The EX170 is a next-generation seven-in-one integrated electric drive system designed for mid-to-high-end electric vehicles, including passenger cars, SUVs, and light commercial vehicles. It achieves unprecedented integration by combining the permanent magnet synchronous motor (PMSM), inverter, planetary gear reducer, on-board charger (OBC), DC-DC converter (DCDC), DC-AC converter (DCAC), and power distribution unit (PDU) into a single compact module. This eliminates the need for multiple separate components, reducing weight, volume, and wiring complexity while improving thermal management and system efficiency.
At its core lies a high-efficiency PMSM delivering 200kW peak power and 290Nm peak torque, with a rated output of 120kW and 150Nm. The motor operates at a maximum speed of 22,000rpm, enabling high-speed performance and rapid acceleration. The planetary gearbox provides a reduction ratio of 13.561, optimizing torque delivery across the operating range. The entire system is cooled via an oil-cooling loop, ensuring stable performance under continuous high-load operation and preventing thermal throttling during long drives or hill climbs.
The on-board charger (OBC) supports up to 6.6kW AC charging, allowing convenient home or public charging without external equipment. The DC-DC converter (DCDC) provides 2.5kW output for low-voltage systems (e.g., 12V battery), while the DC-AC converter (DCAC) delivers 3.5kW for auxiliary loads such as air conditioning or onboard appliances. The PDU manages power distribution to all subsystems, ensuring safe and efficient energy flow.
Engineered for reliability: operates reliably from -40°C to +125°C, withstanding vibrations up to 5g RMS and shock loads of 50G. The IP67-rated housing protects against dust ingress and temporary immersion in water. Manufactured under IATF 16949 with ISO 26262 ASIL-B functional safety compliance. All units undergo 1,000-hour accelerated life testing, thermal cycling validation, and full-load endurance tests. Supports white-label customization with rapid NPI cycles (14 days) and regional compliance packages (EU Type Approval, China CCC, U.S. DOT).
