“…Various EV thermal management systems can generally be classified into three categories based on the fluid and heat transfer mechanism, that is, passive, active, and hybrid active-passive methods (Ianniciello et al, 2017;Kim et al, 2019). The passive system relies solely on thermodynamics without any electrical power requirement, such as using a heat sink or Phase Change Materials (Amin et al, 2018;Budiman et al, 2020Budiman et al, , 2022Chen et al, 2014). Such a passive system is considerably more straightforward and economical in its design.…”

Streamwise development of counter-rotating vortices induced by three different types of chevron Vortex Generators (VGs) placed upstream an Electric Vehicles (EV) dummy battery module is experimentally visualized using a smoke-wire method. From the single chevron reference case, the mushroom-like vortices do not collapse until passing the module. When more chevrons are used in line, the vortices become more prominent. It can also be observed that the vortex sizes and shapes are significantly influenced by the spanwise base length of the chevron. The induced vortices from all three VGs suggest a potential heat transfer augmentation for the EV battery module application.

“…The placement of such tubes is carefully designed, calculating its heat transfer effectiveness as well as repair efforts required in the case of leakage. The experimental setup and battery configurations have been previously reported (Budiman et al, 2022a). Three different organic PCMs were selected: paraffin, lauric acid, and caprylone (all purchased from Sigma Aldrich, Singapore).…”

The development of batteries for Electric Vehicles (EVs) cannot be separated from the thermal management aspect. In this manuscript, various design optimisation attempts utilising Phase Change Materials (PCMs) and Vortex Generators (VGs) to improve the heat dissipation from the EV battery module are performed and analysed. Three different organic PCMs are considered, and their latent heat absorption profile suggests different potential solutions. Paraffin, one of the most popularly used PCMs, could have a better thermal performance than lauric acid and caprylone for up to a 24.9% temperature reduction, despite its considerably lower peak latent heat capacity. However, its mechanical strength is also significantly lower in a PCM-resin composite; hence, it requires a certain reinforcement material in its application. Meanwhile, the use of VGs is qualitatively analysed by means of wind tunnel smoke visualisation. A simple yet effective VG could induce streamwise vortexes that could be attributed to mass and heat transfer augmentation.

“…The researchers use paraffin wax as the base material along with additives to increase its thermal conductivity. [21][22][23][24][25] They numerically analyzed the BTM system using paraffin wax RT-42 as PCM material with different thicknesses varying from 1 mm to 7 mm with an increment of 1 mm on 18 650 Li-ion cells. It was discovered that RT-42 must be at least 3 mm thick to keep the battery temperature below 50 °C at a 3 C discharge rate.…”

Lithium‐Ion Battery Thermal Management Techniques and Their Current Readiness Level

2022

View full text Add to dashboard Cite

The lithium‐ion battery (LiB) is currently an essential part of electric vehicles (EVs). The popularity of LiBs among EV manufacturers is because of their long life, fewer memory effects, high specific energy density, and lightweight. However, temperature affects the LiB life and performance to a great extent. The burden on battery thermal management (BTM) is significantly increased by the need to increase battery capacity and decrease the battery charging time. Hence, reliable and effective BTM is the need of the hour. Herein, the current status of different battery cooling techniques has been discussed along with their merits and demerits. The main objective of this paper is to inform the readers and give them a clear understanding of various cooling techniques and their current status and highlight any novel approaches being used by the researchers to improve these cooling techniques. Future needs and opportunities in this field have also been discussed.
