At the PCIM (16th-18th May in Nuremberg), Rutronik together with the Chemnitz University of Technology will present their research project Expanding monitoring and analysis functions in the battery management system based on impedance spectroscopy. It allows impedance spectroscopy to be used with embedded systems as well for the first time and opens up new possibilities regarding range forecasts for electric mobility.

Impedance spectroscopy enables more accurate analysis and diagnosis of battery systems than the procedure currently used, thus ensuring reliable forecasts e.g. regarding their RUL (remaining useful life) and State-of-Health (SoH). This means that range forecasts for electric vehicles can be determined on a sound basis.

Up to now, the use of impedance spectroscopy for lithium-ion batteries has been confined to laboratory environments. The research project has now also applied the method to embedded systems for the first time. It is particularly interesting for mobile systems, above all in electric mobility, for professional tools, mobile robots, but also for medical devices and UPS systems.

Specialist presentation
The presentation will take place in the e-mobility forum (hall 6-326) on Tuesday 16th May and Wednesday 17th May, at 14:30 and 15:00 respectively.

Demonstrator (Rutronik stand 7-226)
At the Rutronik stand in hall 7, booth 226, a demonstrator of an embedded impedance measuring system for a 12V lithium-ion battery stack will prove the method’s industrial applications. Scientists from Chemnitz University of Technology as well as Andreas Mangler, who supervises the project on behalf of Rutronik, will be available for technical discussions.
