Title (EN) METHOD FOR MEASURING THE CHARGE STATE OF AN ACCUMULATOR AND DEVICE FOR IMPLEMENTING SUCH METHOD
(FR) PROCEDE DE MESURE DE L"ETAT DE CHARGE D"UN ACCUMULATEUR ET DISPOSITIF POUR LA MISE EN OEUVRE DE CE PROCEDE
Abstract: front page image
(EN)The method consists in measuring the temporary voltage drop across the accumulator terminals upon an important current flow. The measuring device of such maximum voltage drop comprises a first maximum detector (43) feeding a voltmeter (42) and connected to the output terminal of a subtractor (44) of which the so-called reverser input is connected to the accumulator through a filter (45) and of which the so-called non-reverser input is connected to the accumulator through a second maximum detector (46). Application to the measurement of the charge state of an accumulator.
(FR)Le procede consiste a mesurer la chute de tension temporaire aux bornes de l"accumulateur lors du debit d"un courant important. Le dispositif de mesure de cette chute de tension maximale comprend un premier detecteur de maximum (43) alimentant un voltmetre (42) et connecte a la borne de sortie d"un soustracteur (44) dont l"entree dite inverseuse est connectee a l"accumulateur par l"intermediaire d"un filtre (45) et dont l"entree dite non inverseuse est connectee a l"accumulateur par l"intermediaire d"un second detecteur de maximum (46). Application a la mesure de l"etat de charge d"un accumulateur.
