Single body SOC estimation method and device, equipment and storage medium

The invention relates to a single body SOC estimation method and device, equipment and a storage medium, and relates to the technical field of intelligent control. The method comprises the following steps: firstly, generating an equivalent circuit model of the series battery pack, and determining a reference monomer based on a plurality of monomers in the series battery pack; and then, according to the equivalent circuit model, obtaining a reference SOC of the reference monomer and a monomer OCV deviation of the to-be-tested monomer, and further determining a monomer SOC estimated in real time for the SOC of the to-be-tested monomer. Therefore, the SOC of each single battery can be accurately estimated in the battery pack. 本申请涉及一种单体SOC估计方法、装置、设备及存储介质，涉及智能控制技术领域。该方法包括：首先生成串联电池组的等效电路模型，并基于串联电池组中多个单体确定参考单体。然后根据等效电路模型，得到参考单体的参考SOC，以及待测单体的单体OCV偏差，进一步确定针对待测单体的SOC实时估计的单体SOC。由此，可以实现在电池组中，准确估算各个单体电池的SOC。
