Bonjour tout le monde,
je souhaite fabriquer un panneau de signalisation avec des leds, et pour ca, j'ai:
- 165 LED de 5mm RGB:
P = (3.4 * 0.02) * 165 = 11.22W
NB: je vais alimenter toutes les leds avec 12V + une resistance de 1
KΩ qur chaque broches anodes (est ce qu'il y a un risque que les leds crament),
Valeur de resistance:
Résistance 1/4W 60 Valeurs Précision 1% - 1 KΩ je ne suis pas sur est ce que 1/4W est bien 0.25W qui sera dissipé par une resistance? si c'est bein ca c'est grave car pour 165leds = 41.25W
- Arduino Nano. P = 5 * 0.02 = 0.1W (5V sera régulée avec LM7805 et des condensateur céramique 100nF et chimique de 100uF dont je connais pas la puissance dessipée)

on a U = R * I -> I = U/R = 12/150 = 0.08A donc P = 0.08 * 12 = 0.96W donc pour 2LDR = 1.92W
- Pour la batterie je récupere des piles 18650 des vieux batteries de pc portable (je compte mettre 3S et 5P tout depand de l'amperage qui ne doit pas depasser 20A).
- Pour charger la batterie j'opte pour un BMS (3S 20A 11.1V).
Question 1:
C'est quoi le PV adéquat pour une autonomie de 13H tout sachant que le soleil chez nous et de 7h.
J'ai une contrainte de l'espace pour les PV.
Question 2:
Est ce qu'avec le BMS je peux charger la batterie sans avoir aucun risque.
Par avance merci
