Abstract

Battery thermal management system (BTMS) are essential for maintaining battery performance and safety in electric vehicles (EVs). This paper presents a novel hybrid BTMS (HBTMS) designed to improve performance subject to both cooling and heating requirements. The proposed system integrates micro-channel liquid cooling and phase change materials (PCM) used in a novel sandwich hybrid cooling plate (SHCP) design. This study thoroughly evaluates the performance of this design under various operating conditions. The results demonstrate that the proposed design reduces the maximum temperature by 3.86 K and 4.68 K compared with that of the conventional design. In addition, the temperature uniformity of the battery was improved at both the single-cell and module levels. Furthermore, the proposed design avoids introducing additional heating burden and delays the cooling process during low-temperature rest conditions, with the battery temperature increasing by 6.1 K and 11.4 K after 1 h of rest. Specifically, under cycling conditions, the proposed design increased the PCM melting fraction by 0.03–0.04 and enabled rapid latent heat release, while reducing the high-load operation time of the liquid cooling system by 61 % and 67 %, and decreasing the pumping energy consumption by 51–53 %. Finally, the proposed design delays battery thermal abuse under BTMS failure conditions. Overall, the proposed design simultaneously optimizes the cooling and heating functions, providing enhanced thermal performance, improved energy efficiency, and increased safety for EVs battery applications.

一种结合相变材料和微通道液体冷却的新型混合电池热管理方法

电池热管理系统（BTMS）是保证电动汽车电池性能和安全性的关键。本文提出了一种新型混合BTMS (HBTMS)，旨在提高冷却和加热要求的性能。该系统集成了微通道液体冷却和相变材料（PCM），用于新型夹层混合冷却板（SHCP）设计。本研究全面评估了该设计在各种工况下的性能。结果表明，与传统设计相比，该设计的最高温度分别降低了3.86 K和4.68 K。此外，电池的温度均匀性在单电池和组件水平上都得到了改善。此外，该设计避免了在低温休息条件下引入额外的加热负担并延迟了冷却过程，在休息1 h后电池温度分别提高了6.1 K和11.4 K。具体而言，在循环工况下，所提出的设计将PCM熔化分数提高了0.03 ~ 0.04，实现了快速潜热释放，同时将液冷系统的高负荷运行时间缩短了61%和67%，将泵送能耗降低了51 ~ 53%。最后，提出的设计延缓了电池在BTMS失效条件下的热滥用。总体而言，该设计同时优化了冷却和加热功能，为电动汽车电池应用提供了更强的热性能、更高的能源效率和更高的安全性。
