Im Labor der Professur Mess- und Sensortechnik der Technischen Universität Chemnitz füllen sie halbe Schränke: Anlagen zur Impedanzspektroskopie, mit denen man unter anderem untersuchen kann, wie lange Batterien leistungsfähig sind. Der aktuelle Stolz der Elektrotechniker aber passt auf eine zehn mal fünf Zentimeter große Leiterplatte - den Chemnitzer Forschern ist es gelungen, die bisher Platz raubende Technik in handliches Format zu bringen und damit die Anwendung der Impedanzspektroskopie zur Batteriediagnose in Elektrofahrzeugen zu ermöglichen. Das kleine und preiswerte System kann künftig eine wesentlich bessere Ausnutzung der Batterieleistung ermöglichen. Es ist für alle Batterietypen anwendbar.
