when the controller determines that the power battery is located on the lifting pallet 5 according to the information fed back by the first sensor 11, the controller controls the driving motor 1 to rotate in a first direction (taking fig. 1 as an example, the first direction should be clockwise when viewed from the outside of the main frame 4); thereby driving the driving double chain wheel 12 to rotate, the driving double chain wheel 12 further drives the chain 3 to transmit, at the moment, the lower driven chain wheel 8 rotates along with the rotation of the chain 3, thus realizing the clockwise rotation of the transmission component and driving the lifting connecting plate 14 and the lifting supporting plate 5 to move upwards;

when the lifting supporting plate 5 reaches the third height of the turnover supporting plate 6, the power battery pushes the turnover part 6B of the turnover supporting plate 6 to turn upwards, so that the power battery further moves upwards;

when the controller determines that the power battery reaches the second height according to the information fed back by the third sensor 10, the controller controls the driving motor 1 to rotate along the second direction, wherein the second direction is opposite to the first direction, and thus the lifting supporting plate 5 is driven to move downwards;

when the power battery reaches the turnover supporting plate 6 according to the information fed back by the fourth sensor 15, controlling the driving motor 1 to continue rotating along the second direction until the distance between the lifting supporting plate 5 and the turnover supporting plate 6 reaches a preset distance, and controlling the driving motor 1 to stop rotating;

the stacker crane places a fully charged power battery on the lifting supporting plate 5;

when the fully charged power battery is determined to be placed on the lifting supporting plate 5 according to the information fed back by the first sensor 11, the controller controls the driving motor 1 to continue to rotate along the second direction so as to drive the lifting supporting plate 5 to continue to move downwards;

when the lifting supporting plate 5 is determined to be lowered to the first height (the bottom of the main frame 4) according to the information fed back by the second sensor 9, controlling the driving motor 1 to stop rotating;

and then, the power battery assembling and disassembling mechanism is used for installing the full-charge battery on the electric automobile.
