1. A battery management system comprising:

  • an input which receives input signals representative of a physical quantity of a battery; and

    aprocessor which calculates at least one physical quantity of the battery at least partially based on the input signals and a battery temperature, and generates an output signal derived from the calculated physical quantity;

    calculates the physical quantity based on an electrochemical/physical model of the battery;

    the model including at least one representation of a main electrochemical storage reaction;

    calculates the battery temperature based on a temperature model of a temperature development in the battery and calculates the behaviour of the representation in dependence on the calculated battery temperature; and

    derives the output signal at least partially from a state of the representation.
