    • The invention relates to a method for charging a battery by delivering electrical energy to the battery in a charging step. The method comprises: providing a model of the battery, the model linking at least one external parameter of the battery with at least one internal parameter of the battery, the model mapping the at least one internal parameter on a side reaction and relating the at least one internal parameter to at least one limit being linked with the side reaction; determining at least one reference value for the step of delivering electrical energy to the battery based on the model and the at least one external parameter. The charging step comprises monitoring external parameters and delivering electrical energy to the battery according to the at least one reference value. Further, the invention relates to a method for determining at least one internal parameter of a battery. The method comprises measuring external parameters of the battery and applying the external parameters to a model implementing at least one reaction. The battery is adapted to perform said at least one reaction, and the model provides internal parameters by mapping external parameters onto internal parameters, the mapping being based on the model.
