Abstract

L'invention concerne un procédé de fonctionnement d'un système de stockage d'énergie électrique comprenant au moins une unité de stockage d'énergie électrique. Le procédé comprend les étapes suivantes. Une valeur de compteur (TIM) est modifiée après qu'un premier seuil de tension prédéfini (UTHR1) a été franchi vers le haut ou vers le bas par une valeur de tension déterminée (UESU) du système de stockage d'énergie électrique. Une première valeur limite de tension prédéterminée (ULIM1) est modifiée après qu'une première valeur de seuil de compteur prédéfinie a été atteinte par la valeur de compteur (TIM). Puis, le système de stockage d'énergie électrique est commandé de telle sorte que la première valeur limite de tension (ULIM1) modifiée ne soit pas dépassée vers le haut ou vers le bas. En outre l'invention concerne un support de stockage lisible par machine, une unité de commande électronique, un système de stockage d'énergie électrique et leur utilisation correspondante dans des véhicules électriques, y compris des véhicules hybrides, dans des systèmes de stockage d'énergie électrique fixes et dans des outils à main électriques.
