Compared with the method of using cables, the line loss is smaller. 2. By setting the clamping unit, the battery unit is clamped to the fixed position of the bracket, and the lifting plate is raised to drive the clamping seat to leave the opening and rise. In this process, the two lifting plates are close to or away from each other. When they are close to each other, the battery unit with a shorter length is installed, and when they are away from each other, the battery unit with a longer length is installed, which improves the applicability of the test. When the inner end face of the clamping pad contacts one end of the battery unit, the driving unit drives the mounting seat and the adjustment seat to slide horizontally. At this time, the inner side of the clamping pad faces the battery unit for positioning, ensuring that the battery unit test is stable and avoiding poor contact or looseness. 3. Before the battery unit is positioned, the lifting plate is raised, the battery unit is placed between the two calibration pieces, and the battery is flush with the inner wall of the lifting plate. When entering the calibration piece, the battery unit is inserted by the clamping block, and the battery units of different lengths are leveled, which increases the test range; 4. A power module is installed on the top of the test rack in each test chamber, which disperses the volume of the previous box-type power supply, reduces the space occupied by the power module in the test chamber, and makes the temperature of the cavity more uniform.

In the detection of charging and discharging of the battery cell, the battery is first placed at the position of the leveling unit, and after being calibrated with the leveling unit, the clamping unit clamps the battery to the position of the clamping unit, that is, the position of each clamping and placement is consistent, which ensures the accuracy of the test and facilitates the power on or off of the conductive copper bus 30, so that the battery cell can be charged and discharged. The opening and closing unit includes a transverse guide rail 6, the upper end of which is provided with a push block 23 for transverse movement, and a cylinder 24 is installed on the support plate at the upper surface end of the transverse guide rail 6. Initially, the push block 23 is located in the middle of the transverse guide rail 6, and the driving end of the cylinder 24 is connected with a telescopic part for longitudinal movement, which fits the push block 23, and the side of the telescopic part is provided with a slot 29 for limiting the conductive copper bar 30, one end of the slot 29 is open, and the end thereof is closed, and the bottom of the power module 5 is closed. The upper part of the test frame 4 is provided with a reinforcing copper bar 28, which is electrically connected to the conductive copper bar 30. The surface of the push block 23 is provided with a notch, and the surface of the telescopic part is provided with a vacant part communicating with the slot 29. When the conductive copper bar 30 is controlled to contact with the power transmission copper bar 28, the cylinder 24 pushes the telescopic part to slide longitudinally, and the battery unit is limited in position by the positioning unit to ensure its stability. At this time, the conductive copper bar 30 is located on one side of the push block 23, that is, the conductive copper bar 30 is located at the position of the conductive copper bar 30. In the middle of the external circuit and the transmission copper bus 28, the telescopic part is reset in the longitudinal direction, and the conductive copper bus 30 enters the slot 29 at this time, and the position of the conductive copper bus 30 is limited. When the battery unit is in the charging state, the push block 23 is driven by the transverse guide rail 6 to move toward the transmission copper bus 28 and contact the transmission copper bus 28. At this time, the power module 5 provides current to the battery unit, and the current flows to the conductive copper bus 30 of the battery unit through the transmission copper bus 28 of the power module 5, and then enters the battery for charging; when discharging, the transverse guide rail 6 drives the conductive copper bus 30 clamped in the telescopic part to move in the opposite direction, and the conductive copper bus 30 is directly connected to the external circuit on the upper part of the push block 23 and located in the test cabin 2.

Compared with the method of using cables, the copper bus connection method has smaller line loss.

[0022] Among them, a power module 5 is installed on the top of the test rack 4 in each test chamber 2, which disperses the volume of the previous box-type power supply, makes the space occupied by the power module 5 in the test chamber 2 smaller, and makes the temperature of the cavity more uniform. The heat dissipation of the water-cooled all-in-one machine adopts a water cooling solution, which is a mature technical means in this field.

The connector 26 slides and fits with the push block 23. When the telescopic part is pushed to move, the slot 29 in the connector 26 has been plugged with the conductive copper bus 30. When charging the battery unit, the telescopic part is pushed to move to the position of the power transmission copper bus 28. In this state, the end of the limit piece 25 slides in the limit cavity at the top of the connector 26 and compresses the elastic piece 27. When charging, the limit piece 25 moves close to the inner end of the limit cavity and stretches the elastic piece 27 until the conductive copper bus 30 is connected to the external circuit.

When the battery unit is clamped to The bracket 3 is fixed in position, and the lifting of the lifting plate 11 drives the clamping seat 15 to leave the opening 14 and rise. In this process, the two lifting plates 11 are close to or away from each other. When they are close to each other, the battery cells with shorter lengths are installed, and when they are away from each other, the battery cells with longer lengths are installed, thereby improving the applicability of the test. When the inner end face of the clamping pad 16 contacts one end of the battery cell, the driving unit 8 drives the mounting seat 9 and the adjusting seat 10 to slide horizontally.

The end of the multi-stage telescopic rod 19 is fixed with a limit block 13 that slides in the guide vertical groove 18 and the guide transverse groove 12. When the lifting and landing plate 11 is subjected to an upward thrust, it rises upward. At this time, the limit block 13 slides in the guide vertical groove 18, and the multi-stage telescopic rod 19 realizes different states according to the movement path of the lifting and landing plate 11, that is, the lifting and landing plate 11 slides toward the middle, and the multi-stage telescopic rod 19 is in an extended and open state at this time; the lifting and landing plate 11 slides near the end, and the multi-stage telescopic rod 19 is in a retracted state.

When entering the correction piece, the battery unit enters through the clamping block 37. Due to the elastic limiting connection between the clamping block 37 and the fixed side plate 36, battery units of different lengths can be leveled, thereby increasing the test range, and the position of the clamping unit for clamping and placing is consistent each time, and there is no need to manually adjust the placement position of the battery unit, thereby ensuring the accuracy of the test.

[0029] When the present invention is used, the battery unit is first calibrated by the leveling unit, and the position of each clamping and placement is consistent to ensure the accuracy of the test. Before the battery unit is fixed, the telescopic part is pushed by the cylinder 24 to slide longitudinally, and then the battery unit is limited in position by the clamping unit.

The copper bus connection method has smaller line loss than the cable method; By setting the clamping unit, the battery unit is clamped to the fixed position of the bracket 3, and the lifting plate 11 is raised to drive the clamping seat 15 to leave the opening 14 and rise. In this process, the two lifting plates 11 are close to each other or away from each other. When they are close to each other, the battery unit with a shorter length is installed, and when they are away from each other, the battery unit with a longer length is installed, so as to improve the applicability of the test.
