Using Hair-pin flat wire winding technology, the slot full rate is increased by more than 20%,the higher motor power density and the smaller volume releases surging power
The high-rigidity design of the rotating system adopts the third-generation carburized rare-earth material and matches with high-speed bearings to increase the speed
The high-resistance magnetic double-layer magnetic circuit design is adopted, and the better heat dissipation capacity of the flat wire motor is used to greatly improve the peak output capacity of the motor
The new generation SiC technology, coupled with high-efficiency permanent magnet synchronous flat-wire motors, combined with intelligent control strategies and optimized water flow control strategies, achieves a system peak efficiency exceeding 95%, operating efficiency above 91.7%, and an increase in range of 4-6%.
Motor Electromagnetic Optimization
Gear modification and active noise reduction technology result in an all-condition noise level for the electric propulsion system of less than 78dB, achieving an industry-leading standard.
Active damping in conjunction with harmonic injection, combined with algorithmic innovation for optimizing power output strategies, results in a smooth driving experience.
The electric drive system includes an intelligent disconnector-combination system, which supports lightning switching of the whole vehicle, realizing full-time two-wheel drive, timely four-wheel drive, and full-time four-wheel drive. Three drive modes are selected in all scenarios, which is efficient and energy-saving, and has a longer battery life
The motor controller directly integrates the dynamic torque control unit to shorten the response period and quickly stabilize the body. Quickly obtain the best traction to maintain vehicle stability on icy and snowy roads and wet and slippery roads in rainy seasons
Using the physical characteristics of the motor and battery, static heating, dynamic heating, and pulse oscillation heating are realized, and adaptive adjustment technology is adopted to intelligently match user needs. Improve the cruising range, shorten the charging time, and bring the perfect winter travel experience
