The energy storage charging pile achieved energy storage benefits through charging during off-peak periods and discharging during peak periods, with benefits ranging from 699.94 to 2284.23 yuan (see Table 6), which verifies the effectiveness of the method described in this paper.
Based Eq. , to reduce the charging cost for users and charging piles, an effective charging and discharging load scheduling strategy is implemented by setting the charging and discharging power range for energy storage charging piles during different time periods based on peak and off-peak electricity prices in a certain region.
The proposed method reduces the peak-to-valley ratio of typical loads by 52.8 % compared to the original algorithm, effectively allocates charging piles to store electric power resources during off-peak periods, reduces user charging costs by 16.83 %–26.3 %, and increases Charging pile revenue.
The rapid development of electrochemical energy storage (EES) devices requires multi-functional materials. Nickel (Ni)-based materials are regarded as promising candidates for EES devices owing to their unique performance characteristics, low cost, abundance, and environmental friendliness.
As the nickel content increases, the charge-discharge capacity also increases, but it can make the cathode material more sensitive to external factors such as temperature and humidity, which is not conducive to the stability of the inherent structure during repetitive charge-discharge cycles , .
In the charging and discharging process of the charging piles in the community, due to the inability to precisely control the charging time periods for users and charging piles, this paper divides a day into 48 time slots, with the control system utilizing a minimum charging and discharging control time of 30 min.
