The total rated power of public charging piles exceeds 110 million kilowatts, meeting the charging needs of 24 million new energy vehicles, it said. In the first half of the year, the nationwide charging volume for new energy vehicles was around 51.3 billion kilowatt-hours, a year-on-year increase of 40 percent.
In this paper, the battery energy storage technology is applied to the traditional EV (electric vehicle) charging piles to build a new EV charging pile with integrated charging, discharging, and storage; Multisim software is used to build an EV charging model in order to simulate the charge control guidance module.
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.
Compared with the existing mainstream fast charging pile, each supercharging pile can increase the charging efficiency by 350 percent. Flourishing green development Chinese automaker GAC Aion has planned to build 220 charging stations in Guangzhou within 2022 and increase the number to 1,000 by 2025, according to a GAC Aion official.
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.
