BorgWarner Enhances Electrification Efforts with Great Wall Motor Collaboration

BorgWarner and Great Wall Motor Partnership

BorgWarner, a leader in advanced propulsion systems, is deepening its collaboration with Great Wall Motor in the electrified propulsion sector. This expansion marks a significant milestone as BorgWarner has secured two additional projects following the initial dual inverter programs announced earlier. With mass production anticipated to kick off in 2026, this collaboration is positioned to set new benchmarks in the automotive industry's shift towards electrification.

Strengthening Technical Expertise

According to Dr. Stefan Demmerle, Vice President of BorgWarner and head of PowerDrive Systems, this ongoing partnership speaks volumes about BorgWarner's technical prowess in the area of electrification and dual inverter technologies. BorgWarner's innovative solutions continue to earn the trust of Great Wall Motor, highlighting their commitment to enhancing their electrified vehicle portfolio.

The Technology Behind the Dual Inverter

BorgWarner's dual inverter technology showcases a highly integrated design, which allows for the control and functioning of two motors via a single controller. This streamlined approach not only results in improved packaging and installation flexibility but also capitalizes on BorgWarner's proprietary technology to pack various power modules into compact structures, thereby minimizing weight and production costs.

In this context, the power module with double-sided cooling stands out. It features the latest Viper power switch generation, which effectively lowers thermal resistance by as much as 50% versus conventional single-sided cooling methods, fundamentally enhancing power density.

Additionally, this technology has been designed to accommodate a variety of semiconductor dies within identically sized modules, ensuring they meet the increasingly stringent requirements set forth by the China light-duty vehicle test cycle (CLTC).

Another critical aspect of BorgWarner's dual inverter is its adaptive battery voltage regulation capability, which extends the motor's operational range while maintaining high efficiency, thus significantly optimizing the overall system performance.

Versatility Across Hybrid Applications

The dual inverter's platform-centered design allows it to be compatible with a broad spectrum of hybrid vehicle applications. Among the recently awarded projects, one involves a hybrid electric vehicle (HEV) dual inverter that integrates both a DC/DC converter and voltage boost module, while the other relates to a plug-in hybrid electric vehicle (PHEV) dual inverter that omits these components. This modular development approach empowers customers to accelerate their product iterations while significantly reducing both design and development costs.

BorgWarner has established a robust reputation over the past 130 years as a pioneer in mobility innovation, with a heightened emphasis on sustainability. The company’s efforts are not just aimed at making electrified vehicles more efficient but also at contributing to a cleaner and more secure future for all. As the automotive landscape continues to evolve, BorgWarner's advancements in dual inverter technology exemplify its commitment to driving forward the future of sustainable transportation.

Looking Ahead

The evolving landscape of electric mobility presents numerous challenges and opportunities, particularly in light of recent global shifts in environmental policy and consumer expectations. BorgWarner is poised not just to respond to these changes but to lead the charge in transforming the automotive industry into a greener, more sustainable future. As they take these significant steps, the collaboration with Great Wall Motor epitomizes their dedication to innovation and partnership in achieving these ambitious goals.

In summary, the extension of BorgWarner's partnership with Great Wall Motor is a forward-looking venture that reinforces the importance of collaboration in advancing electric vehicle technology—capable of defining the next wave of automotive innovation.
