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. Once the charging is complete and the EV is disconnected, however, the battery is charged even in the absence of an EV. Therefore, the same amount of energy is

Although the majority of energy requirements for these operations could come from "off-shift" charging, fast and ultra-fast charging will be needed to extend range such that operations currently covered by diesel can be performed by battery electric trucks with little to no additional dwell time (i.e. waiting). Regulations that mandate rest periods can also provide a time window

To optimize grid operations, concerning energy storage charging piles connected to the grid, the charging load of energy storage is shifted to nighttime to fill in the valley of the grid's baseline load. During peak electricity consumption periods, priority is given to using stored energy for electric vehicle charging.
Combining Figs. 10 and 11, it can be observed that, based on the cooperative effect of energy storage, in order to further reduce the discharge load of charging piles during peak hours, the optimized scheduling scheme transfers most of the controllable discharge load to the early morning period, thereby further reducing users' charging costs.
