BorgWarner has announced two additional dual inverter programs with Great Wall Motor, strengthening an existing partnership in electrified propulsion systems. Mass production for the new projects is scheduled to begin in 2026.
The expansion builds upon two previously announced dual inverter programs between the companies. The collaboration centers on BorgWarner's advanced dual inverter technology, which enables simultaneous control and drive of two motors through a single controller.
Dr Stefan Demmerle, Vice President of BorgWarner Inc. and President and General Manager of PowerDrive Systems, said the partnership extension reflects recognition of the company's products and technologies, as well as its commitment to supporting customer electrification strategies.
The dual inverter technology features a highly integrated design that enhances packaging flexibility and installation convenience. BorgWarner's proprietary packaging technology allows different power modules to be configured within a compact structure, reducing both weight and cost.
A key technical feature is the power module's double-sided cooling design, which incorporates the latest generation of Viper power switches. This design reduces thermal resistance by up to 50 percent compared to single-sided cooling, significantly improving power density.
The platform-based design enables compatibility across various hybrid vehicle applications. Among the newly awarded projects, the hybrid electric vehicle dual inverter integrates a DC/DC converter with an optional voltage boost module, while the plug-in hybrid electric vehicle version eliminates both components. This modular approach is designed to accelerate product development and reduce design costs.
The technology also addresses China's increasingly stringent light-duty vehicle test cycle efficiency standards through adaptive battery voltage regulation, which extends the motor's constant power and high-efficiency operating ranges.
BorgWarner, which has operated for more than 130 years, focuses on sustainable mobility innovation.
