Common Problems with Electric Vehicle Charging Pile. [1] Power Selection. The power of the AC charging pile should not be less than the power of the on-board charger (OBC). But the question that is often encountered is whether it is necessary to choose a higher power such as 22KW?
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.
The stage of solar energy storage has five cycles, and each cycle consists of an eight-hour charging phase and a sixteen-hour recovery phase. This is based on the consideration that the solar radiation in practice is intermittent. It is recognised that in practice the intensity of solar radiation varies with time during the day, while a constant intensity of radiation was
