| Zusammenfassung: | The invention discloses a storage battery monitoring method and system, and belongs to the technical field of storage battery monitoring, and the method comprises the steps: obtaining the real-time capacity and the rated capacity of a plurality of single storage batteries, and obtaining a first relation model of the residual capacity and the health state of the storage battery according to the real-time capacity and the rated capacity; acquiring actual internal resistance values of a plurality of single storage batteries, and obtaining a second relation model of the internal resistance and the health state of the storage batteries according to the average value of the internal resistance when the service life of the storage batteries ends, the internal resistance when the storage batteries leave the factory and the actual internal resistance of the storage batteries; and fitting the first relation model and the second relation model by using a fast Fourier method to obtain a relation correlation equivalent mo |
