Abstract

Circuit de protection contre les surcharges pour des éléments rechargeables chargés en série et ayant une tension de charge avec maximum prédéterminé et une tension de circuit ouvert, comprenant: des diodes couplées sur chacun des éléments pour former un chemin de shuntage si la tension sur l'élément associé dépasse la tension de charge maximale; un circuit chargeur couplé aux bornes de la chaîne en série et appliquant un courant de charge dans un sens prédéterminé, la diode étant une diode électroluminescente (DEL) avec une tension directe sensiblement égale à la tension maximale autorisée, et le circuit chargeur comprend des moyens (R) de limitation du courant et/ou de la tension qui limitent le courant passant par la chaîne en série d'éléments de batterie au plus à une valeur qui correspond sensiblement à l'intensité de courant qui passe par la diode électroluminescente lorsque la tension maximale permise y est appliquée, la diode électroluminescente (DEL) étant sensiblement non conductrice lorsqu'une tension correspondant à la tension du circuit ouvert est appliquée dans un sens vers l'avant, la diode électroluminescente ne constituant pas de charge significative pour l'élément de batterie associé lorsqu'elle est stockée ou déchargée, et shuntant entièrement l'élément de batterie après que cet élément ait atteint un état de charge totale, avec indication visuelle que l'élément associé a été chargé.
