The General Office of the Chongqing Municipal Government recently issued a document, and the city officially launched an action plan for convenient overcharging of new energy vehicles. According to the plan, new public fast charging stations in our central urban areas must have supercharging capabilities, and existing charging stations will gradually be transformed into supercharging stations to form a "1-kilometer supercharging circle." By the end of 2025, the city plans to build more than 2,000 supercharging stations and more than 4,000 supercharging piles.
Specifically, our city will follow the construction principle of "smart, convenient, moderately advanced" to achieve dense distribution of overcharging infrastructure in the central city, and build 1,340 overcharging stations by 2025; the main city new area and Wanzhou District will achieve Overcharging infrastructure is rationally laid out and scenarios are fully covered, with 430 overcharging stations built; northeastern Chongqing and southeastern Chongqing have achieved basic coverage of overcharging infrastructure, with 100 overcharging stations built; highway service areas have been fully covered by overcharging infrastructure. 170 supercharging stations have been built.
In terms of location selection for overcharging stations, our city mainly considers public parking lots, commercial gathering areas, gas stations, rail transit facilities, squares and green spaces, highway service areas, urban corners, bus terminals, In key scenes such as tourist attractions, we will accelerate the construction of overcharging infrastructure. At the same time, comprehensive consideration is given to factors such as the development situation of each district and county, population size, traffic intensity, promotion of supercharged models, station service radius and other factors, and scientific predictions are made based on the layout of gas stations to accelerate the construction of a convenient supercharging ecosystem and better support the deployment of new energy vehicles. Township.
The overcharging station built in our city will support liquid-cooled overcharging with a single gun power of 480 kilowatts and above, and vehicle companies are encouraged to incorporate overcharging and V2G (two-way power transmission between electric vehicles and the grid) into new energy vehicle product functions scope. In principle, integrated charging and storage stations are equipped with energy storage equipment at a scale of no less than 10% of the distribution transformer capacity, a duration of no less than 1 hour, and a capacity of no less than 200 kilowatt hours. The number of integrated charging and storage stations among the newly built supercharging stations in the city The proportion is no less than 30%.
According to the above plan, our city will further promote the construction of the "Electric Corridor" in the Chengdu-Chongqing Economic Circle; accelerate the construction of Chongqing's digital charging platform and guide the city's full access to new energy vehicles and charging and swapping facilities to achieve Jiechong platform "one-click pile search" realizes digital management of new energy vehicles and charging and swapping facilities in the city; supportsThe virtual power plant aggregates charging and swapping facilities to participate in power market transactions, making the city's charging and discharging load "observable, measurable, and controllable"; Chongqing's digital charging platform will be built in 2025; by the end of 2025, a total of V2G demonstrations in the public sector will be built in the central city 45 projects.
