At the LCV 2016 event in the UK last week, Delta Motorsport unveiled a new low-cost micro-turbine applied as a range-extended in an electric car. The company developed the E-4 Coupe extended-range electric electric vehicle in a £3.1-million (US$4-million) collaborative R&D project. The Office for Low Emission Vehicles (OLEV) and Innovate UK co-funded the project.
The new system, dubbed MiTRE (Micro Turbine Range Extender), is specifically designed for use as a range extender for electric vehicles. Delta has produced two complete MiTRE prototype systems with 17 kW power output; one is fitted into the E-4 Coupe for further development.
The project was a collaboration between Delta Motorsport, Productiv, Hieta Technologies, the University of Bath, Schaeffler and Equipmake.
The device features small, lightweight turbo-machinery attached to an electric generator. This keeps the battery pack charged up or at least slows the power drain.
The MiTRE project sprang from Delta’s early work on electric vehicles in 2008-10, and it’s great to see the results of our efforts and those of our partners in the program. We now have a huge amount of interest in the system from automotive OEMs and Tier 1s, because we’ve focused from the start of the project on keeping the system small, light and inexpensive. Further developments in progress now will also reduce emissions (including NOx) to extremely low levels.—Delta Motorsport Engineering Director Nick Carpenter
