Technical Analysis of New Energy Vehicle 2.0 Era
In the new energy vehicle 2.0 era, the core technology innovation will become extremely important, and the battery core technology is related to the lifeline of China's new energy vehicles.
The hollow core technology of traditional fuel vehicles has always been the pain of China's auto industry. However, the hidden dangers of the core technology of new energy vehicles have been traced. If you don't master the battery core technology, China's new energy vehicles may repeat the mistakes of the traditional automobile joint venture company.
The following is mainly from the various aspects of technology, including the development of our current three models at home and abroad, the main key components and the development of our energy-saving components for everyone to sort out.
Power battery: power battery research and development and industrialization: Germany, the United States, China, Japan and Korea. Lithium-ion power battery production is currently mainly concentrated in China, Japan and Korea.
Japan is still leading the way in technology; South Korea has the largest market share in terms of market share; China has the largest number of battery companies and the largest capacity.
Key materials for power batteries: Basically achieved localization; monomer technology is basically at the same level as foreign countries; a relatively complete lithium-ion battery industry chain system has been formed, mastering the formulation design, structural design and manufacturing process technology of power batteries The production line gradually transitions from semi-automatic pilot to fully automated large-scale manufacturing; product uniformity, system integration technology, and production automation: it is necessary to catch up.
Pure electric vehicles: In the past two years, there were more pure electric vehicles in foreign countries, and there were fewer domestic ones. However, through the development of these two or three years, the overall level of domestic pure electric vehicles is still developing very fast. Compared with foreign countries, the whole technical level is shortened to 2-3 years according to our estimation and budget, and foreign products may only be worse than the development cycle of half-generation products. There are some performances that are comparable to those in foreign countries, like power performance, and have a very good cost advantage.
At the same time, for pure electric vehicles, the key indicators and the typical models of foreign countries still have various gaps. The next step is also a focus of domestic or nationally supported electric vehicle technology upgrades.
For pure electric vehicles, the application of new integrated chassis and integrated intelligent technology and lightweight technology will gradually increase in the future. According to the Automotive Engineering Society's research on foreign vehicle companies, the amount of technology applied in the next generation of product reserves will be greatly improved.
Pure electric commercial vehicles: China is undoubtedly at the forefront of the world in the world. A variety of energy supply technologies are unique, and the overall technical level has reached international advanced level, and the industrialization capability is internationally leading.
In terms of safety, it has broken through key technologies such as key component protection, thermal management, and structural safety, and solved safety and reliability issues such as wading safety.
Plug-in hybrid car: This model has attracted a lot of attention in the past few years. One is plug-in type, and the other is a hybrid-based plug-in car. They are all hybrid-specific engines. A relatively efficient one-stroke gear is used, and the control is more difficult.
Fuel cell vehicles: In 2011, the China Automotive Engineering Society made a judgement and estimation of various models. The fuel cell vehicle is still in a small-scale demonstration stage, but with the internationally large vehicles in these two years. With the introduction of industrialized vehicles, the advancement of fuel cell vehicle technology has accelerated, and leading products have already possessed industrialization capabilities.
