BorgWarner Debuts First Integrated Electric Drive Module for EV Market

BorgWarner, which is a key player in clean and efficient technology solutions for combustion, hybrid and electric vehicles, will be shortly debuting its electric drive module (eDM) comprising an integrated eGearDrive transmission. The new transmission will make its appearance first in two pure electric vehicles that are being launched by a major Chinese automotive manufacturer. The company is expected to begin production of the vehicles in summer 2017.

Speaking about the new drive module, Dr. Stefan Demmerle, President and General Manager, BorgWarner PowerDrive Systems said that the company’s new eDM will effectively combine BorgWarner’s know-how in eGearDrive transmissions, which it first launched in 2009, with its new  expertise in electric motor technology from the former REMY business. The brand’s first application of the integrated drive module would be manufactured on a local basis in China.”

BorgWarner’s eDM can be used to provide either primary or secondary propulsion for pure electric or P4-type hybrid vehicles. The integrated design of the electric motor and transmission will allow manufacturers to make weight, cost and space savings. Installation of the unit will also be easier as both the electric motor and the transmission are accommodated in one housing.

Depending on the vehicle manufacturer’s desired propulsion characteristics, it is possible to optimize the performance of the unit with various available gear ratios to come up with a completely customized  solution. The unit is notable for its use of patented high voltage hairpin (HVH) technology and optional power electronics, while BorgWarner’s HVH 250 electric motor is highly efficient as it exhibits 95 percent efficiency. The electric drive module extends the battery-powered driving range with its high-efficiency gear train and compact, low-weight design and this further reduces the required capacity for the battery. Another feature that is available is an electronically actuated park lock system.

BorgWarner has a wide range of products that also comprises many other innovative products for electric and hybrid vehicles like its cabin heaters, auxiliary thermal coolant pumps and the eBooster^® electrically driven compressor, cabin heaters and auxiliary thermal coolant pumps.
