Abstract
(DE)
Die vorliegende Erfindung betrifft ein Verfahren zum Betreiben eines elektrischen Energiespeichers, der eine Speicherzelle zum Speichern von elektrischer Energie und eine Steuereinheit umfasst, wobei ein Sicherheitsschalter vorgesehen ist, der eingerichtet ist, eine elektrische Leitung des elektrischen Energiespeichers zu unterbrechen, wobei ein Strom, der durch die elektrische Leitung fließt, erfasst wird und eine Betätigung des Sicherheitsschalters nur dann erfolgt, wenn der Strom unterhalb eines vorgebbaren Schwellwerts liegt.
(EN)
The invention relates to a method for operating an electrical energy store, comprising a storage cell for storing electrical energy and a control unit, wherein a safety switch is provided which is designed to interrupt an electrical line of the electrical energy store, wherein a current flowing through the electrical line is detected and an actuation of the safety switch only occurs if the current is below a predefinable threshold value.
(FR)
L’invention concerne un procédé de fonctionnement d’un accumulateur d’énergie électrique comprenant un élément d’accumulateur destiné à accumuler de l’énergie électrique et une unité de commande, un interrupteur de sécurité étant conçu pour déconnecter un conducteur électrique de l’accumulateur d’énergie électrique. Un courant traversant le conducteur électrique est détecté et l’interrupteur de sécurité est actionné uniquement si la valeur du courant est inférieure à une valeur seuil pouvant être spécifiée.
