BATTERY CAPACITY PREDICTION METHOD AND APPARATUS, AND ELECTRONIC DEVICE

A battery capacity prediction method and apparatus, and an electronic device. The method comprises: acquiring basic information of a battery under test (S101); on the basis of the basic information, determining a feature extraction model, a feature noise reduction model, and a capacity prediction model for the battery under test (S102); acquiring test data of performing a charge-discharge test on the battery under test (S103); performing effective interception on the test data on the basis of the feature extraction model to obtain a first feature parameter of the battery under test (S104); performing noise reduction processing on the first feature parameter on the basis of the feature noise reduction model to obtain a second feature parameter (S105); and using the second feature parameter as an input of the capacity prediction model, outputting to obtain an estimated capacity value of the battery under test, and storing same in a sample database (S106). Test data is processed by calling different models accor
