Applying novel low cost electrical machine and power electronic topologies to Range Extenders

Lead Participant: Lyra Electronics Limited

Abstract

Currently, battery technology represents the major bottleneck to widespread uptake of electric vehicles. Range Extender devices, which combine an internal combustion engine with a generator, provide a vital medium-term solution to reducing tailpipe emissions and facilitate the transition to an electric vehicle infrastructure. There is an industry-wide trend towards faster motor speed, driven by targets from the US Department of Energy and the wider electric vehicle market. These high-speed motors typically perform poorly in the low-speed usage typical of range extenders and a bespoke solution is therefore required in order to reduce vehicle cost as far as possible. This project aims to lower the cost of Range Extenders by using novel, polymer-bonded Halbach generator construction, together with automation of the design optimisation process using a software-driven approach.
