Abstract

Abstract: The electric vehicle industry is becoming an increasingly important part of the automotive industry, and the high operating temperature requirements of the batteries at the heart of electric vehicles make the study of battery thermal management systems (BTMS) particularly important. Among these, heat pipe (HP) based battery thermal management systems have a very high heat transfer performance, but are lacking in ensuring uniform temperature distribution. A coupled battery thermal management system that combines the two can combine the advantages and compensate for the disadvantages of both, and is considered to be the most effective system because of its smaller and simpler structure compared to the traditional thermal management methods that mainly use air and liquid as the working medium. One of the most effective systems. This paper will focus on the coupled HP and PCM systems, which have been less studied and applied in the past, and classify and compare the above mentioned thermal management systems according to the types of heat pipes used and the different methods of PCM heat transfer enhancement, and analyse their advantages and disadvantages respectively. Finally, an outlook on future research directions is given, where the use of systems that use multiple thermal management methods in conjunction with each other to ensure continuous battery operation will be the future direction of battery thermal management systems. In addition, this review helps to update the sparse reference literature. Highlights: This review provides a detailed review of BTMS based on heat pipe (HP) coupled phase change materials (PCM). The results of studies on BTMS using different types of HP are summarised and compared The summary and comparison of studies on the thermal management of batteries based on a combination of HP and PCM. Some perspectives on the development direction of battery thermal management systems are presented.
