The correspondence between the type of the battery module 101 and the real-time temperature value is: the temperature value of the normal battery module is smaller than a first preset temperature value, the temperature value of the low-temperature battery module is larger than or equal to the first preset temperature value and smaller than a second preset temperature value, the temperature value of the medium-temperature battery module is larger than or equal to the second preset temperature value and smaller than a third preset temperature value, and the temperature value of the high-temperature battery module is larger than the third preset temperature value. The normal battery module indicates that the battery module 101 is operating at normal temperature at this time, and the low-heat battery module, the medium-heat battery module, and the high-heat battery module indicate that the battery module 101 needs to be subjected to cooling treatment at this time.
In an exemplary embodiment, after the temperature value of each battery module 101 in the energy storage cabinet 100 is obtained, whether a low-temperature battery module exists in each battery module 101 in the energy storage cabinet 100 is determined according to the received temperature value and the corresponding relationship between the type of the battery module 101 and the real-time temperature value, and if the low-temperature battery module exists, a fan corresponding to the low-temperature battery module is controlled to execute the first working mode.
