[0043] The inverter rectifier cabinet 12 performs inversion and rectification on multiple battery packs 13. Due to its high power, we use the air conditioner 17 to perform constant temperature control on the inverter rectifier room to ensure that the inverter rectifier cabinet 12 is in a normal temperature working environment.

[0044] Furthermore, a plurality of ceiling lights 16 are fixed to the bottom of the top plate 3 , and the plurality of ceiling lights 16 are respectively located above the power storage chamber and the inverter rectifier chamber, wherein a temperature sensor is also provided in the inverter rectifier chamber, and the temperature sensor and the ceiling lights 16 are electrically connected to the industrial computer 11 .
