The ER60 Range-Extended Generator System by Dowway Vehicle is a high-efficiency, oil-cooled power generation unit engineered for extended-range electric vehicles (EREVs) that demand reliability, compact packaging, and superior performance. As a leading Chinese manufacturer specializing in EV drivetrain R&D and customization, Dowway Vehicle delivers more than a component—we provide end-to-end engineering partnership, from concept to mass production.
Built around a 6-layer flat-wound permanent magnet synchronous motor (PMSM), the ER60 achieves exceptional power density and thermal efficiency. It delivers 93 kW peak electrical power and 60 kW rated power across a wide operating voltage range (260V–470V), ensuring seamless compatibility with both 400V and transitional high-voltage architectures. With 200 Nm peak torque and 175 Nm rated torque at speeds up to 6,000 rpm, the system provides smooth, responsive power delivery ideal for passenger cars and light commercial EREV platforms.
Designed for harsh automotive environments, the ER60 features oil-cooled thermal management for stable operation under continuous load, plus dual protection ratings: IP67 for dust/water immersion resistance and IP6K9K for resilience against high-pressure, high-temperature steam cleaning—critical for underhood durability. Its EMC Class 3 compliance ensures minimal electromagnetic interference, enabling safe integration with sensitive vehicle electronics.
Measuring just 411 × 347 × 489 mm, the compact design allows flexible packaging in space-constrained chassis layouts without sacrificing performance.
At Dowway Vehicle, we empower global EV innovators through customization:
- Voltage/platform adaptation (400V/800V readiness)
- Mechanical interface & mounting optimization
- CAN communication protocol tuning
