1. An air conditioning system battery box, characterized by the system comprising:
a battery box comprising:
a charging and energy storage unit for charging and storing electrical energy using an input voltage supplied to the battery box;
a power failure detection unit for detecting a power failure of the input voltage; and
a power output switching unit for switching an output based on a detection result of the power failure detection unit, wherein the power output switching unit is configured to output a voltage from the charging and energy storage unit when the power failure detection unit detects a power failure, and is configured not to output the voltage when the power failure detection unit does not detect the power failure; and
a control board circuit for receiving the output voltage from the battery box for a safe operation, wherein the control board circuit is configured to actuate one or more valves to perform a shutdown operation when the output voltage provided by the battery box is greater than a preset threshold.
