Optimization Design Study of Thermal Management System for Lithiumion Batteries

The study focuses on enhancing the thermal efficiency, economy, and safety of lithium-ion battery thermal management systems using an advanced optimization approach. This approach includes improving thermal management material conductivity, refining heat dissipation designs, and integrating modular structures with intelligent controls. Several strategies were tested through simulations and experiments, involving phase change materials, heat pipes, and liquid cooling systems. Results indicate that these technologies substantially boost temperature management and uniformity, prevent thermal runaway, and increase system safety. This suggests that such innovations significantly benefit the longevity and safety of batteries in electric vehicles and portable devices.
