Abstract

Temperature is a key factor affecting the performance of lithium-ion batteries. Controlling the temperature and surface temperature uniformity of batteries operating in both high- and low-temperature environments is crucial. In this study, a battery thermal management system (BTMS) based on micro heat pipe array (MHPA) was developed. A battery preheating module and heat dissipation module were combined in a simple and efficient way. Three cooling methods were studied with the heat dissipation module, i.e., natural cooling, MHPA cooling, and MHPA-coupled air-cooling. At 35 ℃ and a C-rate of 1.0 C, the maximum temperature of the battery module cooled by MHPA-coupled air-cooling was 44.06 ℃, which was much lower than that by natural cooling (70.20 ℃), and the maximum battery surface temperature difference is 2.76 ℃. For the preheating module, the preheating performance of batteries heated under 15 W and 30 W was compared. At 30 W, the battery temperature increased from −20 ℃ to 20 ℃ in just 5.4 mins, with a maximum temperature difference of 4.78 ℃. Both the system preheating module and heat dissipation module showed excellent performance and had little impact on each other. The experimental results showed that the BTMS- MHPA could not only effectively control the battery temperature and reduced the temperature difference under high-temperature heat dissipation, but also achieved fast and stable temperature rise under low-temperature preheating.

期刊介绍： Thermal Science and Engineering Progress (TSEP) publishes original, high-quality research articles that span activities ranging from fundamental scientific research and discussion of the more controversial thermodynamic theories, to developments in thermal engineering that are in many instances examples of the way scientists and engineers are addressing the challenges facing a growing population – smart cities and global warming – maximising thermodynamic efficiencies and minimising all heat losses. It is intended that these will be of current relevance and interest to industry, academia and other practitioners. It is evident that many specialised journals in thermal and, to some extent, in fluid disciplines tend to focus on topics that can be classified as fundamental in nature, or are ‘applied’ and near-market. Thermal Science and Engineering Progress will bridge the gap between these two areas, allowing authors to make an easy choice, should they or a journal editor feel that their papers are ‘out of scope’ when considering other journals. The range of topics covered by Thermal Science and Engineering Progress addresses the rapid rate of development being made in thermal transfer processes as they affect traditional fields, and important growth in the topical research areas of aerospace, thermal biological and medical systems, electronics and nano-technologies, renewable energy systems, food production (including agriculture), and the need to minimise man-made thermal impacts on climate change. Review articles on appropriate topics for TSEP are encouraged, although until TSEP is fully established, these will be limited in number. Before submitting such articles, please contact one of the Editors, or a member of the Editorial Advisory Board with an outline of your proposal and your expertise in the area of your review.
