[0028] Please see Figures 1 to 2The battery OVC testing device is used to test the open circuit voltage, AC internal resistance, and casing voltage of battery 200. Since different battery models, sizes, and testing locations exist, the battery OVC testing device of this application can perform OVC testing on different models of battery 200.

[0029] The battery OVC testing device includes a machine tool 10, a support 20, an alarm 30, a carrier 40, a testing component 50, and a scanning component 60.

[0030] Machine tool 10 is used to fix bracket 20, carrier 40 and test assembly 50.

[0031] The bracket 20 is fixed to the machine tool 10 and perpendicular to the machine tool 10. A display and an alarm 30 are mounted on the bracket 20. The display shows the information of the battery 200 and the test results. When the test results of the battery 200 are unqualified, the alarm 30 will sound an alarm.

[0032] Please continue reading. Figure 3 The carrier 40 includes a main body 41 and a receiving component 42, which are spaced apart. The main body 41 and the receiving component 42 are used to receive the battery 200 and limit the battery 200.

[0035] Please continue reading. Figure 4 as well as Figure 5The test assembly 50 includes a test drive unit 51, a push plate 52, a mounting block 53, and a probe 54. The push plate 52 is drivenly connected to the test drive unit 51, and the test drive unit 51 pushes the push plate 52 to move closer to or away from the battery 200. The probe 54 is mounted on the push plate 52 via the mounting block 53.

[0036] The test drive component 51 can be either a linear module or a cylinder.

[0037] The push plate 52 is fixed to the output end of the test drive unit 51. The push plate 52 has a groove 520, and a sliding groove 521 is provided in the middle of the groove 520. The extending direction of the sliding groove 521 is the same as the extending direction of the groove 520. Multiple locking holes 522 are provided on the bottom wall of the groove 520, and these locking holes 522 are arranged along the extending direction of the groove 520. The mounting block 53 is locked with different locking holes 522, allowing the mounting block 53 to be installed at different positions on the push plate 52, so that the probe 54 corresponds to batteries 200 of different sizes. The multiple locking holes 522 are distributed on two straight lines and located on the upper and lower sides of the sliding groove 521.

[0038] The mounting block 53 is T-shaped, with its protruding portion located in the slide groove 521 and able to move along it. The entire mounting block 53 is located in the groove 520. Locking grooves 530 are provided at both the upper and lower ends of the mounting block 53.

[0041] Please continue reading. Figure 6 as well as Figure 7When using the battery OVC testing device, according to the model and corresponding size of the battery 200, the limiting plate 411 is fixed to the first fixing hole 4101 or the second fixing hole 4102. The mounting block 53 is installed in the corresponding locking hole 522, and the position of the barcode scanner 62 is adjusted. Then, the battery 200 is placed on the carrier 40. At this time, the limiting plate 411 limits the battery 200, and the test drive component 51 drives the push plate 52 to move forward, inserting the probe 54 into the test hole of the battery 200 to perform OVC testing. At the same time, the barcode scanner 62 scans the battery 200 to obtain the information of the battery 200 and records the corresponding OVC test result of the battery 200. When the OVC test fails, the alarm 30 sounds.
