New ultra-lightweight EV transmission concept presented at LCV 2017

August 10, 2017

Technical paper highlights potential for 30% savings through a whole system approach to mass reduction


Leamington Spa, UK, 10th August 2017 – Drive System Design (DSD), transmission and driveline engineering specialist, will present details of new EV transmission technologies at the Low Carbon Vehicle Event 2017 at Millbrook (September 6-7). The paper, Ultra-lightweight design of a single speed EV transmission, explores the potential gains of adopting a full system approach to transmission mass reduction for EV applications, including yield savings of more than 30% when compared to conventional transmission designs.


The paper, which has been authored and will be presented by DSD Head of Design Matt Hole, examines the savings that can be made through the use of alternative materials, and details the challenges that oppose widespread composite adoption in mainstream automotive. “The increased materials cost of utilising composites can be offset by savings made elsewhere in EV drivetrain design, making lightweighting a feasible solution for improving efficiency,” explains Hole. “Extended EV range, enhanced NVH and heightened durability can all be provided by thorough investigation of the potential of transmission mass reduction, as our paper details.”


Ultra-lightweight design of a single speed EV transmission also explores the practical use of structural thermoplastic composites, new processes for forming such materials and offers an objective assessment of using a full-system model to achieve weight saving at a system level.


A second paper, The future of the connected powertrain, will be presented by DSD’s Head of Electrified Powertrain, Simon Shepherd. He will offer a cost-effective monitoring system that provides a step-change in the understanding of individual transmission usage profiles by interrogating the data available through increased levels of vehicle connectivity
