Vehicles with electric drive trains place completely new demands on measurement and testing technology. The Fraunhofer IISB test center in Erlangen, Germany, offers a unique infrastructure tailored specifically to these requirements, in which individual components from electric vehicles to complete vehicles can be measured and optimized.
The test center includes test benches for electric drives, energy storage, electrical-thermal reliability and electromagnetic compatibility.
The core element is a roller test bench in a temperature-controlled test room. This means that tests can also be carried out on complete vehicles, e.g. on the range under extreme ambient conditions. One development goal is to minimize the total energy requirements of the vehicles through optimized thermal management, highly efficient power electronics and energy-efficient auxiliary units.
Each individual test bench of the test centre has access to an extensive central infrastructure to supply the test specimen.
This includes a highly dynamic and energy-efficient DC source that can be regenerated from the mains as well as an efficient coolant supply (-40 °C to +115 °C).
The central infrastructure is integrated into the automation of each individual test bench via PROFIBUS.
