8 minutes to charge 1000 kilometers: GAC, a billionaire giant, hits the daily limit, and an academician angrily denounces it as "must be a liar"

In the past two days, a piece of news about GAC New Energy Vehicle has caused controversy in the market.

Last Friday afternoon, GAC Aion, a subsidiary of GAC Group (13.480, 0.96, 7.67%), released a preview of its new power battery technology.

The new battery uses graphene technology. The graphene-based super-fast charging battery can be fully charged to 80% in 8 minutes. At the same time, the silicon negative electrode battery allows the electric vehicle to have a NEDC range of up to 1,000 kilometers.

Stimulated by this news, GAC Group's A shares rose from the red to the daily limit on Friday. GAC Group's Hong Kong shares closed up 19.49% last Friday.

However, this technology has been questioned by the market and called a scam.

Let's see what happened

80% charge in 8 minutes!

The battery industry welcomes "black technology" again

Zeng Qinghong, Chairman of GAC Group, said that GAC's graphene-based super-fast charging battery has now entered the mass production test stage of actual vehicles. The first model to be equipped with it is AION V, and it is initially scheduled to be mass-produced in September this year. This is the second time that the domestic battery industry has ushered in "black technology" after NIO attracted market attention with its "solid-state battery" this month.

On January 15, GAC Aion released a poster stating that its models equipped with graphene-based super-fast charging batteries can be charged to 80% in 8 minutes, and the NEDC standard range reaches 1,000 kilometers;

On January 13, Zhiji Auto announced that its first model will cooperate with CATL (388.990, 8.44, 2.22%), equipped with "silicon-doped lithium-supplemented" batteries, with a maximum range of more than 1,000 kilometers;

On January 9, NIO released a 150kWh solid-state battery, saying that models equipped with this battery can achieve a NEDC range of 1,000 kilometers.

Stimulated by the news, on January 15, GAC Group's A shares closed at the daily limit; Hong Kong stocks also rose simultaneously, closing up 19.49% for the day.

Data shows that GAC Aion New Energy Automobile Co., Ltd. was established in July 2017, with Feng Xingya as the legal representative and a registered capital of RMB 141.897 million. Its business scope includes technology transfer services related to new energy vehicles, technical consulting services related to new energy vehicles, and technology research and development services related to smart connected vehicles. The company is wholly owned by A-share listed company GAC Group.

Academician of the Chinese Academy of Sciences: Electric vehicles can run 1,000 kilometers and be fully charged in a few minutes

It must be a lie

On January 16, at the China Electric Vehicle Hundred People Forum (2021), Ouyang Minggao said: "If someone tells you that this car can run 1,000 kilometers, can be fully charged in a few minutes, is very safe, and has a low cost. Based on current technology, he must be a liar."

Ouyang Minggao believes that human society is currently in the third energy revolution with batteries as the core, renewable energy as the main body, electricity and hydrogen as the carrier, and electric vehicles as the tool. Electrification is a major technological change in automobile power over the past century, and lithium-ion batteries are a major revolution in energy utilization over the past century.

Ouyang Minggao said that for new energy vehicles, the core technology of efficient thermal management system has made important breakthroughs, which will reduce the range loss in low temperature environment in winter by 2/3 compared with existing models. The integration technology of vehicle energy efficiency optimization has also made breakthroughs. The power consumption of small pure electric vehicles in NEDC working condition test is close to 10 kWh per 100 kilometers. At the same time, the construction of charging system and fast charging technology have made breakthroughs. In the next 5-10 years, 75% of the power can be fully charged in 15 minutes during the day.

Through research, Ouyang Minggao believes that among renewable resources, the price of photovoltaic power generation is comparable to that of coal-fired power generation; distributed energy has formed scale; various charging technologies in charging infrastructure are mature and compatible, and the infrastructure is relatively popular, meeting the needs of electric vehicles; in the energy Internet, mainstream V2G technology and mainstream business model suitable for China's national conditions have been formed, and the industry has entered a growth stage.

"With the strong support of various technological breakthroughs, new energy vehicles are about to usher in a critical turning point for all-round breakthroughs," said Ouyang Minggao.

GAC Aion responded:

Theoretically, it can charge 1,000 kilometers in 8 minutes

Today, Gu Huinan, general manager of GAC Aion New Energy Automobile Co., Ltd., responded at the same forum. He emphasized that new energy vehicles with a range of 1,000 kilometers will definitely appear this year, but the cost will not be low.

"Cars with a range of 1,000 kilometers will definitely be released this year, and fast charging will also definitely be released. It is theoretically possible to fully charge a car for 1,000 kilometers in 8 minutes." Gu Huinan, general manager of GAC Aion New Energy Automobile Co., Ltd., said at the China Electric Vehicle 100 Forum today, responding to outside doubts about its vehicles with a range of 1,000 kilometers.

He said that if a battery can be charged for 1,000 kilometers in 8 minutes, high-power fast charging piles need to be built, which is technically feasible, but the cost is high. GAC Aion will promote it at a pace. At the same time, the battery technology that combines the two technologies will be launched at the end of the year at the earliest.

Gu Huinan, general manager of GAC Aion, said at the online forum of the Electric Vehicle 100 Forum today that everyone should pay attention to what Ouyang Minggao said and not misunderstand it. He said he wanted this and that and wanted it to be cheap, which is definitely impossible. The 8-minute fast charging is not only about the battery, but also about the charging pile. Don't confuse technological breakthroughs with commercial promotion issues.

I took a look at Tesla's official website and found that even the flagship luxury sedan, the Model S, can only be charged for a maximum of 270 kilometers in 15 minutes with super-fast charging.
