The battery testing system includes a controller 102 and a plurality of test fixtures 104, the driving modes of each test fixture 104 are consistent, and the controller 102 is connected in communication with each test fixture 104. The controller 102 obtains the position information sent by the target test fixture, and the target test fixture is one of the multiple test fixtures 104; when the position information meets the preset position conditions, the target test fixture is controlled to switch to the test position; the target test fixture is controlled to test the battery to be tested to obtain test data. Among them, the controller 102 can be a terminal or a server. The terminal can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices, and the server can be implemented with an independent server or a server cluster composed of multiple servers.

[0042] In an exemplary embodiment, as shown in FIG2 , a battery testing method is provided, the method is applied to the controller 102 of the battery testing system shown in FIG1 , the battery testing system further includes a plurality of test fixtures 104 , and the controller 102 in the method is used as a terminal for illustration, the method includes the following steps 202 to 206 . Among them:

[0043] Step 202: Acquire the location information sent by the target test fixture.

[0044] The target test fixture is one of a plurality of test fixtures, and the driving modes of the test fixtures are consistent.

[0045] FIG3 shows a schematic diagram of the structure of a test fixture in an embodiment of the present application. In a possible embodiment, as shown in FIG3 , the test fixture includes: a carrier 1 for accommodating a battery to be tested; a holding module 2 for connecting to a test probe and for crimping with the tab of the battery to be tested; a first drive member (not shown in the figure), respectively connected to the carrier and the controller, for controlling the carrier to switch between a loading position and a test position according to a control instruction of the controller; a second drive member 3, respectively connected to the holding module and the controller, for controlling the holding module 2 to crimp with the tab according to a control instruction of the controller; a slide rail 4, arranged at the bottom of the carrier 1; a first position limit block 5, arranged at the first end of the slide rail 4; a second position limit block 6, arranged at the second end of the slide rail 4.

[0046] The driving modes of each test fixture are consistent, specifically including: the structure of each test fixture is consistent, and the process of crimping and testing the battery to be tested is consistent. Among them, structural consistency includes the consistency of the structure and connection relationship of each module in each test fixture, and also includes the consistency of the type and model of each device. Exemplarily, the consistency of the devices in each test fixture includes: the quality and material of the pressure plate in the holding module 2 are consistent, and the cylinder diameter and shape of the cylinder in the driving module are consistent.

[0047] In this step, since the driving modes of the test fixtures are consistent, the controller can control the test fixtures to test the battery to be tested based on a unified control process and control instructions, so as to save hardware resources and software resources and improve test efficiency.

[0048] Step 204 : When the position information meets the preset position condition, the target test fixture is controlled to switch to a test state.

[0049] In a possible implementation, the position information includes first position information and second position information. Continuing to refer to Figure 3, the test fixture provided in the embodiment of the present application also includes a first position sensor and a second position sensor, and the first position sensor and the second position sensor are respectively communicatively connected to the controller. Optionally, the first position sensor can be arranged on the first position limit block 5, for collecting position information of the battery to be tested, obtaining the first position information and transmitting it to the controller. Optionally, the second position sensor can be arranged on the top of the carrier 1, for collecting position information of the battery to be tested, obtaining the second position information and transmitting it to the controller.

[0050] Optionally, the first position sensor and the second position sensor can collect position information according to a preset collection frequency, and transmit the collected position information to the controller according to a transmission frequency, and the transmission frequency can be consistent with the collection frequency or lower than the collection frequency. Optionally, the first position sensor and the second position sensor can collect position information according to an operation instruction of an operator and transmit the collected position information to the controller.

[0051] Step 204 further includes: when the first position information meets the preset first position condition, controlling the carrier 1 of the target test fixture to switch from the loading position to the test position; when the second position information meets the preset second position condition, controlling the holding module 2 of the target test fixture to be crimped with the tab of the battery to be tested, and the target test fixture enters the test state.

[0052] Among them, before testing the battery to be tested, the target test fixture is in an initial state, and the carrier 1 of the target test fixture is in the loading position. At this time, the carrier 1 is close to the first position limit block 5, and the operator can easily place the battery to be tested on the carrier 1; the holding module 2 is separated from the carrier 1.

[0053] Optionally, the first position condition may include that the battery cell of the battery to be tested matches the battery cell accommodation area of ​​the carrier 1; the tab of the battery to be tested matches the tab accommodation area of ​​the carrier 1. The controller receives the first position information and determines whether the first position information meets the first position condition. When the first position information meets the preset first position condition, the carrier 1 of the target test fixture is controlled to switch from the loading position to the test position, and the carrier 1 is close to the second position limit block 6 and the holding module 2. In one possible embodiment, the first position information does not meet the first position condition, and the controller generates an alarm message for the operator to adjust the placement position of the battery to be tested according to the alarm message.

[0054] Optionally, the second position condition may include that the tab of the battery to be tested matches the downward position of the pressing module 2. The controller receives the second position information and determines whether the second position information meets the second position condition. When the second position information meets the second position condition, the pressing module 2 is controlled to be crimped with the tab of the battery to be tested, and the target test fixture enters the test state. In one possible embodiment, the second position information does not meet the second position condition, and the controller controls the first driving member of the target test fixture to drive the carrier 1 to adjust the position, or controls the second driving member 3 to drive the pressing module 2 to adjust the position until the second position information meets the second position condition.

[0055] Step 206, controlling the target test fixture to test the battery to be tested to obtain test data.

[0056] The above-mentioned battery testing method is applied to the controller of the battery testing system, and the battery testing system also includes multiple test fixtures, and the driving modes of each test fixture are consistent. The method includes: obtaining the position information sent by the target test fixture, and the target test fixture is one of the multiple test fixtures; when the position information meets the preset position conditions, controlling the target test fixture to switch to the test state; controlling the target test fixture to test the battery to be tested and obtain test data. In this embodiment, when it is necessary to switch different models of batteries to be tested, the controller determines the target test fixture from multiple test fixtures based on the model of the battery to be tested, and then controls the target test fixture to test the battery to be tested, avoiding the problem of low test efficiency and high resource utilization rate caused by one controller controlling one test fixture in the prior art, which can effectively reduce the operation complexity and resource utilization during the test process, thereby improving the test efficiency of the battery testing method.

[0057] Based on the embodiment shown in Figure 2, in the battery testing method provided in one embodiment of the present application, before obtaining the location information sent by the target test fixture, the method also includes: obtaining first identification information sent by the first identifier, the first identification information being obtained by the first identifier performing identification processing on the battery to be tested; and determining the target test fixture from multiple test fixtures based on the first identification information.

[0058] Before loading the battery to be tested into the target test fixture, the operator uses the first identifier to identify the battery to be tested, obtains first identification information corresponding to the battery to be tested and transmits it to the controller; the controller determines the target test fixture corresponding to the battery to be tested from multiple test fixtures based on the first identification information and the pre-stored battery fixture mapping relationship, so that the controller can display the identification information of the determined target test fixture for the operator's reference to load the battery to be tested into the target test fixture; on the other hand, the controller is connected to the target test fixture for communication, the controller obtains the location information sent by the target test fixture, and controls the target test fixture.

[0059] In a possible implementation, the target test fixture can be manually selected by an operator, who obtains the first identification information corresponding to the battery to be tested, determines the target test fixture corresponding to the battery to be tested from multiple test fixtures, and establishes a communication channel between the controller and the target test fixture, so that the controller can obtain the position information sent by the target test fixture and control the target test fixture. Exemplarily, the controller is connected to each test fixture via a communication cable, and the operator can turn on the communication cable between the controller and the target test fixture by closing the switch on the communication cable corresponding to the target test fixture.

[0060] Based on the embodiment shown in FIG. 2 , the battery testing method provided in an implementation of the present application further includes: acquiring second identification information sent by a second identifier; and obtaining test information corresponding to the battery to be tested according to the second identification information and the test data.

[0061] Optionally, the second identifier may be disposed on the target test fixture. Before the target test fixture starts to test the battery to be tested, the second identifier performs identification processing on the battery to be tested placed on the target test fixture, obtains second identification information and transmits it to the controller.

[0062] Optionally, the second identifier is based on an inductive identification method, and when it senses that the battery to be tested enters the identification area, the battery to be tested is identified. Optionally, in combination with the foregoing embodiment, after determining that the first position information or the second position information meets the preset position condition, the controller sends an identification instruction to the second identifier, controls the second identifier to approach the battery to be tested, and identifies the battery to be tested. Optionally, the second identifier can obtain second identification information by performing identification processing under the control instruction of the controller or according to a preset identification frequency. The controller combines the second identification information with the test data according to a preset message format to obtain the test information of the battery to be tested. In this way, the test information summarizes the correspondence between the identification of the battery to be tested and the test data, and the operator can quickly determine the battery to be tested with a specific identification and its corresponding test data based on the test information, thereby improving the test efficiency of the battery testing method.

[0063] In a possible implementation, the first identifier and the second identifier are both barcode scanners, which respectively scan and identify the identification corresponding to the battery to be tested to obtain the first identification information and the second identification information corresponding to the battery to be tested. The controller can improve the accuracy and reliability of the battery testing method and avoid misoperation by verifying the first identification information and the second identification information.

[0064] In an exemplary embodiment, as shown in FIG4 , a battery testing method is provided, the method is applied to the controller 102 of the battery testing system shown in FIG1 , the battery testing system further includes a plurality of test fixtures 104 , and the controller 102 in the method is used as a terminal for illustration, the method includes the following steps 401 to 409 . Among them:

[0065] Step 401: Acquire first identification information sent by a first identifier.

[0066] The first identification information is obtained by performing identification processing on the battery to be tested by the first identifier.

[0067] Step 402: determine a target test fixture from a plurality of test fixtures according to the first identification information.

[0072] Step 406, when the second position information meets the preset second position condition, the pressing module 2 of the target test fixture is controlled to press the tab of the battery to be tested, and the target test fixture enters the test state.

[0073] Step 407 , when the second position information does not meet the second position condition, control the holding module 2 or the stage 1 to adjust the position.

[0074] Step 408, controlling the target test fixture to test the battery to be tested to obtain test data.

[0075] Step 409: Obtain test information corresponding to the battery to be tested according to the second identification information and the test data.
