For many years, the Fraunhofer IVI has been working in projects on innovative propulsion systems for public transport. The focus is on fully-electric and hybrid propulsion systems.

The institute’s expertise is based on measurement studies in public transport vehicles, in-depth knowledge of vehicle engineering, especially in propulsion systems, and the technical realization of innovative propulsions in test vehicles (AutoTram®, AutoTram® Extra Grand, EDDA-Bus as fast-charging battery bus, plug-in hybrid bus SaxHybridPLUS).

The experience from the area of public transport vehicle engineering has been used to develop the institute’s own vehicle simulation model IVIsion. This model, which has already been applied in many projects, describes vehicles in complete detail. Precise component models are created for the interaction between vehicle, environment and road, drivetrain, energy storage, auxiliaries, air conditioning and heating as well as driver and passengers. These models are combined to one highly complex simulation model which helps, for instance, to achieve precise prognoses regarding the energy consumption of a vehicle-propulsion configuration under certain application conditions. This program is complemented by IVInet, which can deliver network-covering and optimized introduction concepts for battery buses even under consideration of frequent change of bus lines.

The system IVImon detects relevant state parameters of the battery storage and provides them in a user-friendly way via an API or a web interface.

Further tools are available for optimization and reduction of costs in ongoing operation, adding to the increased efficiency and durability of the vehicles.
