New energy vehicles have become a hot trend in China's future auto industry. In recent years, the state and relevant departments have vigorously advocated energy-saving and emission reduction. The launch of new energy vehicles has attracted the attention of many auto and component companies. Vehicle companies, parts and components companies, and companies that are not in the automotive industry are eager to invest heavily in support. , Join the new energy automotive industry. What followed was the concern of people in the related parts and accessories industry.
From the perspective of the industrial chain of new energy vehicles, the beneficiary end may be mainly concentrated in core components, and the companies with strong resource control in the upstream resource end will also benefit. Because: First, the battery is the biggest bottleneck in the current technology and cost of new energy vehicles; Second, due to the scarcity of mineral resources, lithium, nickel and other upstream resource companies will also have greater profits; Third, vehicle manufacturers are currently compared For those who are confused and have no definite monopoly advantage, they should first pay attention to those who own core technologies or have technically mature and commercially available models.
The electronic control system is the brain of the electric vehicle and directs the operation of the electronic components of the electric vehicle. The vehicle-mounted energy system is the core technology in the electronic control system. It is a link between the battery, the battery pack and the vehicle system, including the battery. Management technology, on-board charging technology and DCDC technology and energy system bus technology. Therefore, the on-board energy system technology has increasingly become an important direction for industrial application technology research, and it has increasingly become an important symbol of industrial development. At present, this technology has become an important bottleneck restricting the convergence and development of the electric vehicle industry chain.
“The industrialization of key parts and the localization of basic raw materials are the key and bottlenecks for the development of new energy vehicles in China.†Li Wanli, researcher of the Industrial Policy Department of the Ministry of Industry and Information Technology, said that China’s new energy vehicles are supported by the Ministry of Science and Technology. Through continuous research and development during the “10th Five-Year Plan†and “Eleventh Five-Year Plan†period, significant progress has been made in both research and development capabilities and the number of applications, and small-scale demonstration operations have been conducted.
New energy vehicles have seen signs of a transition from R&D to industrialization. Major auto parts companies, such as key automotive companies and power battery, drive motors, controllers, etc., have grown and expanded in several years of promotion and demonstration work. They have introduced a series of performance requirements. Products, but as the common key technologies such as drive motors, batteries and other key parts and components, their main indicators of reliability, cost, and durability cannot meet the development needs of new energy vehicles and become the major constraints for the development of new energy vehicles.
In fact, after many years of research, the core technologies of key components for new energy vehicles in China have achieved breakthroughs: At present, China's independently developed Ni-MH, Li-ion power batteries have significantly increased energy density and power density, and are close to the international advanced level; The following 200kw permanent magnet brushless motors, AC asynchronous motors and switched reluctance motors have a weight ratio of more than 1300w/kg, which is matched with the entire vehicle.
However, compared with developed countries, China's new energy vehicle key component technology still has obvious deficiencies or gaps, such as the controller's power switching components and high voltage capacitors. Power batteries are a bigger bottleneck than motors. China's battery technology research and development, battery management system and product consistency, reliability, service life and industrialization degree are lagging behind. However, we have reason to believe that under the strong support of the government, China's new energy automotive motor has the most potential to become the center of industrialization in the world.
