A Battery Thermal Management System, or BTMS, helps to maintain a battery pack at its optimal temperature range of 20 o to 45 o C regardless of ambient temperature. For each vehicle design, the required performance and cycle life of the battery pack will be considered to determine the specific set point for the battery pack temperature.
In all mobile applications of battery systems, including marine, aviation and road vehicles, thermal management of battery cells is an important factor in vehicle design. The battery thermal management system maintains the battery temperature within the desired operating range. There has been much research on battery thermal management systems.
