In June 2023, the General Office of the State Council issued the "Guiding Opinions on Further Building a High-quality Charging Infrastructure System", which clearly stated that the construction of charging infrastructure should be arranged in advance. Recently, supercharging stations in many places across the country have been put into operation, and new energy vehicle owners can be fully charged in the time they can drink a cup of coffee. The development of comprehensive ultra-fast charging presses the accelerator button.
National Highway 318 is known as the golden route for self-driving travel. Due to the high altitude and large temperature difference, the plateau power supply of electric vehicles has become a major problem. After the Kangnan Tourism Distribution Center in Ganzi Prefecture, Sichuan Province has adopted the charging pile of "full liquid-cooled supercharging" technology into operation, the charging problem has been solved, and the maximum output power of the supercharging pile here can reach 600kW, and the fastest charging speed is close to "1 km in 1 second", so that new energy vehicle owners can also drive the Sichuan-Tibet line.
"Full liquid-cooled supercharging" refers to the technology in which the heat dissipation system is liquid-cooled, and the heat generated by the device is carried away by the liquid circulation in the liquid-cooled module to achieve fast and efficient heat dissipation of the device, so as to achieve ultra-fast charging with high power. And such a fully liquid-cooled supercharging pile has also been put into use in Guangzhou recently. The first intelligent supercharging station in the Greater Bay Area, with an overall area of about 9,000 square meters, can meet the charging needs of 68 electric vehicles at the same time, and can last 300 kilometers in as little as 5 minutes.
Guangzhou new energy vehicle owners: The general fast charging pile takes about 40 minutes to more than an hour to be fully charged, and the overcharge can be about 50% in about 10 minutes.
The fully liquid-cooled supercharging pile makes the charging of electric vehicles have a refueling experience, from the past "charging for one hour and queuing for four hours" to now "a cup of coffee, full charge". It is understood that Shenzhen will build a "supercharging city", Guangzhou will build a "supercharging capital", and Hainan will aim at "supercharging island". In addition, Shandong, Zhejiang, Hefei and other provinces and cities have successively introduced policies to accelerate the construction of high-quality charging infrastructure.
Wang Du, Assistant to the President of China Automobile Dealers Association: We believe that 2023 should be the first year of overcharging. The construction of charging piles for leading enterprises is in full swing, and scale advantages have been formed. The next 5 to 7 years will enter a period of rapid development and even explosion of supercharging.
