New Energy Vehicle Expert Says It Will Not Buy New Energy Vehicles

On June 1, a new energy subsidy was introduced, and the subsidy amount of up to 60,000 yuan made many people excited. But there are still different views in the industry on the direction of private purchases of new energy vehicles. This also includes the famous domestic new energy sources. Auto experts. Before and after the introduction of the subsidy policy, the author heard some different voices.

Chen Quanshi: I will not buy new energy vehicles

In response to the currently hot new energy subsidy policy, Chen Quanshi, Director of the Electric Vehicle Branch of the China Engineering Society, Executive Director of the Automotive Engineering Society of China, and Deputy Director of the State Key Laboratory of Automobile Safety and Energy, held in Shanghai on May 28th at the New Energy Automobile Development Summit Forum in Shanghai. It was stated that the country's policy of promoting electric vehicles and new energy vehicles is solid. But when the author asked if he would buy a new energy vehicle, Professor Chen Quanshi said: "No."

"I myself will not buy new energy vehicles," Chen Quanshi said, not only the price issue, but also the quality, driving mileage, car environment and so on. He told the author that he would not go to buy a car himself. Try to use new energy vehicles. "People tend to get together when they buy a car. It's a good choice. At least, this proves that most people are buying cars and their reputation should be good."

For, before the country announced the four core standards of electric vehicles, there is public opinion that the scope of the standard opinion is relatively narrow. Chen Quanshi believes that this interpretation is misunderstood. He said that the standard fully complies with our national standard setting norms, and has been hung on the Internet for a month to solicit Opinions. Only few domestic companies responded. On the contrary, foreign-funded enterprises and joint ventures were very active. Some companies provided 32 opinions and some of them made good comments. Chen Quanshi called for enterprises to be concerned about standards and should actively Opinion, don't go beyond the standards and blame.

Song Jian: Electric vehicles are not "low carbon"

On the morning of June 3, he heard a radio interview with Professor Song Jian, executive vice president of the Institute of Automotive Engineering at Tsinghua University. He said that pure electric vehicles are not energy-efficient. As China’s current electricity configuration is mainly coal-fired, nuclear power and water and electricity are only A small part, therefore, from this point of view, pure electric vehicles, driven by electricity, are still consuming energy, and are not "low carbon."

Professor Song Jian explained that currently the electric energy of electric vehicles mainly comes from thermal power generation. From the perspective of energy sources, it does not achieve the effect of emission reduction. “The thermal power generation is based on coal-fired power generation, which means that the electric energy of electric vehicles is 100% derived from carbon. Unlike gasoline and diesel, there is hydrogen in addition to carbon, which produces water after combustion.” Song Jian said: “According to the statistics of the Japan Energy Research Institute, the energy conversion efficiency of gasoline vehicles is 12%, and that of diesel vehicles is 15 %, electric vehicles are between the two, is 14%, efficiency is not high. In this way, the same distance, the carbon emissions from electric vehicles may be more than ordinary cars."

Professor Song Jian pointed out that pure electric vehicles are more suitable for use in parks and other large public places as ferry vehicles, but as private cars, pure electric vehicles are not the best choice for energy conservation and emission reduction.

Huang Xiangdong, deputy general manager of GAC Group, once expressed such views in public. He stated that as a charging source, China’s electricity is actually a “black” coal-fired power. Huang Xiangdong said that 80% of China’s electricity is currently supplied by coal. Every ton of coal burned will produce 2.7 tons of carbon dioxide. He quoted the US Department of Energy data that if you fill a car with 1 liter of oil, about 30% of the energy becomes the mechanical energy of the gasoline engine, and the rest is wasted because of overcoming resistance. "But at present, 400 grams of standard coal is used to produce electricity once. Only 30% of coal's energy becomes electricity. How much can we use to convert into mechanical energy?" Currently, BMW, Nissan and other pure electric vehicles consume more than 20 degrees of electricity. One hundred kilometers, Huang Xiangdong pointed out that from the carbon emission is not better than the traditional car.

"At present, China must vigorously promote pure electric vehicles. I think it is necessary to study carefully." Huang Xiangdong said that pure electric vehicles, PLUG-IN (plug-in) vehicles or "coal burning" vehicles, the only advantage is that fuel is cheaper, but Also need to increase 4 ~ 5 times the charging station to meet the demand, the social cost is very large.

New energy auto experts will not buy new energy vehicles themselves, and they do not support private purchases of new energy vehicles. For the promotion of private purchase of new energy vehicles, it is worth pondering.
