Design and Implementation of Battery Management System Using Passive Cell Balancing, interfacing with Blynk IoT

  • Unique Paper ID: 184346
  • PageNo: 1216-1222
  • Abstract:
  • Battery Management Systems (BMS) are pivotal for the safety, efficiency, and lifespan of Lithium-ion (Li-ion) batteries in electric vehicles (EVs) and energy storage systems. This work details the design and practical implementation of a BMS employing passive cell balancing and Blynk IoT-based interfacing for real-time monitoring and control. The system architecture integrates a boost converter, managed by an Adaptive Sliding Mode Controller (ASMC) through MATLAB/Simulink modeling. For hardware realization, ESP32 serves as the main controller, coordinating with sensors (ADS1115, INA219, DHT11, flame sensor) and actuators (relay modules) to achieve automatic cell balancing and protective functions. Wireless connectivity via Blynk IoT enables remote observation and management of battery parameters, enhancing system intelligence and user accessibility. Experimental results confirm that the proposed approach provides efficient cell balancing, robust protection, and high reliability for battery storage applications.
