AI Customer ServiceElectric vehicles (EVs) and charging piles have been growing rapidly in China in the last five years. Private charging piles are widely adopted in major cities and have partly
AI Customer ServiceThe 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.
With the continual progress of charging technology, the overall charging power of public charging piles has steadily increased. In the past three years, the average power of public DC charging piles has exceeded 100 kW to meet the requirements of long range and short charging duration of electric vehicles.
First, providing more public charging piles is important to increase the sales of electric vehicles. In addition, the residential, office, retail, and government communities have different advantages and obstacles. It is more feasible to install the public charging piles in the residential and the government communities.
The findings in this paper provide important implications for EV industry development in China. First, providing more public charging piles is important to increase the sales of electric vehicles. In addition, the residential, office, retail, and government communities have different advantages and obstacles.
In addition, for 40% of the retail buildings, there was another barrier: operating the public charging piles may cause the operation failure of the power system. Figure 4. Electric power system. In comparison, the retail buildings were most constrained by the electric power system.
