Abstract (English): To enhance the adaptability of phase change materials (PCMs) to heating power and ambient temperature, a novel strategy is proposed to expand the temperature control range by using binary double-peak PCMs with two heat absorption peaks. The influence of thermal conductivity on the temperature control performance is investigated through thermal simulation of the battery thermal management process. Concurrently, the temperature control performance of the lauric acid-stearic acid binary mixture (LA30-SA70) is evaluated under six ambient temperatures and three heating power levels. It is indicated by the results that the temperature control performance is progressively enhanced with increasing thermal conductivity, but the optimization effect gradually stabilizes. A critical point for the battery pack temperature control optimization is reached when the thermal conductivity is 1.5 W/ (m·K) . Compared with conventional single-peak PCMs lauric and stearic acids, LA30-SA70 demonstrates superior performance across six ambient temperatures, with a maximum temperature difference of less than 1.8 K and excellent ambient temperature adaptability. Under varying heating power conditions, the battery pack temperature is effectively regulated within an optimal range at a low heating power of 10 000 W/m³ . Furthermore, under the combined conditions of an extreme ambient temperature (323.15 K) and an extreme heating power (100 000 W/m³), the battery temperature is successfully constrained within the normal operating range (< 333.15 K), thereby confirming outstanding heating power adaptability.

Abstract (Chinese): 为提高相变储热材料对发热功率和环境温度的适应性, 提出利用具备 2 个吸热峰的二元双峰 相变材料扩大控温范围的新思路, 通过电池热管理过程的热仿真, 探究了导热系数对相变材料控温效 果的影响, 检验了月桂酸–硬脂酸二元混合物 (LA30-SA70) 在 6 种环境温度和 3 种发热功率下的控温 效果. 结果表明: 随着导热系数的提高, 控温效果会逐步增强, 但提升幅度逐渐趋于稳定, 当导热系数 为 1.5 W /( m · K ) 时, 电池组控温效果优化达到临界点. 在 6 种环境温度下, LA30-SA70 相比传统的单 峰相变材料月桂酸和硬脂酸, 具有更出色的控温效果, 最大温差均小于 1.8 K, 具备出色的环境温度适 应性. 在 3 种发热功率下, LA30-SA70 不仅能够在低发热功率 (10 000 W /m³) 下将电池组温度控制在 合理范围内, 还能在极端高温环境 (323.15 K ) 和极端发热功率 (100 000 W /m³) 的共同作用下, 依然 将电池保持在低于 333.15 K 的正常工作温度范围内, 具备出色的发热功率适应性.
