| description | The invention discloses a lithium battery operation data feature map extraction method and device, a medium and a product, and relates to the field of energy storage of a new energy power system. The method comprises the steps of obtaining operation data of a lithium battery of the energy storage system; selecting target operation data from the operation data by applying a sliding window to obtain a plurality of target data groups; sorting the plurality of operation data in each target data group according to a front-back sequence of preset index moments to obtain an initial matrix; performing mean variance normalization processing on each column of the initial matrix to obtain a normalized matrix; calculating a covariance matrix of the normalized matrix; performing singular value decomposition on the covariance matrix to obtain a feature vector matrix; calculating a dimension reduction matrix corresponding to each target data group according to the feature vector matrix; scaling the dimension reduction matri |
