Making charging as fast as refueling, GAC Aion's super-speed battery technology and A480 super charging pile debut globally

On August 30, GAC Aion held an online press conference, officially releasing its super-speed battery technology that can achieve "charging for 5 minutes and driving for 200 kilometers" and the world's highest charging power A480 super charging pile. On the same day, the "World Record Challenge for the Fastest Charging Speed" was live-streamed. The mysterious AION challenge car from the SPEED++ team, equipped with super-speed battery technology, successfully achieved the result of "charging for 5 minutes and driving for 207 kilometers" and obtained the authoritative certification of the World Record Certification Agency (WRCA). Top experts, mainstream media and netizens from all over the country witnessed the birth of the "World Record for the Fastest Charging Speed ​​of Pure Electric Vehicles".

The world's fastest charging speed, 6 times the charging speed of super-speed battery technology

At present, the new energy vehicle market is booming at a high growth rate, but slow and difficult charging are still a major pain point that plagues the development of the industry. In order to solve this pain point, GAC Group's first internally incubated mixed-ownership innovative high-tech enterprise, Juwan Technology Research Co., Ltd., has continued to be committed to the research and development of super-fast charging cells. After 7 years of unremitting efforts, it has successfully developed super-speed battery technology.

"Super-speed" refers to the high battery charging rate. The fastest charging rate of existing electric vehicles can only reach 200km in half an hour, while the super-speed battery technology achieves "5 minutes of charging and 200km of driving" at a charging rate of 6 times the fastest. It takes only the time to charge a cup of coffee and the battery life is enough to travel around the Greater Bay Area. It is currently the fastest charging battery technology in the world.

For a long time, the industry has generally placed the focus of technology on improving charging speed on the charging terminal rather than on power batteries. The main reason is that it is more difficult to make breakthroughs in battery technology than on the charging terminal. According to the working principle of battery charging, lithium ions start from the positive electrode, pass through the diaphragm and electrolyte, and reach the negative electrode, including three processes: extraction, migration, and embedding. The more lithium ions migrate and embed per unit time, the faster the charging speed. However, the low migration speed and low embedding efficiency of lithium ions are the key problems in improving charging efficiency, and have become two technical peaks that are difficult for industry experts to overcome.

In order to solve these two major problems, GAC adopted new technologies and materials such as high-porosity coated ceramic diaphragms, new low-viscosity high-power electrolytes, and unique soft carbon/hard carbon/graphene coating modification technologies. More importantly, in order to find the best formula, a large number of material formulas and process design verifications were carried out over the past 7 years. Ultimately, a comprehensive improvement in migration rate, embedding speed, and conductivity was achieved, greatly accelerating the lithium ion migration process and achieving super-speed charging. Among them, graphene as a conductive agent played a vital role.

As we all know, although graphene is a revolutionary material, it is actually very difficult to master its preparation technology. At present, common graphene preparation methods generally require a strict laboratory environment for support, and can only be extracted on a small scale. As one of the earliest companies in China to conduct commercial research and development of graphene, GAC has mastered the independently developed three-dimensional structured graphene (3DG) preparation technology and has formed a complete patent group. This gives GAC a strong first-mover advantage and extremely high technical reserves in the application of graphene materials and fast-charging batteries. At present, GAC's three-dimensional graphene materials have achieved stable mass production and controllable costs, thereby promoting the mass production of super-speed battery technology.

In addition, in order to ensure the stable operation of fast charging technology, the high-voltage platform has become the "new infrastructure" in the field of fast charging. The development and application of high-voltage platform technology is a major project that affects the entire body. The increase in the voltage platform means that the core three-electric system and a series of components such as the air-conditioning compressor must work normally under high voltage. The Porsche Taycan, the first in the industry to mass-produce an 800V high-voltage platform, has increased its maximum charging power to 350kW, and can charge the power battery from 5% to 80% in 22.5 minutes. GAC Aion has gone a step further and created the industry's most advanced high-voltage platform, with a maximum operating voltage of 880V and a maximum charging power of 480KW, achieving a 5-minute charging time and a range of 200 kilometers. Its technical "gold content" can be imagined.

At present, GAC Aion's super-speed battery technology has passed the mandatory inspection and certification of the National Quality Supervision and Inspection Center, and will be gradually installed in the AION family series of models. It can be foreseen that the successful realization of "charging for 5 minutes and driving for 200 kilometers" super-speed battery technology will greatly promote the development of my country's new energy industry and further accelerate Chinese auto companies to achieve "overtaking in the world".

The A480 supercharging pile with the highest charging power in the world accelerates the deployment of supercharging

As the saying goes, "a good horse deserves a good saddle", the ultimate super-speed battery technology also needs to be matched with the ultimate super-charger. At present, the power of fast charging piles and super-charging piles on the market is generally between 60kW-180kW, and the peak output power of the best-performing Tesla V3 charging pile is only 250KW. It generally takes 15-40 minutes to charge for a range of 200 kilometers. The charging time is long and the experience is poor, and it cannot meet the charging requirements of super-speed batteries. Due to the slow charging speed, it also causes the inefficiency of the public charging network, which has become the biggest obstacle to market development. Taking Guangzhou as an example, 700 gas stations can serve 3 million fuel vehicles, but 2,300 public charging stations serve only 300,000 electric vehicles. In order to allow more users to enjoy the convenience of super-fast charging, the GAC Aion Energy Ecosystem Team has made continuous technological innovation breakthroughs and successfully launched the GAC Aion A480 super-charging pile with the highest charging power in the world through the application of big data of more than 80,000 Aion brand charging piles and more than 200,000 social charging facilities across the country.

"A" is the first letter of AION, and also represents A-level high performance, while "480" represents the world's highest power of 480kW. The super charging pile has four major features: ultra-high power, ultra-high safety, ultra-high intelligence, and ultra-high appearance. It has the world's highest charging power of 480kW, a peak power of up to 1000V, a current of 600A, and adopts a liquid-cooled charging system and AION's exclusive sci-fi water drop design. It can match flexible charging through cloud-based intelligent scheduling, facilitating rapid promotion and popularization.

At this stage, GAC Aion is also accelerating the construction of A480 supercharging piles. The world's first intelligent supercharging station, the GAC Aion Supercharging Station located in Donghong International Plaza, Tianhe District, Guangzhou, has been completed and put into operation. From technology research to technology commercialization, while interpreting GAC Aion's concept of "advancing technological enjoyment", it also means the official start of the GAC Aion Supercharging era.

Next, GAC Aion will also rapidly deploy and build branded supercharging stations across the country, making the charging experience of new energy vehicles equal to that of fuel vehicles, bringing users the ultimate charging experience. It is expected that by 2025, 2,000 supercharging stations will be built in 300 cities across the country, penetrating into prefecture-level cities and achieving full coverage.

Created the world record for the fastest charging speed, opening the door to the era of "making charging as fast as refueling"

During the live broadcast of the "World Record Challenge for the Fastest Charging Speed" held on the day of the press conference, the AION model equipped with super-speed battery technology achieved an impressive result of charging in 5 minutes and driving 207 kilometers under the record and notarization of the world record certification officer, setting a new world record for the fastest charging speed in the history of pure electric vehicles.

The release of GAC Aion's super-speed battery technology and A480 supercharging pile also attracted rave reviews from top industry experts. Cui Dongshu, secretary general of the National Passenger Car Market Information Joint Conference, said: "The launch of GAC Aion's super-speed battery technology and A480 supercharging pile proves that charging pure electric vehicles can be as fast as refueling. In the future, mileage anxiety will no longer be a problem that bothers users, and more consumers will actively choose to embrace new energy vehicles." Zhao Fu, professor of the School of Vehicle and Transportation Engineering at Tsinghua University and dean of the Institute of Automotive Industry and Technology Strategy, said: "Range anxiety and long charging time are still the core issues that plague the development of electric vehicles. The launch of GAC Aion's super-speed battery technology and A480 supercharging pile provides an effective solution to such problems, which is worth looking forward to!"

In November last year, the General Office of the State Council issued the "New Energy Vehicle Industry Development Plan (2021-2035)", pointing out that it is necessary to accelerate the construction of charging and swapping infrastructure, strengthen the research and development of new charging technologies such as intelligent and orderly charging, high-power charging, and plug-and-play charging, and improve charging convenience and product reliability. As the world's only new energy brand with both battery-side and pile-side supercharging technologies, GAC Aion is promoting the industrialization of super-fast charging through self-developed technological innovation in the field of power batteries, bringing users the ultimate charging experience of "charging as fast as refueling".

Looking to the future, GAC Aion is willing to open its arms and explore and share ultra-fast battery technology and A480 supercharging piles with more partners and social forces, achieve in-depth linkage between the upstream and downstream of the industrial chain, promote the accelerated development of China's new energy industry, and jointly create a better green, smart and mobile life, contributing GAC Aion's wisdom and strength to the realization of the grand goal of "carbon peak in 2030 and carbon neutrality in 2060".
