- Summary:
- The electric heavy-duty truck has been receiving much attention due to its low carbon emission characteristic. This paper presents the winterized design of thermal management for an electric heavy-duty truck. The changes of important parameters in the modes of rapid heating from a cold start battery, cabin defrosting, and cabin heating in winter are discussed based on water source heat pumps. It takes 1300 seconds to warm the battery to 5°C from an ambient temperature of -10°C. Under the same heat production condition, the proposed water source heat pump can save 28.2% energy comparing with the air source heat pump, the cabin air conditioner air outlet can stay above 40°C for more than 5 minutes, and the cabin temperature can be stabilized at 20°C to meet the heating demand of the crew in winter
