Energy storage system SOC automatic management method and system

The invention provides an energy storage system SOC automatic management method and system, and belongs to the technical field of energy storage devices, and the method specifically comprises the steps: determining the adjustment probability of different charge and discharge depth intervals of an energy storage system through the historical adjustment data of different charge and discharge depth intervals of the energy storage system; the SOC operation interval of the energy storage system is determined by combining the historical charge-discharge depth of the energy storage system, and the aging coefficient of the energy storage battery and the unreliable battery are determined through the charge-discharge depth, the historical adjustment frequency and the charge-discharge curve of different energy storage batteries of the energy storage system; the SOC adjustment coefficient is determined according to the number, capacity and real-time operation data of the unreliable batteries and the problematic energy st
