BorgWarner wins dual inverter supply deal from major Chinese OEM for hybrid vehicles, ETAuto

BorgWarner has secured a fresh contract to supply its advanced dual inverter systems to a leading Chinese original equipment manufacturer (OEM) for their upcoming range of hybrid vehicles. This deal marks a continuation of the two companies’ collaboration that began in 2021 and is set to enter mass production by the end of 2025.

“We are pleased to once again win dual inverter business from this important customer. This milestone signifies a new phase of collaboration in the new energy vehicle sector,” said Dr. Stefan Demmerle, Vice President of BorgWarner Inc. and President and General Manager, PowerDrive Systems.

The dual inverter system from BorgWarner enables synchronous control of two electric motors through a single controller, significantly enhancing packaging flexibility and installation convenience. Leveraging proprietary packaging technology, the system integrates multiple power modules into a compact design, helping reduce overall vehicle weight and cost—key considerations in hybrid vehicle development.

A standout feature of the technology is its advanced power module design, which offers up to 50 per cent lower thermal resistance compared to single-sided cooling. This translates into a higher power density, meeting the growing demands of China’s stringent CLTC (China Light-Duty Vehicle Test Cycle) efficiency standards. The system’s adaptive battery voltage regulation also broadens the motor’s constant power and efficiency ranges, ultimately improving overall system performance.

BorgWarner continues to evolve its dual inverter platform with ongoing improvements in system architecture and hardware design. Its third-generation model integrates a high-performance single chip for both DC-DC conversion and dual motor control, with the ability to add high-voltage auxiliary interfaces as per customer needs. Meanwhile, the upcoming fourth-generation variant includes a built-in boost converter and supports optional DC-DC modules, offering greater flexibility for next-generation hybrid vehicle platforms.
