Simulation & Modeling

Cutting-edge simulation techniques for battery research and development

The Fraunhofer Battery Alliance uses state-of-the-art characterization and simulation methods to precisely map the properties of batteries from the atomic scale through to their behavior in the powertrain. This includes quantum chemical methods for material characterization, physical continuum models for cell design and real-time-capable battery models for integration into battery management systems (BMS) and hardware-in-the-loop (HIL) systems. Our member institutes develop detailed and analogous models for strength analysis and optimize cell structures for operational safety and crash safety. The models are used for simulations to test the behavior of battery modules and systems in advance. We also analyze and dimension energy storage systems, determine optimal circuit variations and develop innovative BMS for monitoring and diagnosing battery conditions

Our offer

  • Physical model development from the quantum mechanical level through to the whole battery
  • Analysis of the influence of nanostructures on material parameters
