Selected Fraunhofer projects in the field of electromobility and safety

"hyPowerRange" – Hybrid energy storage systems for electric vehicles

In the “hyPowerRange” project, the Fraunhofer Institute for Wind Energy and Energy System Technology IWES is working together with its partners on direct coupled hybrid energy storage for electric vehicles. The aim is to unite the long range of high-energy cells with the high capacity of the high-performance cells in a modular system. In this project, the Fraunhofer IWES is focusing particularly on the electrical design of the energy storage device and is conducting battery simulations, working out operations strategies and testing the entire system in a vehicle demonstrator.

"Battery Bus Markkleeberg – eBus Batterfly"

To test the charging technology and corresponding charging infrastructure, the “Battery Bus Markkleeberg - eBus Batterfly” project is being conducted by the Fraunhofer Institute for Transportation and Infrastructure Systems IVI. As part of the project, the bus fleet in Markkleeberg has been increased by the introduction of two fully-electric buses. Their introduction into mass transit requires the development of concepts allowing the onboard bus batteries to be recharged intermittently at bus stops.

"OptiFeLio" – Optimized design and production concepts for lithium-ion battery housings

In the “OptiFeLio” project, the consortium partners are working to optimize the design and production concepts for the manufacture of lithium-ion battery housings in order to reduce production process costs for battery housings, which remain significant. Additionally, integrating sensors into the housings could make it possible to detect important cell parameters, and enable early detection and repair of malfunctions. Taking safety aspects into account and conducting safety tests are part and parcel of the work at the Fraunhofer ICT in the course of the project.

"ProTrak" – Test stand for high-precision coulometry

The calendar lifespan (aging) and cycle stability of a battery are also influenced, among other things, by the way batteries are stored, and by the initial charging and discharging, the pace of training. However, because these tests and procedures are expensive and time-consuming, the Fraunhofer Institute for Solar Energy Systems ISE is working in its “ProTrak” project to optimize them with a view to significantly lower the costs of the batteries.

"BEMA 2020" companion measure

In the “BEMA 2020” companion measure to the funding initiative entitled “Battery materials for future electromobile and stationary applications (Battery 2020)”, the cumulative battery expertise from this initiative is being gathered and combined with research activities, both domestically and abroad. The Fraunhofer Institute for Systems and Innovation Research ISI is involved in the companion measure and supports the Federal Ministry for Education and Research (BMBF: Bundesministerium für Bildung und Forschung) through monitoring and road-mapping processes, in order to develop research strategies in the fields of batteries, electromobility and stationary storage.

Battery Safety Lab

Battery and Sensor Test Center (BST)

The Battery and Sensor Test Center is a service and testing facility operated by Fraunhofer Institute for Telecommunications, Heinrich-Hertz-Institut HHI in Goslar in collaboration with Clausthal University of Technology. The major topic of activity is battery safety enhancement.

ZSZ-e Center for System Reliability

This Fraunhofer LBF facility focuses on research and development of traction components for electric vehicles.
