Complete electric drive module supports small car hybridisation
14 September 2016
GKN Driveline has developed a complete electric drive system for plug-in hybrid vehicles, starting production in 2019 on a global platform.
Tighter integration of electric drivelines improves system efficiency and gives automakers more packaging and assembly options. The new module integrates a water-cooled electric motor and inverter with a single speed eAxle reduction gearbox. The system generates a maximum 65kW of power and can deliver up to 2,000Nm of torque to the rear wheels.
GKN Driveline Chief Executive Phil Swash said “a new generation of vehicles is making hybridisation integral to platform strategies. These complex drivelines require the higher levels of system integration that GKN eAxle electric drive modules deliver. By pioneering the development of these systems, GKN is positioned to help automakers turn electric propulsion into exciting new hybrid all-wheel drive experiences.”
The complete eDrive module measures just 300mm high and 325mm wide and weighs 54kg, making it around 20mm narrower and 2.5kg lighter than comparable systems. GKN’s system ensures that, despite significant differences in the acoustic signatures of the inverter, motor and gearbox, the overall system delivers a smooth, near silent electric driving experience.
Peter Moelgg, Chief Executive of GKN Driveline’s eDrive and AWD business, added “automakers increasingly want complete eDrive systems from suppliers, rather than sourcing the different elements from different companies. This is the first all-in-one eDrive system to replace external wiring with a bus bar and to eliminate unnecessary mechanical interfaces. The result is an eDrive system with higher power density that is simpler to install.”
