“…Battery thermal management systems are used in EVs and HEVs to remove excessive heat from the batteries. The reported cooling techniques in the literature mainly include air cooling, [11] liquid cooling, [12] phase-change material (PCM) cooling, [13,14] and their combinations. [15,16] Air cooling is the most commonly used one in the small-scale battery packs due to its low cost, simple configuration, and convenient maintenance.…”

The application of the minichannel cold plate in a cylindrical battery module encounters the problem of poor heat transfer capability as it cannot match well with the curved surfaces of the cylindrical batteries. Herein, design optimization of a minichannel cold plate is performed to enhance its heat dissipation performance in the cylindrical battery module. In‐depth analyses are made on the thermal behavior of a cylindrical battery module with minichannel cold plates. Influences of different cold plate design parameters, including the size and position of the heat transfer interface between the batteries and the cold plates, the cold plate material, and the cold plate thickness, are examined and compared under various coolant velocities. The results highlight the significance of cold plate design in achieving a high‐performance cooling system for the cylindrical battery module. Based on the results, some general rules are set for the design of minichannel cold plates in the cylindrical battery module, which can provide useful guidance for the future development of minichannel cold plates.

“…Furthermore, air cooling requires a large amount of air, making the system larger in volume [11]. PCM has low thermal conductivity and is prone to thermal saturation [12,13]. Liquid cooling offers higher specific heat capacity, faster mass flow, and better temperature uniformity compared with air cooling.…”

The heat dissipation capability of the battery thermal management system (BTMS) is a prerequisite for the safe and normal work of the battery. Currently, many researchers have designed and studied the structure of BTMS to better control the battery temperature in a specific range and to obtain better temperature uniformity. This allows the battery to work safely and efficiently while extending its life. As a result, BTMS has been a hot topic of research. This work investigates the impact of pin-fins on the heat dissipation capability of the BTMS using the computational fluid dynamics (CFD) approach, designs several BTMS schemes with different pin-fin structures, simulates all schemes for fluid-structure interaction, and examines the impact of different distribution, number, and shape of pin-fins on heat dissipation capability and pressure drop. Analyzing the effect of cooling plates with different pin-fins on the thermal capability of the BTMS can provide a basis for the structural design of this BTMS with pin-fin cooling plates. The findings demonstrate that the distribution and quantity of pin-fin shapes might affect heat dissipation. The square-section pin-fins offer better heat dissipation than other pin-fin shapes. As the pin-fins number increases, the maximum battery temperature decreases, but the pressure drop increases. It has been observed that uniform pin-fin distribution has a superior heat dissipation effect than other pin-fin distribution schemes. In summary, the cooling plate with a uniform distribution of 3 × 6 square section pin-fins has better heat dissipation capability and less power consumption, with a maximum battery temperature of 306.19 K, an average temperature of 304.20 K, a temperature difference of 5.18 K, and a pressure drop of 99.29 Pa.

“…[20][21][22][23] The phase-change enthalpy, temperature, and rate are important parameters that affect the endothermic effect. 24 Polymers that undergo a sol-gel transition involve a similar thermal switch, in which the polymer undergoes a sol-gel transition when the ambient temperature reaches the sol-gel transition temperature; 8,[25][26][27] however, they have an additional advantage that is the sol-gel transition hinders or even eliminates ion transport inside the ESDs, thus switching off the current flow and preventing further heat accumulation caused by continued work under overheating conditions. 8,28,29 Thermal melting polymers operate by releasing a functional substance such as a flame retardant or electrolyte poisons when the temperature of the ESDs reaches the melting point of the polymer, thereby preventing thermal runaway.…”
