China Top Innovative Intelligent Carmaker’s Analysis on Technology, Development, Challenges of New Energy Vehicles

At the main forum of the 8th China International New Energy Conference and Industry Expo hosted by SMM, Song Yilin, vice president of Leapmotor, expressed his views on the existing technologies, future development trends and challenges of new energy vehicles.

SMM Overseas Marketing Dai Luanjie: In the new energy vehicle segment, technologies of motors, electronic controls and batteries have made great progress, what is the current development of existing technologies? And what are the future development trends and challenges?

Song Yilin, Vice President of Leapmotor: The current technological development, in the past 10 years, especially in the past 5 years, including batteries, motors, and electronic controls, has been very mature, driven by our Chinese market.  More than 80% or even more of global batteries and cells come from China. Most of the components of electric vehicles are domestically produced, so domestic battery technology has developed very rapidly in the past 10 or 5 years, and domestic electric vehicle technology is at the forefront of the world.

From the perspective of challenges, the motor and electronic control must achieve high performance and low price. In terms of detailed technology, the motor pursues high power; the production line of flat wire is currently a bit difficult in China, and the flat wire winding needs to import high-end automatic production lines from abroad; the process cost of flat wire is high, and it will take time to mature.

In terms of batteries, the first thing to do is to improve the quality, and the second is how to minimise the cost. Electric vehicles are far more competitive than fuel vehicles. Lithium iron phosphate is widely used. Only by improving the quality from the raw material end to the battery cell can there be a good product, so as to reduce costs.

Further development is required in fast charging, and it is recommended that material factories and battery factory speed up the development speed. From the perspective of the system, the future is that the battery is highly integrated with the body, and at the same time it is convenient for maintenance and disassembly. Generally speaking, electric vehicles must have high performance and better cost performance in order to make electric vehicles more competitive.
