Abstract (en)
[origin: WO2010103216A1] The invention relates to a method for estimating the equilibrium electromotive force (Femeq) of a battery, based on data relating to the evolution over time of the no-load voltage at the terminals of such a battery during relaxation. The data can be obtained from preliminary tests on such a battery under different temperature conditions. The invention also relates to a method for estimating the state of charge (SOC) of a battery based on the equilibrium electromotive force. The state of charge estimation is based on data relating to the correspondence between a defined state of charge and a defined equilibrium electromotive force at a given temperature. The data can be obtained by preliminary tests on such a battery under different temperature conditions.
