Lithium battery pack temperature regulation

According to Ji et al. [9], the maximum temperature range before performance degradation for a lithium-ion battery is 253.15 K to 333.15 K, while the optimal operating range is between 298 K and 313 K. Uneven temperature distribution can also affect the battery lifespan, so the difference in maximum and minimum temperatures in a battery pack should be less than 5 K to achieve the best performance [10].
