BorgWarner is to launch its electric drive module (eDM) with integrated eGearDrive transmission in two pure electric vehicles from an unnamed Chinese automaker, with production expected to begin in summer, 2017.
BorgWarner’s new eDM combines its know-how in eGearDrive transmissions, first launched in 2009, with background in electric motor technology from the former REMY business.
The eDM provides primary or secondary propulsion for pure electric or P4-type hybrid vehicles, with BorgWarner maintaining integrated design of the electric motor and transmission enables weight, cost and space savings.
Both functions are combined into one housing and based on the vehicle manufacturer’s desired propulsion characteristics, performance is optimised with various available gear ratios. Featuring high voltage hairpin (HVH) technology and optional power electronics, BorgWarner’s HVH 250 electric motor delivers performance with more than 95% efficiency.
Through its gear train and low-weight design, the eGearDrive transmission contributes to extended battery-powered driving range. An electronically actuated park lock system is also available.
BorgWarner’s product portfolio also includes other technologies for hybrid and electric vehicles, such as the eBooster electrically driven compressor, cabin heaters and auxiliary thermal coolant pumps.
