13. The heater module of claim 12 , wherein the heat that is stored and subsequently released is derived from energy liberated prior to the operation of a powertrain of the vehicle.

14. The heater module of claim 3 , wherein the at least one remotely located component of the motor vehicle is a passenger compartment and the means for transferring heat from the housing into the passenger compartment comprises a duct, and a fan.

15. The heater module of claim 14 , wherein the means for transferring heat from the housing into a passenger compartment of the motor vehicle comprises a heat transfer fluid, wherein the heat transfer fluid is air.

16. The heater module of claim 14 , wherein the heater module is located in an A-pillar, a B-pillar, a door panel, or a rear quarter panel.

17. The heater module of claim 16 , wherein the motor vehicle relies for its powertrain upon power battery power, power from a fuel cell, or any combination thereof.

18. The heater module of claim 3 , wherein the thermal energy storage material is contained in at least one array portion between two opposing plies of metal foil.

19. The heater module of claim 3 , wherein the motor vehicle is a plug-in vehicle that derives its primary form of energy from an electrical source external of the vehicle.
