At the south gate of the Olympic Sports Center in Jiulongpo District, Chongqing, a charging station covering an area of about 5,000 square meters is favored by new energy vehicle owners. This comprehensive all-liquid-cooled supercharging station with 16 charging spaces has been in operation for more than two months, with a cumulative charging volume of over 200,000 degrees, and the highest daily average single-gun charging volume reaching 230 degrees.
As the first flagship supercharging station built by Chongqing Yumiaochong Digital Energy Technology Co., Ltd. in a self-built and self-operated mode, the Olympic Sports Jinlong Fully Liquid Cooling Supercharging Station effectively reduces the surrounding charging burden, especially when the Olympic Sports Center holds sports events, cultural performances and other activities. The supercharging station solves the charging problem caused by dense traffic. It is worth noting that the station is an integrated "photovoltaic storage and charging" station, which integrates photovoltaic-energy storage-supercharging-discharging, allowing new energy vehicles to truly use new energy electricity.
This supercharging station is just a representative one. YumiaoChong participated in the construction of supercharging stations in Chongqing. Huawei provided high-quality charging equipment. The two sides jointly accelerated the construction of Chongqing's convenient supercharging city. 30 supercharging stations have been put into operation in Chongqing, penetrating into core business districts, logistics parks, transportation hubs, parks, scenic spots, old communities and other scenes. The average daily charging volume of these supercharging stations increased by 60% in 3 months, and the cumulative charging volume reached 5 million degrees. If 1,000 stations are invested and built, based on the average daily charging of 200 degrees per gun, the annual revenue potential will reach 700 million yuan.

The explosion of new energy vehicles calls for "supercharging"
Not long ago, the logo of Chongqing Jiechong "Building a Convenient City, Constructing a Supercharging Ecosystem" appeared on the electronic screens of core landmarks such as Chongqing Jiefangbei Pedestrian Street. Chongqing citizens truly felt the arrival of the "Convenient Supercharging City".
"Chongqing JieChong" is the city-wide unified public supercharging brand launched by Chongqing City. Behind this is Chongqing City's overall planning and continuous efforts in the construction of new energy vehicle charging facilities.
Charging piles are divided into three types: slow charging, fast charging, and super charging according to the difference in charging efficiency. Slow charging is mainly charged in the form of AC, while fast charging and super charging are high-voltage fast charging methods based on DC charging technology. The charging speed of super charging is about 10 times that of ordinary charging piles. Taking the full liquid-cooled host of Huawei Super Charging used in the Olympic Sports Jinlong Full Liquid Cooling Super Charging Station as an example, the maximum power reaches 720 kilowatts, the maximum power of the super charging terminal is 600 kilowatts, the fastest charging speed is close to "one kilometer per second", and the battery life is 200 kilometers after charging for 5 minutes, and it is widely compatible with various types of vehicles. Not only is the charging speed fast, but from the perspective of the charging station, Huawei's full liquid-cooled super charging is very quiet when used, and the equipment service life exceeds 15 years.
It is precisely because of the word "fast" that supercharging is favored by car owners and has become a hot spot for competition in the global new energy vehicle industry. Many domestic and foreign car companies and battery suppliers have increased their investment in the field of supercharging.
At the Chongqing Convenient Supercharging City Construction Summit held recently, Chongqing Vice Mayor Jiang Duntao said that Chongqing is adapting to the rapid development trend of the intelligent networked new energy vehicle industry, seizing the window period, strengthening top-level design, organizing systematic planning, and promoting the construction of a convenient supercharging city. He pointed out that this is not only an inherent requirement for promoting high-quality development and creating a high-quality life, but also a practical need to seize the initiative and voice in the new round of industrial transformation.
How to understand the “window period”?
By the end of 2023, China's new energy vehicle ownership will reach 20.41 million. In 2023, China's new energy vehicle production and sales will reach 9.587 million and 9.495 million, respectively, up 35.8% and 37.9% year-on-year. The latest data shows that in July 2024, conventional fuel passenger cars will be sold at a retail price of 840,000 units, and new energy passenger cars will be sold at a retail price of 878,000 units. The domestic retail penetration rate of new energy passenger cars will reach 51.1%, and the monthly domestic retail sales of new energy passenger cars will exceed those of traditional fuel passenger cars for the first time.
At the same time, charging is the main concern of consumers when purchasing new energy vehicles, and it has also become a key issue that constrains the entire industry. With the increasing number of new energy vehicles, the demand for charging facilities is becoming more and more urgent.
In June this year, the National Development and Reform Commission held a press conference to announce that since the General Office of the State Council issued the "Guiding Opinions on Further Building a High-Quality Charging Infrastructure System", the National Development and Reform Commission has actively promoted the rapid development of charging infrastructure and achieved remarkable results. my country has built the world's largest charging infrastructure system with the widest service scope and the most complete types of products.
Just last week, the CPC Central Committee and the State Council issued the "Opinions on Accelerating the Comprehensive Green Transformation of Economic and Social Development", which carried out top-level design and systematic planning for accelerating the comprehensive green transformation of economic and social development. While clarifying "vigorously promote new energy vehicles and promote the electrification of urban public service vehicles", the "Opinions" also deployed the construction of green transportation infrastructure and "improved the infrastructure network such as charging (replacement) stations, hydrogen (alcohol) stations, and shore power".
New energy vehicles and their charging facilities have gone beyond the scope of transportation and are gradually becoming an organic part of the new power system. Chongqing Olympic Sports Jinlong Fully Liquid-Cooled Supercharging Station uses Huawei Supercharging and Huawei's "Photovoltaic Storage and Charging" integrated solutions in terms of technology. The 407 square meters of photovoltaic panels in the station can not only generate electricity efficiently, but also have the function of shading and sheltering from rain. Even in Chongqing, where sunshine conditions are relatively limited, the average daily photovoltaic power generation has reached 400 degrees. According to staff, the energy storage capacity of the charging station is 215 kWh, and the stored electricity comes from both photovoltaics and the power grid. During the low-power consumption period at night, the charging station will "store" the electricity at a lower low-peak electricity price, and then "release" the electricity during peak hours. The calculated peak-shifting energy storage charging solution makes the charging and discharging efficiency higher and the electricity cost lower.
Layout of "super charging":
Chongqing's choice to return to being the "first city for automobiles"
Charging stations are not only infrastructure that serves and protects people’s livelihood, but also an important support for promoting new energy vehicle consumption and industrial development.
"The construction of a charging infrastructure system with supercharging as the main focus is not only related to consumers' willingness to purchase new energy vehicles, the sales and popularization of new energy vehicles, but also to the high-quality development of Chongqing's trillion-level intelligent connected new energy vehicle industry." Wang Zhijie, director of the Chongqing Municipal Economic and Information Commission, said that Chongqing is building a first-class convenient supercharging city in the country from the height of the industrial ecology, from hardware facilities such as charging stations and piles, to technology, networks and other services.
As of the end of July this year, Chongqing has built more than 320,000 charging piles, including 36,000 public charging piles and 286,000 personal charging piles. The average car-to-pile ratio is about 21, which is better than the national average of 2.41.
In the time it takes to drink a cup of coffee, a new energy vehicle can be fully charged. Chongqing has focused on building a "supercharging city" by developing supercharging stations. So far, Chongqing has built or is building about 500 supercharging stations and about 800 supercharging piles, both of which are among the largest in the country.
In March 2024, Chongqing took the lead in releasing the "Chongqing New Energy Vehicle Convenient Supercharging Action Plan (2024-2025)", and issued the "Chongqing Supercharging Infrastructure Construction Technical Guidelines". According to the plan, Chongqing will build 2,000 supercharging stations and 4,000 supercharging piles in 2025. By then, all new public fast-charging stations in the central urban area of Chongqing will have supercharging capabilities, and existing charging stations will be gradually transformed into supercharging stations, forming a "one-kilometer supercharging circle".
Chongqing has a profound industrial foundation and forward-looking layout and is making every effort to promote the construction of a city of convenient supercharging.
As the city that produced China's first jeep in 1958, Chongqing has the largest automobile industry cluster in China. In 2022, the Chongqing Municipal Government issued the "Chongqing World-Class Intelligent Networked New Energy Vehicle Industry Cluster Development Plan (2022-2030)", which proposed that by 2025, Chongqing's intelligent networked new energy vehicle production and sales will account for more than 10% of the national total; by 2030, a world-class intelligent networked new energy vehicle industry cluster will be built, and the industry scale will reach the world's first-class level.
In 2023, Chongqing began to build a "33618" modern manufacturing cluster system, with intelligent networked new energy vehicles ranking first among the three trillion-yuan industrial clusters. In the same year, Chongqing's automobile production exceeded 2.3 million vehicles, ranking second in the country, of which the production of intelligent networked new energy vehicles exceeded 500,000 vehicles.
This historic automobile city is using "new energy" as an engine to achieve "overtaking in a new lane" in the automobile industry. In the first half of this year, the output of "Made in Chongqing" vehicles reached 1.214 million units, returning to the top of cities in China. Among them, the output of intelligent networked new energy vehicles reached 391,000 units, a year-on-year increase of 1.5 times, leading the country in growth rate.
The performance of local auto brands in the field of new energy vehicles has also given Chongqing enough confidence. From January to June, Changan Automobile's self-owned brand new energy vehicles sold 299,000 units, a year-on-year increase of more than 69%; Seres' new energy vehicles sold more than 200,000 units, a year-on-year increase of about 348%.
Wang Zhijie said that competition in the new energy vehicle industry is shifting from disorderly involution to high-quality, sustainable and healthy development led by technological innovation. This is inseparable from the focus of ecosystem companies on breakthroughs in key core technologies. Convenient supercharging construction and supercharging vehicle research and development must go hand in hand to provide a high-quality charging experience.
It is reported that Chongqing is also promoting the digital management of supercharging stations across the city, and accelerating the introduction and cultivation of a number of leading enterprises with core competitiveness and influence to cultivate a complete charging industry chain.
You chase me:
“Supercharging Cities” are emerging across the country
Industry insiders believe that Chongqing has built a convenient, intelligent and efficient new energy vehicle charging service system, which provides a "roadmap" for cities across the country to learn from. Only when local governments unify planning and standards and build charging infrastructure can electricity-friendly, intensive and orderly charging be achieved, and the level of urban management safety be improved.
Hou Jinlong, Huawei director and president of Huawei Digital Energy, said that Chongqing has provided new ideas and models for the development of high-quality charging infrastructure. Through unified planning, unified standards, unified platforms, and unified logos, the city has rationally laid out convenient supercharging and fast charging, creating a new business card for Chongqing's new energy vehicle industry. "I hope that more cities will become 'supercharging cities' in the future, so that wherever there are roads, there will be high-quality charging, allowing more electric vehicles to travel without worries," he said.
Wang Fan, general manager of Chongqing Yumiao Chong Digital Energy Technology Co., Ltd., said that with the help of Huawei Supercharging and Huawei's "photovoltaic storage and charging" integrated solution, "Yumiao Chong" will further promote full liquid cooling supercharging technology in the future and accelerate its national layout.
Liu Dawei, President of Huawei Digital Energy Smart Charging Network Global Business, said that the products and solutions provided by Huawei, through ultra-fast integration, bipolar power pooling, integrated photovoltaic storage and charging and other innovative technologies, allow the power grid to "be assured of distribution". By "building an ecosystem together", users can "buy with confidence", operators can "build with confidence", and car companies can "build good cars with confidence", making urban governance "more efficient" and "safer".
Li Ying, deputy general manager of the New Energy Business Department of Luzhou Energy Investment Co., Ltd., introduced that Luzhou Energy Investment and Huawei have jointly planned a "one, ten, hundred, thousand" demonstration project, where "hundred" refers to the layout of 100 public supercharging stations in Luzhou city within 2 to 3 years, and "thousand" refers to the layout of about 1,000 rural charging points in the city by 2030. Ge Weiliang, manager of the New Energy Business Department of the New Infrastructure Group of Fuzhou Urban Investment, said that Fuzhou Urban Investment will continue to work with Huawei to help build the Fuzhou supercharging infrastructure ecosystem.
He Hao, president of SERES' automotive platform technology system, said that in January this year, SERES and Huawei Digital Energy signed a comprehensive strategic cooperation agreement to jointly build a "supercharging network". It is reported that Huawei Digital Energy, together with the first batch of 11 automakers, industry associations, and charging operators such as BYD, GAC, and BAIC, established the Supercharging Alliance at the 2024 Beijing International Auto Show. Huawei is working with automakers, power grids, operators, etc. to build a high-quality smart charging network around typical scenarios such as cities, highways, counties, logistics heavy trucks, and public transportation, helping to create more "supercharging cities".
"A cup of coffee, a full charge", "a bowl of noodles, a full charge", "a bowl of rice noodles, a full charge"... Spend less time and charge more electricity. Supercharging allows car owners to say goodbye to charging anxiety. Nowadays, new energy vehicles have achieved convenient and fast charging in more and more cities. "Plug and charge, charge and go" has turned from a dream into reality.
