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 electric vehicle includes a first heat exchanger positioned adjacent to a front of the electric vehicle and configured to transfer heat generated from a first heat generating system to an ambient environment. The electric vehicle may further include a second heat exchanger positioned adjacent to a rear of the electric vehicle and configured to transfer heat generated from a second heat generating system to the ambient environment, and an air supply plenum positioned longitudinally between the first heat exchanger and the second heat exchanger and in fluid communication with the ambient environment. The air supply plenum may define a cooling air pathway extending between the ambient environment and the second heat exchanger. The air supply plenum may isolate air flowing through the cooling air pathway from air circulating within the electric vehicle.
