Abstract: A method is provided for estimating at least one item of information in relation to a cellular battery of a system comprising N cells able to store electrical energy, where N>1, and each having a current state of charge, a current resistance state of health and a current capacity state of health. This method comprises a step (10-40) of estimating first information representative of a total energy available in the cellular battery as a function of the current resistance states of health, current capacity states of health and current states of charge, and of a time interval for which the cellular battery is allowed to discharge with a chosen discharge current and at a reference temperature.
