IoT-Based Multiple Battery Charging System Using a Single Charger

The IoT-Based Multiple Battery Charging System Using a Single Charger is designed to charge multiple batteries using one common charger. The ESP32 monitors the voltage, charging current, temperature, and charging status of each battery and automatically selects the appropriate battery for charging.

When one battery reaches the required charging level, the system automatically disconnects it and switches the charger to the next battery. All battery parameters and charging status can be monitored remotely through an IoT web dashboard.
