Indirect thermal management system for electric vehicle and electric vehicle including same

An indirect thermal management system for an electric vehicle including a battery pack, at least one driven wheel, and at least one electric motor in electrical communication with the battery pack and configured to drive the driven wheel, the indirect thermal management system comprising:

• a first fuel cell unit that includes a fuel cell stack and a balance of plant;
• a first heat exchanger in fluid communication with the fuel cell stack and isolated from the balance of plant;
• and
• a first high temperature cooling circuit that is isolated from the first fuel cell unit such that coolant flowing through the fuel cell stack of the first fuel cell unit is isolated from coolant flowing through the first high temperature cooling circuit, the first high temperature cooling circuit includes:
• a first load resistor in fluid communication with the first heat exchanger, the first load resistor is configured to convert electrical energy into heat;
• a first radiator in fluid communication with the first load resistor, the first radiator is configured to be in fluid communication with ambient air outside of the electric vehicle;
• and
• a first pump in fluid communication with the first radiator and the first heat exchanger, and configured to circulate coolant among the first heat exchanger, the first load resistor, and the first radiator.
