Abstract
The invention relates to a method () for estimating an operating parameter of a battery cell of a battery unit in an electrical propulsion system of a vehicle, the operating parameter being indicative of one of capacity and impedance of the battery cell, the method comprising: selecting () at least one battery cell in the battery unit for determining the operating parameter of the battery cell; providing () a set of state-of-charge (SOC) estimators, each SOC estimator having a selected operating parameter value for a given time period; and using () the set of SOC estimators to determine a value of the operating parameter of the battery cell by performing voltage error minimization.
