Knowing the behaviour of batteries is very important for different reasons. In applications such as a vehicle energy management, it is important to know the state of the battery, e.g. what is the remaining driving range or when should the battery be replaced. Also, for the system design, simulation models are important, e.g. to design a suitable cooling system that prevents the battery from dangerous states. Simulation models of secondary batteries: From quantum physics to techno-economic scale gives an overview over the different modelling approaches for battery simulation models used for different purposes, such as battery pack design or state of charge estimation.

Solutions for different applications are presented. A classification into electrical, thermal, ageing models is given as well as according to the degree of precision ranging from physico-chemical, over impedance based to energy flow or empirical models with their specific advantages and disadvantages.
