“…Liquid coolant can be circulated through pipes within the system, and the convective heat transfer between the liquid and the system components is the main cooling mechanism 43 . Yang et al 44 studied the impact of flow path on a parallel liquid cooling TMS, analyzed the heat dissipation performance under different discharge currents, and proposed an optimization strategy to improve the cooling efficiency for the TMS.…”

The rapid growth of transportation demand has been enlarged strongly which has promoted electric vehicles powered by lithium-ion batteries. However, the inconsistencies within the battery pack will deteriorate over the lifecycle and affect the performance of electric vehicles. Therefore, various thermal management systems and equalization systems have been applied in battery management system to deal with the inconsistencies, extend battery service life, and improve safety performance. This review summarizes the origination of inconsistency within lithium-ion batteries from production to usage process, and then introduces the classification methods and application scenarios of the balance management system in detail. Based on the circuit topology, equalization systems can be classified into passive and active topologies. Active topologies

Structural and flow parameters have a substantial effect on the thermal and hydraulic performance of a lithium-ion battery and cooling system. In this study, a computational fluid dynamics model is developed for double coldplate based liquid cooling for a 20 Ah lithium-ion pouch cell, and then validated based on experimental data. An orthogonal test consisting of single factor and multi-factor analysis is designed to obtain the sensitivity of four factors, including the inlet coolant temperature, inlet coolant volume flow rate, number of cooling channels, and maximum channel width that influence the thermal behavior of the pouch cell. The multi-objective optimization for minimizing maximum temperature, maximum temperature difference and average pressure drop using genetic algorithm is conducted subjected to constraints of operating conditions for optimum battery performance. Based on the multiobjective optimization, the obtained minimized values for maximum temperature (T max), maximum temperature difference (ΔT max) and average pressure drop (ΔP avg) are 25.25 C, 0.22 C and 48.76 kPa. The minimized objective functions are obtained at the inlet coolant temperature of 25 C, inlet coolant volume flow rate of 240 mL/min, number of cooling channel of 10 and maximum channel width of 1.70 mm.

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.
