BorgWarner Inc. (NYSE: BWA) has secured a new contract to supply advanced dual inverters to a leading Chinese original equipment manufacturer (OEM) for its hybrid vehicles. This deal marks an extension of the companies’ partnership, building on their earlier collaboration in 2021. The mass production of the dual inverters is set to begin by the end of 2025, further solidifying BorgWarner’s position as a key player in the electrification of the automotive industry, particularly in China’s rapidly expanding new energy vehicle (NEV) market.
“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 and President and General Manager of PowerDrive Systems. Demmerle highlighted the company’s ongoing commitment to delivering high-quality and innovative electrification solutions to its customers in the NEV space, a segment undergoing significant growth due to China’s push toward sustainability and cleaner transportation solutions.
BorgWarner’s dual inverter technology is designed to enable the synchronous control of two electric motors with a single controller, offering enhanced flexibility in packaging and ease of installation. The inverter’s compact design integrates power modules in a way that reduces both weight and cost, making it a highly efficient solution for hybrid vehicle platforms. This configuration allows for the packaging of different types of semiconductor dies within the same module size, ensuring compliance with the stringent China light-duty vehicle test cycle (CLTC) efficiency standards.
A key advantage of BorgWarner’s dual inverter is its advanced power module design, which reduces thermal resistance by up to 50% compared to traditional single-sided cooling systems. This reduction significantly improves power density and system efficiency, helping to extend the operational lifespan of hybrid vehicles while enhancing their performance. Additionally, the adaptive battery voltage regulation feature increases the motor’s constant power and high-efficiency operating ranges, contributing to a more sustainable and reliable powertrain.
BorgWarner’s technology is continuously evolving, with a third-generation production model already in development. The new model integrates a high-performance single chip that can handle both DC-DC conversion and dual motor control simultaneously. It can also be configured with high-voltage auxiliary interfaces tailored to customer-specific needs. BorgWarner is also working on a fourth-generation model, which will feature a boost converter, dual inverters, and an optional DC-DC module, offering greater flexibility and functionality for a wider range of hybrid vehicle platforms.
