The electric drive system plays a crucial role in leading green travel in today's thriving new energy vehicle industry. Serving as the "heart" of electric vehicles, it efficiently converts electrical energy into mechanical energy to propel the vehicle. Consisting of components such as the electric motor, controller, and transmission unit, each part is indispensable in determining vehicle performance, range, and driving experience.
To evaluate an EDS system's excellence, key factors such as performance, efficiency, noise control, intelligence, and safety must be comprehensively considered. A superior system excels in all these aspects to deliver an ultimate driving experience:
1.Performance: High power, speed, and torque are pivotal metrics. They directly influence acceleration, top speed, and climbing capability, ensuring seamless performance across various road conditions.
2.Efficiency: High efficiency translates to less energy loss and extended range. A good electric drive system maintains high energy conversion efficiency under diverse conditions, enhancing vehicle economy by reducing energy wastage.
3.Noise: With increasing consumer demand for driving comfort, noise control is critical. Low-noise motors and transmission units create a quieter driving environment, enhancing overall driving pleasure.
4.Intelligence: Modern automotive trends emphasize intelligence. As a core component, the system's level of intelligence directly impacts overall vehicle smartness. Advanced control technologies enable the system to meet the growing demand for intelligent driving features.
5.Safety: As the vehicle's power source, system safety is paramount. A reliable system ensures stable operation under extreme conditions, guaranteeing passenger and vehicle safety.
Among the many suppliers in the market, VREMT, with its outstanding technological prowess and innovation, has become a trusted brand for Hybrid vehicle drivetrains. VREMT's independently developed 800V high-performance electric drive system sets new industry benchmarks in performance, intelligence, comfort, and safety.
The VREMT 800V electric drive system boasts a powerful 200kW output, delivering remarkable acceleration capability. This is achieved through Hair-pin flat wire winding technology, which increases slot fill factor by over 20%, resulting in higher power density and compact size.
Moreover, features like high rigidity design of rotating systems, application of third-generation carburized rare earth materials, and high-speed bearing matching enable the motor to achieve an astonishing speed of 16,500 rpm. The high reluctance dual-layer magnetic circuit design, combined with excellent heat dissipation capability of the flat wire motor, significantly enhances peak output to 343Nm.
Safety has always been an unchanging pursuit for VREMT. The electric propulsion system adheres to a design philosophy focused on system safety and is equipped with intelligent control strategies, ensuring a high level of safety and reliability. The application of AUTOSAR architecture and Modular Development (MBD) ensures the stability and scalability of the electric propulsion system. Additionally, VREMT's electric drive system is among the first in the industry to receive dual certifications from TÜV Rheinland for "Drive Control Robustness" and from China Automotive Technology and Research Center (CATARC) for "Power Safety Star," demonstrating its leading position in the field of new energy.
With the continuous expansion of the new energy vehicle market and increasing consumer demand for high-quality travel experiences, the importance of electric propulsion systems is becoming more pronounced. Looking ahead, VREMT is committed to driving technological innovation to deliver smarter, safer, and more efficient green travel experiences for users.
