Huawei Digital Energy builds a smart charging network to achieve coordinated development of vehicles, piles and networks

my country’s new energy vehicle market has ushered in explosive growth driven by the “double carbon” goal in recent years. According to data, from 2012 to 2022, the average annual compound growth rate of new energy vehicle sales in my country reached 87.2%. In 2022, domestic sales of new energy vehicles will reach 6.887 million units, a year-on-year increase of 93.4%, which is particularly significant.

However, with the rapid expansion of the new energy vehicle market, the supply of charging infrastructure can no longer meet development needs. The main factors limiting the promotion and market expansion of new energy vehicles include slow charging speeds and high equipment failure rates.

Against this background, Huawei Digital Energy began to think about how to apply digital technology and power electronics technology to the charging field to contribute to the new energy automobile industry.

According to the editor’s understanding, Huawei Digital Energy recently released a new generation of fully liquid-cooled supercharging architecture in Shanghai, aiming to create a high-quality, sustainable charging infrastructure. This architecture integrates optical storage technology, introduces digital technology and power electronics technology to the charging industry, provides more advanced productivity, provides users with a more comfortable charging experience, and at the same time creates greater value for the industry and industry.

The editor visited the fully liquid-cooled supercharging station in Wukesong, Beijing. Although the equipment is still in debugging state, we can get some key information from the site.

The charging station is equipped with Huawei’s latest 600kW fully liquid-cooled supercharging host and a supercharging terminal that supports up to 600kW charging power. It is also equipped with a charging terminal that supports up to 250kW fast charging power. Compared with other brands, Huawei's power distribution cabinets and charging piles are smaller. According to Huawei official and previous media tests, the noise of this charging station is lower than that of super charging stations in other industries.

The liquid-cooled charging gun cable is lighter than the traditional naturally cooled cable and can even be operated with one hand, which is very friendly to female users.

It is understood that the charging efficiency of Huawei’s fully liquid-cooled supercharging architecture can charge more than 200 kilometers in 5 minutes. The charging time is roughly calculated to be close to 1 second and 1 kilometer.

Users can now use Huawei's fully liquid-cooled supercharging stations for charging through the State Grid Charging App because they have cooperated with the State Grid. Although the number of sites currently using Huawei's fully liquid-cooled supercharging architecture is relatively small, we expect that more cities and sites will adopt this architecture in the future.

He Bo, President of Huawei's Digital Energy Critical Power Supply and Charging Network Product Line, said that Huawei's new generation fully liquid-cooled supercharging architecture has three major characteristics: "one architecture", "two synergies" and "three extremes" .

The so-called "one architecture" means that long-term returns can be obtained through a single investment. Compared with traditional solutions, charging efficiency is increased by 30% and overall costs are reduced by 40%. Huawei's fully liquid-cooled supercharging architecture can build an integrated urban charging network in the future, while interacting with optical storage and power grids. It not only provides charging services, but can also be used in virtual grids, smart grids and other fields during leisure time, providing partners and users with Bring more business models and return on investment.

"Two synergies" refers to the integration and development of electric vehicles, charging stations and networks, to achieve full intelligence of charging networks.. The fully liquid-cooled supercharging architecture realizes two modes of pile-network collaboration and vehicle-pile collaboration.

The "three extremes" refer to the ultimate experience, extremely high quality and excellent returns. The ultimate experience includes a one-time charging success rate of more than 99%, plug-and-charge convenience, a fast charging experience that can last 200 kilometers in 5 minutes, and a low-noise charging experience of less than 60dB. The ultra-long life of the equipment is ensured by a fully liquid-cooled supercharged architecture that conducts extensive data simulation, innovative design and rigorous testing and verification to ensure an extremely high level of quality. By adopting measures such as power sharing and self-developed technology optimization, utility power utilization and system efficiency can be improved, thereby achieving excellent benefits while reducing operating costs.

Huawei Digital Energy adheres to the concept of future-oriented and continuous evolution when developing charging products. Their goal is to provide users with a "plug and charge, charge and go" charging experience and meet the needs of "good, fast and comfortable" charging processes. He Bo said that Huawei has made a breakthrough in high-power liquid cooling technology this time and achieved the ultimate experience, extremely high quality and excellent profits. This is the implementation of their original research and development concept.

The maximum power of a single cabinet can reach 720kW, which benefits from Huawei's leading design - fully liquid-cooled supercharged architecture. Regarding why two higher-power supercharging terminals were selected for launch from the beginning, the person in charge of Huawei's digital energy said that this was based on considerations of market demand and user experience. Their goal is to bring more convenient charging services to users by launching products with high power transmission, high energy efficiency and good user experience, thereby promoting the development of the new energy vehicle market.

Currently, Huawei Digital Energy is accelerating the commercialization of the fully liquid-cooled supercharging architecture, striving to provide users with a better charging experience and help the new energy automobile industry continue to develop healthily.
