EV Speed

Subtitle

UK-based Drive System Design is developing a new EV powertrain based on an alternate approach to powershifting (no torque interrupt) achieved by separating the existing functions of a synchronizer. The integrated design of an axial flux YASA motor (earlier post) with the multi-speed transmission contributes to simplification of the motor cooling system, electrical architecture and powertrain control system.


The MSYS system can mean a 10-15% improvement in the range of electric vehicles, the company says. (Earlier post.) The company was recently showcased at the Cleantech Innovate 2014 event by the UK’s LowCVP organization (Low Carbon Vehicle Partnership), along with 7 other companies. DSD was the winner of a LowCVP commendation as the most impressive of the road transport-focused entries.


(DSD is participating in the Evoque_e research program (earlier post) to develop new modular hybrid, plug-in hybrid, and battery-electric vehicle (BEV) technology. The pure electric research vehicle will the MSYS multi-speed traction system developed.)
