(FR) INDICATEUR D'ENERGIE
Abstract
(EN)
An energy gauge for indicating the amount of residual power available from a battery includes means for storing a predetermined value of a power parameter indicative of full battery capacity, means for determining the instantaneous power consumption indicated by the parameter, means for integrating the power consumption indicative of the parameter since commencement of use of the battery, means for subtracting the integrated consumption from the stored value of full capacity to provide a value of power remaining, and readout means for providing a representation of the power remaining.
(FR)
L'invention concerne un indicateur d'énergie indiquant la quantité de courant résiduel disponible d'une batterie. Ledit indicateur comprend un système de stockage d'une valeur prédéterminée d'indication de paramètre de puissance, indiquant la capacité de batterie pleine, un système de détermination de la consommation d'électricité instantanée indiquée par le paramètre, un système d'intégration de la consommation d'électricité indicative du paramètre depuis le début d'utilisation de la batterie, un système d'extraction de la consommation intégrée à partir des valeurs de pleine capacité stockées afin de fournir une valeur d'électricité restante, ainsi qu'un système d'affichage destiné à afficher une représentation de l'électricité restante.
