When in use, first place the battery inside the battery frame 103. When the battery charging temperature is too high, the heat dissipation fan 105 inside the heat dissipation shell 104 rotates, so as to discharge the heat of the battery in the battery frame 103. In addition, several first heat dissipation slots 106 on both sides of the inner wall of the battery frame 103 can discharge the residual heat in the battery frame 103, and several first through holes 111 on the surface of the cabinet body 101 and several second heat dissipation slots 109 on the surfaces of the first back plate 107 and the second back plate 108 cooperate with the heat dissipation holes 120 to further discharge the heat outside the cabinet body 101, significantly improving the use safety of the battery cabinet for the battery.
