Circuit arrangement that has an energy source that can provide a charging voltage for charging an electrical energy storage unit in a charging circuit when it is connected to an energy supply, wherein it is possible to represent the charging voltage using an alternating quantity, and that has a capacitor circuit having a first capacitor element, a first valve element, and the energy source, wherein the first capacitor element is charged by the energy source via the first valve element if the charging voltage is negative, so that, if the charging voltage is positive, the voltage over the first capacitor element has the same orientation in the ca-pacitor circuit, in terms of sign, as the charging voltage, and the voltage over the capacitor element and the energy source can be detected using a control apparatus.

La présente invention concerne un agencement de circuit comportant : une source d'énergie pouvant fournir une tension de charge pour charger une unité de stockage d'énergie électrique dans un circuit de charge lors de sa connexion à une source d'énergie, avec possibilité de représenter la tension de charge en utilisant une grandeur alternative ; et un circuit à capacités comportant un premier élément condensateur, un premier élément valve, et la source d'énergie, le premier élément condensateur étant chargé par la source d'énergie via le premier élément valve si la tension de charge est négative, de sorte que, si la tension de charge est positive, la tension sur le premier élément condensateur a la même orientation dans le circuit à capacités, en terme de signe, que la tension de charge, et la tension sur l'élément condensateur et la source d'énergie peut être détectée en utilisant un appareil de contrôle.
