Energy storage battery energy management system and method

The invention discloses an energy management system and method for an energy storage battery, and the method comprises the steps: obtaining the working information of the energy storage battery, carrying out the working state judgment of the working information of the energy storage battery, and carrying out the analysis of a fault cause if the working state is a fault state, so as to obtain a normal fault and an abnormal fault; if the fault analysis result is a normal fault, obtaining the load capacity of the fault battery to obtain load data; performing load analysis on the normal batteries based on the load data to obtain a first distribution sequence, and performing load distribution on the load data based on the first distribution sequence; if the fault is an abnormal fault, a maintainer is notified to carry out fault maintenance on the load; if maintenance cannot be carried out, load screening is carried out on the normal batteries to obtain a screening result; and performing cost performance analysis o
