“…The formulas for calculating the estimated value of the test indicator are as follows: The comprehensive balance method was employed to conduct the optimal solution analysis. The formulas for calculating the estimated value of the test indicator are as follows: (14) where µ is the estimated value of mathematical expectation in the experimental data, a k (k = 1, 2, 3, 4) is the effect of factor A (FHP number) corresponding to level k, b m (m = 1, 2, 3, 4) is the effect of factor B (coolant temperature) corresponding to level m, and c n (n = 1, 2, 3, 4) is the effect of factor C (coolant pipe number) corresponding to level n.…”

A large-capacity prismatic lithium-ion battery thermal management system (BTMS) combining composite phase change material (CPCM), a flat heat pipe (FHP), and liquid cooling is proposed. The three conventional configurations analyzed in this study are the BTMSs using only CPCM, CPCM with aluminum thermal diffusion plates, and CPCM with FHPs. In addition, a CPCM–FHP assisted with liquid cooling at the lateral sides is established to enhance the thermal performance of large-capacity batteries. Moreover, the influences of coolant temperature, the number of FHPs and cooling pipes, and the coolant direction on the temperature field of a BTMS are discussed. Finally, the orthogonal design method is used for the multi-level analysis of multiple factors to improve the light weight of the system. The optimal parameter combination is obtained to achieve the best thermal performance of the BTMS, with the maximum temperature and the temperature difference at 43.17 °C and 3.36 °C, respectively, under a maximum discharge rate of 2C and a high-temperature environment of 37 °C. The optimal scheme is further analyzed and affirmed through the comprehensive balance method.

“…Currently, a BTMS that combines active and passive cooling is a very effective cooling method. The most common ways are to combine composite phase change material (CPCM) with air cooling [4][5][6][7], liquid cooling [8][9][10][11], or heat pipes [12][13][14].…”

“…Passive cooling systems by contrast are lightweight, small, and independent of external power sources, and therefore easily implemented in small battery packs [25]. They are widely used, e.g., in e-bikes or power tool batteries [26]. In passive cooling systems, cells are embedded in materials with high heat conduction to ensure the fast transport of the produced heat to the pack's surface.…”

In the fast-growing but also highly competitive market of battery-powered power tools, cell-pack-cooling systems are of high importance, as they guarantee safety and short charging times. A simulation model of an 18 V power tool battery pack was developed to be able to evaluate four different pack-cooling systems (two heat-conductive polymers, one phase change material, and non-convective air as reference) in an application scenario of practical relevance (the intensive use of a power tool followed by cooling down and charging steps). The simulation comprises battery models of 21700 cells that are commercially available as well as heat transfer models. The study highlights the performance of the different cooling materials and their effect on the maximum pack temperature and total charging cycle time. Key material parameters and their influence on the battery pack temperature and temperature homogeneity are discussed. Using phase change materials and heat-conductive polymers, a significantly lower maximum temperature during discharge (up to 26%) and a high shortening potential of the use/charging cycle (up to 32%) were shown. In addition to the cooling material sweep, a parameter sweep was performed, varying the external temperature and air movement. The high importance of the conditions of use on the cooling system’s performance was illustrated.
