Abstract

Es wird ein Verfahren zum Bestimmen einer Position eines Kolbens (5) innerhalb eines Kolbendruckspeichers (1) sowie ein entsprechend ausgebildeter Kolbendruckspeicher (1) beschrieben. In einem Gehäuse (3) befindet sich hierbei ein verlagerbarer Kolben (5). An dem elektrisch leitfähigen Gehäuse (3) ist eine Elektrodenanordnung (15) mit einer Vielzahl von 4-Punkt-Messung-Elektrodenpaaren (17) vorgesehen und dazu ausgebildet, eine Position des Kolbens (5) innerhalb des Gehäuses (3) durch Messen einer Verteilung eines elektrischen Widerstandes bzw. eines Potentials zwischen inneren Elektroden (21) bei Anlegen eines Stromes an äußere Elektroden (19) abhängig von einer Position entlang des Gehäuses (3) zu bestimmen. Die aufgrund der Messung der Potentialverteilung ermittelte Position des Kolbens kann zur Bestimmung oder Überprüfung eines Ladezustands des Kolbendruckspeichers (1) verwendet werden.
