: This system allows for the monitoring of battery voltage and percentages in electric vehicles from any location worldwide. As is commonly understood, the battery is a crucial element in any system or product, as it supplies power to the entire structure. Therefore, it is essential to keep track of the battery's voltage level. It is well-known that a poor charging and discharging process can lead to battery damage or system malfunction. Most electrical and electronic devices are equipped with a Battery Management System (BMS). The BMS oversees various battery attributes, including voltage, current, temperature, and the automatic cut-off mechanism, to ensure the proper handling and storage of Lithium-Ion or Lithium Polymer batteries in vehicles. The BMS can assess the current battery condition and notify the user via a battery indicator. However, in this study, we utilized Internet of Things (IoT) technology to provide remote notifications to users. With the integration of IoT, users can now receive automatic updates. Users can check the battery status on their smartphones or computer dashboards from anywhere in the world. The Node MCU ESP8266 board is employed in an IoT-based Battery Monitoring Program to transmit battery status information to the Arduino IoT cloud. The IoT Cloud Panel displays the voltage level and battery percentage during both charging and discharging scenarios. All these processes are facilitated by software. Key words: Battery management system, state of charge, state of health, state of life.
