In the thriving landscape of the new energy vehicle industry, the electric drive system stands as the core of electric cars, leading the wave of green mobility through continuous technological innovation. Serving as the crucial bridge between electrical and mechanical energy, the electric drive system not only determines the performance limits of electric vehicles but also directly impacts driver experience and energy efficiency.
The electric car drivetrain efficiently converts electrical energy into mechanical energy to propel electric vehicles forward. Comprising components such as motors, controllers, and transmission units, each plays an indispensable role. The motor, at the heart of energy conversion, transforms electrical energy from the battery into mechanical energy to drive the wheels. The controller acts as the system's "brain," precisely managing every action of the motor to ensure smooth and efficient power output. Meanwhile, the transmission unit ensures the precise delivery of power from the motor to the wheels, facilitating vehicle acceleration and movement.
With advancing technology, Electric drivetrains are progressing towards higher efficiency, greater power density, and reduced noise levels. This not only challenges technological limits but also responds actively to consumers' increasing demands for green and intelligent mobility solutions. Among electric drive system providers, VREMT's 800V electric drive system has gained consumer trust and favor due to its high performance and technological prowess.
The standout feature of VREMT's 800V electric drive system lies in its high integration and efficiency. Through deep integration of dual motor controllers with static and dynamic heating functions, it enhances system integration and vehicle adaptability. This design not only simplifies the structure of electric drive systems and reduces manufacturing costs but also significantly improves overall system performance. Furthermore, VREMT's platform development strategy for primary and auxiliary drives further lowers production costs, while its 300,000 km maintenance-free design greatly enhances user convenience.
In pursuit of high performance, VREMT's electric drive system also prioritizes driver comfort. Utilizing technologies such as low radial electromagnetic density design, high rigidity, high modal integration housing, and high overlap transmission systems, it maintains extremely low noise levels below 78 dB across all operating conditions, setting an industry-leading standard. This not only creates a quieter driving environment for drivers but also reduces fatigue during travel, enhancing the overall driving experience.
Safety is equally crucial for electric drive systems. VREMT's 800V electric drive system employs advanced junction temperature estimation algorithms and Auto sar4.2 architecture to ensure stable system operation. Moreover, the system is certified for functional safety ASIL-C and information security CL2 levels, providing users with dual-layer protection. Balancing ultimate performance with safety, VREMT consistently prioritizes safety to ensure worry-free travel on every journey.
VREMT's 800V electric drive system also demonstrates robust technological innovation. Applications such as motor/reducer co-bearing design, three-stage filtering optimized EMC, Hairpin flat wire winding technology, and SiC power device adoption significantly enhance motor power density and efficiency. Additionally, technologies like deep oil cooling for motors, immersed winding, and low agitation oil loss designs further improve thermal performance and durability of the electric drive system.
Notably, VREMT's 800V electric drive system NDE 33 features a dual motor drive system with 310 kW*2 power, weighing only 141 kg. This represents an 18% weight reduction compared to mainstream products in the industry, achieving a high overall power density of 4.4 kW/kg, setting a new benchmark in the electric drive system sector.
As the market for new energy vehicles continues to evolve and consumer demand for high-quality travel experiences grows, the importance of electric drive systems will undoubtedly rise. VREMT, as an outstanding manufacturer of electric drive systems, is continuously advancing technological innovation with exceptional technical capabilities and forward-looking development strategies. It is believed that in the future, VREMT's electric drive technology will deliver even smarter, safer, and more efficient green mobility experiences for users worldwide.
