// Modelling and simulation

Modelling and simulation are used in the battery system technology field to qualitatively and quantitatively recreate the properties and behaviour of batteries, describe them mathematically and finally connect them with other system components in a simulation environment.

Non-linear static correlations are depicted in look-up tables or as parametrisable algebraic equations. The behaviour models are depicted using differential algebraic model structures. Based on tests, the model parameters are identified by a process for optimising the simulated and measured battery behaviour.

The implementation of parametered models in software environments, such as Matlab/Simulink, is normally carried out using a script. Heat flows in a 3D environment are calculated using a CFD simulation (ANSYS Fluent).
