Vehicle integration

Fraunhofer currently offers three prototype vehicles as a testing platform, enabling tests under real-world conditions on the individual vehicle components developed within the framework of electromobility research projects, such as:

  • Electric drives
  • Battery systems
  • Conductive and inductive charge systems
  • DC/DC converters
  • Electric heating systems

For the fast and flexible integration of new components, the vehicles are fitted with in-house developed low voltage wiring systems with central wiring, freely programmable vehicle control units, and their own CAN-bus systems for additional components.

Both the integration of new components as well as their testing within the entire vehicle, e.g. at the ATP test site in Papenburg, offer essential insights into vehicle-related demands on the individual components. These insights flow directly back into the development process at Fraunhofer IFAM, for example for electric drives.

  • Definition and early-stage testing of communication interfaces between the entire system and the components
  • Design and verification of suitable operational strategies
  • Simulation of cases of error and testing of error approach strategies

Within the framework of a research project titled Dynamic Inductive Energy Transmission, an inductive charging system was integrated into an existing vehicle (FRECCO i). The charging capacity in motion and/or at a standstill amounts to up to 30 kW.

In the current research initiative known as Fraunhofer System Research Electromobility II, two air-cooled wheel hub drives were integrated into the front axle of the FRECCO R, which had already been fitted with wheel hub drives at the rear axle.
