Smart Battery Swapping and Safety Management System

In India the demand of EVs are continuously increasing as a necessity for the future, to efficiently implement this system we require proper charging infrastructure. To reduce the charging time of existing charging system we can use battery swapping system. This paper presents the development of a smart battery swapping system which is designed for two 3.7V 4Ah batteries. The system continuously monitors the SOC, battery temperature, and potential fire hazards. Using a DHT11 sensor for temperature tracking and flame detection, the system incorporates visual and audible alarms and relay control for safety. Additionally, the system sends SMS via SIM800L if any charging slot is empty, ensuring real-time management and efficient use.
