The integration of energy storage systems offers a myriad of benefits to EV charging stations, including: ESS enhance grid resilience by providing backup power during outages and emergencies. This ensures uninterrupted charging services, minimizes downtime, and enhances overall operational reliability.
In order to realize the flexible interaction of the electric energy between the grid and the charging station, the energy storage system is integrated into the charging station to form a charging-discharging/swapping-storage integrated station,,, .
When a large number of EVs are charged simultaneously at an EV charging station, problems may arise from a substantial increase in peak power demand to the grid. The integration of an Energy Storage System (ESS) in the EV charging station can not only reduce the charging time, but also reduces the stress on the grid.

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.
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.
A battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time to provide electricity or other grid services when needed.
