  "textContent": "The present application relates to the technical field of SOC estimation of a lithium battery, and discloses a method, device and computer readable storage medium for estimating SOC of a lithium battery. State data and corresponding SOC values of lithium batteries under different working conditions are collected to establish a sample set, and clustering analysis is performed on the sample set to obtain a plurality of sample subsets; then a corresponding sub-model is established for each of the sample subsets to obtain sub-model functions of the plurality of sample subsets; next, the state data of a sample to be tested is respectively added into the state data of each of the sample subsets to calculate a change value of the state data of each of the sample subsets before and after the adding operation, and at least one sub-model close to the sample to be tested is selected as the selected sub-model according to the change value; and finally, a weight is assigned to the selected sub-model to calculate the SOC value of the sample to be tested. By obtaining the estimated SOC value of the lithium battery in the aforementioned manner, the accuracy and reliability of the estimated SOC value of the lithium battery can be improved.",
