s2, judging the temperature of the super capacitor module, and controlling the number of fans corresponding to the temperature in the super capacitor module to be started;
and S3, when the temperature is still raised after the preset amount of fans are started, the main control unit is used for controlling the starting quantity of the fans to be continuously increased until the temperature is maintained within a preset range, and if the temperature exceeds the preset range, the main control unit is used for controlling the circuit breaker to be opened.
