Abstract

Viene proposto un dispositivo per determinare lo stato di carica di una batteria ricaricabile (11). Un volume di conteggio, rappresentante questo stato di carica, di un dispositivo contatore elettronico (17), durante il funzionamento di un utilizzatore (12, 13) allacciato alla batteria (11), viene variato proporzionalmente in una prima direzione. Sono inoltre previsti mezzi (16) per la variazione proporzionale di questo volume di conteggio nella direzione opposta, con il caricamento della batteria (11). In tal modo si può tener conto anche di cariche parziali della batteria e di contemporanee operazioni di scarica e di carica in caso di simulazione (figura 1).A device is proposed for determining the state of charge of a rechargeable battery (11). A counting volume, representing this state of charge, of an electronic counter device (17), during the operation of a user (12, 13) connected to the battery (11), is proportionally varied in a first direction. Means (16) are also provided for the proportional variation of this counting volume in the opposite direction, with the charging of the battery (11). In this way it is also possible to take into account partial battery charges and simultaneous discharge and charge operations in the event of simulation (figure 1).
