[0036] The following with attached Figure 1 to Figure 2 The lithium-ion battery consistent matching method and system of the present invention will be further described in detail.
[0037] For the consistency matching method of lithium-ion batteries of the present invention, please refer to Figure 1 to Figure 2 , including the following steps:
[0038] A. Install the battery to the test channel: mark at least one battery 3 produced by the same battery production equipment, the same batch, and the same specification and set these batteries 3 on the corresponding test channel, and enter the battery 3 mark into the database ;
[0039] B. Output AC pulse: send two AC pulse signals of different frequencies to each battery 3 on the test channel respectively, and collect the response signal of each battery 3;
[0040] C. Data processing: Data conversion processing is performed on the corresponding response signals of each battery 3 collected to obtain the physical resistance and...
