STORAGE BATTERY INCLUDING A DISCONNECTOR HAVING A FUSE AND AN EXPLOSIVE WITH A HEAT BRIDGE PROVIDING CONTINUITY OF SERVICE IN THE EVENT OF A MALFUNCTION

1. A storage battery, comprising:first and second stages electrically connected in series, each stage including at least first, second, and third accumulator electrically connected in parallel;
at least first and second disconnectors by which the first, second, and third accumulators of the first stage are connected in parallel and by which the first, second, and third accumulators of the second stage are connected in parallel, each of the disconnectors including a first electrode and a second electrode,
wherein each of the first and second disconnectors includes:
a fuse including a conducting link connected in series between the first and second electrodes and including a fusible portion, and
an explosive, with a heat bridge between the fuse and the explosive so that heating of the fuse forms a detonator initiating the explosion of the explosive, the explosion of the explosive causing the conducting link to open, the explosive having an explosion initiation temperature that is lower than the melting point of the fusible portion,
wherein the explosion of the explosive of one of the first and second disconnectors does not affect the status of the conducting link of the other one of the first and second disconnectors.
