The investigation into enhancing the cooling performance of High-Performance Thermal Management Systems (HPTMS) for lithium-ion batteries during fast charging presents significant advancements in EV battery thermal management.
Furthermore, the research extends its reach into developing a sophisticated battery thermal management system. This system ingeniously incorporates heat pipes alongside a nonlinear model predictive controller (MPC). The synergy of these components yields precise temperature regulation and notable reductions in power consumption.
Compared to natural convection and aluminum plate cooling, heat pipe cooling significantly improves heat dissipation and temperature uniformity due to its high thermal conductivity , . Integrating a flat plate Loop Heat Pipe (LHP) beneath the module in EVs marks a significant advancement in battery thermal management.
The operating process involves the liquid (e.g., silicone oil) heated by the heater flows between the cells by employing the pump, facilitating the transfer of heat from the liquid to the battery. The inlet temperature, heating time, and external ambient temperature of the battery heating system all have an effect on the heat balance performance.
Effectively managing temperature extremes is crucial for ensuring the overall safety and reliability of EV batteries. Addressing safety considerations in BTM involves incorporating thermal management into testing protocols, introducing standards tailored for alpine regions, and emphasizing the importance of the entire battery life cycle .
