Claim 12:
13. A battery system comprising a battery comprising a plurality of battery cells and a battery control unit, where the battery control unit is configured to:
measure a first battery property and a battery temperature of a battery in a vehicle;
calculate a state-of-health, SoHcalc, of a battery cell for the determined battery property using a predetermined model;
provide a function ƒ estimating a battery cell degradation rate;
update a state-of health estimated in a previous time step according to

SoHest←SoHest+ƒ·dt+K·(SoHcalc−SoHest),, where K is a gain factor which is a dependent on operating conditions of the vehicle, and wherein K is modified for each time step using a reinforcement learning agent.
