Motor performance is the key to breaking new energy
At present, new energy vehicles have become a hot spot in the automotive market. However, most new energy vehicles have a problem of short accumulation of technology and insufficient performance in electric drive. This means that there are only new breakthroughs in drive technology. Energy vehicles can form the competitiveness of comparable fuel vehicles.
In the future window of the new energy vehicle from the R&D concept to the large-scale market entry, who can master the core motor technology with independent intellectual property rights, who can occupy the technical high ground under the challenge of accelerating the reshuffle in the industry. New energy vehicle manufacturers who hope to break through the power of new energy vehicles certainly have challenges and innovators, but from the current solutions that have been formed, the application from 1-2 motors to 3-4 motors is considered to be a very rich one. The direction of the future, and there have been manufacturers from the new forces to release the 4 motor program - the Chinese background, but the technology research and development center in Silicon Valley, and the industry's first four motor drive technology SFMOTORS.
"Nothing out": The mainstream status of new energy vehicle motor drive
In the era of rapid development of new energy vehicles, the concept of electric drive of major auto manufacturers emerges endlessly, BYD Don's "Fast Speed Four-wheel drive", Lexus' "E-FOUR", Mitsubishi's "Double Motor 4WD", Tesla's " Dual-motor all-wheel drive, etc., but the common point is single or dual motor. Single-motor and dual-motor can be combined with one drive shaft or one motor for each of the front and rear drive axles for simple all-wheel drive. Although the structure is simple, both the R&D cost and the manufacturing cost can be effectively controlled, but it also brings lower transmission efficiency problems, which will affect the vehicle's pure electric range to some extent.
Experts pointed out that although its technical difficulty and excessive cost are still the key to restrict the performance of electric vehicles to improve performance, only the successful use of 4 motors represents that electric vehicles can compete with fuel vehicles in terms of power performance. However, only systematically study the vehicle dynamics and cooperative control mechanism of each motor under complex and multi-conditions, establish the vehicle dynamics model and the cooperative control algorithm, and establish the scientific mechanism of dynamics and coordinated control between the driving hubs. Achieve the possibility of synchronous operation of four motors. This is a big challenge for both new and old car companies.
