摘要： A method for estimating Li-ion battery capacity degradation, comprises: Step I: extracting geometrical features of a reference battery and an estimated battery under different operating conditions; Step II: establishing the intrinsic manifold with the geometrical features extracted in Step I about the reference battery and the estimated battery as inputs respectively, based on the Laplacian Eigenmap (LE) method; and Step III: achieving geometrical metric and estimation of battery capacity with a geodesic on the intrinsic manifold established in Step II about the reference battery and the estimated battery. As can be seen the present capacity estimation method of Li-ion battery is completely based on geometrical features and approaches.
