By comparing these indicators, we can find that the number of public charging piles has the strongest correlation with new energy vehicle ownership, followed by charging capacity and power generation, which are all closely related to the construction of new energy vehicle supporting infrastructure and power supply.
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.
Promoting the adoption of private charging piles will hardly affect the accumulated charging power but will transfer the charging load from public piles to private ones. Due to the different load profiles of the two charging piles, the charging peak will be weakened by day but enhanced at night.
Electric Power System operation of public charging piles. Our survey resu lts show that, for 36% of the office buildings and barrier for the operation of public charging infrastruc ture (Figure 4). In addition, for 40% of the retail failure of the power system. In comparison, the retail buildings were most constrained by the electric power system.
the public charging piles were built up for specific users. T able 3. Regression results: number of two types of public charging piles and EV sales. Notes: coe fficients are reported based on two-way fixed effect panel regression. Cluster-robust standard error at
We find that insufficient public charging piles would significantly limit the sales of electric vehicles, in particular when the public charging piles are built up for specific users or in developed regions where private parking spaces are limited.
