Abstract
The disclosure relates to a method performed by a battery monitoring unit configured for estimating a battery discharging current of a battery comprising the steps obtaining a state-of-charge value indicative of a ratio between a current capacity and a maximum capacity of the battery, obtaining sensor data indicative of a first plurality of battery voltage values obtained at multiple subsequent points in time, determining a first voltage trend over time of the first plurality of battery voltage values, estimating a battery discharging current of the battery based on a relation, where the relation is dependent on the first voltage trend over time and the state-of-charge value.
