Magna to Launch Industry-First Award with Modular eDecoupling Unit for BEVs

A bolt-on stand-alone solution for BEVs, Magna’s electro-magnetic eDecoupling is a robust, field proven product technology that is integrated as a complete module. The eDecoupling is an electromechanical device that disconnects the e-motor from the driveshaft in electric vehicles when propulsion power is not needed, reducing energy consumption and increasing efficiency. It contributes to increased electric driving range of up to nine percent, a significant benefit for all EVs. This is achieved by reducing drag torque losses of the e-motor and gearbox while its eDecoupling controls software smoothly operates all shifting sequences.

“Our new and innovative modular eDecoupling unit aligns perfectly with OEMs’ in-house manufacturing strategies for electric drive systems,” said Diba Ilunga, President Magna Powertrain. “Due to the compact design of the unit, we’ve successfully minimized added package space and weight in both axial and radial direction, which has helped ensure that it can be scalable for use across electric and hybrid vehicles from B segment up to SUVs and LCVs.”

The modular eDecoupling unit presents various features for customers, including: superior NVH behaviour thanks to seamless integration via powertrain controls; compact packaging; and a fast activation time of less than 100 milliseconds.

Production of the new eDecoupling unit will be at Magna’s powertrain facility in Lannach, Austria.

Magna has developed a complete family of decoupling units that will be going into mass production in BEV secondary eDrive applications in the near future.
