Hypermotive are delighted to announce that they been awarded Niche Vehicle Network (NVN) grant funding for a consortium-based project to develop a concept low-emission, highly efficient range extender for electric vehicles.  Hypermotive, lead partner for the consortium, alongside project partners AIE ( and Sunamp (, were present at the Cenex LCV2017 event where the award was announced.  Engineering Director, Jeremy Bowman, and Programme Manager, Liz Harber, received the grant from Rob Anderson of the Niche Vehicle Network alongside Bob Austin of Sunamp and Thomas Lee of AIE.


The project will use simulation and modelling alongside practical testing to quantify the effect of combining AIEs innovate Wankel engine with a DC generator, assessing the requirement for a DCDC converter over controlling the charging voltage via engine throttle management. Furthermore, through integration of Sunamp’s ground-breaking heat battery technology into the system, the project will qualify the effects of thermal energy storage on improving engine start-up efficiency and overall system efficiency by reducing the electrical load required for cabin heating.


This project draws on a number of Hypermotive’s key engineering capabilities and experience including powertrain simulation and modelling, and electrical powertrain integration.


Jeremy Bowman, Engineering Director Hypermotive ‘’This grant will help support our exciting collaboration with AIE and Sunamp and kick-start the development of a highly fuel and thermally efficient engine for the next generation of range extended BEVs.’’

Our partners:


AIE specialises in the development of Wankel rotary engines for automotive powertrains and hybrid-electric range extenders. With a combined experience of over 80 years in research & development, AIE manages entire project lifecycles from concept through to production. AIE uses cutting-edge software and a clean-sheet design approach to make engines that deliver high power-to-weight ratio and low vibration with a very small form factor and few moving parts. The rotary engine forms a lightweight package ideal for series hybrid low carbon vehicles when integrated with electric drive systems or as a primary power unit in a high performance sports powertrain solution.


Sunamp develops, manufactures and sells compact, highly efficient advanced thermal storage technology called ‘Heat Batteries’ that can be used to store heat for a number of applications. Sunamp HBs are based on phase change materials that have high energy and power densities.  Our HBs help reduce emissions and improve air quality and address vehicle thermal management challenges such as engine and cabin warm up, catalytic converter temperature fluctuation and battery thermal conditioning and HVAC systems.


The Niche Vehicle Network (NVN) is a free to join networking and support organisation focused on enabling UK low volume vehicle manufacturers and design and engineering companies to research and develop innovative low carbon vehicle technologies.  The Network is funded by the Office for Low Emission Vehicles, Innovate UK, the Advanced Propulsion Centre and the Department for Business, Energy and Industrial Strategy.
