Title (EN) TRANSPORTATION MEANS, DEVICE AND METHOD FOR DETERMINING A VOLTAGE OF A CELL OF A STRING OF MULTIPLE CELLS CONNECTED IN SERIES OF AN ELECTRO-CHEMICAL ENERGY STORAGE MEANS
(FR) MOYEN DE DÉPLACEMENT, DISPOSITIF ET PROCÉDÉ DE DÉTERMINATION D'UNE TENSION D'UNE CELLULE D'UNE CHAÎNE DE PLUSIEURS CELLULES CONNECTÉES EN SÉRIE D'UN ACCUMULATEUR D'ÉNERGIE ÉLECTROCHIMIQUE

Abstract:
(EN) The invention relates to a transportation means, a device and a method for determining a voltage of a cell (1b) of a string (I) of multiple cells (1a, 1b, 1c, 1d, 1e, 1f) connected in series of an electro-chemical energy storage means. The method comprises the following steps: supplying, in a duty cycle, an input of a low-pass filter (11) with an input voltage, the cell (1b) being at least involved in the production of said voltage; adjusting the duty cycle in such a way that the output voltage reaches a predefined value across an output of the low-pass filter (11); and determining the voltage of the cell (1b) from the adjusted duty cycle.
(FR) L'invention concerne un moyen de déplacement, un dispositif et un procédé de détermination d'une tension d'une cellule (1b) d'une chaîne (I) de plusieurs cellules (1a, 1b, 1c, 1d, 1e, 1f) connectées en série d'un accumulateur d'énergie électrochimique. Le procédé comporte les étapes consistant à : appliquer, suivant un rapport cyclique, une tension d'entrée à l'entrée d'un filtre passe-bas (11), tension d'entrée à l'établissement de laquelle participe au moins la cellule (1b), régler le rapport cyclique de telle sorte que la tension de sortie atteigne une valeur prédéfinie par le biais d'une sortie du filtre passe-bas (11), et déterminer la tension de la cellule (1b) à partir du rapport cyclique réglé.
(DE) Es werden ein Fortbewegungsmittel, eine Vorrichtung sowie ein Verfahren zur Ermittlung einer Spannung einer Zelle (1b) eines Strangs (I) mehrerer in Reihe geschalteter Zellen (1a, 1b, 1c, 1d, 1e, 1f) eines elektrochemischen Energiespeichers vorgeschlagen. Das Verfahren umfasst die Schritte: Beaufschlagen eines Eingangs eines Tiefpassfilters (11) mit einer Eingangsspannung, an deren Zustandekommen die Zelle (1b) zumindest beteiligt ist, in einem Tastverhältnis, Einstellen des Tastverhältnisses derart, dass die Ausgangsspannung über einem Ausgang des Tiefpassfilters (11) einen vordefinierten Wert erreicht, und Ermitteln der Spannung der Zelle (1b) aus dem eingestellten Tastverhältnis.
