Abstract
The performance and life span of the power battery are limited by its operating temperature, hence the battery thermal management (BTM) is a key technology for electric vehicle. In this study, a novel BTM system based on composite phase change materials (C-PCM) with aluminum boxes is developed. The temperature control performance of the system is tested at different discharge rates (1C, 2C) at different ambient temperature (0â¯Â°C, 10â¯Â°C, 20â¯Â°C and 30â¯Â°C). The results show that the C-PCM can significantly reduce the average temperature and improve the temperature uniformity of the lithium ion battery pack. Furthermore, the performance of the C-PCM for the thermal control starts to deteriorate after completely melting, therefore an accurate dosage estimation of the C-PCM is a key problem for its application.
