摘要: One or more embodiments of the present specification provide a method and device for capacity degradation prediction of a lithium-ion battery. The method comprises the following steps: acquiring an original battery discharge capacity; decomposing the original battery discharge capacity through a predetermined mode decomposition method to obtain battery discharge capacities composed of a plurality of different frequency signals; inputting the respective frequency signals into a pre-constructed capacity prediction model to obtain capacity prediction results corresponding to the respective frequency signals; selecting capacity prediction result that satisfies a predetermined relevance condition corresponding to the respective frequency signals; and reconstructing the finally predicted battery discharge capacity according to the capacity prediction result that satisfies the predetermined relevance condition.
