摘要： 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.

摘要： An electric vehicle has a thermal management system that comprises a common radiator, a brake resistor loop, and an electric power source loop. The brake resistor loop comprises a brake resistor and a brake resistor controller that are coupled to the common radiator. The electric power source loop comprises an electric power source coupled to the common radiator. When the brake resistor loop is determined to be in operation, the common radiator is utilized by the brake resistor loop to absorb heat generated by the brake resistor loop. When the brake resistor loop is determined to not be in operation, the common radiator is utilized by the electric power source to absorb heat generated by the electric power source loop.

摘要： An integrated thermal management system for a fuel cell electric vehicle is disclosed. The integrated thermal management system includes a fuel cell system, a brake resistor, a fuel cell coolant loop that includes a fuel cell radiator thermally and fluidly coupled to the fuel cell system, a brake resistor coolant loop that includes a brake resistor radiator thermally and fluidly coupled to the brake resistor, and a heat exchanger loop that includes a coolant-coolant heat exchanger thermally and fluidly coupled to the fuel cell coolant loop and the brake resistor coolant loop. In a fuel cell cooling operating mode, heat is transferred from the fuel cell system to an ambient environment through the fuel cell radiator and the brake resistor radiator.
