Changsha Evening News handheld Changsha full ** reporter Liu Pan.
Drink a cup of coffee, listen to a song, ......When you finish a small daily task in a few minutes, your car is fully charged and ready to go. Now, the super fast charging technology with a range of more than 300 kilometers after 5 minutes of charging has made this scenario a reality in Changsha.
1-2 seconds can increase by 1-2 kilometers, watching the rapid growth of power, not to mention how comfortable it is. In the past few days, next to the business hall of the pear power supply station, the first "optical storage super charging and inspection" intelligent charging station in the province jointly built by the State Grid Changsha Power Supply Company and the State Grid Hunan Electric Vehicle Company has attracted many citizens to come and experience the super speed of "1 km in 1 second and 600 km in 10 minutes".
The owner praised "charging is comparable to refueling".
On January 9, the reporter saw in the Heshun-Huawei Supercharging Smart Station on Times Sunshine Avenue that in the liquid-cooled supercharging terminal, the owner only needs to open the relevant applet or app of the charging pile, scan *** and follow the steps to make the charging vehicle quickly charged.
Super Fast Charging has a maximum output of up to 600 kilowatts and can be charged at the fastest or '1 km per second', depending on the car model. The on-site staff said that the station integrates optical storage and charging, which can provide a maximum of 600 kilowatts of super charging power for the terminal, adapt to different models, and bring the charging experience of "a cup of coffee and a full charge" to the car owner, greatly shorten the waiting time in line, and bring a convenient energy replenishment experience to the public.
In the pear charging station, several new energy vehicles are also parked that come to charge. "It's so fast, I didn't expect that in just 5 minutes, the new energy vehicle can last nearly 300 kilometers, and the charging speed is comparable to refueling, and it really only takes the time to drink a cup of coffee. On the same day, Xiong Ninghao, who lives in Zhongnan Automobile World, had just gotten off work, and he made a special trip to try to charge his car with super fast charging, and the charging speed gave him a thumbs up.
It is reported that the whole station applies liquid-cooled supercharging, split and integrated fast charging, optical storage, charging and inspection and other technologies, and is equipped with 2 600 kW liquid-cooled super fast charging, 4 180 kW split fast charging, 14 120 kW integrated fast charging, and 2 60 kW DC detection piles, which can provide charging services for 40 electric vehicles at the same time.
Changsha has 1,663 DC fast charging piles.
Charging piles are divided into three categories according to different charging speeds: slow charging, fast charging, and overcharging. Slow charging is mainly in the form of AC charging, while fast charging and overcharging are high-voltage fast charging methods based on DC charging technology, fast charging generally adopts natural cooling and heat dissipation, and the charging power of the terminal is usually less than or equal to 250 kilowatts. Overcharging generally refers to a charging speed that can be as fast as refueling, that is, a charging power of more than 480 kilowatts.
In the face of the rapid growth trend of new energy vehicles, especially electric vehicles, China has clearly proposed that the construction of charging infrastructure should be arranged moderately in advance, and by 2030, a high-quality charging infrastructure system with wide coverage, moderate scale, reasonable structure and perfect functions will be basically built.
At present, the State Grid Hunan Electric Power Company has built more than 1,300 charging stations in the province, more than 7,000 DC fast charging piles, and more than 1,300 orderly AC piles, realizing full coverage at the district and county levels in all cities and prefectures, and cooperating with high-speed groups and other units to achieve full coverage of the highway network in the province.
Changsha has accelerated the development of charging infrastructure, continuously improved the charging network, and has built 253 charging stations, 1,663 DC fast charging piles, and more than 353 orderly AC piles.
High-quality charging infrastructure for smart cities.
Changsha's "14th Five-Year Plan" for the development of electric vehicle charging infrastructure ** By 2025, the number of cars in Changsha will be 397950,000 units, and the number of electric vehicles is 38610,000 units, with an electrification rate of 97%, which is comparable to the planning level of domestic electric vehicle pioneer cities.
The plan clearly states that Changsha will strive to build a charging infrastructure system supplemented by "independent urban fast charging stations, battery swap stations and intercity fast charging stations built in highway service areas" and supported by "charging intelligent service platform", so as to improve the service guarantee capacity of charging and swapping infrastructure and serve the construction of smart cities.
The reporter was informed that in the future, the power sector will also promote the update and iteration of charging technology through technological innovation, manufacturing innovation and consumer application scenario innovation to meet the charging needs of the public. In the future, a more extensive layout of supercharging stations will help new energy vehicle owners replenish energy more efficiently, travel more conveniently, and alleviate "range anxiety" in an all-round way.
