[0017] First, in the present invention, after the voltage sensor on the battery module moving frame is connected to the battery module, the voltage of the battery module can be monitored, and the temperature sensor can be used to conveniently monitor the temperature of the internal environment of the box for detection. The smoke sensor can be used to detect whether there is a fire inside the box. Through the preset threshold judgment, the PLC controller can timely discover abnormal conditions in the box, such as overcharging, over-discharging, too high or too low temperature, etc. The PLC controller intelligently controls the battery box according to the data collection and analysis results.

At this time, the position of the block corresponds to the position at the plate groove, and then under the self-resetting effect of the spring, the block connected to the limit plate is inserted into the position of the plate groove to be fixed. When it is necessary to maintain the transmission components in the transmission groove, it is only necessary to pull the handle so that the pull rod connected to the handle drives the limit plate to slide. When the block at the limit plate is separated from the position at the plate groove, the L-shaped block is flipped so that the L-shaped block hooks the pull handle to limit the position, so that the cover plate can be quickly and conveniently removed from the plate groove to maintain the internal components of the transmission groove.
