IoT Based Battery Condition Monitoring System for Electric Trolley

Abstract

Electric trolleys are widely used for short-distance transportation in industries, hospitals, airports and warehouses due to their eco-friendly operation and low operating cost. The battery is the primary energy source and its performance directly affects the reliability, safety and efficiency of the trolley system. Lack of proper monitoring can lead to issues such as overcharging, deep discharge, overheating and unexpected battery failures. To overcome these challenges, this project presents an IoT Based Battery Condition Monitoring System for Electric Trolley that enables continuous real time monitoring of critical battery parameters including voltage, current (INA219), and temperature (DS18B20). Sensors integrated with a microcontroller (ESP8266) collect battery data and transmit it to an IoT platform for remote access, data logging and alert generation. This system allows users to track battery performance, detect abnormal conditions early and schedule predictive maintenance, thereby extending battery life and enhancing operational safety. The proposed solution improves reliability, reduces maintenance costs and ensures efficient operation of electric trolleys.
