Title (EN) VOLTAGE DETECTION APPARATUS AND METHOD OF REDUCING DISPERSION OF DARK CURRENTS
(FR) APPAREIL DE DÉTECTION DE TENSION ET PROCÉDÉ DE RÉDUCTION DE DISPERSION DE COURANTS D'OBSCURITÉ
Abstract: front page image
(EN)A voltage detection apparatus includes a plurality of voltage detection units, each of which detects cell voltages of plural cells in each of blocks in a battery module. Each of blocks includes the plural cells connected in series. The plurality of voltage detection units are respectively supplied with power via power supply lines connected to the blocks. The plurality of voltage detection units are respectively provided with a plurality of current increase units for increasing dark currents so that the dark currents flowing through the power supply lines respectively become a same target value.
(FR)L'invention concerne un appareil de détection de tension comprenant une pluralité d'unités de détection de tension, chacune d'elles détectant les tensions de cellule de plusieurs cellules dans chacun des blocs d'un module de batterie. Chacun des blocs comprend plusieurs cellules montées en série. La pluralité d'unités de détection de tension sont respectivement alimentées en électricité via des lignes d'alimentation électrique connectées aux blocs ; et sont respectivement équipées d'une pluralité d'unités d'augmentation de courant pour augmenter les courants d'obscurité de telle sorte que les courants d'obscurité s'écoulant respectivement via les lignes d'alimentation électrique deviennent une même valeur cible.
