Whether the core technology of parts and components has become a "stumbling block" in the development of new energy vehicles


After the recovery of the economic environment, the development of China's auto industry has also continued to pick up with the market. Whether it is a joint-venture car company or an independent brand car company, they have begun to vigorously promote their new energy vehicles . Not only are they in a strong position, but some models have already reached volume production. However, some experts once believed that the development of new energy vehicles will encounter bottlenecks, especially in the core components and technologies of new energy vehicles . Currently, major companies have encountered more or less problems.

Although in recent days, the six ministries and commissions have recently issued the "Opinions for Promoting the Sustainable and Healthy Development of China's Automobile Products Exports", actively guiding the export of energy-saving and new energy automotive products, supporting the promotion of pure electric vehicles, and promoting the promotion of hybrid vehicles. However, professionals believe that the bottleneck of the development of new energy vehicles in the power battery, the current development of hybrid power should be the main, the marketization of electric vehicles still need time to nurture. The main components of new energy electric vehicles are power batteries, electric motors, and energy conversion control systems. However, the power batteries must achieve high performance such as fast charging and safety, and they have the highest technical threshold and the most concentrated profit. Li Shengmao, a researcher of China Energy Industry Consulting Group's new energy auto vehicle industry, pointed out that new energy vehicles have high requirements for batteries and must have high specific energy, high specific power, fast charging and deep discharge performance, and require low cost and long service life. Compared with the development of new energy vehicles in the world, China's development in new energy vehicle batteries has lagged behind the development of international new energy vehicles .

At present, Japan's lithium battery suppliers have a large advantage in the market, and have also begun to develop a unified battery specifications, safety standards and charging methods; the United States also in order to not rely on foreign lithium batteries, but also increase Lithium battery manufacturers support, approved 25 billion US dollars to promote the development of lithium battery manufacturing; European automotive companies in the green energy-saving environmental protection and hydrogen-powered vehicles, the development of more obvious advantages. Compared with the development of new energy vehicles in these countries, although Chinese car companies are lagging behind, with the strong support of the Chinese government, Chinese car manufacturers’ confidence in the development of new energy vehicles is also constantly increasing. From the strength of the new energy vehicle lineup displayed at the Guangzhou Auto Show this year, we can see the confidence of the development of new energy vehicles in China.

Although SAIC Motor has always been a model enterprise for the development of China's new energy vehicles , SAIC Motor also stated that its current advantages in many parts and components have not yet been established when it proposes the goal of listing Roewe hybrid vehicles in 2020 and 2012. However, it is understood that SAIC has its own development direction in the development of new energy vehicles, they will form their own battery management capabilities, battery industry chain and electric drive gearbox development, to form their own vehicle integration, including the new energy car's electric air conditioning , SAE and other new technologies such as ABS, SAIC must carry out a comprehensive layout. These layouts or will solve the new energy vehicles in the components, such as batteries, battery management systems, motors, motor drive control, including such as hybrid power drive with coupling function is the transmission and other difficulties.

The development of new energy vehicles requires a process. At present, the greater problem is the cost and core technologies. The relatively high cost and the lack of core technologies have affected the development of new energy vehicles.
