Lithium-ion battery packs' discharging results in significant heat generation, which leads to safety issues and negative impact during the application of electric vehicles. Previous studies focused more on the configurations and design of cell packs/modules with a cooling system to control the battery cell's temperature. However, temperature differences are more difficult to control to ensure thermal uniformity. Maximum pressure is a significant parameter that affects energy consumption and the cost of the cooling system. This study proposed a comprehensive approach to design an efficient mist cooling system, which considered both maximum temperature and temperature standard deviation. This design method generates candidate design points by Latin Hypercubes Sampling and design of experiments (DOEs); effects of some significant parameters of the cooling structure on the cooling efficiency are evaluated by sensitivity analysis. Surrogate models are then selected and optimized by the multi-objective optimization approach to acquire an optimal scheme of the mist cooling structure. The optimized results showed that the optimized mist cooling battery module has better thermal performance with a lower cost. This approach can be used in the battery pack design process to control the temperature rise and temperature distribution, and energy consumption of the cooling system.

Summary In an electric vehicle, energy storage is in the form of electrochemical batteries, which are prone to thermal runaway and capacity fading if not maintained below safe temperature limits. An efficient battery cooling system is necessary for safer usage of electric cars during their life cycle. The current work presents a novel design that allows the coupling of liquid channels to a phase change material container in cylindrical batteries. The channeling approach allows heat dissipation from the phase change material container to both circulating media and convecting air. The design also helps to operate the cooling system without the circulation of liquid media in case of low ambient conditions. The comparison of the proposed system with a noncoupled liquid channel system is also presented to underline the merits of the system. The cooling media at a supply temperature of 30°C and the flow rate of 30 mL/min is adequate during the high ambient temperature of 40°C. The coupling of liquid channels to phase channel containers resulted in lowering the battery temperature well below 41.2°C even at an extremely high ambient temperature of 40°C.

Summary A battery thermal management system (BTMS) is essential for the longevity and thermal safety characteristics of batteries. In this study, a cooling system based on a thermoelectric cooling (TEC) unit is designed to improve the heat performance of a battery pack. The varied increase in cell temperatures under natural convection, liquid cooling, and TEC was compared to verify its feasibility, after which the authors carried out a current condition optimization strategy. The discharge performance of the battery at a discharge rate of 1C is studied under the conditions of equivalent, differential, and sectional currents. Under the equivalent current condition, it was determined that at the end of discharge, the temperature increase of the battery can be controlled at approximately 3.5°C when the working current of the semiconductor cooling unit is at 3.5 A compared to 0.5 A. When the differential current condition was adopted, the temperature difference of the battery pack was enhanced and maintained within a temperature of 5°C. Piecewise current was proposed based on the performance evaluation of BTMS in the equivalent and differential current conditions. The increase in temperature of the battery pack was just 1.5°C, and the values of the temperature difference in the battery pack and single battery remained within 5°C. Compared with the differential current condition, the maximum temperature increased only by 1°C at the discharge end, with its power consumption reduced by 63.4%.
