The world’s premiere of GAC Ion’s super-speed battery technology and A480 super-charged pile in 5 minutes

China Quality News Network (Yu Chang) GAC Ion has realized supercharged battery technology with the blessing of 3DG graphene materials. On August 30th, GAC E’an held an online press conference and officially released the super-speed battery technology that can achieve “5 minutes of charging and 200 kilometers of battery life” and the world‘s highest charging power A480 supercharger.

On the same day, there was also a live broadcast of the “World Record Challenge for the World‘s Fastest Charging Speed”. From the SPEED++ team, the AION mysterious challenge car equipped with super-speed battery technology successfully achieved the result of “charging for 5 minutes and driving 207 kilometers” and was certified by the World Records Certification Agency (WRCA). The official release of the overcharge station undoubtedly proves that GAC Aeon’s battery technology has the ability to be applied on the ground.

Qiu Liangping, Director of Brand Communication Department of GAC Aon, said: “The new energy vehicle industry will enter a new era represented by the sustainable use of energy ecology, the future smart travel ecology, and the business model innovation ecology. GAC Aon will continue to The construction of the “three major ecology” contributes wisdom and strength. Among them, the “optical storage and replacement” is the key to accelerating the construction of a sustainable energy ecology. The release of the “super speed battery technology & A480 super charging pile” is one of the most important The first link. The arrival of super-speed battery technology and the A480 supercharger marks that GAC Aeon is once again at the forefront of the world in the field of automotive electrification technology, opening the technological era of’charging as fast as refueling’.”

The world‘s fastest charging speed, super-speed battery technology with 6 times the charging rate

At present, the new energy vehicle market is booming at a high growth rate. However, slow charging and difficulty in charging are still a major pain point that plagues the development of the industry. To this end, GAC Group’s first internally incubated mixed-ownership innovative high-tech company, Juwan Technology Co., Ltd., has continued to devote itself to the research and development of super fast charging cores. After 7 years of unremitting efforts, it has successfully developed super fast battery technology.

“Super speed” refers to the high charging rate of the battery. Existing electric vehicles can only charge up to 200km in half an hour. The super-speed battery technology achieves “charge for 5 minutes and 200 kilometers” at the fastest charging rate of 6 times. The charging time of a cup of coffee is enough. Traveling throughout the Greater Bay Area is currently the world’s fastest charging battery technology.

For a long time, the industry has generally focused on the pile end rather than the power battery for the technology to increase the charging rate. The main reason is that it is more difficult to make a breakthrough in battery technology than the pile end. 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 of extraction, migration and embedding. The more lithium ions migrate and intercalate per unit time, the faster the charging speed. The low migration speed of lithium ions and low embedding efficiency, as the key problems in improving charging efficiency, have become two major technical peaks that industry experts are difficult to overcome.

In order to solve these two problems, GAC has 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; It is important that in order to find the best formula, a large number of material formulas and process design verifications have been carried out within 7 years, and finally achieved a comprehensive improvement in the migration rate, embedding speed and conductivity, which greatly accelerates the lithium ion migration process, thereby Achieve super-speed charging. Among them, graphene as a conductive agent plays a vital role.

As we all know, although graphene is a revolutionary material, it is actually very difficult to master its preparation technology. The current common preparation methods of graphene generally require a strict laboratory environment to support, and can only be extracted on a small scale. As one of the earliest companies in China to conduct commercialized research and development of graphene, GAC has mastered the independently developed three-dimensional graphene (3DG) preparation technology and formed a complete patent group. This allows GAC to have a strong first-mover advantage and extremely high technical reserves in the application of graphene materials and fast-charge batteries. According to GAC Group news, GAC 3D graphene materials have achieved stable mass production and controllable costs, which has helped to promote the mass production of super-speed battery technology.

In addition, in order to allow fast charging technology to operate stably, high-voltage platforms have become the “new infrastructure” in the fast charging field. The development and application of high-voltage platform technology is a large-scale project that “will affect the whole body”. The rise of the voltage platform means that a series of components such as the core three-electric system and the air-conditioning compressor must work normally under high voltage. The high-voltage platform built by GAC Aeon has a maximum working voltage of 880V and a maximum charging power of 480KW. It can be charged for 5 minutes and has a battery life of 200 kilometers.

At present, GAC Aion’s super-speed battery technology has passed the mandatory inspection and certification of the National Quality Supervision and Testing Center, and will be successively installed in the AION family of models. It is foreseeable that the successful realization of the super-speed battery technology of “5 minutes of charging and 200 kilometers of battery life” will greatly promote the development of my country’s new energy industry and further accelerate the realization of “changing lanes and overtaking” by Chinese car companies worldwide.

A480 supercharger with the highest charging power in the world, speeding up the supercharge layout

As the saying goes, “a good horse is equipped with a good saddle”, the super-speed battery technology also needs to match the super-charged pile. At present, the power of fast charging piles and super charging piles on the market are generally between 60kW-180kW, and the battery life of 200 kilometers generally needs to be charged for 15-40 minutes. The charging time is longer, the experience is poor, and it cannot meet the charging requirements of super-speed batteries. Due to the slow charging speed, it also caused the inefficiency of the public charging network, which became the biggest obstacle to the development of the market. Taking Guangzhou as an example, 700 gas stations can serve 3 million fuel vehicles, but the 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, GAC Aian Energy Ecological Team has made continuous breakthroughs in technological innovation, and has adopted more than 80,000 Aian brand charging piles across the country and over 200,000 social charging facilities big data applications. Successfully launched the GAC A480 supercharger with the highest charging power in the world.

“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 characteristics: super high power, super safety, super intelligence, and super appearance. It has the world‘s highest charging power of 480kW, peak power up to 1000V, current 600A, and liquid-cooled charging The system and AION’s exclusive sci-fi water drop shape design can match flexible charging through cloud intelligent scheduling, which is convenient for rapid promotion and popularization.

At this stage, GAC E’an is also accelerating the construction of A480 supercharged piles. The world‘s first intelligent overcharging station-GAC Ai’an overcharging station located in Donghong International Plaza, Tianhe District, Guangzhou, has been completed and put into operation. From technical research to technical commercial application, while interpreting the concept of “Ahead of Technology Enjoyment” of GAC Ion, it also means that the era of GAC Ion’s supercharge is officially opened.

Next, GAC Aeon will also rapidly deploy and build branded overcharging stations nationwide, equating the charging experience of new energy vehicles with the refueling of petrol vehicles, and bringing usersgoodCharging experience. It is estimated that by 2025, 2,000 overcharging stations will be built in 300 cities across the country to penetrate prefecture-level cities and achieve full coverage.

On the day of the press conference, the “Global Charging Speedworld recordIn the “Challenge” live broadcast on the whole network, the AION model equipped with super-speed battery technology, under the certification of the world record certification officer, achieved a brilliant result of 5 minutes of charging and a full range of 207 kilometers, setting a record for the history of pure electric vehicles in one fell swoop. Speed ​​world record.

The release of GAC Ian’s super-speed battery technology and A480 super-charged pile has also attracted a lot of comments from industry experts. Cui Dongshu, secretary general of the National Passenger Car Market Information Association, said: “The implementation of GAC Ian’s super-speed battery technology and the A480 supercharger proves that pure electric vehicle charging can be as fast as refueling, and mileage anxiety will no longer be in the future. It is a problem that plagues users, and more consumers will actively choose to embrace new energy vehicles.” Professor Zhao Fu of the School of Vehicles and Transportation of Tsinghua University and Dean of the Institute of Automotive Industry and Technology Strategy said: “The cruising range is anxious and the charging time is long. Etc. is still the core issue that plagues the development of electric vehicles. GAC’s super-speed battery technology and the launch of A480 supercharged piles provide effective solutions to such problems. It is worth looking forward to!”

In November last year, the General Office of the State Council issued the “New Energy Automobile Industry Development Plan (2021-2035)”, which pointed out the need to accelerate the construction of charging and swapping infrastructure and strengthen new charging technologies such as intelligent and orderly charging, high-power charging, and plug-and-play charging. Research and development to improve charging convenience and product reliability. As the world’s only new energy brand with both battery-end and pile-end overcharging technologies, GAC Aeon is promoting the industrial development of super fast charging through self-developed technological innovations in the power battery field, bringing users “charging and refueling”. “Just as fast” charging experience.

However, it is not enough for GAC E’an to achieve the goal of “carbon neutrality by 2030 and 2060”. GAC E’an also expressed its willingness to open its arms and discuss peace with more partners and social forces at the event. Share super-speed battery technology and A480 super-charged piles, realize deep linkage between upstream and downstream of the industry chain, promote the accelerated development of China’s new energy industry, and jointly create a better green and smart mobile life.
