[0019] In one embodiment, the step S1 of constructing corresponding test models respectively according to the plurality of test information includes: S11, formulating test environment information including test temperature information and test humidity information; S12, constructing the battery in three dimensions to obtain a battery model, duplicating the battery model according to the number of test information, and binding the battery model to the test information one-to-one to obtain a test basic model; S13, respectively putting multiple test basic models into different data spaces to obtain multiple test models; As described in the above steps S11-S13, before testing the battery, it is necessary to formulate test environment information for the battery, wherein the test environment information includes test temperature information and test humidity information. The test environment information represents the test environment for the battery. The test is performed at a certain temperature and humidity to understand the performance of the battery. The battery is then three-dimensionally constructed to obtain a battery model. The battery model here serves as a representative model. The battery model is copied according to the number of test information. The battery model can be bound to the test information one-to-one as a test basic model. The test basic model is put into the data space to obtain a test model. In this way, the preparation of data for battery testing is completed, which is convenient for subsequent battery testing.

[0020] In one embodiment, the corresponding standard test models are set corresponding to the plurality of test models, and the association relationship S2 between the standard test model and the corresponding test model is established, including: S21, constructing a standard test model of the battery corresponding to the test information, wherein the standard test model includes a battery model and standard electrical parameter information of multiple test points on the battery model; S22, setting a plurality of marked test points on the test model, wherein the positions of the marked test points on the battery model in the test model are the same as the positions of the test points on the battery model in the standard test model; S23, associating the marked test point with the test point corresponding to the position; As described in the above steps S21-S23, a battery model of the battery and standard electrical parameter information of multiple test points on the battery model are constructed according to the test information as a standard test model.

In this way, when the actual battery is tested subsequently, the data can be compared in a targeted and direct manner, so as to understand whether there are abnormalities in the battery testing process, quickly determine battery failures, and obtain the performance of the battery under different environments.

[0021] In one embodiment, the step S3 of testing the battery according to the test model and collecting test data, synchronizing the test data to the test model, comparing the test data in the test model with the standard test model to obtain difference data, and treating the battery corresponding to the difference data exceeding the safety threshold as a faulty battery includes: S31, setting a plurality of corresponding collection points on the battery corresponding to the positions of the marked test points, testing the battery according to the test model, and obtaining test data during the battery test according to the collection points; S32, collecting the collection points on the battery to obtain a collection surface, configuring corresponding cloud servers corresponding to the marked test points in the test model and collecting them to obtain a receiving surface; S33, setting a transmission frame chain between the acquisition surface and the receiving surface, wherein the transmission frame chain includes a plurality of sub-frame chains and a connection layer between the plurality of sub-frame chains; S34, transmitting the test data to the test model through the transmission frame chain, comparing the standard test model with the test data in the test model to obtain difference data, and treating the battery corresponding to the difference data exceeding the safety threshold as a faulty battery.

[0022] In one embodiment, the step S33 of setting a transmission frame chain between the acquisition surface and the receiving surface includes: S331, setting a circulation channel between the collection point in the collection surface and the corresponding mark test point in the receiving surface, wherein the circulation channel includes two sub-ports of the mark test point, two sub-ports of the collection point, and a connection channel between the sub-port of the mark test point and the sub-port of the collection point, the sub-ports of the two mark test points are set on the mark test point, and the sub-ports of the two collection points are set on the collection point; S332, setting a plurality of transmission carriers in the connection channel between the sub-port of the marking test point and the sub-port of the collection point, and connecting adjacent transmission carriers to obtain a sub-frame chain; S333, connect the transmission carriers between the multiple collection points in the collection surface and the corresponding multiple marking test points in the receiving surface one by one to obtain multiple connection layers, and the multiple transmission carriers in the connection layer have the same movement and are used to store the test data collected by the collection points at the same time.

[0023] In one embodiment, the step S331 of setting a circulation channel between the acquisition point in the acquisition surface and the corresponding marking test point in the receiving surface includes: S3311, two sub-ports are respectively set for the multiple collection points in the collection surface, and the two sub-ports are connected to each other; S3312, respectively set two sub-ports corresponding to the multiple marked test points in the receiving surface, and the two sub-ports are connected to each other; S3313, connect the two sub-ports corresponding to the collection point in the collection surface and the two sub-ports marking the test point in the corresponding receiving surface one by one through the connection channel.

[0024] In one embodiment, the step S333 of connecting the transmission carriers of the connection channels between the multiple acquisition points in the acquisition surface and the corresponding multiple marking test points in the receiving surface in a one-to-one correspondence to obtain multiple connection layers includes: S3331, setting a plurality of prepared spaces inside the transmission carrier, and respectively setting connection ports corresponding to the plurality of prepared spaces of the transmission carrier; S3332. Connect the plurality of reserve spaces to the transmission carriers connected to the remaining transmission carriers through the connection ports to obtain a connection layer, wherein the number of the reserve spaces is the number of the connection channels minus one.

[0025] In one embodiment, the step S34 of transmitting the test data to the test model through the transmission frame chain includes: S341, transmitting the test data collected by multiple collection points to the corresponding connection channel through one of the sub-ports of the same collection point, and loading the test data into the transmission carrier corresponding to the sub-port position; S342, performing mutual backup of test data on corresponding connection ports between transmission carriers in the data layer and storing the test data in corresponding reserve spaces; S343. When the data in the preparation space are inconsistent, the test data with the largest proportion of the same test data in the preparation space is taken as the real data, and the real data replaces the test data in the corresponding transmission carrier until it is transmitted to the sub-port of the marked test point. The test data in the transmission carrier is stored in the marked test point through the sub-port and displayed in the test model.

[0026] As described in the above steps S31-S34, a plurality of corresponding collection points are set on the battery at positions corresponding to the marked test points. The collection points are used to collect test data of the actual battery. There are a plurality of collection points on the battery and they are collected to obtain a collection surface. The corresponding cloud servers are configured for the marked test points in the test model and collected to obtain a receiving surface. The collection surface represents that the plurality of collection points are transmitting test data at the same time. The receiving surface represents that the cloud servers corresponding to the test model are receiving data at the same time. The test data of the plurality of collection points can be transmitted and received at the same time and displayed in the test model, which can greatly improve the collection correspondence of the data for the battery test and better analyze the performance of the battery. During the transmission process, the test data collected by the plurality of collection points are respectively put into the connection channel at the same time according to the collection time. Before the test data is transmitted through the connection channel, the plurality of collection points enter the connection channel through the same sub-port of the collection points. After that, the test data collected at the same time can be put into the transmission carrier in the same connection layer for transmission. During the transmission process, the plurality of transmission carriers in the connection layer are connected through the connection port, and the test data in the corresponding connected collection points are obtained through the connection port and backed up in the corresponding pre- In the preparation space, for example, there are three acquisition points, each acquisition point has a space for storing its own test data, and two preparation spaces, both of which have connection ports, which are connected to the other two transmission carriers respectively, so as to obtain the test data in the other two transmission carriers and store them in the corresponding preparation space. When the data in the transmission carrier is inconsistent with the test data in the other preparation spaces, the same test data with a larger proportion is taken as the real data. For example, the data in the preparation space is consistent, and the test data in the transmission carrier itself is inconsistent with the test data in the preparation space of other transmission carriers. The test data in the preparation space is taken as the real data, and the real data replaces the test data in the corresponding transmission carrier until it is transmitted to the sub-port of the marked test point. The test data in the transmission carrier is stored in the marked test point through the sub-port and displayed in the test model, which can ensure the synchronization and accuracy of the test data transmission, and can make the test data displayed and stored in the test model have the same test data as the real battery test, regardless of its parameters or the time relationship between the test data. It can better understand the performance of the battery test and has a better performance analysis effect. The transmission index is obtained by obtaining the situation during the data transmission of the collection point test, and the formula is: ,in, is the transmission index, The number of transport carriers with real data replacing test data in a single connection layer, To test the number of times real data replaces test data during data transmission in a single connection layer, is the number of transmission carriers in a single connection layer, is a constant greater than zero.
