Abstract: To improve the thermal performance of lithium-ion power batteries in low-temperature environment,this paper proposes a low-temperature preheating module structure for power battery thermal management based on single beam heat pipe.On the basis of experimental verification of the heat production model of single cell,the effects of the preheating ways for the evaporation section of the heat pipe,the inlet temperature of the coolant,and the ambient temperature on the preheating performance of the battery module are researched through numerical calculation.
Key words: power battery; thermal management; low-temperature preheating
