[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] This embodiment provides a battery pressure connection charge / discharge detection device, such as... Figures 1 to 7 As shown, the system includes a frame 1, within which a testing station is located. The frame 1 also houses an electrical box 2, a positive electrode probe group 4, and a negative electrode probe group 5, positioned on opposite sides of the testing station. The electrical box 2 is located at the top of the frame 1 and is electrically connected to the positive electrode probe group 4 and the negative electrode probe group 5 via wires. In use, a battery tray containing batteries is first placed on the testing station. Then, the positive electrode probe group 4 is connected to the positive terminal of the battery in the tray, and the negative electrode probe group 5 is connected to the negative terminal. Finally, the electrical box 2 supplies power to the positive electrode probe group 4 and the negative electrode probe group 5, enabling the charging and discharging testing of the batteries in the tray.

[0030] The frame 1 is equipped with a wire guide plate, and the wire guide plate is equipped with a wire tie fixing seat. The wire tie fixing seat can fix the wires connecting the positive probe group 4 and the negative probe group 5 to the electrical box 2 in an orderly manner, ensuring the rationality of the wiring, preventing the wires from being messy and tangled, and also facilitating the daily maintenance and inspection of the line.

[0031] The frame 1 is also provided with a fire extinguishing system located above the detection station, which includes a smoke alarm and a water outlet pipe. When the battery catches fire during the charging and discharging detection process due to high temperature, the smoke alarm can quickly detect the smoke generated by the battery fire and issue an alarm. At the same time, the water outlet pipe can automatically start to extinguish the fire, improving the safety of the entire device.

[0032] Further, two groups of supporting columns 11 are provided at the detection station for supporting the battery tray. The two groups of supporting columns 11 are respectively located on both sides of the detection station. One group of supporting columns 11 is located near the positive probe group 4, and the other group of supporting columns 11 is located near the negative probe group 5. In each group of supporting columns 11, the top of one supporting column 11 is provided with a positioning pin 12. The positioning pin 12 can ensure that the battery tray is accurately aligned when placed, so that the positive probe group 4 and the negative probe group 5 can accurately contact the positive and negative electrodes of the battery in the battery tray, improving the stability and reliability of the detection process. In addition, the positioning pin 12 can also prevent unnecessary movement or deviation of the battery tray during the detection process, further enhancing the safety and accuracy of the operation.

[0033] A reverse prevention pin 13 is also provided at the detection station. The reverse prevention pin 13 is provided on the side surface of the supporting column 11 near the positive probe group 4 or on the side surface of the supporting column 11 near the negative probe group 5.

[0034] Further, two groups of guide columns 14 are provided at the detection station, which are respectively located on the other two sides opposite to the two groups of supporting columns 11. The top of each group of guide columns 14 is provided with an inclined surface. When the battery tray needs to be placed in the detection station, the inclined surface at the top of the guide column 14 can guide the battery tray to enter in the correct direction and angle, improving the accuracy of the battery tray placement.

[0036] The negative probe group 5 comprises a third mounting plate 50, a fourth mounting plate 51 and a plurality of negative probes 52. The third mounting plate 50 is slidingly arranged on the frame 1, and the third mounting plate 50 is provided with a sliding groove. The fourth mounting plate 51 is slidingly arranged on the third mounting plate 50 through the sliding groove.

[0037] Among them, two driving devices 3 are further arranged in the frame 1. One driving device 3 is used to drive the first mounting plate 40 to move back and forth, so that the positive probes 42 in the second mounting plate 41 can contact or separate from the positive electrode of the battery in the battery tray in the detection station. The other driving device 3 is used to drive the third mounting plate 50 to move back and forth, so that the negative probes 52 in the fourth mounting plate 51 can contact or separate from the negative electrode of the battery in the battery tray in the detection station.

The plurality of temperature probes 7 arranged in the second mounting plate 41 correspond to the plurality of positive probes 42 one by one, and the plurality of temperature probes 7 arranged in the fourth mounting plate 51 correspond to the plurality of negative probes 52 one by one. By arranging the temperature probes 7, when the battery in the battery tray is detected in charging and discharging, the temperature probes 7 can accurately monitor the working temperature of each battery cell, prevent accidents caused by not detecting the temperature of the battery in the battery tray in time, and improve the safety of the battery tray in the charging and discharging detection process.

When it is necessary to adjust the pressing amount of the positive probe group 4 and the negative probe group 5 to the battery in the battery tray, the adjusting screw 60 is rotated to make the adjusting screw 60 move axially along the first nut 61, and the adjusting screw 60 is rotated according to the actual requirement to adjust the extension length, so as to change the pressing depth of the positive probe group 4 and the negative probe group 5 when contacting the battery tray. In this way, the contact pressure between the positive probe 42 and the negative probe 52 and the battery can be accurately controlled, and the stability and accuracy of the detection process can be improved.

[0041] The frame 1 is further provided with a scale, the scale is arranged along the moving direction of the adjusting screw 60, and the scale is used to indicate the extension length of the adjusting screw 60. By observing the reading of the scale, the operator can accurately control the moving distance of the adjusting screw 60 located on the first mounting plate 40 and the adjusting screw 60 located on the third mounting plate 50, and make the adjustment of the two consistent, so as to ensure that the pressing amount of the positive probe group 4 and the negative probe group 5 to the battery in the battery tray is uniform, and further improve the stability and accuracy of the detection process.
