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.
The presentation will take place in the e-mobility forum (Hall 6-326) on Tuesday 16.5 and Wednesday 17.5, at 14:30-15:00 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 12 V 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.
