Abstract
Official abstract text for this publication.
A vehicle has a thermal management system that comprises an electric power source loop comprising at least one battery. The thermal management system further comprises a heating component thermally coupled to the electric power source loop. When an ambient temperature is less than a first threshold, the heating component pre-heats the at least one battery. In exemplary embodiments, the heating component includes at least one brake resistor that is coupled to the electric power source loop.
First claim
Opening claim text (preview).
What is claimed is: 1. A thermal management system for a vehicle, comprising: an electric power source loop comprising at least one battery; a brake resistor loop, wherein the brake resistor loop comprises at least one brake resistor; and a shut-off valve, wherein the shut-off valve is coupled to the electric power source loop and the brake resistor loop, wherein, when an ambient temperature is less than a first threshold, the shut-off valve thermally couples the electric power source loop to the brake resistor loop and a first valve thermally couples the brake resistor loop to the electric power source loop to pre-heat the at least one battery. 2. The thermal management system of claim 1 , wherein the first threshold is less than 15 degrees Celsius. 3. The thermal management system of claim 1 , wherein the first valve is a 4-way valve. 4. The thermal management system of claim 1 , further comprising: an alternate cooling system thermally coupled to the electric power source loop, wherein, when the brake resistor loop and the electric power source loop are in operation at the same time, the alternate cooling system absorbs heat generated by the electric power source loop. 5. The thermal management system of claim 4 , wherein the alternate cooling system comprises a refrigeration system. 6. The thermal management system of claim 1 , wherein the electric power source loop comprises at least three batteries. 7. The thermal management system of claim 6 , wherein each battery is thermally coupled in parallel with the other at least two batteries.
