DC charging piles have a higher charging voltage and shorter charging time than AC charging piles. DC charging piles can also largely solve the problem of EVs'' long charging times, which is a key barrier to EV adoption and something to which consumers pay considerable attention (Hidrue et al., 2011; Ma et al., 2019a ).

In this calculation, the energy storage system should have a capacity between 500 kWh to 2.5 MWh and a peak power capability up to 2 MW. Having defined the critical components of the charging station—the sources, the loads, the energy buffer—an analysis must be done for the four power conversion systems that create the energy paths in the station.
However, the high cost of energy storage is a difficult problem for the integrated development of "light storage and charging". At present, some PV+ electric vehicle battery charging projects are implemented, and the energy storage unit is postponed. The fundamental reason is that the energy storage cost is too high.
