250 kW / 290 kW E-Axle for Trucks
Our 250 kW / 290 kW e-axle for trucks integrates a high-efficiency PMSM, transmission, and axle into a compact unit. By leveraging the gear ratio of the integrated transmission, the system delivers high torque output even with a relatively smaller motor.
The wheel-end output torque can reach up to 40,000 N.m, making it ideal for 6×4 and 4×2 truck tractors, semi-trailers, water tankers, garbage trucks, dump trucks, and other heavy-duty transport or municipal vehicles. This e-axle system is already in mass production and has been deployed in batch applications on electric semi-trailers.

Solution Features
- IP67 water and dust protection, along with rigorous high/low temperature and vibration testing, ensures outstanding system reliability.
- One-piece axle housing provides high load-bearing capacity while maintaining ease of maintenance.
- Driveshaft eliminated, allowing more space in the chassis for flexible and efficient battery pack installation.
- Integrated design results in lighter weight, higher efficiency, and better energy savings.
Technology Highlights
Our e-axle for trucks features a 2-speed AMT. It enables active speed synchronization between the motor and the transmission input shaft, allowing for rapid and smooth gear shifts. By combining gear profile modification with in-depth analysis of casing and shaft tooth deformation, the system achieves optimal meshing conditions, minimizing transmission error and reducing efficiency loss.
- Shorter gear shifting time
- Higher transmission efficiency
- Lower operating noise
How We Ensure the Reliability of Our E-Axle for Trucks
Our e-axle system undergoes a rigorous multi-level validation process to guarantee long-term performance, safety, and durability under real-world operating conditions.
Component-Level Testing
Over 50 tests are conducted on individual components to verify structural integrity, strength, and consistency. These include:
- Vibration
- Salt spray
- Tensile
- Torsion
- Hardness
- Full-dimension inspections
Subsystem-Level Testing
More than 90 tests are performed across all core subsystems – including the shifting mechanism, gearbox, motor, high/low voltage controllers, wiring harnesses, and software. These tests fall into six major categories:
- Module validation
- Functional testing
- Performance testing
- Durability testing
- Reliability testing
- Environmental resistance
System-Level Testing
Over 50 tests are carried out at the system level using specialized test benches and real-vehicle road trials, including:
- High and low temperature cycling
- Thermal shock testing
- Salt spray and corrosion resistance
- Waterproof and dustproof validation
- Vibration and noise testing
- System integration and special-condition simulation
