The EP220 Three-in-One Electric Drive System by Dowway Vehicle is a high-performance, integrated e-axle solution engineered for next-generation electric passenger cars, SUVs, and performance EVs. Combining motor, gearbox, and inverter into a single compact unit, the EP220 delivers exceptional power density, efficiency, and functional safety—backed by Dowway Vehicle’s full in-house R&D and customization capabilities as a trusted Chinese EV drivetrain manufacturer.
At its core lies an 8-layer flat-wound permanent magnet synchronous motor (PMSM), enabling ultra-high efficiency and thermal stability. The system operates across a wide 420V–850V voltage range, making it fully compatible with modern 800V high-voltage architectures for ultra-fast charging and reduced energy loss. It delivers 220 kW peak power and 80 kW rated power, with 420 Nm motor torque amplified to an impressive 4,800 Nm wheel-end peak torque through a 12.01:1 fixed gear ratio—ideal for rapid acceleration and demanding driving conditions.
Designed for extreme reliability, the EP220 features oil-cooled thermal management for sustained high-load operation, IP67 ingress protection, and ASIL D functional safety certification—the highest level in automotive safety standards. Its Class 3 EMC compliance ensures seamless coexistence with advanced ADAS and infotainment systems.
With compact dimensions of just 454 × 485 × 325 mm, the EP220 enables flexible packaging in space-constrained vehicle platforms without compromising performance.
