Eine direkte Messung wäre zB. theoretisch möglich indem man zunächst die Spannung und dann den Kurzschlussstrom misst. Dieses Verfahren ist allerdings ziemlich brachial und es besteht die Gefahr, dass dadurch das Multimeter zerstört wird. Ausserdem fliessen im Moment des Kurzschlusses gewaltige Mengen an Strom so das sich die Zelle binnen kürzester Zeit entlädt und sich somit der innere Ladungszustand fortlaufend ändert.<br /> <br /> <br /> Darum wollen wir hier eine Anleitung geben, wie es mit der Messung über einen Lastwiderstand und entsprechenden Berechnungen sicherer und genauer geht.<br /> <br /> Dazu ist es sinnvoll, den Unterschied zwischen Klemmenspannung und Leerlaufspannung zu verstehen [https://de.wikipedia.org/wiki/Klemmenspannung].<br /> <br /> <br /> &lt;gallery widths=&quot;640&quot; heights=&quot;480&quot; perrow=&quot;2&gt;<br /> File:<br /> File:<br /> File:<br /> &lt;/gallery&gt;</div>
