Abstract

La présente concerne un bloc-piles utilisable quand il est difficile de recharger une pile spécialisée secondaire dans un terminal portable. Le bloc-piles est fixé dans une section de montage de pile dans un téléphone cellulaire portable. Dans le bloc-piles, des accumulateurs alcalins sont connectés en série. Ces accumulateurs génèrent des forces électromotrices ayant une tension (3 V) inférieure à celle de la pile spécialisée secondaire. Un circuit de source d'alimentation dispose d'un convertisseur c.c./c.c. de type suralimentation qui amplifie la tension des accumulateurs alcalins connectés en série à un niveau identique à celui de la pile spécialisée secondaire (p. ex. 4,5 V), et fournit une tension relevée. Un condensateur à double couche électrique peut fournir une alimentation stable à un circuit interne dans lequel la consommation d'électricité augmente ou diminue par rafales, il est chargé par l'application d'une sortie du circuit de source d'alimentation et il emmagasine l'énergie.
