Le transfert de charges est réalisé en utilisant un élément de batterie de moindre capacité qui est connecté, de manière séquentielle, aux autres éléments de la batterie. Il n’agit pas seul, l’énergie, lors du transfert, s’ajoute à l’énergie totale de la batterie d’accumulateurs, ce qui accroît sa capacité.<\/h2>\n

Dans la puce, sont inclus les circuits de séquençage, de contrôle de FET N externes de forte tension, de gestion de la tension et de protection. Elle est conçue pour fonctionner de manière autonome et ne nécessite ni microprocesseur, ni autre circuit de contrôle. Avec cet équilibreur, un élément de batterie peut être remplacé et rapidement équilibré avec les éléments restants. Il est bien adapté pour des applications telles que les systèmes de sauvegarde pour les télécommunications, les systèmes domestiques de sauvegarde alimentés sur batterie, les dispositifs des véhicules électriques et d’éclairage industriel. <\/h2>\n

Ce dispositif utilise un élément auxiliaire de batterie de stockage pour transférer la charge vers, ou à partir de chaque élément de la batterie. Une broche MODE donne accès à un choix de fonctionnement en mode à temporisation ou en mode continu. Dans le premier cas, une fois l’équilibrage réalisé, le circuit commute en un état de plus faible charge pendant une durée programmée et rééquilibre périodiquement les éléments de la batterie. En mode continu, l’équilibrage se poursuit même lorsque les éléments sont chargés à la tension finale programmée. En outre, plusieurs composants peuvent s’ajouter pour assurer l’équilibrage de batteries d’accumulateurs en série de tension plus élevée.<\/h2>\n

Ce circuit équilibreur se présente en boîtier TSSOP de 38 broches, à performances thermiques renforcées et faible profil de 0,75 mm. Les classes E et I sont spécifiées pour un fonctionnement sur la gamme de températures de jonction de -40 °C à +125 °C. <\/p>\n<\/p>\n
