Addressing range anxiety issues associated with low Carbon electric vehicles.

Globally, there is a rapidly growing market for low carbon vehicle technologies to address legislative requirements for reduced CO2 emissions.  Although there has been an international movement towards the use of electric vehicles (EV), there is a major issue with range anxiety.

Project Background

The ‘PURE’ project is developing and combining highly innovative technologies to produce a low cost, light weight, compact, low CO2, highly efficient auxiliary power unit (APU) for electric vehicles. The APU will address range anxiety issues associated with battery powered electric vehicles.   This issue alone has created barriers for the customer in terms of purchasing full electric vehicles, which combined with pricing issues, presents a major obstacle to market growth. Delivering a solution bespoke to the automotive industry, the APU will initially be configured to fit into a lightweight EV passenger vehicle.   The project spans a broad range of disciplines and builds on RVT’s basic research and development in Internal Combustion Engines (ICE), Electronica’s non-rare earth super-generators and novel control strategies.  PURE combines these using MIRA’s world class expertise in co-design and low carbon vehicle integration, in conjunction with Productiv’s ability to industrialise low Carbon automotive technologies.

Key Targets

  • 35 kW electric output;
  • Compact installation within 800 x 575 x 400 space;
  • <100 kg;
  • <€2,000 at niche volume of 20,000 p.a.;
  • <€1,000 in volume production, >200,000 p.a.


PURE is co-funded by the Technology Strategy Board and the consortium partners.  Led by MIRA Ltd, and working in partnership with RVT Powertrain Ltd, Electronica Products Ltd and Productiv Ltd. The PURE project will enable the partners, two of which are SMEs, to establish a world leading position in auxiliary power units for EVs, with a clear route to industrialisation and commercialisation, demonstrating the value of the whole system as well as the individual components. PURE will also demonstrate:

  • The ability of an efficient APU to significantly reduce vehicle CO2 emissions and particulate and NOx emissions;
  • The business case for the partners to enter production and establish new revenue streams within 7 years;
  • The opportunity for the UK to manufacture such innovative technologies, create growth and jobs in the UK supply chain.

What next?

In the future, the project also looks to offer a route to market for a number of further innovations to be developed including:

  • High efficiency ICEs;
  • Generators;
  • Thermal management techniques;
  • Scalability of the technologies for other applications.
