Research on the heat transfer characteristics of lithium-ion batteries is of great significance to the thermal management system of electric vehicles. The electrodes of lithium-ion batteries are composed of porous materials, and thus the heat conduction of the battery is not a standard form of diffusion. The traditional heat conduction model is not suitable for lithium-ion batteries. In this paper, a fractional heat conduction model is used to study the heat transfer properties of lithium-ion batteries. Firstly, the heat conduction model of the battery is established based on the fractional calculus theory. Then, the temperature characteristic test was carried out to collect the temperature of the battery in various operating environments. Finally, the temperature calculated by the fractional heat conduction model was compared with the measured temperature. The results show that the accuracy of fractional heat conduction model is higher than that of traditional heat conduction model. The fractional heat conduction model can well simulate the transient temperature field of the battery. The fractional heat conduction model can be used to monitor the temperature of the battery, so as to ensure the safety and stability of the battery performance.

“…The reason was explained that the heat conduction path introduced by branch structure expanded the contact area, thereby improving BTMS cooling efficiency. Choudhari et al [ 73 ] compared the effects of fin shapes on single battery cooling, including rectangle, triangle, trapezoid, I shape, and T shape. Simulation results confirmed that the fin with I shape exhibited best performance at 3 C discharge rate, which reduced maximum battery temperature and temperature difference 6.4 and 1.58 °C, respectively.…”

With the rapid development of electric vehicles (EVs), thermal safety issues have become increasingly prominent. In the charging and discharging process, a proper battery thermal management system (BTMS) can control the temperature of the power battery pack, which is essential to ensure the performance and safety of EVs. Among various cooling technologies, phase change material (PCM) cooling is widely used in BTMS due to its excellent characteristics, such as simple structure, good cooling effect, and no extra energy consumption. Herein, the research progress of PCM on BTMS is reviewed, including the overview of PCMs, the studies of single PCM‐based BTMS, and the development of hybrid PCM‐based BTMS. The results have found that the cooling performance of PCM‐based BTMS is determined by excellent PCM properties and suitable BTMS structure. In addition, the fin‐enhanced structure and active phase change slurry (PCS) can effectively improve the reliability and flexibility of BTMS applications. The hybrid BTMS consisting of PCM and other cooling technology can promote the heat dissipation of PCM, which helps to solve PCM heat saturation and further reduce the battery temperature. Finally, insufficient studies in current research are pointed out, and a future development direction is also reported.

The batteries have been continuously for obtaining the high voltage platform and high density of energy with long lifecycle. The operating temperature of the battery cell has a significant effect on the thermal performance. This paper aims to consider the 18 650-type lithium-ion battery pack's thermal characteristics with the thermoelectric module using ferrofluid as a coolant. The experiment apparatus is test to determine the lithium-ion battery pack's temperature distributions. Effects of the relevant parameters; hot and cold side flow rates (0.03-0.05 m 3 /hr), supplied voltage through thermoelectric (8-12 V), coolant types (De-ionized water and ferrofluid), and ferrofluid concentrations (0.005%-0.015% by volume) on the battery pack's cooling performance are considered. It is found that the thermoelectric cooling system significantly affects the battery pack cooling and gives the temperature of battery below 30 C.
