| Abstract |
In this research work, a modeling and control technique for a two-stage DC charger module is described with relevant dynamic equations and transfer functions. The simulation study and real-time testing of charging (G2V) and discharging (V2G) operation for a medium-duty electric vehicle with Combo CCS type 2 connector port is also performed. It is investigated that the power transfer efficiency for V2G operation using the Combo CCS Type 2 connector reaches approximately 94\% for 4.8kW and 83\% for 3kW. It is also found that higher power charging and V2G operations shows lower Total Harmonic Distortion (THD). For instance, during a power transfer of 5.1kW back to the grid at 60\% State of Charge (SoC), the current THD is observed to be 3.12\%. In contrast, the THD during charging mode is measured at 2.42\%. These results highlight the improved quality of power during high-power charging and V2G operations, indicating reduced harmonic content and enhanced grid stability. |
