BorgWarner to supply highly-integrated, compact P2 drive module and electro-hydraulic control unit for ChangAn’s upcoming hybrid transmission

BorgWarner has announced that it has entered into an agreement with Chinese OEM ChangAn Automobile, to supply triple-clutch P2 drive module and electro-hydraulic control unit for latter’s new-generation hybrid transmission. BorgWarner expects to begin mass production of its P2 modules on the new ChangAn transmission model in 2020.

BorgWarner’s P2 drive module is highly integrated, and together with the electro-hydraulic control unit offers improved fuel economy and emissions. The scalable, modular design covers various levels of torque, and is available with an optional E-motor, in addition to being compatible with high-voltage PHEV, high-voltage HEV and 48V systems. BorgWarner said the compact, lightweight S-wind motor offers high torque density, especially suitable for P2 hybrids that are expected to become the mainstream of hybrid architectures.

The introduction of State VI emission standard in China, which will be officially implemented in 2020, along with stricter fuel consumption regulations has brought challenges for OEMs in the country. Traditional combustion technologies are unable to meet stricter emission requirements, leading to the focus towards the development of hybrid technologies for the automotive industry, the company noted.

BorgWarner’s on-axis P2 drive module delivers cost-effective hybridisation by being compatible with existing vehicle platforms, by placing the electric motor directly between the internal combustion engine and the transmission. It said the P2 solution offers the possibility of integrating up to three clutches, including a disconnecting clutch. This allows the system to decouple from the engine for pure electric driving, enabling customers to achieve their individual fuel-efficiency and performance goals, the company added. In addition, BorgWarner can supply the electrohydraulic controls for actuating the wet clutches, giving customers the option to choose individual components or a complete system.

BorgWarner said that its P2 drive module is also available in an off-axis configuration. This design places the electric motor parallel to the main axis and connects the system via one of the company’s durable chain technologies, ensuring maximum torque transfer. The company’s P2 drive modules give OEMs the flexibility to place the electric motor where they have space in existing architectures. In addition, by using BorgWarner’s S-wind wire-forming process to create the motor, the P2 drive module produces high power and torque densities in an extremely compact package.

Innovative manufacturing process allows BorgWarner to produce smaller, more powerful high-voltage electric motors on a mass scale and will help drive growth in the hybrid and electric vehicle market. Furthermore, unlike other off-axis P2 solutions that use a belt to attach the system, BorgWarner’s module delivers top performance from connecting the P2 via quiet and durable chain drive technologies. The solution further offers stop/start, regenerative braking and supplemental electric propulsion, and is available for 48-volt and high-voltage hybrid systems.

Dr Volker Weng, President and General Manager, BorgWarner Transmission Systems, said being awarded these contracts reinforces the company’s position in the global HEV market. It also validates the system integration ability of BorgWarner’s modules, he added. Dr Weng further said that BorgWarner is committed to providing high-quality products and services to customers, and developing next-generation transmission technologies for more sustainable mobility.
