To support the transition to cleaner and more efficient vehicles, BorgWarner in Auburn Hills today announced it is releasing its P2 module for hybrid electric vehicles (HEVs) to global customers. Available as both on- and off-axis configurations, the company’s technology facilitates fast-to-market hybridization by enabling pure electric driving as well as hybrid functionalities such as stop/start, regenerative braking, and supplemental electric propulsion.
Placed between the internal combustion engine and the transmission, BorgWarner’s P2 modules are capable of decoupling the engine for limited pure electric driving. They enable both mild hybrid architectures with 48-volt power supplies as well as conventional high-voltage applications.
Moreover, BorgWarner’s hybrid solutions combine an efficient electric traction motor, power electronics, an engine disconnect clutch and clutch control module as well as a dual mass flywheel in one compact module that needs minimal axial space.
By uniting all required components in a compact package, the P2 Module can be implemented in existing drivetrains, enabling capital utilization and hybrid volume flexibility for automakers. Both configurations of the company’s P2 module provide significant CO2 emission reductions with low added costs compared to other hybrid architectures.
“With our innovative and highly adaptable P2 modules, we offer tailor-made solutions that meet our customers’ specific requirements. In order to provide an optimal propulsion system solution, we regularly join forces with global OEMs — today we are pleased to announce a comprehensive development contract with a Chinese automaker for our on-axis design,” says James R. Verrier, president and CEO of BorgWarner.
“Trends like autonomous driving, connected cars, ride sharing, and efficiency are driving change in the automotive industry, and P2 hybrids are receiving a great deal of attention. As a leading supplier for clean and efficient technologies for combustion, hybrid, and electric vehicles, we are uniquely positioned to enable these trends and support automakers around the globe as they move toward a clean, energy-efficient future.”
To address the highly varied application spectrum for hybridization, BorgWarner developed two design variants: on-axis and off-axis. In the former, the electric motor is located directly on the main axis enabling easy integration and a compact overall package. This configuration allows several clutch options, offers high power density and increases fuel efficiency as well as performance.
The off-axis configuration places the electric motor parallel to the main axis for an even more compact axial package minimizing changes necessary to implement with existing engines and transmissions. Torque is transferred via a highly efficient and durable chain.
The design offers compatibility with manual, automatic, and dual-clutch transmissions and addresses the tight packaging of modern drivetrains. In addition, it allows for the use of different gear ratios and the integration of further chain-driven components.
