BorgWarner has secured contracts to supply XPeng, a Chinese smart EV manufacturer, with its advanced oil-cooled 800V e-motor systems for two upcoming SUV models.
These e-motors are based on BorgWarner’s high-voltage hairpin (HVH) technology and are designed to provide high power and torque density and improved efficiency and durability.
BorgWarner’s oil-cooled solutions have been developed to meet the demand for enhanced performance in high-power motors. The technology uses gearbox oil for motor cooling to improve heat transfer and thermal management efficiency, and direct rotor oil cooling extracts heat from the electric motor core, enabling higher torque and density.
The HVH220 e-motor – operating within an 800V propulsion system– has a stator outer diameter of 220mm and integrates a permanent magnet rotor and proprietary stator insulation enhancements. BorgWarner says the e-motor is capable of generating up to 300kW of power and reaching a maximum speed of 18,000rpm, achieving peak efficiencies that exceed 97%.
“We are thrilled to expand our e-motor business with XPeng and build upon our years-long partnership with them,” said Dr Stefan Demmerle, president and general manager of BorgWarner PowerDrive Systems. “As we continuously evolve our HVH technology, we are dedicated to delivering maximum efficiency for our customer’s two future SUV models.”
Production of the e-motor systems is set to begin next year.
