[0054] S13, putting the multiple test basic models into different data spaces to obtain multiple test models;

[0055] 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.

[0056] In one embodiment, the step of setting corresponding standard test models for the plurality of test models and establishing an association relationship S2 between the standard test models and the corresponding test models includes:

[0057] S21. Constructing a standard test model for the battery according 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;

[0058] 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;

[0062] 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 testing process according to the collection points;

[0063] S32, gathering 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 gathering them to obtain a receiving surface;

[0066] In one embodiment, the step S33 of setting up a transmission frame chain between the acquisition surface and the receiving surface includes:

[0067] S331: Setting a circulation channel between a collection point on the collection surface and a corresponding marked test point on the receiving surface, wherein the circulation channel includes two sub-ports of the marked test point, two sub-ports of the collection point, and a connecting channel between the sub-ports of the marked test point and the sub-ports of the collection point, the sub-ports of the two marked test points being set on the marked test point, and the sub-ports of the two collection points being set on the collection point;

[0068] S332: setting a plurality of transmission carriers in the connection channel between the sub-port marking the test point and the sub-port of the collection point, and connecting adjacent transmission carriers to form a sub-frame chain;

[0069] S333. Connect the transmission carriers between the multiple collection points in the collection surface and the corresponding multiple marked test points in the receiving surface in a one-to-one correspondence to obtain multiple connection layers. 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.

[0070] In one embodiment, the step S331 of setting a circulation channel between the acquisition point on the acquisition surface and the corresponding marked test point on the receiving surface includes:

[0071] 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;

[0072] S3312, respectively set two sub-ports corresponding to the multiple marked test points on the receiving surface, and the two sub-ports are connected to each other;

[0073] S3313: Connect the two sub-ports corresponding to the collection point in the collection surface to the two sub-ports corresponding to the marked test point in the receiving surface one-to-one through a connection channel.

[0074] In one embodiment, the step S333 of establishing a one-to-one correspondence between the transmission carriers of the connection channels between the plurality of collection points on the collection surface and the corresponding plurality of marking test points on the receiving surface to obtain the plurality of connection layers includes:

[0075] S3331. Set up multiple reserve spaces inside the transmission carrier, and set up connection ports corresponding to the multiple reserve spaces of the transmission carrier respectively;

[0076] 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.

[0077] In one embodiment, the step S34 of transmitting the test data to the test model via the transmission frame chain includes:

[0078] 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;

[0079] S342, performing mutual backup of test data on corresponding connection ports between transmission carriers in the data layer and storing the data in corresponding reserve spaces;

[0080] S343. When the data in the preparation space is 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.

[0081] As described in steps S31-S34 above, multiple 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 multiple collection points on the battery, which are aggregated to form a collection surface. Corresponding cloud servers are configured for the marked test points in the test model and aggregated to form a receiving surface. The collection surface represents that the multiple collection points are transmitting test data simultaneously, and the receiving surface represents that the cloud server corresponding to the test model is receiving data simultaneously. The test data of multiple collection points can be transmitted and received simultaneously and displayed in the test model, which can greatly improve the correspondence of battery test data collection and better analyze battery performance. During the transmission process, the test data collected by the multiple collection points are simultaneously input into the connection channel according to the collection time. Before the test data is transmitted through the connection channel, the multiple collection points enter the connection channel through the same sub-port of the collection point. After that, the test data collected at the same time can be input into the transmission carrier in the same connection layer for transmission. During the transmission process, the multiple transmission carriers in the connection layer are connected through the connection port, and the test data in the corresponding connected collection points is obtained through the connection port and backed up in the corresponding pre- In the preparation space, for example, there are three collection points, each collection 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, and then the test data in the other two transmission carriers are obtained and stored 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 used 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 the other transmission carriers. The test data in the preparation space is used as the real data, and the real data replaces the test data in the corresponding transmission carrier until it is transmitted to the branch port of the marked test point. The test data in the transmission carrier is stored in the marked test point through the branch 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 test data transmission of the collection point. The formula is: ,in, is the transmission index, The number of transmission carriers with real data replacing test data in a single connection layer, To test the number of times that 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.
