Abstract

L'invention porte sur un procédé de connexion consistant à combiner des piles à relativement faible puissance et relativement faible tension en un système de piles. Les piles à relativement faible puissance sont connectées d'abord en série et ensuite en parallèle de manière à former une combinaison de piles. En même temps, toutes les deux piles connectées en série sont considérées comme étant une unité de combinaison minimale, et un signal central de chaque unité de combinaison minimale est acheminé vers un système de gestion de piles. Les deux bornes de l'unité de combinaison minimale, à l'exception des pôles positif et négatif de la combinaison de piles, sont connectées à des signaux de référence correspondants dans la même rangée par l'intermédiaire de leurs fusibles respectifs. Les fusibles ont une fonction de protection contre des défauts graves de la pile correspondante.
