In recent years, the energy-saving and new-energy automotive industries in various places, especially the 88 demonstration cities, have flourished. They have shown good development and accumulated some valuable experience. At the same time, they have also appeared in the technological path, policy orientation, infrastructure, and business. There are some outstanding issues that need to be solved in terms of models and industry standards. At present, the development bottlenecks of new energy vehicles based on electric vehicles are mainly reflected in the two aspects of rechargeable batteries and charging piles.
January 8-9, "EV-Talk international energy-saving and new energy automobile industry development and key parts and components jointly sponsored by China Electrotechnical Society, Beijing Sinosteel Sifang Convention and Exhibition Co., Ltd. and Beijing Guohong Enterprise Research Information Technology Co., Ltd. The "Technical Standards Symposium" (hereinafter referred to as EV-Talk) was held in Beijing.
There is huge room for development in the domestic market
In 2012, China proposed the main strategic orientation of pure electric drive for the development of new energy vehicles and the transformation of the automotive industry. Its overall goal is: By 2020, the cumulative production and sales of new energy vehicles will exceed 5 million. Although there are various disputes surrounding the development of new energy vehicles, as an important strategic emerging industry determined by the State Council, new energy vehicles are still one of the most important areas of development potential in China.
According to EV-Talk, in recent years, the energy conservation and new energy automotive industries in various places, especially in 88 demonstration cities, have flourished, showing good development trends, accumulating some valuable experience, and also appearing in the technological path. There are some outstanding issues that need to be addressed in terms of policy orientation, infrastructure, business model, and industry standards.
In 2014, the domestic new energy automobile market ushered in the development of real industry significance, and the market situation of some popular models gradually opened up.
In response, Ye Shengji, deputy secretary-general of the China Association of Automobile Manufacturers, who participated in EV-Talk, pointed out that as the country has introduced a series of policies to support the development of new energy vehicles, some protection-oriented local measures are gradually dissipating, and local policies are also in the industry. The idea is consistent, so in 2015 China's new energy automobile market will usher in a better development.
Regarding the development environment of China’s new energy vehicles, Li Weili, senior economist and director of the manufacturing division of the National Information Center, also pointed out that although China’s new energy vehicles have achieved a good momentum of growth in 2014, they have reached the Netherlands, Norway, and the United States. Compared with Japan, Germany, and other countries, the proportion of electric passenger cars in sales of new cars is still very low, only 0.2%, which is more than double the gap between Germany's 0.4%, Japan's 0.6%, and the United States’ 1.5%. The 5.1% in the Netherlands and 5.5% in the Netherlands have a huge percentage gap.
From the perspective of the domestic new energy automobile consumption field, the current public-use car still accounts for 64% of the bulk, and the private car sector only accounts for 35%, which still has a lot of room for development.
Li Weili believes that the scope of demonstration and promotion of new energy vehicles is constantly expanding, covering almost all regions that are currently eligible for promotion.
Judging from the national guidelines for the promotion and application of new energy vehicles, including policy systems, business models, promotion assessment systems, charging facilities, product quality supervision, and the elimination of local protection and many other aspects, there are still many issues in the field of new energy vehicles. Explore and keep practicing.
Charging infrastructure becomes key
At present, the development bottlenecks of new energy vehicles based on electric vehicles are mainly reflected in the two aspects of rechargeable batteries and charging piles.
When talking about the development of power batteries, Dr. Wang Fang, chief expert of the China Automotive Technology and Research Center, said that the development and application of electric vehicle power batteries must be based on safety as the first factor, and their evaluation in the development, application and industrialization process is extremely high. important. All related companies should proceed from the integration and actual use of the vehicle, conduct in-depth careful and effective test and evaluation of the battery, and integrate the battery with good performance through the integration technology to further enhance its safety and comprehensive performance and promote the health of the power battery industry. Rapid development will promote the industrialization of electric vehicles.
For the development of the charging pile, a survey from Zuozian Production and Research shows that the ratio of electric cars and charging piles in Shanghai is 1:0.64, and that in Xi’an is 1:0.97. This ratio in Tianjin is close to 1: 1. Internationally, it is believed that to ensure the smooth development of electric vehicles, the ratio of cars to piles should be around 1:2.5. Therefore, in order to vigorously develop new energy vehicles in major cities in China, there is still much to be done in the construction of charging piles.
Li Weili also believes that the private distribution of charging piles requires multiple departments to participate in the management, coordination is difficult, and the complexity is high.
Taking Beijing as an example, the installation conditions of charging posts in private communities are currently imperfect and it is difficult to effectively solve them in the short term. Surveys conducted by the National Information Center have also revealed that at least 50% of consumers in Beijing do not meet the installation requirements for charging piles.
Fortunately, from a single model point of view, the domestic new energy vehicles can generally meet the basic travel needs of some consumers.
Li Weili said that taking a domestic plug-in hybrid vehicle as an example, its pure electric cruising range is 70 kilometers, the acceleration of 100 kilometers is 5.9 seconds, the average fuel consumption per 100 kilometers is 1.6 liters, and the performance is relatively outstanding; currently two of the vehicles are The price after the subsidy for each version of the model is respectively 120,000 yuan and 140,000 yuan, and the average consumer is basically acceptable. In addition, the vehicle provides a 6-year/150,000-kilometer vehicle warranty and a lifetime battery warranty, basically eliminating consumer worries.
For the future development, Ye Shengji said that the following bottlenecks still exist in the promotion of new energy vehicles: First, the key core technologies of new energy vehicles are not fully mastered, the ability of engineering is insufficient, and breakthroughs in key core technologies require great effort; Second, the society The supporting system is still not perfect, the industrial chain has not yet been fully formed, which severely restricts the market consumption of new energy vehicles. Third, consumers' awareness of products needs to be improved.
Han Yi, the deputy secretary-general of the China Electrotechnical Society, believes that China’s new energy industry is currently undergoing a key stage from the introduction period to the growth period. With the support of relevant policies, the marketization of energy-saving and new energy vehicles will surely usher in 2015. The new peak. In this regard, Li Weili also said that in 2015 China's new energy vehicles will continue to maintain rapid growth, and sales are expected to exceed 100,000 vehicles.
