  • Cell level based battery model

    In KULI the user can choose between different ways how to model a battery. They mainly differ in the necessary amount of input data, the effort for the creation of the model and also in the level of detail of the results.
    This example shows in a detailed way how to model an energy storage. The battery contains cells & modules, as well as the multi-dimensional housing. The electric model is based on a cell level R-C model, which also considers the capacitive behavior.
     

    This example demonstrates the advanced modeling concept for a thermal-electric battery model. Each of the 8 modules is housed in the battery and includes 12 cells (overall 96 li-Ion pouch cells including the cooling plates). Beside the thermal inertias of the cells themselves, also a multi-directional model of the housing is included. Each side of the housing as well as the cells can be connected by heat conduction. To simulate the electric behavior, a cell based R-C model is used. On the one hand this model describes the electric properties (like SOC, open cell voltage, ..), on the other hand  the thermal behavior of the cells. Beside averaged values, each cell temperature can be accessed. For that reason the model shows excellent opportunities for battery layout design and of course also for the development of the battery cooling system.

    Usable from release: KULI 9.1-0.01
