Title (EN) BATTERY WITH CHARGE CONTROL CIRCUITRY
(FR) BATTERIE A CIRCUIT DE CONTROLE DE CHARGE
Abstract:
(EN) Circuitry is added to charge storage devices including batteries which creates or enhances a minus delta V type of termination signal pattern to trigger a battery charger to terminate the battery charging. Circuitry, which is responsive either to a voltage or to a temperature, causes a switch to connect a load across the terminals of a battery to cause a voltage drop. The voltage drop triggers circuitry within the battery charger to terminate charging. For some applications, additional circuitry is added to cause a second switch to open to remove the load from the terminals upon the occurrence of a second specified event. The second specified event is defined by a specified voltage, temperature, or elaspsed time value.
(FR) L'invention porte sur l'adjonction à des dispositifs de stockage de charges, y compris des batteries, de circuits qui créent ou accroissent un signal d'achèvement de type moins $g(D)V commandant le chargeur de batterie pour mettre fin à la charge. Lesdits circuits, qui réagissent à la tension ou à la température, font basculer un commutateur qui place entre les bornes de la batterie une charge qui fait chuter la tension, la chute de tension actionnant les circuits internes du chargeur de batterie pour mettre fin à la charge. Dans certaines applications, des circuits supplémentaires entraînent l'ouverture d'un deuxième commutateur qui déconnecte la charge placée entre les bornes lorsque se produit deuxième événement qui peut être une tension, une température ou une durée spécifiées.
