This work reviews the existing electric vehicle (EV) charging systems to identify the need for Extreme Fast Charging (XFC). EV XFC scheme, which employs Partial Power Processing (PPP), is discussed, and the advantages of a Partial Power Charging Unit (PPCU) over a Full Power Charging Unit (FPCU) are examined with the help of simulations. The possibility of using the PPP scheme to charge a 400 V battery configuration, which can temporarily be converted to 800 V for fast charging, is also discussed. MATLAB Simulink is used to carry out simulations to demonstrate the operation of the converter circuits constituting the XFC and to aid in comparing the FPCU and PPCU. The simulation results indicate that the DC-to-DC conversion stage has processed a significantly small fraction of the total power delivered to the EV battery. An important observation that follows is that the power semiconductor components required for the DC to DC-conversion stage of a partial power charger unit have lower ratings than the components needed for a complete power charger unit.
