[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-4 As shown, this embodiment provides a battery capacity performance testing fixture, including a battery delivery machine 1 and a battery rack 2. A placement fixture 3 is arrayed on the upper surface of the battery rack 2, and a battery 4 is disposed inside the placement fixture 3. A relay board 5 is installed on one side of the upper end of the battery delivery machine 1, and an upper power connection cover 9 is disposed below the relay board 5. A positioning plug 301 is installed on the upper surface of the placement fixture 3, and a magnetic clamping post 302 is installed on the upper surface of the positioning plug 301. A positioning insertion hole 901 is opened below the upper power connection cover 9 corresponding to the position of the positioning plug 301. A limit insertion hole is provided on the inner side of hole 901 corresponding to the position of magnetic suction post 302. An embedded groove 303 is provided inside the placement fixture 3. A clamping cover plate 304 is installed inside the embedded groove 303. The inner diameter of the embedded groove 303 is longer than the outer diameter of the clamping cover plate 304. An elastic rotating shaft 305 is connected between the clamping cover plate 304 and the placement fixture 3. The clamping cover plate 304 is rotatably connected to the placement fixture 3 through the elastic rotating shaft 305. An electrical contact piece 902 is installed on the lower surface of the upper electrical cover 9. The electrical contact piece 902 is electrically connected to the inspection wiring 6.

[0022] like Figure 2-3 As shown, in this embodiment, a test cable 6 is connected between the relay board 5 and the upper power cover 9. A movable slide rail 8 is provided above the relay board 5 inside the battery rack 2. The relay board 5 is slidably connected to the movable slide rail 8. A data acquisition cable 7 is connected between the battery delivery machine 1 and the relay board 5. The battery delivery machine 1 is electrically connected to the relay board 5 through the data acquisition cable 7.

[0023] The working principle of this utility model is as follows: When in use, the battery 4 is placed vertically upwards inside the placement fixture 3. When the battery is inserted into the placement fixture 3, the battery 4 presses against the inner groove 303 inside the placement fixture 3 and rotates through the elastic rotating shaft 305, causing the clamping cover 304 to be pressed into the inner groove 303. This ensures the stability of the battery 4 inside the placement fixture 3. When testing is required, the upper power cover 9 is pulled downwards, and the inspection wiring 6 is stretched. The positioning insertion hole 901 at the lower end of the upper power cover 9 is aligned with the positioning block 301 at the upper end of the placement fixture 3. The magnetic suction pin 302 inside the positioning block 301 is inserted into the hole in the positioning insertion hole 901 for adsorption and fixation. Therefore, the positioning insertion hole 901 on the lower surface of the upper power cover 9 can quickly contact the power end of the battery 4 to supply power, so that the battery capacity performance can be tested by the battery delivery machine 1.
