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.

Why do we need energy storage systems?
