摘要: The present disclosure provides a powertrain thermal management system for managing thermal loads in the powertrain of an electric vehicle. The system may comprise a first coolant flow path comprising a flow split valve upstream of a first DC-DC converter, a second coolant flow path comprising a first electric motor, a third coolant flow path comprising a second electric motor, a bypass valve positioned downstream of the first DC-DC converter, the first electric motor, and the second electric motor, and a radiator positioned one of directly upstream or directly downstream of the bypass valve. The first coolant flow path, the second coolant flow path, and the third coolant flow path are fluidly connected in parallel.

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.
