A method for determining the operating temperature of a cell of an electric charge accumulator assembly, particularly for electric or hybrid vehicles, is described, said method comprising the steps of:
- providing a reference model of a cell, representative of the evolution over time of a relationship between the internal electrical resistance of the cell and the cell temperature, depending on the state of charge;
- determining the real internal electrical resistance of a cell of an accumulator assembly;
- estimating the state of charge of the cell;
- estimating the ageing of the cell; and
- determining an estimated operating temperature of the cell from the determined value of the real internal electrical resistance of the cell and the estimated state of charge, depending on the degree of ageing of the cell, by comparison with the reference model. |
