Thermal Management Techniques for Lithium-Ion Batteries

Electric vehicles have shown great potential in combating climate change and reducing carbon emissions. As a power source for electric vehicles, batteries are greatly affected by temperature in terms of performance and safety. An effective thermal management control system can keep the battery pack temperature in the best working range and improve the driving range of the vehicle. The current mainstream battery thermal management technologies for heat dissipation and insulation of batteries were mainly summarized, including air cooling, liquid cooling, phase change cooling, heat pipe cooling, and battery heating technology. It was proposed that battery thermal management technology should be developed in the direction of intelligent, integrated, combined with machine learning, and able to adjust battery ecological temperature adaptively, and there will be a lot of research space.
