Due to the increasing demand for Electric Vehicles (EVs) worldwide is an implication of economic-technological efforts to reduce fossil fuel challenges. Energy storage which powers electric vehicles is a very important component. Battery packs used as energy storage for electric vehicles use many battery cells connected in series and in parallel. These battery cells require a close monitoring and management system while operating in an electric vehicle. Such a system, called the Battery Management System (BMS). BMS and battery packs play a very important role for EVs to become the best technical and commercial alternative to gasoline-based vehicles. BMS improves battery performance, and extends battery life while ensuring a safe operating range. Cell voltage balancing with State of Charge (SOC) monitoring is part of an important function of BMS. This paper focuses on the design and analysis of a passive cell balancing method for lithium-ion (Li-Ion) batteries based on the Arduino-Nano controller. This paper also deals with the simulation to demonstrate the SOC estimation using Coulomb counting method and passive cell balancing mechanism using MATLAB and results were analyzed.
