[0033] As Figures 1 to 4As shown, a new energy vehicle battery charging and discharging test device, including test table 1 and aging detector 2 on the test table 1, can be arranged side by side, the aging detector 2 is electrically connected with external line, one end of the external line is electrically connected with external power supply, the new energy vehicle battery charging and discharging test device further comprises:

[0034] Two support seats 3 are arranged on the top of the test table 1.

[0035] The driving part 4 is used for driving the two support seats 3 to move close to or away from each other.

[0036] Several electrical connection parts 5 are arranged side by side on the support seat 3, and the electrical connection part 5 is used for electrically connecting the battery pack with the aging detector 2.

[0037] Two limit parts 6 are arranged on the test table 1, and the limit part 6 is used for arranging the conveying belt and guiding the limit battery pack. The conveying belt can simultaneously pass through the inside of the multiple limit parts 6 arranged side by side, and the conveying belt is transversely parallel to the support seat 3, so that when the conveying belt conveys the battery pack, the electrical connection part 5 can be opposite to the plug-in interface of the battery pack, and the mechanical operation plug-in and pull-out between the two can be facilitated, the power-on, charging and power-off operations can be realized, the mechanical power-on or power-off operation can replace the manual power-on or power-off operation, the multiple battery packs can be uniformly powered on or powered off, the efficiency of the battery pack power-on or power-off operation can be improved, the labor cost can be greatly reduced, the workload of workers can be reduced and the labor intensity of workers can be reduced, and in the process of power-on or power-off of the battery pack, the workers can be prevented from approaching the charging port, and the safety of the power-on or power-off operation can be improved.

[0038] As shown in Figure 2 and Figure 4 The electrical connection part 5 includes a mounting groove 51 arranged in the support seat 3, a limiting through groove 52 is arranged between the inside of the mounting groove 51 and the outside of the support seat 3, and a plug 53 is slidably arranged in the limiting through groove 52.

[0039] The sleeve rod 54 is slidably arranged between the inside of the mounting groove 51 and the outside of the support seat 3.

[0040] The lead wire 56 is electrically connected between the plug 53 and the aging detector 2.

[0041] The telescopic cylinder 55 is arranged in the mounting groove 51, and the telescopic cylinder 55 is used for transversely pushing the plug 53 to move linearly and reciprocally.

[0042] A plurality of support seats 3 can be arranged side by side along the conveying direction of the conveying belt. In this way, a plurality of battery packs can be conveyed side by side to the designated position, so that the plurality of battery packs correspond one by one to the plurality of support seats 3. At the same time, the plug interface on the battery pack can correspond to the plug 53 on the corresponding support seat 3. In this way, the corresponding telescopic cylinder 55 can be controlled to extend to push one end of the plug 53 out of the limiting slot 52 to a certain distance outside. Then, the driving part 4 is operated to drive the two opposite support seats 3 away from each other until the plug 53 is firmly plugged into the plug interface on the battery pack. In this way, simultaneous plugging of a plurality of battery packs can be achieved, the efficiency of connecting the plurality of battery packs to electricity can be improved, the workload of workers during this process can be reduced, and the labor intensity of workers can be reduced, achieving multiple goals at once.

[0043] As shown in Figure 2 and Figure 4 , one end of the wire 56 passes through the inside of the sleeve rod 54, and a plurality of wires 56 are located between the two support seats 3. This design can avoid interference of the wire 56 with the action of the driving part 4 driving the two opposite support seats 3 to move closer to or away from each other. It can also arrange a plurality of wires 56 together to improve the appearance of the wire arrangement.

[0044] As shown in Figure 2 and Figure 4 , the sleeve rod 54 and the plug 53 are located on the opposite two faces of the support seat 3, respectively, and a plurality of sleeve rods 54 are located on the opposite faces of the two support seats 3, respectively. This design allows the battery pack to be conveyed on both sides of the test bench 1 at the same time, increases the number of battery packs tested at one time, thereby improving the efficiency of the entire battery pack test, and relatively reduces the test floor area, thereby improving the space utilization rate in the workshop.

[0045] As shown in Figures 1 to 3 , the limiting part 6 includes a guide seat 61 fixed on one side of the test bench 1. A conveying chute 62 is transversely provided on the top of the guide seat 61. The conveying belt passes through the inside of the conveying chute 62. In this way, the battery pack can be conveyed from the inside of the conveying chute 62, facilitating the operation of the conveying belt to convey the battery pack to the plug 53 corresponding to the plug interface thereon. A side wall 63 is fixed on the side of the conveying chute 62 away from the test bench 1.

[0046] The length of the side wall 63 is equal to the length of the conveying chute 62, and the top of the side wall 63 is higher than the top of the support seat 3. In this way, when the plug 53 is plugged into the plug interface on the battery pack, the side wall 63 can limit and support the battery pack, preventing the battery pack from being pushed when the plug 53 is plugged in. The plug 53 can be plugged in place, avoiding poor electrical connection.

[0047] As shown in Figures 1 to 4The driving part 4 includes two guide grooves arranged opposite to the top of the test table 1, and a rack is slidably arranged in the guide grooves.

[0048] A mounting groove is communicated between the two guide grooves, and a transmission gear is rotatably arranged in the mounting groove.

[0049] A driving motor for driving the transmission gear to rotate.

[0050] The two racks are axially symmetrically arranged on the two sides of the transmission gear, and the mounting groove is located between the two guide grooves.

[0051] In this way, by controlling the forward and reverse rotation of the driving motor, the relative two support seats 3 can be driven to move linearly towards or away from each other, so that the plug 53 and the plug interface on the battery pack can be inserted or pulled out, and the plug-in and pull-out actions of the plug 53 can be replaced by manual operation, and the plug-in and pull-out actions of multiple plugs 53 can be unified, which can improve the efficiency of the plug-in and pull-out actions of the plug 53 and reduce labor costs.

[0052] Working principle: through the conveying belts arranged on both sides of the test table 1, multiple battery packs can be simultaneously conveyed to the designated position and matched with the support seats 3 one by one, at this time, the plug interface on the battery pack will be matched with the corresponding plug 53, then the operator can simultaneously control multiple corresponding telescopic cylinders 55 to extend, push the plug 53 corresponding to the plug interface on the battery pack to a certain distance, and then control multiple driving parts 4 to operate and drive the support seats 3 and the plugs 53 to synchronously approach the battery pack until the corresponding plug 53 is firmly inserted into the plug interface on the battery pack, in this process, the remaining unused plugs 53 on one support seat 3 are in a completely retracted state in the limiting slot 52, so that when the required plug 53 is needed, the corresponding telescopic cylinder 55 can be controlled to push the required plug 53 out of the fixed position, without disassembly and replacement, improving the efficiency of the test operation, after the plug 53 is inserted in place, the aging detector can test the related detection items of the battery pack, after the test is completed, multiple driving parts 4 can be simultaneously controlled to drive multiple support seats 3 to move away from the battery pack, so that the plug 53 and the battery pack are separated, and the pull-out action of multiple plugs 53 is completed, which greatly improves the test efficiency, without manual plug-in and pull-out of the plug 53, greatly reducing the workload of workers and reducing the labor intensity of workers.
