Battery Thermal Management Simulation – 1D+1D Electrochemical Battery and 3D Module Modeling on Vehicle System Level
Global concerns on sustainable energy use call for innovative energy conversion technologies. Batteries are key enablers for more sustainable mobility provided the availability of renewable energy sources. Batteries are integrated in battery electric, plug-in hybrid and hybrid electric vehicles. All these applications call for high energy and power density, long lifetime and highest safety. However, there are application-specific objectives like different load profiles and thus specific durability and safety criteria. A single design of a battery cell cannot optimally comply with all envisaged application areas. Tailoring battery designs to a specific application with the aim of approaching engineering limits represents a significant challenge. Virtual prototyping with predictive models is one key enabler to frontload the development process. This is important in the light of the outlined challenges, which cover a broad range of spatial and temporal scales.
