Compared to external temperature monitoring and control of batteries, internal temperature monitoring and control can more realistically and directly display the temperature field inside the battery, and can perform thermal management more timely and effectively to prevent battery overheating or thermal runaway.
Battery thermal management (BTM) is a crucial aspect for achieving optimum performance of a Battery Energy Storage System (BESS) (Zhang et al., 2018 ). Battery thermal management involves monitoring and controlling the temperature of the battery storage system to ensure that the battery is always operated within a safe temperature range.
Continuous temperature monitoring and feedback response in the battery storage system is essential for ensuring battery safety and protecting the battery pack from any possible hazard conditions*(Aghajani and Ghadimi, 2018)*.
