Abstract

One thermal control system for use during electric vehicle battery charging includes a charging station thermally conditioning a fluid and sending the fluid to a vehicle charge inlet. The vehicle charge inlet thermally conditions the fluid and sends the fluid to one of a vehicle thermal loop or a vehicle heat exchanger. Another thermal control system includes a charging station thermally conditioning a fluid and sending the fluid to a vehicle charge inlet. The vehicle charge inlet thermally conditions the fluid and sends the fluid back to the charging station. In another thermal control system, a vehicle thermal loop supplies a fluid at a first temperature to a vehicle charge inlet. The vehicle charge inlet thermally conditions the fluid to a second temperature and returns the fluid to the vehicle thermal loop.

First claim

What is claimed is:

1. A thermal control system, comprising;
a charging station fluid source configured to supply a fluid at a first temperature; and
a charging station connector configured to:
supply an electrical charge to a vehicle charge inlet;
receive the fluid at the first temperature;
thermally condition the fluid to a second temperature, wherein the second temperature is cooler than the first temperature; and
send the fluid at the second temperature to the vehicle charge inlet, wherein the vehicle charge inlet is configured to:
receive the fluid at the second temperature;
thermally condition the fluid to a third temperature; and
send the fluid at the third temperature to the charging station connector.

2. The system of claim 1 , wherein the third temperature is warmer than the second temperature based on the fluid cooling the vehicle charge inlet.

3. The system of claim 1 , wherein the second temperature is cooler than the first temperature based on the fluid warming the charging station connector.

4. The system of claim 1 , wherein the third temperature is cooler than the second temperature based on the fluid warming the vehicle charge inlet.

5. The system of claim 1 , wherein the second temperature is cooler than the first temperature prior to the charging station connector supplying the electrical charge to the vehicle charge inlet.

6. The system of claim 5 , wherein the charging station fluid source is configured to supply the fluid at a fourth temperature lower than the first temperature while the charging station connector supplies the electrical charge to the vehicle charge inlet.

7. The system of claim 1 , wherein the fluid at the second temperature and the fluid at the third temperature travel along separate conduits between the charging station connector and the vehicle charge inlet.

8. A thermal control system, comprising;
a vehicle thermal loop configured to supply a first fluid at a first temperature, wherein the first fluid is a liquid media; and
a vehicle charge inlet configured to:
receive the first fluid at the first temperature from the vehicle thermal loop;
thermally condition the first fluid to a second temperature using a second fluid supplied by a charging station connector from a charging station fluid source of a charging station configured to supply an electrical charge to the vehicle charge inlet,

wherein the second fluid is a gaseous media; and
send the first fluid at the second temperature to the vehicle thermal loop.

9. The system of claim 8 , wherein the second fluid is isolated from the first fluid.

10. The system of claim 8 , wherein the second temperature is warmer than the first temperature prior to the charging station connector supplying an electrical charge to the vehicle charge inlet based on the second fluid warming the charging station connector and the vehicle charge inlet.

11. The system of claim 10 , wherein the second temperature is cooler than the first temperature while the charging station connector supplies the electrical charge to the vehicle charge inlet based on the second fluid cooling the charging station connector and the vehicle charge inlet.

12. The system of claim 8 , wherein the charging station fluid source supplies the second fluid at a third temperature, and wherein the charging station connector receives the second fluid at the third temperature, thermally conditions the second fluid to a fourth temperature, and sends the second fluid at the fourth temperature to the charging station fluid source.

13. The system of claim 12 , wherein the fourth temperature is warmer than the third temperature and the second temperature is warmer than the first temperature.

14. The system of claim 12 , wherein the fourth temperature is cooler than the third temperature.

15. The system of claim 12 , wherein the second fluid at the third temperature and the second fluid at the fourth temperature travel along separate conduits between the charging station fluid source and the charging station connector.

16. A thermal control system, comprising;
a vehicle charge inlet configured to:
receive fluid at a first temperature from a charging station connector;
thermally condition the fluid to a second temperature; and
send the fluid at the second temperature to the charging station connector, wherein the second temperature is cooler than the first temperature based on the fluid warming the vehicle charge inlet;

wherein the charging station connecter is configured to:
receive the fluid from a charging station fluid source;
send the fluid at the first temperature to the vehicle charge inlet; and
supply an electrical charge to the vehicle charge inlet.

17. The system of claim 16 , wherein the vehicle charge inlet is configured to receive the fluid at the first temperature before the charging station connector supplies the electrical charge to the vehicle charge inlet.

18. The system of claim 17 , wherein the charging station connector is further configured to send the fluid at a third temperature that is less than the first temperature while the charging station connector supplies the electrical charge to the vehicle charge inlet.

19. The system of claim 16 , wherein the fluid at the first temperature and the fluid at the second temperature travel along separate conduits between the charging station connector and the vehicle charge inlet.

20. The system of claim 18 , wherein the third temperature is less than the second temperature based on the fluid cooling the vehicle charge inlet while the charging station connector supplies the electrical charge to the vehicle charge inlet.
