[0031] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0032] Embodiment: When the test equipment tests the battery cluster, two sets of connecting wires are generally used to connect the positive and negative electrodes of multiple battery packs respectively. However, the two sets of connecting wires are easily entangled during actual wiring, and the positive and negative connecting wires are connected incorrectly, resulting in damage to the electrical box 2. At the same time, it may also cause personal injury.

[0033] In order to solve the above problems, Figure 1 As shown, some embodiments provide a battery cluster test device, including: a plurality of test stations, on which battery cells 1 are placed. At the same time, an electrical box 2 is provided on the test station, and one electrical box 2 corresponds to one battery cell 1. The battery cells 1 are electrically connected to the electrical boxes 2 one by one. Through the above arrangement, a plurality of electrical boxes 2 are provided, and when connecting, one electrical box 2 is connected to one battery cell 1 separately, thereby avoiding the phenomenon of cable entanglement and wrong connection when multiple battery cells 1 need to be connected.

[0034] In some embodiments, the electrical box 2 is provided with an independent connection line 21, and the independent connection line 21 of one electrical box 2 is electrically connected to the positive and negative electrodes of the corresponding battery unit 1. The electrical box 2 is electrically connected to the positive and negative electrodes of the corresponding battery unit 1 through the independent connection line 21, thereby achieving a regular connection effect between the electrical box 2 and the battery unit 1, and avoiding the phenomenon of wrong connection caused by entanglement when connecting multiple battery units 1.

[0035] like Figure 3As shown, in some embodiments, in order to facilitate the planning of the placement of each electrical box 2 and each battery cell 1, so as to effectively improve the wiring efficiency, the battery cluster test equipment includes a test rack 3, and the test stations are arranged in sequence along the test rack 3. Each electrical box 2 is arranged above the test rack 3, and each battery cell 1 is arranged below the test rack 3. After each battery cell 1 and electrical box 2 are placed, the electrical box 2 is connected to the positive and negative electrodes of the corresponding battery cell 1 from top to bottom through an independent connecting line 21.

[0036] In some embodiments, in order to facilitate the testing of the battery cells 1, the battery cluster testing device also includes a charging and discharging device 4, and the charging and discharging device 4 is electrically connected to each of the electrical boxes 2. After the charging and discharging device 4 is electrically connected to each electrical box 2, it is electrically connected to each of the battery cells 1 through the electrical box 2 to achieve the effect of testing the battery cells 1. After the battery cell 1 detection is completed, it is only necessary to disconnect the battery cell 1 from the electrical box, and there is no need to disconnect the electrical box 2 from the charging and discharging device 4. That is, it is only necessary to ensure that the connection between the electrical box 2 and the charging and discharging device 4 is correct, and there is no need to change the cable between the electrical box 2 and the charging and discharging device 4. It is only necessary to connect or disconnect each electrical box 2 from the corresponding battery cell 1.

[0037] In some embodiments, the charging and discharging device 4 is provided with a positive electrode connection busbar 41 and a negative electrode connection busbar 42, and the electrical box 2 is provided with a branch connection line 22. The charging and discharging device 4 is electrically connected to each branch connection line 22 through the positive electrode connection busbar 41 and the negative electrode connection busbar 42 to achieve electrical connection with each electrical box 2.

[0038] In order to improve the overall test efficiency of the battery cluster test equipment, in some embodiments, the test station is divided into several test groups, and each of the test groups is turned on in sequence. That is, when the battery cell 1 in one test group is tested, the other test groups are disconnected from the charging and discharging equipment 4. At this time, the other test groups can be disassembled and replaced. After the test of one test group is completed, it can be switched to other installed test groups. By switching the test groups, the test efficiency of the battery cluster test equipment can be significantly improved. Preferably, the test station is divided into a first test group 5 and a second test group 6, and the first test group 5 and the second test group 6 are turned on alternately. When the first test group 5 is testing, the second test group 6 installs the battery cell 1. After the first test group 5 is tested, the second test group 6 is connected to the charging and discharging equipment 4, and the first test group 5 is disconnected. At this time, the first test group 5 installs the battery cell 1.

A second switching switch 44 is provided between the charge-discharge device 4 and the second test group 6. When the first switching switch 43 is turned on, the first test group 5 is disconnected from the charge-discharge device 4. When the first switching switch 43 is closed, the first test group 5 is connected to the charge-discharge device 4. When the second switching switch 44 is turned on, the second test group 6 is disconnected from the charge-discharge device 4. When the second switching switch 44 is closed, the second test group 6 is connected to the charge-discharge device 4. The first switching switch 43 and the second switching switch 44 alternately switch between the open and closed states.

[0040] The first switching switch 43 is electrically connected to the positive connection bus 41 and the branch connection line 22 of the electrical box 2 in the first test group 5. The second switching switch 44 is electrically connected to the positive connection bus 41 and the branch connection line 22 of the electrical box 2 in the second test group 6.

[0041] like Figure 2 As shown, in some embodiments, preferably, the end of the positive electrode connecting busbar 41 has two positive electrode branches 411, and the end of the negative electrode connecting busbar 42 has two negative electrode branches 421. The two positive electrode branches 411 are electrically connected to the first switch 43 and the second switch 44 respectively, and the two negative electrode branches 421 are electrically connected to the first switch 43 and the second switch 44 respectively.
