Thermal Performance on a Vapor Chamber-Based Battery Thermal Management System

The performance of LIB is subject to its operating temperature. High temperature and low temperature may both lead to a capacity loss and affect the life expectancy of a battery. Temperature difference within a battery pack also has a negative effect on the charging and discharging efficiency of a battery. Therefore, battery thermal management system (BTMS) is essential to ensure the battery pack operate within a temperature range of 25–40 °C, and to limit the temperature difference within 5 °C.
