A battery thermal management system (BTMS) plays a significant role in an electric vehicle (EV)'s battery pack to avoid the adverse effect of extreme heat being generated during application. A heat pipe-based BTMS is regarded as an alternative technique to maintain an optimum working temperature of the lithium-ion batteries (LIBs) used in EVs. In this study, the heat pipe-based BTMS was designed and experimented under high input power. The battery surrogate was sandwiched with L- and I-shaped heat pipes, and heated at 30, 40, 50 and 60 W. The heat pipes' condenser sections were cooled by water at 0.0167, 0.0333 and 0.05 kg/s. Findings revealed that the designed heat pipe-based BTMS could give the maximum temperature ($T_{\max }$) below 55 °C, even at the highest input power, and provide the temperature difference (ΔT) below 5 °C. It exhibited capability to transfer more than 92.18% of the heat generated. Controlling the T_max and ΔT within the desirable range demonstrates that the heat pipe-based BTMS is viable and effective at higher heat loads.

电池热管理系统（BTMS）在电动汽车（EV）的电池组中起着重要作用，以避免在应用过程中产生极高热量的不利影响。基于热管的BTMS被视为一种替代技术，可保持电动汽车中使用的锂离子电池（LIB）的最佳工作温度。在这项研究中，基于热管的BTMS在高输入功率下进行了设计和试验。电池替代品夹在L形和I形热管之间，并分别以30 W，40 W，50 W和60 W加热。热管的冷凝器部分用水以0.0167、0.0333和0.05 kg / s的速度冷却。研究发现，基于热管的BTMS设计可以提供最高温度（${Ť}_{\mathrm{最大限度}}$）低于55°C，即使在最高输入功率下，也要提供低于5°C的温差（ΔT）。它具有传递超过92.18％的热量的能力。将T _max和ΔT控制在理想范围内表明，基于热管的BTMS在较高的热负荷下是可行且有效的。
