BorgWarner, a global manufacturer of electrified propulsion and powertrain systems, has expanded its collaboration with automaker Great Wall Motor in the field of electrified propulsion. Building on two previously announced dual-inverter programs, the company has secured two additional projects with mass production scheduled for 2026.
The dual-inverter system developed by BorgWarner is designed to control and drive two electric motors simultaneously through a single controller.
This integrated design improves packaging flexibility, reduces overall system weight, and simplifies installation within hybrid and electric vehicle platforms.
The power module incorporates a double-sided cooling design that lowers thermal resistance by up to 50% compared to conventional single-sided cooling systems. This improvement enhances power density and thermal performance, which are critical factors in meeting modern efficiency and durability standards, such as China’s light-duty vehicle test cycle (CLTC).
The inverter architecture allows for different semiconductor die configurations within the same package size, providing flexibility for various vehicle voltage levels and performance requirements. Adaptive battery voltage regulation further extends the motor’s constant power and high-efficiency operating range, improving overall system efficiency.
The platform-based design also supports multiple hybrid vehicle configurations. In the newly awarded projects, the hybrid electric vehicle (HEV) version integrates a dc/dc converter and includes an optional voltage boost module, while the plug-in hybrid (PHEV) version omits both modules for a more compact layout.
This modular approach enables faster adaptation to different vehicle architectures and reduces development complexity.
By consolidating inverter and power conversion functions, BorgWarner’s dual inverter system supports the growing demand for compact, efficient, and flexible power electronics across a range of hybrid and electric vehicle applications.
