The presented model of the charging system is considered for ultra-fast direct current (DC) charging of many electric vehicles. Components suitable for working at high voltages and currents are required and to be characterized by considerable dimensions. The location of these charging systems is outside the vehicle that is off-board. These systems are advantageous in the sense that the charging time is reduced and vehicle space is reduced which gives a margin to use more powerful batteries. A charging station design and modeling for fast DC recharging suitable for number of EVs is discussed. The station has a grid side inverter via DC bus with EVs connected.The charging station model was also designed to support vehicle-to-grid (V2G) and reactive power compensation. Each component is modeled and its parameters are tabulated.In addition, a control system is also included. MATLAB/Simulink SimPowerSystems tool is used to model and simulated the system. State of charge, current and voltage of battery and DC bus voltage is monitored throughout the simulation to prove the effectiveness of proposed model and a smooth change to V2G mode is observed and compensation reactive power is also feasible.
