Smart Charging System
This Smart Charging System discloses an IoT (Internet of Things) based Intelligent charging system for the existing multichemistry batteries as well as the upcoming batteries. The Charging system encompasses: The server device and the client device. The server device stores the different battery profiles and also inputs the specific battery profile to the user. Following that, the client device which is interfaced with the battery, charges it by controlling voltage and current from the AC input. The battery profiles are selected through the switches from the battery profile information menu displayed in the LCD. This whole system comprises of two parts: IOT section and charging section. The IoT section includes PC as server and the client section consists of a microcontroller and an EEPROM. The Server section has GUI to feed the charging algorithm of a particular battery profile.
The server and client devices are connected remotely by Wi-Fi connection. Both server and client are having Wi-Fi modules for the communication. The server Wi-Fi module is in AP (Access point) mode and the client in STA (Station) mode. The client copies the battery profiles data from the server to the EEPROM using microcontroller.
The charging module consist of microcontroller, buck circuit, switching circuit, current, voltage and temperature sensors, LCD, Switches and power supply module. The microcontroller downloads the battery profiles information from the EEPROM and adjusts the voltage and current by buck circuit based on the real time temperature, voltage and current sensor values. The switches selects the battery profiles and LCD shows the basic information like Battery profile list, percentage of Voltage, current etc.
