The Five-in-One Integrated Powertrain System is a next-generation hybrid drivetrain solution designed for plug-in hybrid electric vehicles (PHEVs), extended-range electric vehicles (EREVs), and high-performance hybrid cars. It achieves unprecedented integration by combining the P3 electric drive system and P1 generator system into a single compact module—reducing weight, volume, and wiring complexity while improving thermal management and system efficiency.
The P3 electric drive system delivers 100kW rated power and 165kW peak power, with a wheel-end peak torque of 3800Nm and a maximum wheel-end speed of 1500rpm. This enables strong acceleration and hill-climbing performance in pure electric mode. The P1 generator system provides 60kW rated power and 105kW peak power, with a peak torque of 230Nm and a system maximum speed of 6000rpm, enabling efficient regenerative braking and engine-assisted charging during hybrid operation.
Both systems operate on a 380V voltage platform, with a working voltage range of 200–500V DC, ensuring compatibility with various battery configurations and supporting both low-speed urban driving and high-speed highway cruising. The integrated design allows seamless transition between electric-only, hybrid, and regenerative
modes, optimizing fuel economy and reducing emissions.
The system features advanced control algorithms such as field-oriented control (FOC) and vector control, enabling precise torque regulation, smooth low-speed operation, and reduced cogging effects. The oil-cooling system ensures stable performance under continuous high-load operation, with optimized flow channels that dissipate heat efficiently even during prolonged high-speed driving or repeated hard accelerations.
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, making it suitable for use in wet or dusty environments. The ASIL C functional safety rating ensures compliance with ISO 26262 standards for automotive applications, providing robust fault detection and response mechanisms. The EMC Class 3 certification guarantees electromagnetic compatibility with other vehicle systems, minimizing interference.
