Accurate State Of Charge estimations are one of the critical functionalities of Battery Management Systems, whether it is for single-cell batteries or multiple-cells batteries. However, battery-SOCs are usually generalized without any consideration about cell disparities. In this presentation, we propose to define a more relevant battery-SOC by analyzing the already existing studies about SOC estimation for single cell (cell-SOC) and by developing a battery-SOC which takes cell disparities into account. A focus is also done to explore how to link uncertainties of cells estimations and accuracy of the final battery-SOC in order to give reliable information to the user about the charge amount stored in the battery. The algorithm is then implemented for numeric analysis and comparisons.
