These problems can be prevented by energy storage systems (ESS). Levelling the power demand of an EV charging plaza by an ESS decreases the required connection power of the plaza and smooths variations in the power it draws from the grid.

How much energy does an EV use per station per year?

The total EV charging energy is 22.3 MWh per station per year. The results show that as the PL and the charging plaza size increase, the relative ESS power and energy requirements and the utilization rate of the ESS decrease. This decrease is faster with low PLs and small plaza sizes and slows down with the increasing PL and charging plaza size.
