In recent years, the world has been committed to low-carbon development, and the development of new energy vehicles has accelerated worldwide, and its production and sales have also increased year by year. At the same time, as an indispensable supporting facility for new energy vehicles, the charging pile industry is also ushering in vigorous development.
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.
