A method of estimating a state of charge of an electric battery including a plurality of electric accumulators as cells. The method includes: a) determining a state of charge of each cell of the battery, b) determining a range of use of the battery equal to a maximum predetermined value of the state of charge of a cell minus deviation between the state of charge of a most charged cell and the state of charge of a least charged cell which are determined in a), c) determining the state of charge of the battery as equal to the ratio between the state of charge of the least charged cell determined in a) and the range of use of the battery determined in b).
