Le tampon d'evenements, celui que lit un fabricant

Le BMS tient deux tampons distincts et je n'avais extrait que l'un
des deux. history echantillonne toutes les trente minutes sur cinq
semaines ; event n'enregistre que les declenchements, a la seconde,
et remonte jusqu'a mai 2025.

C'est le second qui porte la preuve : le 27/07 sur le module ...0319,
quatre declenchements en trois minutes, cellule haute a 3650 mV. Et
il couvre seize mois, donc il contient le moment ou ces cellules ont
ete abimees.

Premier ecart, sans aucune interpretation : les quatre modules du
pack recent totalisent 38 evenements depuis mai 2025 - 19, 12, 6 et
1. Le module abime en compte 805 a lui seul.

--tampon event ajoute au mode d'extraction distante. Le garde pose
plus tot a d'ailleurs fonctionne : un module a refuse de partir sans
code-barres plutot que de rendre un fichier anonyme.
