This article explores various techniques to optimize the operation of lithium-ion batteries in electric vehicles (EVs). Lithium-ion batteries exhibit their highest performance within a temperature range of 16 to 25°C, while maintaining functionality within a broader range of 0 to 35°C. The article focuses on investigating different cooling methods, including liquid jackets, cold plates, microchannel cooling plates, serpentine channel cooling plates, and coolant immersion, to regulate the temperature of lithium-ion battery packs. The effectiveness of the thermal management system in maintaining the battery temperature within the specified operating range is thoroughly examined through experimental and simulation results. The findings reveal that these cooling techniques successfully control the temperature under various discharge loads. The recorded maximum temperature (Tmax) is 33.82°C, with a delta Tmax (ΔTmax) of 3.18°C at an ambient temperature of 26.5°C. Maintaining an appropriate temperature range is vital for optimizing the performance of lithium-ion batteries in EVs. The results provide valuable insights and pave the way for future research to enhance the thermal management system for lithium-ion battery packs in EVs. This article highlights the significance of maintaining the temperature range of lithium-ion batteries in EVs to ensure optimal performance. The explored techniques and methods present potential avenues for achieving this objective, and the findings serve as a reference for future studies aimed at improving the thermal management system for lithium-ion battery packs in EVs.
