The automotive industry is in transformation. New generation vehicles deploying hybrid (HEV), fully electric (EV), and Hydrogen fuel cells are presenting significant challenges to automotive engineers. The complexity of the vehicle has increased significantly in the past decades, with higher performance components and digital control through ECU development. This has started a design revolution in the industry which requires detailed modelling and simulation steps prior to committing to physical production prototypes. With new generation HEV vehicles, the need for advanced physical modelling solutions is considerably greater due to increasing system complexity, and the battery is becoming one of the most critical components in alternative power source route map for the next 10 – 15 years. The Hydrogen fuel cell also features in these plans, and the capability to model down to the chemical reaction level is unique.

Using Dymola as the tool of choice in modelling and simulating hybrid electric vehicle (HEV), fully electric vehicle (EV) applications, and including Hydrogen Fuel Cells, allows the engineer the freedom to verify and validate differing optimised approaches quickly and cost effectively. These standard models can then be added to system models for HEV and EV applications as required. Conventional lead-acid, but also NiMH and Lithium battery models can be represented.

With an intuitive multi-physical modelling environment, and powerful multi-body modelling technology, the range of Dymola modelling and simulation tools are uniquely suited to optimising and enhancing the development batteries and fuel cells down to the chemical reaction level. Dymola makes the development and application of the necessary models quicker and more accurate through verified component based model reuse.

Dymola and the additional libraries are ideal for model development and analysis, and dramatically reduce the time and cost of up-front analysis, virtual prototyping, and parameter optimization of system designs using symbolic manipulation.
