Smart Charger Monitoring System using Arduino

Download Project Document/Synopsis

A battery charger, or recharger, is a device used to transfer energy into a secondary cell or rechargeable battery by forcing an electric current through it. The charging protocol depends on the size and type of the battery being charged. A smart battery charger is mainly a switch mode power supply that has the ability to communicate with smart battery packs, battery management system in order to control and monitor the charging process. This smart charger is powered using Arduino. This smart charging system can charge three battery of 12V at a time. It automatically disconnects a battery from the mains when the battery gets fully charged. It has auto power cut off system. Smart charger is mainly a switch mode power supply that has the ability to communicate with smart battery pack. It also continuously shows the battery charged percentage on the LCD display module.
