BorgWarner has initiated the production of eMotor rotor and stator components for XPeng Motors, a prominent Chinese Smart Electric Vehicle (EV) manufacturer. These components will be utilized in XPeng's X9 MPV and upcoming electric B-class sedan, with production slated to commence in the third quarter of 2024. The high voltage hairpin (HVH) 220 eMotor, developed by BorgWarner, is designed to offer high power and torque density, along with increased efficiency at a competitive cost, while ensuring exceptional durability.
Dr. Stefan Demmerle, President and General Manager of BorgWarner PowerDrive Systems, expressed enthusiasm about supplying components to XPeng Motors, a leading Original Equipment Manufacturer (OEM) in the electric vehicle industry. Demmerle highlighted BorgWarner's extensive product expertise and its role in supporting XPeng's advancements in electric drive technology.
The HVH220 eMotor boasts an operating range of up to 800V and utilizes BorgWarner's patented high voltage hairpin winding technology. With a stator outer diameter of 220 mm, the motor incorporates permanent magnet rotor and proprietary stator insulation enhancement technologies, enhancing durability and reliability. The HVH220 can deliver power up to 300kW with a maximum working speed of 18,000 rpm, achieving peak efficiencies exceeding 97%.
To address the performance requirements of higher-powered motors, BorgWarner has developed oil-cooled solutions. These solutions utilize gearbox oil to cool the motor, enhancing heat transfer and total heat rejection of the system. Additionally, direct rotor oil cooling facilitates heat extraction from the electric motor core, enabling higher torque and power density.
The collaboration between BorgWarner and XPeng Motors underscores the ongoing efforts to advance electric drive technology and bolster the electric vehicle industry.
