China's all-electric vehicles




China must be cautious in developing China’s all-electric vehicles. First of all, China's all-electric vehicles technology is still immature, and the matching technologies for power steering, brakes, motors, air conditioners and vehicle systems are not perfect. China's all-electric vehicles have high requirements for light weight and safety, and it is difficult for small enterprises to meet the standards. Second, the grid, charging stations and billing systems required to operate all-electric and plug-in vehicles are not robust. It is still large groups that can really promote the development of China’s all-electric vehicles, including large automobile factories, large motor factories, large battery factories, and large-scale electric vehicle parts suppliers the mainstream.

It is understood that China's chemical battery industry has developed rapidly in recent years. Lead-acid batteries, lithium iron phosphate batteries, rare earth yttrium iron lithium batteries, nickel-metal hydride batteries, etc. "show their magic powers". There are hundreds of production enterprises, and enterprise standards are standardized. different. However, the industry currently only has 4 recommended national standards and 3 automotive industry standards, which cannot adapt to the rapidly developing electric vehicle industry. It is reported that as of November 2009, China has approved and released 36 national standards for China’s all-electric vehicles and automotive industry standards, 7 of which have been submitted for approval, and more than 30 projects are being developed and revised, including basic general standards, Standard for pure electric, hybrid and fuel cell vehicles and key components. The Electric Vehicle Sub-Technical Committee of the China Automobile Standards Committee and the Standardization Institute of the China Automotive Technology and Research Center have organized the formulation of 10 standards for the key components of China’s all-electric vehicles - a power battery. China has taken the lead in the development of China’s all-electric vehicles, especially vehicle batteries, but the formulation of electric vehicle standards, including various chemical batteries and charging station standards, is relatively lagging behind. 10 standards were formulated and approved, that is, they will be promoted and implemented in China.

The new battery technology has broken the bottleneck of the development of China’s all-electric vehicles. Lead-acid batteries are gradually replaced by advanced lithium-ion batteries, and the driving range and service life have been greatly improved. Despite the great progress in battery life, safety performance and energy density, there is no China’s all-electric vehicle company in China that has undergone large-scale and all-round real vehicle tests, and there are still many difficulties in producing high-performance, low-cost batteries. .

The previous large-capacity lithium-ion power batteries have poor overcharge resistance. The safety performance of lithium iron phosphate batteries is greatly improved, and the service life is longer. End users are important. Although China’s all-electric vehicles usher in a good opportunity for development, the current electric vehicle has not yet reached maturity, and its performance and price cannot be as balanced as traditional vehicles, which determines that it is still a market segment and cannot replace traditional vehicles in the short term. .It is not only batteries that hinder the development of China’s all-electric vehicles, but also motor control, vehicle matching, lightweight design, etc. It requires the common progress of various technologies such as power batteries, battery management, motor control, electronic devices, and new material applications to promote China’s all-electric vehicles. development.

BYD's all-electric vehicles


Hybrid vehicles are fuel-efficient vehicles, but at the end of the day they require fuel. China's all-electric vehicles and plug-in hybrid vehicles are true new energy sources with zero emissions. The energy used comes from the grid, which is of strategic significance for changing the energy structure of transportation. Since the "863 Plan", the state has been very supportive of the development of new energy vehicles, but because the battery technology in the 20th century has not progressed, the policy guidance effect is not good. The breakthrough of battery technology brings opportunities to promote the development of China’s all-electric vehicles, and we must still adhere to the "three verticals and three horizontals" strategy of the "863 Plan" on major special projects of China’s all-electric vehicles. Judging from the current situation, the industrialization of all-electric and rechargeable vehicles has been put on the agenda.

At present, the international oil price is rising, and the problem of energy saving and emission reduction is prominent. New energy vehicles have become a hot spot in the development of the global automobile industry. Whether from China or abroad, the development prospects of China’s all-electric vehicles are very good. Governments in many countries are pushing for electric vehicles, and the Obama administration in the United States has taken new energy vehicles as the development strategy of the auto industry. From a global perspective, the best carrier of electric vehicles is small cars, and the development of large-scale China’s all-electric vehicles is still very difficult. China has the resources and market environment advantages to develop China's all-electric vehicles. As long as the research and development efforts are increased, small China’s all-electric vehicles with reasonable prices, energy saving and environmental protection can be produced to meet the needs of urban low- and middle-income groups and the rural market. Therefore, the development prospects of China’s all-electric vehicles are very bright. The government's promotion can certainly drive the development of the electric vehicle market, but the large-scale promotion of China’s all-electric vehicles is also constrained by the high cost of the whole vehicle and insufficient infrastructure.

China’s all-electric vehicles are one of the important directions for the development of the world's auto industry, with broad market prospects. Regarding electric vehicle projects being launched in various parts of China, they cannot be allowed to develop freely, nor can they be suppressed. China’s all-electric vehicles should develop in an orderly manner under the guidance of policies. Judging from the current situation, China's all-electric vehicles are still in the stage of expanding the market, and enterprises have not yet mastered the key technologies for producing China’s all-electric vehicles. Electric vehicle manufacturers, parts suppliers, electric vehicle infrastructure suppliers and local governments should all take action to solidly promote the development of China’s all-electric vehicles. Of course, orderly development must rely on government organizations. For example, the demonstration operation of "10 cities, 1000 vehicles" has accumulated valuable experience for the development of new energy vehicles. The development of China’s all-electric vehicles should also learn from this experience. Jointly formulate standards and management methods. The orderly development of China’s all-electric vehicles requires the government to formulate scientific and reasonable industry standards and regulations, create a market environment conducive to the development of China’s all-electric vehicles, and promote the development of the entire electric vehicle industry through market competition.
