Fast electrical battery model builder for embedded systems

When designing embedded systems, industries need to correctly size the battery to guarantee the autonomy and the lifetime required for their application. However, for battery behavior simulation, there is often a lack of accurate and realistic models. To help efficiently the system designer, we propose a strategy in three steps: first by guiding the cell technology choice, second by calibrating battery size and third by proposing a methodology to build an electrical battery model. To obtain such a model rapidly, we have realized a Battery Model Builder (BMB) that automatically reads measurements and builds the model for variable temperature. The resulting model can be used to verify battery sizing or can be integrated for energy estimations of the whole system.
