At the 2023 International Digital Energy Exhibition held on the 29th, Shenzhen launched its first fully liquid cooled overcharging demonstration station and announced the launch of the "Supercharging City" construction. Within three years, 300 new energy vehicle overcharging stations will be built, achieving a 1:1 ratio between overcharging stations and gas stations. By 2030, charging will be more convenient than refueling. When the car enters the charging station, the owner starts charging and goes to the nearby coffee shop to order a cup of coffee. After comfortably drinking the coffee, they can drive into a fully charged car and set off. The first fully liquid cooled and overcharged demonstration station in Shenzhen provides a new experience for new energy vehicle travel. Shenzhen Power Supply Bureau of China Southern Power Grid is one of the joint construction parties for the full liquid cooling and overcharging demonstration station. Feng Yuebo, General Manager of the Emerging Industries Department of the bureau, said that the so-called "overcharging" refers to charging devices that are faster than fast charging, with a maximum output power of 600 kilowatts, a maximum output current of 600 amperes, and the fastest charging speed of "one second per kilometer". The charging equipment of the full liquid cooling overcharging demonstration station adopts the latest full liquid cooling technology, effectively solving the problem of temperature rise during long-term high-power charging, and providing a quieter, more stable, and safer charging environment. "The on-site technical expert of Huawei Technology Co., Ltd., the technology provider of the full liquid cooling overcharging demonstration station, said that the first solution for full liquid cooling overcharging is fast charging speed; The second is good heat dissipation. Compared to traditional air cooling technology, fully liquid cooled overcharging technology has fewer vulnerable parts and higher reliability, which can increase the equipment's lifespan to 20 years; The third is quietness. Due to the lack of a large number of fans for heat dissipation, the noise during charging is very low. With the continuous development of the new energy vehicle industry, the number of new energy vehicles in China is constantly increasing. According to data from the Ministry of Public Security, as of the end of 2022, the total number of new energy vehicles in China has reached 13.1 million. Building a higher-level, faster, and denser charging network has become a 'must-have'. Shenzhen has a solid foundation for building a "super charged city". Qin Weizhong, mayor of Shenzhen, who attended the event, said that as of the first half of this year, the number of new energy vehicles in Shenzhen had reached 860000, ranking first among Global city. At the same time, there are 24000 new energy and digital energy enterprises, and technologies such as photovoltaic and lithium-ion energy storage are at the forefront of the world. According to the Special Plan for Charging Facilities of New Energy Vehicles in Shenzhen, the scale of new energy vehicles in the city will reach 1.3 million by the end of 2025. The construction of matching charging infrastructure has also become a natural choice. According to the plan, by 2025, Shenzhen will build 300 overcharging stations, with a 1:1 ratio of overcharging stations to gas stations, and initially build a "city of overcharging". At the same time, based on the distribution of the movement trajectory of new energy vehicles, we will focus on building a supply and demand matching, moderately advanced, and technologically advanced overcharging network around airports, high-speed rail hubs, municipal parks, core commercial supermarkets, and high-speed service areas. The construction of a large number of overcharging stations will also put forward higher requirements for power grid construction. Feng Yuebo said that Shenzhen Power Supply Bureau will provide citizens with more convenient and fast charging services and support the network construction of Shenzhen's "overcharge city" through technology and platform construction such as "charging, storing and releasing a network" and "Virtual power plant management platform".
