Temperature factors have a vital impact on the performance, life and safety of power batteries. Generally speaking, we expect the battery system to operate in the range of 15-35 C, so as to achieve the best power output and input, the maximum available energy, and the longest cycle life (although cryogenic storage can prolong the calendar life of the battery, but the application of cryogenic storage is not significant, which is very similar to human beings). The refrigeration effect of fluorinated refrigerant is excellent, which can effectively reduce temperature and prevent explosion.
