Where is the gap between domestic motor technology and foreign countries?
With the development of technology in recent years, domestic motor vehicle passenger car drive motor technical indicators continue to maintain international advanced, commercial vehicle drive motor technical indicators to maintain international leadership, motor controller indicators are rapidly catching up with similar foreign products. Where is the gap between domestic motor technology and foreign countries?
Luo Jian told the electric vehicle resource network reporter that the gap between the domestic motor technology level and foreign countries is mainly reflected in the basic materials. In terms of motors, domestic silicon steel, NdFeB and bearing technologies lag behind the international level; in terms of controllers, there is a gap between wafer technology and foreign countries.
Luo Jian also said that with the rapid development of the new energy automobile industry in recent years, China has become the world's largest market for electric vehicles, and China is also increasing basic scientific research. For example, the Electric Works has jointly developed the SIC module with Shanghai Road. The controller with a power density of 40kW/L is designed, which represents the highest level of current SIC in China.
What is the future development trend of new energy vehicle motors?
First of all, the new energy vehicle motor market is huge. According to the data of China Automobile Association, in 2016, China produced 517,000 new energy vehicles and produced 794,000 vehicles in 2017. It is expected to exceed 1 million in 2018 and 2 million in 2020. As can be seen from the above data, the new energy vehicle motor market is large enough in the next few years.
Second, multiple modes of cooperation will coexist. At present, the new energy vehicle industry continues to heat up. The 2020 national fuel consumption regulations will encourage Chinese automakers to increase their investment in the drive motor industry and achieve their mastery of the drive motor industry through independent design or joint venture cooperation. At the same time, in order to further stabilize market share, traditional drive motor enterprises will increase investment in powertrains, improve powertrain integrated design and control capabilities, and increase sales through powertrain sales. Therefore, the new energy automobile motor industry will present a development trend of multiple cooperation modes.
Third, the manufacturing model shifts to a single product in large quantities, reducing costs. Starting from 2016, the state will speed up the subsidy rate of new energy vehicle subsidies, prompting the whole vehicle enterprises to reduce the cost of parts procurement. Judging from the demand of foreign passengers, the target cost of passenger electric drive system after 2020 is extremely low, even lower than the procurement cost of similar products in the domestic market. In order to adapt to the market, new energy automobile motor enterprises will shift from flexible production mode of multiple varieties and small batches to high-volume manufacturing mode of single products, and put into automated production lines to reduce product costs.
