“…Numerous cooling strategies have been suggested for BTMS. These can be classified as: air cooling (Fan et al , 2019; Sharma and Prabhakar, 2021; Zhou et al , 2019), liquid cooling (Chen et al , 2021; Fan et al , 2022; Jang et al , 2022; Monika and Datta, 2022), cooling by phase change material (PCM) (Choudhari et al , 2021; Lv et al , 2020; Siddique et al , 2018), heat pipe cooling (Gan et al , 2020; Liang et al , 2018) or hybrids of these (Wu et al , 2022; Zhang et al , 2022a, 2022b). For the air cooling, air is the cooling medium.…”

Purpose The purpose of this study is to design a new type of cold plate to improve the thermal performance of liquid-cooled thermal management system of lithium-ion batteries. Design/methodology/approach A cold plate with leaf type channels is proposed to enhance the cooling performance. Effects of the leaf type channel parameters (i.e. channel angle 20°, 40°, 60°, 80°; coolant mass flow rate 0.25 × 10–3, 0.50 × 10–3, 0.75 × 10–3, 1.00 × 10–3, 1.25 × 10–3 kg·s−1; channel number 1, 3, 5, 7) on the performance are numerically investigated by using a 3D mathematical model. Findings Compared to the traditional I type channels, the leaf type channels have better cooling performance. It is found that the battery temperature variation and channel pressure drop are decreased with decreasing channel angle and increasing channel number. In addition, the cooling performance can be improved by increasing the coolant mass flow rate. Practical implications This study can provide guidance for the development of novel effective cold plates. Originality/value The design of cold plates with leaf type channels can be used in liquid-cooled thermal management system to reduce the battery temperature difference.

“…For battery packs operating under high temperature and high power conditions, relying solely on active cooling would require the active cooling method to constantly work and dissipate heat to ensure safety, resulting in a certain amount of energy loss [7,14,15]. On the other hand, using passive cooling alone is insufficient for effectively and rapidly removing heat from the battery pack at high-temperature and high-current environments [16][17][18][19].…”

As electric vehicles (EVs) gain market dominance, ensuring safety during the battery usage is crucial. This paper presents a new thermal management approach to address the battery heat accumulation challenge through a novel combination of composite phase change material (CPCM) with liquid cooling systems. An optimised hybrid cooling model is developed to evaluate the proposed battery thermal management system (BTMS) under high-temperature and high-power conditions. Benchmark studies are conducted to assess the impact of inlet position, inlet flow rate, and flow channel distribution on the cooling performance to achieve a uniform temperature distribution within the battery. The optimised BTMS, consisting of a five-cell battery pack, demonstrates a maximum temperature of 41.15 °C and a temperature difference of 4.89 °C in a operating condition at 36 °C with a discharge rate of 3 C. The BTMS outperforms the initial model, reducing the maximum temperature by 1.5%, temperature difference by 5%, and liquid fraction by 13%, with a slight (1.3%) increase in weight. The cooling performance is most efficient at a liquid flow rate of 0.1 m/s, minimising energy consumption. The proposed BTMS with CPCM-3 is also sufficient enough to keep the battery pack under a thermal runaway event. Overall, the theoretical simulation highlights the BTMS’s ability to effectively control battery temperatures and temperature differences, ensuring safe operation during high-temperature and high-power conditions in practical EV usage.
