A Real-time Performance Monitoring of IoT-based on Lithium-Ion Battery Pack

One of the newest battery technologies widely used for various applications is the lithium-ion battery. The performance of lithium-ion batteries must be maintained to get maximum battery life. For this reason, a real-time lithium-ion battery performance monitoring system is needed so that lithium-ion batteries have a long life. This paper proposes to create a lithium-ion battery pack (12 V, 60Ah) monitoring system using IoT-based. The parameter of a lithium-ion battery can be monitored, such as battery capacity, voltage, current, and power. Real-time data is updated automatically per minute and is visible on the LCD in the battery case and smartphone. As a result, the built-in monitor system successfully monitors battery performance during charging and discharging. The battery charging process using current 4A took 18 hours, and discharging process with a load of 50 W took 14 hours. The minimum and maximum voltage are 9.91 V when the battery is empty and 12.24 V when the battery is full. The system will provide notification via the smartphone if the battery condition is low. In addition, electrical parameter data is recorded via the google spreadsheet and Blynk application.
