EVCS/workflows/victron-grid-hysteresis-v1.json
Tallagrand Thierry 84b9cfef8b Le reseau vient quand la maison demande plus que la batterie ne sait donner 
Quatre modules : le BMS annonce 100 A de decharge sous 51 V, soit
5,1 kW, quand la maison a deja pointe a 8 kW en cuisinant. Contacteur
ouvert, la batterie est seule et se fait tirer au-dela de sa limite.

Le declenchement porte sur la CHARGE MAISON, jamais sur le courant
batterie : fermer le contacteur fait chuter ce courant, donc s'en
servir comme critere de relachement ferait que la decision detruirait
sa propre cause. Fermeture a 80 % du plafond, relachement sous 50 %,
les deux seuils derives du plafond annonce par le BMS - ils suivront
donc le parc sans qu'on y touche.

Les tests ont revele un vrai defaut au passage : les trois coupures
immediates s'executent avant la cascade et auraient ouvert le
contacteur que la regle venait de fermer. Elles cedent desormais
devant la charge maison. Preuve par mutation : sans cette garde, un
scenario tombe.

Plafond illisible => regle inerte, comportement historique intact.
11/11.
