What are the functional goals of battery thermal management system (BTMS)?

The functional goals of the battery thermal management system (BTMS) are to maintain the battery at the optimal operating temperature by heating or cooling, to maintain the temperature consistency among a large number of cells, and to prevent the occurrence and diffusion of thermal runaway , .

Are integrated battery thermal management systems suitable for all climates?

Phase change material (PCM) is widely adopted to construct integrated battery thermal management systems (BTMSs) for all climates. However, integrated BTMSs in cylindrical battery modules remain arduous challenges due to the compact/massive cuboid-shaped PCM module and the curved surface of the cells.

What temperature should a battery module be placed in a thermostat?

During the preheating tests, the battery modules were first placed in the thermostat with simulative ambient temperatures of 0 or -20 °C. After thermal equilibrium, the heating tubes were started up with heating powers of 120, 150, 180, 200 or 220 W at different airflow velocities of 1.8, 2.1, 2.4, 2.7, 3.0 or 3.5 m s −1, respectively.

Can BTMS be integrated in cylindrical battery modules with force air convection?

However, integrated BTMSs in cylindrical battery modules remain arduous challenges due to the compact/massive cuboid-shaped PCM module and the curved surface of the cells. Herein, we propose a novel all-climate BTMS integrating units-assembled composite PCM (CPCM) module with force air convection.
