Fast-charging batteries are the non-negligible prerequisite for the worldwide adoption of electric vehicles while pursuing high capacity, long cycle life, high safety, and low cost of the battery.
In practice, one of the efficient ways to mitigate charging congestion and charging cost of fast charging is applying energy storage systems (ESSs) which are generally installed at FCSs (Ding et al., 2015). Any ESS device consists of one battery with a fixed capacity and one ESS charger.

Rechargeable lithium ion battery (LIB) has dominated the energy market from portable electronics to electric vehicles, but the fast-charging remains challenging.

The FCS was composed of a photovoltaic (PV) system, a Li-ion battery energy storage system (BESS), two 48 kW fast charging units for EVs, and a connection to the local grid. With this configuration and thanks to its decentralized control, the FCS was able to work as a stand-alone system most of the time though with occasional grid support.

Battery energy storage can shift charging to times when electricity is cheaper or more abundant, which can help reduce the cost of the energy used for charging EVs. The battery is charged when electricity is most affordable and discharged at peak times when the price is usually higher. The energy consumption is the same in kWh.

A trade-off may arise, as additional lithium-ion battery cells can increase the net system''s fast charging power while keeping the current rate at the cell level constant, but the concurrently increasing high energy storage weight reduces the overall vehicle efficiency, thus reducing the fast charging speed in terms of km/min.
The idea behind using DC-fast charging with a battery energy storage system (BESS) is to supply the EV from both grid and the battery at the same time . This way the demand from the grid is smaller.
