Abstract

One of the most significant challenges in power batteries of electric vehicles is to enhance the thermal performance and energy efficiency of cylindrical battery systems when subjected to harsh operating conditions. Therefore, a bio-inspired hybrid battery thermal management system (BH-BTMS) is presented combining honeycomb-shaped microchannels with phase-change materials. A multi-objective optimization model is developed to optimize the proposed system’s overall performance using a backpropagation neural network and artificial hummingbird algorithm. Based on the prioritization of optimization objectives, including the system’s temperature rise, temperature uniformity, and liquid pressure drop, the optimal solutions were determined according to the Pareto front. Furthermore, the system’s performance was evaluated under two standard operating conditions. The results reveal that the proposed system is markedly superior to those of conventional liquid cooling systems and the maximum temperature, temperature difference, and fluid pressure drop of the system are reduced by 3.58%, 48.66%, and 68.12%, respectively. The system temperature is maintained within a reasonable range under standard operating conditions. This design may help enhance heat dissipation capabilities and reduce power consumption for BTMS of electric vehicles.

基于人工蜂鸟算法的蜂窝通道电池热管理系统优化设计

如何提高圆柱形电池系统在恶劣工况下的热性能和能效，是电动汽车动力电池面临的最大挑战之一。为此，提出了一种结合蜂窝状微通道和相变材料的仿生混合电池热管理系统（BH-BTMS）。利用反向传播神经网络和人工蜂鸟算法建立了多目标优化模型来优化系统的整体性能。根据系统温升、温度均匀性、液压降等优化目标的优先级，根据Pareto前沿确定最优解。并在两种标准工况下对系统性能进行了评价。结果表明，该系统的最高温度、温差和流体压降分别降低了3.58%、48.66%和68.12%，明显优于传统的液冷系统。在标准运行条件下，系统温度保持在合理范围内。该设计有助于提高电动汽车BTMS的散热能力，降低功耗。
