Abstract— To soar new miles the global mobility sector is considered ready for decarbonization by adopting technologies to improve efficiency, cost effectiveness and charging flexibility. Integration of electric vehicles (EVs) in mobility sector demands charging infrastructure which shall be cost-effective, reliable and supports charging in effective manner. Existing grid face challenges during power exchange and also requires technological innovations in developing future EVs charging network. Future charging networks must be incredibly flexible to changing energy demands in addition to being dependable and reasonably priced in order to facilitate the widespread deployment of EVs. The grid is subjected to extra demands as a result of EV charging, which can cause supply-demand imbalances, surges in peak demand, and voltage changes. With the use of MATLAB/Simulink (PS-Blockset), the system model has been created and simulated, allowing for a thorough assessment of its performance under various operating circumstances. The outcomes of the simulation have been thoroughly examined in order to evaluate factors like load balancing, energy efficiency, power flow optimization, and the general dependability of power transactions between loads, the grid, and storage resources. The results unequivocally show that the suggested approach optimizes bidirectional power flow to reduce strain on the current grid while simultaneously increasing the efficiency of EV charging. Additionally, by facilitating the incorporation of renewable sources and supporting efficient demand-side management, the system enhances grid sustainability and resilience. Because the current power networks were not built to support such dynamic and bi-directional energy exchanges, they frequently struggle to integrate a large number of EVs seamlessly. This may require transmission grid expansion, management of demand-supply gap and scaling of energy storage systems. This paper proposes a grid supported EV charging system which maintain power exchange to/ from battery storage and utilizes local sources to cater EV charging requirement. The system offers flexible charging options at various charging levels of EV. The proposed system has been simulated in Matlab/ PS-Blockset and attained results are rigorously evaluated. The result presents optimize power exchange from grid and offers effective power transaction between loads and grid source.
