Battery performance is affected by the problem of overheating which can cause mechanical damage to the battery and electronic components of the BMS (Battery Management System). With the need for an increase in battery charging time with fast capacity, the internal heat generated by the battery also increases so that the battery pack needs to be equipped with a cooling system. Currently, the cooling system in the battery pack uses a lot of cooling plate, cooling pipe, PCM (Phase Change Material) and cooling fluid. Combining cooling system design based on advantages and disadvantages to produce the best performance was tried using the cooling plate and PCM. The method used is to change the initial design of the battery pack without cooling to a cooling system by making a design and verifying the design. The process of thermal analysis is carried out in the process of charging the battery and removing the battery. The result of the research is the distribution of heat transfer that occurs during the battery charging process and the battery discharge is uniform and the temperature value obtained is the 43,2 °C battery discharge process in the main cooling plate component and the maximum temperature in the charging process is 57,6°C. at BMS. Cooling using a cooling plate and PCM for a closed system is maximized. Keywords: baterai Litium-Ion, Heat Sink, PCM

“…Improvisation in the air cooling BTMS design can help augment the overall performance of the automobile. The design optimization of air cooling BTMS could be accomplished by different arrangements such as modifying the packing arrangement in Parallel, staggered, cross, dense, line, rectangular, square, hexagonal and ringed arrangements [15][16][17][18][19][20] and modifying the air flow channel as tilting the case by 5ᵒ to reduce the air flow drag, arranging the batteries horizontally, using two sided cooling with wide unequally spaced channel, employing reciprocating airflow channel, directing the airflow via thin ducts, baffles, inlet plenum, novel U-Type channel, Z-Type channel and J-Type channels [21][22][23][24][25][26][27][28][29][30][31]. Other innovative and effective modifications include incorporation of vortex generators [32], tapering of manifold and provision of holes for pressure relief and creating a negative pressure gradient in the pack [32][33][34].…”

The transition to electric mobility, owing to their proposition as a solution to the environmental qualms of rising levels of pollution due to the utilization of conventional sources of energy (fossil fuels), has directed the attention of researchers to the main energy storage system of the electric vehicles that is batteries. Due to their efficient peak and average power delivery, batteries are the preferred choice for energy storage. With Lithium-ion chemistry proving to be an efficient battery technology in terms of energy density, specific power, safety, durability, and reduced emissions; the requirements for their optimum operation include a temperature range of 15°C-35°C and a uniform temperature profile, which in turn affects the vehicle performance are a cause of concern. This underscores the importance of a design of an effective battery thermal management system (BTMS). A BTMS is tasked with the maintain a fixed range of temperature throughout the battery operation, thus enhancing its life and efficiency. A variety of BTMS designs have been presented based on different types of medium, power consumption and thermal cycle. The objective of this work is to analyse the different BTMSs for different arrangements of cells in a battery module using CFD and utilize the results of the analysis to propose the optimum, cost-effective, and low maintenance BTMS for enhanced performance of the battery module. The CFD analysis is performed the assessment of the airflow using ANSYS Fluent in the BTMS. The analysis of the air flow through the battery module can give a better insight on changing the packing arrangement of cells and positioning of active or passive thermal management systems.

“…The thermo‐mechanical coupling behavior of a multilayer LIB is evaluated during discharge 17 in which its one‐way coupling and the influence of the deformation on the temperature are neglected. Kang et al 18 developed a thermal analysis model of the battery pack with the forced convection condition, in which thermal radiation was ignored. Yuan 12 developed a multiphysical coupled model among mechanics, exothermicity, short‐circuit, battery, and temperature, which can exhibit the internal circuit caused by the mechanical deformation of LIBs.…”

Summary Thermal instability has severely limited the wide application of the lithium ion batteries. In this work, a thermo‐mechanical coupling model of cylinder lithium‐ion batteries (LIBs) with the thermal radiance effect is developed in generalized plane strain condition, which is two‐way coupling. Then, taking 18 650 LIBs as the object, some numerical calculations are implemented to discuss the impacts of initial temperature, discharge current, heat convection coefficient, thermal emissivity and internal resistance upon the distributions of temperature, radial and hoop stresses during charge or discharge. Numerical results show that the maximum temperature in LIBs will decrease when the initial temperature, discharge current, and internal resistance decrease or heat convection coefficient and the thermal emissivity increase. Finally, two comparisons are made to indicate that (1) the temperature in the coupled model is lower than that in the thermal model and (2) the thermal radiation effect plays a vital role in the temperature and stresses, and it can effectively reduce the temperature.
