Methods and systems for constructing a battery, the battery including at least two energy storage sections connected in parallel to a common module power bus, the energy storage sections including at least one battery cell and at least one section disconnect device capable of disconnecting the at least two energy sections from the module power bus, and, a section protection device to control the section disconnect device based on data from the energy storage sections. In an embodiment, the battery can include at least two battery modules connected in series using an interlock signal, where the battery modules include a module protection device having an interlock signal controller and fault logic for controlling the interlock signal controller, such that the modules can control the interlock signal and hence a disconnect device that receives the interlock signal and is connected between the modules and a load and/or charger.

L'invention concerne des procédés et des systèmes de construction d'une batterie, cette batterie comprenant au moins deux sections de stockage d'énergie connectées en parallèle à un bus de puissance commun du module, les sections de stockage d'énergie comportant au moins une cellule d'accumulateur et au moins un dispositif de déconnexion de section permettant de déconnecter les deux sections d'énergie du bus de puissance du module, et un dispositif de protection de section destiné à commander le dispositif de déconnexion de section en fonction de données provenant des sections de stockage d'énergie. Dans un mode de réalisation, la batterie peut comprendre au moins deux modules d'accumulateurs connectés en série au moyen d'un signal de verrouillage, les modules d'accumulateurs comprenant un dispositif de protection de module comportant une unité de commande de signal de verrouillage et un circuit de logique d'erreur, destiné à réguler cette unité de commande, de façon que les modules puissent commander le signal de verrouillage et donc un dispositif de déconnexion, qui reçoit le signal de verrouillage, et qui est connecté entre les modules et une charge, et/ou un chargeur.
