  • Patent number: 12372582
    Abstract: A SOC estimation method and system with advanced parameter identification and integrating infinite algorithm for battery monitoring is disclosed. According to the dynamic and static characteristics of the battery, a second-order RC equivalent circuit model is established, wherein the state equation and output equation of the model are calculated. A variable forgetting factor recursive least squares algorithm incorporating finite memory is utilized for parameter identification. An adaptive unscented H infinite filter algorithm is combined with a second-order RC equivalent circuit model with known parameters to establish the SOC estimation model, which can accurately reflect the state information of the battery to accurately estimate the SOC value of the battery.
