By the end of 2021, the cumulative sales of new energy vehicles in the world had exceeded 16 million, accounting for more than 50% in China. At present, China's new energy vehicle technology continues to break through, the products are increasingly rich, and the market penetration rate is steadily rising.

However, new problems and challenges are gradually emerging. How to promote the comprehensive market-oriented process of new energy vehicles? How to ensure the safety and stability of the supply chain of the automobile industry chain? How to solve the energy supplement problem of new energy vehicles? How can China's new energy vehicles run out of "acceleration"?

The 2022 World new energy vehicle conference officially ended on the 28th. Many experts gave their own answers to the above questions.

Will a total ban on the sale of fuel vehicles be put on the agenda?

At present, further promoting the marketization of new energy vehicles has become an important task of industrial development, and when to ban the sale of fuel vehicles has also become the focus of debate in the industry.

Under Secretary General of the United Nations Achim Steiner revealed that more than 40 countries in the world have made a commitment to stop the sales of internal combustion engines by 2050.

Zhu Huarong, chairman of Chongqing Changan Automobile Co., Ltd., said that China's new energy automobile industry has moved from the original stage of technology tasting and policy guidance to the stage of mass popularization, and has gradually become an important force supporting the development of China's automobile industry.

Therefore, he believes that China's automobile industry has initially met the basic conditions for stopping the sale of fuel vehicles, and he suggests further accelerating the pace of transformation and putting the stopping of the sale of fuel vehicles in China on the agenda.

As a matter of fact, there is a precedent in China to stop the sale of fuel vehicles. Hainan Province recently proposed to completely ban the sale of fuel vehicles on the whole island by 2030. Hainan became the first province in China to ban the sale of fuel vehicles.

In this regard, Feng Fei, deputy secretary of the Hainan provincial Party committee and governor, said at the meeting that he would create a zero carbon demonstration zone of Boao Dongyu island and take the lead in using all new energy vehicles in the zone; Create a high-level commercial application scenario of intelligent connected vehicles on the tourism road around the island.

Supply shortage? Good steel for good blades!

Affected by multiple factors, the new energy vehicle industry chain and supply chain have broken points. On the one hand, the prices of lithium, cobalt and nickel have soared, and the supply is insufficient. On the other hand, the shortage of chips has not been completely alleviated. How to achieve stable price and supply is an important problem facing the industry.

Chen Hong, chairman of Shanghai Automotive Group Co., Ltd., believes that it is necessary to study how to optimize the macro-control of lithium, cobalt and other resources while allocating resources in a market-oriented manner, "so that good steel can be used in a good blade". For industries with low energy density requirements, we should encourage the exploration and application of non lithium batteries such as sodium and magnesium, so as to release more lithium resources for vehicle use and alleviate the current resource shortage and soaring prices.

In view of the shortage of chips, Wang Shengyang, founder, chairman and general manager of nano chip microelectronics, said that the localization of automotive semiconductors is of great significance to the development of China's automotive industry. In the future, China Semiconductor really wants to gain a foothold in this industry. It can not only replace imported products, but also consider how to cooperate with downstream industry chain customers to jointly define the future oriented automotive electronic and electrical architecture.

Endurance anxiety? There are new ways to replenish energy!

For a long time, new energy vehicles have been faced with the dilemma of energy supplement, and the construction of public charging infrastructure network is unbalanced and insufficient.

Zhu Huarong frankly said that China's energy replenishment infrastructure still needs to be continuously improved, and the growth rate of charging and replacing facilities still lags behind the development of new energy vehicles.

In the view of sun Fengchun, an academician of the Chinese Academy of engineering and a professor of Beijing University of technology, electricity exchange is one of the important ways to develop new energy vehicles in the future.

Zhu Huarong added that China urgently needs a breakthrough in a new generation of batteries. We should focus on the key breakthroughs of positive and negative electrode materials and electrolyte, change from structural innovation to material innovation, and fundamentally solve users' charging anxiety, safety anxiety and use environment anxiety. It is recommended that enterprises, scientific research institutes and universities strengthen cooperation to accelerate the research, development and application of new generation batteries.

In the view of Zeng Yuqun, founder, chairman and general manager of Ningde Times New Energy Technology Co., Ltd., advanced battery technology is the basic support for comprehensive electrification. In the exhibition area of the conference, the single chocolate battery block developed by Ningde times can change power for about 1 minute, and the single battery can provide a battery life of about 200 kilometers.
