[0039] The working principle of a battery charging and discharging device disclosed by the present invention is as follows.

[0040] (1) In the initial state, according to the different starting times of charging and discharging of different batteries 411, the fixing bolt 410 is removed. Then, according to the scale on the scale 207, the positions of different following folding rods 407 on the outer surface of the moving rod 404 are adjusted. The later the starting time of the charging or discharging process, the farther the distance between the following folding rod 407 and the separating rod 409. When the distance is adjusted, the following folding rod 407 is fixed on the outer surface of the moving rod 404 through the fixing bolt 410 and the threaded hole 403.

[0041] (2) The first motor 401 and the second motor 502 are started simultaneously. The first motor 401 drives the first connecting rod 402 to rotate. The first connecting rod 402 drives the second connecting rod 408 to move. The second connecting rod 408 drives the end shaft 406 to move. The end shaft 406 drives the folding rod 405 to slide along the mounting bracket 1. Then, the folding rod 405 drives the moving rod 404 to slide along the mounting bracket 1. Then, the movement of the moving rod 404 drives the separating rod 409 to move. When the separating rod 409 moves to contact the following folding rod 407, the following folding rod 407 drives the terminal 307 to move, so as to disconnect the connector 308 from the battery 411, and then complete the disconnection working process.

[0042] (3) When the second motor 502 starts, it drives the cooling fan 503 to rotate, and blows the flowing air to the battery 411 through the cooling holes 203, so as to complete the heat dissipation. When the following folding rod 407 moves, the following folding rod 407 drives the contact rod 506 to move. When the contact rod 506 contacts the corresponding contact switch 505, the second motor 502 connected to the corresponding contact switch 505 is turned off, so as to stop the heat dissipation when the disconnection working process is realized.

[0043] (4) The electric energy discharged from the battery 411 is sent into the first wire 305 through the intermediate power supply 304 by the discharge circuit 205 and stored. Then, it charges the battery 411 connected to the second power connection slot 302 through the first wire 305, and supplies power to the first motor 401 and the second motor 502 through the first wire 305.
