Electric taxi EVA to save weight and energy

The taxi EVA, designed by TUM CREATE combines all relevant success factors of an electric taxi for use in tropical megacities.

Responding to the demand for environmentally friendly transport in tropical megacities, Singapore's Nanyang Technological University (NTU) and the Technische Universität München (TUM) teamed up to form the TUM CREATE research program aimed at developing a specialized electric taxi for the needs of tropical megacities. At TUM CREATE over 120 researchers and engineers are working on cutting-edge research that covers topics ranging from the molecule to the megacity including areas such as: electrochemistry, electric vehicle batteries, embedded systems, air conditioning, simulation and modeling as well as infrastructure.

The team proudly presented their electric taxi EVA at the Tokyo Motor Show in November 2013, featuring a range of 200 km and a super-fast battery charging time of just 15 minutes allowing the car to be driven quasi non-stop through two 12-hours shifts a day.

The design team made extensive use of sandwich composite technology, both to save a maximum of weight and to improve the vehicle’s insulation in order to further reduce the car’s energy use for air conditioning. Recyclable PET-based Airex T92 foam core material was chosen for its outstandingly low resin uptake, high mechanical properties and cost efficiency and it was applied in many places throughout the entire composite body, such as roof, bulkhead, floor and component carrier system as well as the large battery housing.

Philipp Angst, director of product management at 3A Composites Core Materials, says: “We’re proud to have made a small contribution towards the success of this very innovative car concept. And we’re glad to see more and more lightweight sandwich applications in automotive concepts as well as small series, and believe that the industries are now gearing up towards more widespread use of these lightweight technologies in automotive applications.”
