description The invention relates to a method of the type for estimating state-of-health (SOH) based on a measurement of the internal resistance (Rb) of the battery. According to the invention, the state-of-health is also estimated using a measurement of an internal temperature (Tb) of the battery and the state-of-charge (SOC) thereof. The state-of-health (SOH) of the battery is obtained by means of a pre-established cartography to which the resistance, the measured temperature and the state-of-charge of the battery are applied as input. The invention also relates to a battery measurement sensor and a battery management system adapted to carry out the method of the invention.
