Abstract: (french)
Cet article porte sur un chargeur solaire de batteries à embarquer à bord d’un modèle de sac d’étudiant Android. C’est un nouveau dispositif multifonctions à base du microcontrôleur ESP32 conçu pour: a) la conversion d’énergie solaire en énergie électrique régulée pour la charge de batteries au Lithium-Polymère; b) l’acquisition numérique des données d’énergie électrique de charge de la batterie; c) la transmission Bluetooth de ces données d’énergie à un moniteur Android. Du côté de l’ESP32, le programme d’application requis pour l’acquisition de données et la configuration du serveur Bluetooth, est développé dans Arduino IDE-C++. Puis, du côté du terminal Android, un Smartphone équipé d’une application configurée sert de moniteur virtuel Android des données d’énergie de charge de la batterie alimentée. Enfin, un prototype expérimental du dispositif est réalisé est bien testé, puis les résultats d’essais obtenus et présentés sont très satisfaisants.
Author Keywords: Chargeur solaire de batterie, microcontrôleur ESP32, données d’énergie électrique, serveur Bluetooth, moniteur virtuel Android.
