Objective To design a lithium-ion battery pack thermal management module suitable for high-cold environment to reduce the impact of low temperature on battery performance and extend its service life. Methods The electrical characteristics of lithium-ion battery in high-cold environment were obtained through experiments. The functional requirements of thermal management module under high-cold conditions could were determined. Based on this, the hardware design and strategy development of the thermal management module was carried out. And the experimental platform for low temperature test of battery was built to verify its feasibility. Results When the surface temperature of the battery was preheated to 0 ℃ at an ambient temperature of-35 ℃ and the battery was discharged at a low rate, the available capacity of the battery might be improved to 34.7% of the rated capacity. And the usable capacity of the battery could be increased by increasing the preheating temperature. Conclusion The thermal management module can effectively manage the lithium-ion battery packs and improve the usable capacity of the polar research ship energy storage system in high-cold environment.
