Recently, the official implementation of the New Energy Subsidy New Deal has once again stirred up a spring in the new energy automobile circle. Shortly after the formal implementation of the New Energy Subsidy New Deal, Beiqi New Energy's EC series products reported the suspension of production and sales.
Beiqi New Energy's EC series products are also at the same level as the low-end mileage models such as the Zhidou D2 and Zhongtai E200. According to the headline APP survey, Zhidou D2 and Zhongtai E200 also have signs of suspension.
It should be pointed out that Beijiang New Energy's two EC series products, EC180 and EC200, each have a driving range of 150-200 km. The subsidy of the New Deal has precisely raised the high mileage and high energy density of new energy automotive products. The request.
The New Deal stipulates: Vehicles less than 150 kilometers in length will no longer be subsidized; subsidies for 150-300 kilometers for pure electric vehicles will be reduced by approximately 20%-50%; subsidies for models with cruising range of 300-400 kilometers and over 400 kilometers will be subsidized. Respectively increase 2% -14% range. In terms of the energy density of the power battery system, the lower limit of subsidies is increased from 90 wh/kg to 105 wh/kg, and for higher subsidies, the battery energy density needs to reach 120 wh/kg.
Under the stimulus of the New Energy Subsidy and New Deal, the mileage of the Geely Emgrand EV450, Emgrand Gse, BYD Song EV400, Qin EV450 and SAIC Roewe Ei5 that were listed this year have generally risen to more than 400 kilometers. It can be clearly felt that models with low cruising range are accelerating their exit, while the new energy vehicle market is moving toward the era of high cruising miles.
Both sides of the coin
As a policy-driven market for new energy auto industry, it is understandable for car companies to adjust product launches according to policies, which is also a great advantage for solving the pain points of consumption.
However, the rapid update iteration of new energy products is a double-edged sword. When the Chinese new energy market runs into the era of high cruising mileage, high endurance and high energy density also bring correspondingly high risks.
Today, the industry’s highest concern for new energy vehicle safety incidents is the frequent safety incidents of Tesla. According to incomplete statistics, since 2013, Tesla has had 34 accidents worldwide. In the first half of this year alone, Tesla made headlines due to battery fire accidents.
Just recently, the US National Transportation Safety Committee also disclosed that the Model S, which had been involved in a high-speed accident in Fort Lauderdale, Florida, on the 8th of May was already extinguished after a fire, but it caught fire twice.
As a representative company of new energy vehicles, Tesla has achieved industry leadership in terms of high endurance and high energy density, but it is bound to “fire.â€
In view of the recent cause of the Tesla accident, Dong Yang, executive vice president and secretary general of the China Association of Automobile Manufacturers and deputy chairman of the China Association of Automotive Engineers, sent an analysis. He said that Tesla's reason for the battery's frequent fire has two major reasons: First, Tesla is relatively technically aggressive, and its energy density is the highest in the world's electric vehicles. The energy density and safety of power batteries are contradictory, and the energy density is high, and the probability of natural accidents is greater. Second, Tesla’s concept of “iterative development†for the Internet, and the research needed for the application of new technologies in the automotive industry, Development and testing have not been carried out adequately.
In fact, Tesla's fire accident is not a special case of the development of new energy vehicles. In May 2017, 80 electric bus buses parked at the Beijing Crab Island Resort explode, and once raised the industry’s discussion on the safety of new energy vehicles.
Nowadays, the introduction of a variety of high-end mileage models that have benefited from the subsidy of the New Deal has suddenly alerted industry experts who have witnessed electric vehicle accidents.
How to solve the problem of battery safety?
Recently, experts in the new energy industry have also expressed the importance of the safe development of new energy vehicles. Dong Yang wrote that “The contradiction between energy density and security still exists, and safety is still the most important contradiction in the development of electric vehicles. This year, the government departments raised the threshold of energy density for electric vehicle subsidies, and safety accidents have also risen. The signs must be given attention throughout the industry."
Apart from Dong Yang’s strong emphasis on the development of new energy vehicles in the context of the article, it is not uncommon that, at the recently held “International Forum on Lithium Industriesâ€, Ouyang Minggao, executive vice president of the China Electric Vehicles 100, also bluntly The safety control of energy vehicles remains a challenge.
Experts pointed out that the contradiction between energy density and safety is not the development of new energy vehicles with high energy density and high cruising mileage. What they are emphasizing is that while upgrading the mileage of new energy, it is also necessary to consider the upgrading of battery technology. This guarantees safety.
Then, in the development of new energy, how to ensure product safety as much as possible? To evade Tesla's mistakes in development?
Dong Yang believes that compared to the exploration of traditional fuel vehicles in various fields of the automotive industry for more than one hundred years, the industry’s efforts to control new energy technologies are still far from adequate.
"For high-energy-ratio lithium-ion batteries, it is necessary to conduct in-depth research and study on the safety rules in the design and manufacture of battery cells, the design and manufacture of battery packs, and the design and manufacture of complete vehicles." Indicated.
The research and development, manufacturing, and production of various new energy technologies require a lot of time and effort to verify the practice. At the same time, policies and the up-and-down cooperation of upstream and downstream companies in the new energy industry are also needed.
Dong Yang appealed in the text, hoping that the government department “does not change the technical threshold of electric vehicles frequently and give enough time for the development of electric vehicles.â€
According to the development process of vehicle manufacturers, the research and development of new models of electric vehicles will take at least two years. Therefore, Dong Yang put forward three suggestions for the current New Energy Subsidy New Deal. First, do not change the technical indicators of the electric vehicle subsidies every year. Second, there are changes in technical indicators that need to be announced two years in advance in order to prepare companies; Third, the government departments In order to reduce the amount of subsidies, the amount of subsidies may be decremented each year without having to frequently propose new indicators.
In addition, as far as companies are concerned, Dong Yang called on all companies to make sufficient investments to provide consumers with safe and reliable electric vehicle products.
In order to further ensure the safe use of new energy vehicles, Ouyang Minggao also suggested: "I recommend evaluating the safety technology threshold for high-power DC fast charging. With a 350-kilowatt charge, the voltage of electric vehicles will increase to 1000 volts and charge. With a current of 350 amps, this will bring major technical challenges to the vehicle's electrical safety, battery safety, charging safety, and power grid safety. Therefore, we must fully consider China's national conditions and formulate scientific and reasonable charging technical standards."
Behind the loud voice of Dong Yang and Ouyang Minggao, the issue of safety in the new energy auto industry cannot be ignored. Even if the sales volume of new energy vehicles soars and the new energy scores hit record highs, the entire new energy market is showing signs of prosperity. However, it is still a long way from the maturity of the industry. Solving the safety issue of new energy vehicles is the only way for the development of new energy vehicles.
