BorgWarner has secured a fresh contract to supply its dual inverter systems to a major automotive manufacturer in China for use in hybrid vehicle models. This new agreement follows a similar collaboration initiated in 2021 and marks the latest step in the growing partnership between the two companies. Production under the new deal is expected to begin by the end of 2025.
“We’re proud to continue building on our relationship with this key customer,” said Dr Stefan Demmerle, Vice President of BorgWarner Inc and head of its PowerDrive Systems division. “This agreement reflects a deepening commitment to advancing electrified mobility in China’s fast-moving new energy vehicle sector.”
BorgWarner’s dual inverter enables simultaneous control of two electric motors through a single controller, offering more compact packaging and greater flexibility during installation. The company’s design integrates multiple power modules into one unit, reducing both the overall size and weight of the system—benefits that contribute to lower vehicle manufacturing costs.
The inverter’s power module features a dual-sided cooling system that cuts thermal resistance by up to 50% compared to conventional designs, significantly boosting power density. The system also supports mixed semiconductor configurations within a standardized module size, helping automakers meet China’s strict light-duty vehicle efficiency regulations. A key feature of the technology is its adaptive voltage control, which broadens the motor’s constant power range and enhances overall energy efficiency.
BorgWarner continues to enhance its inverter lineup through ongoing system upgrades. The third-generation version features a high-performance chip that manages both dual motor control and DC-DC conversion. It also offers flexible auxiliary high-voltage interfaces to meet various vehicle platform requirements.
The fourth-generation model goes a step further by incorporating a boost converter along with dual inverters. An optional DC-DC converter module can also be included, allowing the system to adapt to a wider range of hybrid configurations. This latest project reinforces BorgWarner’s role as a key supplier in the global shift toward electrified vehicle powertrains, particularly within one of the world’s most competitive automotive markets.
With a legacy spanning over 130 years, BorgWarner continues to lead the development of advanced mobility technologies. The company is committed to delivering sustainable solutions that contribute to a cleaner, safer, and more efficient future.
