This thesis presents the modeling and simulation, electric vehicle battery energy management system utilizing a bidirectional power transfer approach within the Ethiopian context. The research addresses critical issues such as climate change, environmental pollution, and high energy costs associated with traditional fuel-powered vehicles. EVs are identified as sustainable alternatives capable of reducing carbon dioxide emissions and operational costs, particularly through enhanced energy management systems employing Vehicle-to-Grid technology. The study focuses on the enhactment of a two-way, EV battery charger that incorporates V2G and G2V power converter topologies. The primary objective is to minimize harmonic distortion by implementing an inductance-capacitance-inductance filter and an alpha-beta regulator in grid-side modeling and simulations using MATLAB R2021a. Key findings, harmonic distortion reduction the total harmonic distortion decreased from 62% to 35%. Battery discharge efficiency, in which the battery discharge energy levels improved from 99.74% to 99.99994%. Voltage loss minimization, during voltage loss battery discharge was reduced from 0.726% to 0.0107%. The best charger type a three-phase charger was selected as the most effective configuration, and an economical aspect is energy cost savings for EVs compared to traditional vehicles ranging from 97% to 99%. These outputs focus on the potential of EVs to transform Ethiopia's transportation system, promoting lower energy consumption and cost-effectiveness as sustainable solutions for the future.
