Fully Ridable E-Motorbike Prototype Ready for Summer

Nawa Technologies, AKKA Technologies, FAAR, Pronergy and YSY Group announced that Nawa Technologies' concept e-motorbike, the NAWARacer, will debut as a dynamic prototype in the coming months.
NAWARacer was initially designed as a demonstration project, illustrating how Nawa Technologies' next-gen ultracapacitors, called NAWACap and reinforced composites solution NAWAStitch, can be applied to a real-world electric vehicle (EV) powertrain. Following a successful global reception, the decision has been taken to develop a fully functioning, rideable prototype - and an experienced consortium assembled to bring it to life. For further information see the IDTechEx report on Electric Two-wheelers 2021-2041.
"We had such a fantastic response to our NAWARacer concept at CES 2020 that we had to take the next step and showcase what our NAWACap technology truly can do," said Pascal Boulanger, Founder of NAWA Technologies, and CTO. "In order to develop a fully dynamic prototype, and best reflect our next-gen energy storage technology, a world-leading consortium has been brought together to design and build a fully functioning version."
The prototype will feature a world-first in electric powertrains: a 'hybrid' battery which combines Nawa Technologies' own revolutionary ultracapacitors, NAWACap, with conventional lithium-ion cells. These are then merged in an innovative electrical architecture, enabling the best of both energy sources, opening up new possibilities for electric vehicle powertrains, with NAWACap playing an equivalent role to a turbocharger in an internal combustion engine.
This hybrid ultracapacitor battery system greatly improves energy efficiency, reduces charging times and extends entire system life. Applicable to any electric vehicle, the efficiency improvements can reduce the size of the lithium-ion battery by up to half, or extend the range by up to double - or a combination in between depending on final design.
For the initial design of the NAWA Racer concept, Nawa Technologies was supported by design and engineering services provider Envisage Group - based in Coventry, UK.
Expert e-mobility consortium
To develop the first NAWARacer dynamic protoype, an expert development partnership has been assembled with skillsets across automotive engineering, R&D, battery management, electronics, powertrain, systems integration and prototype realisation - within the framework of the HYDEALIST project (Hybrid storage and fast-charging for AGV in logistics), funded by InnoEnergy (the European innovation platform for clean technologies).
The development of the motorbike's unique e-powertrain and, in particular, the aluminum body - which structurally integrates the battery within the chassis, negating the need for a conventional frame - and the in-wheel motor, is led by AKKA Technologies. AKKA's team of experts will develop NAWARacer's ride and handling characteristics, with particularly focus on the motorbike's new rear arm design and advanced suspension system.
The development of NAWARacer's electronic power distribution system is led by Pronergy, a subsidiary of FAAR SAS located in Paris. This distributes power according to vehicle mode and rider demand. For this first dynamic prototype, a new switching unit has been developed allowing both NAWACap and the lithium batteries to provide energy, maximising the benefits of both technologies in terms of performance and efficiency.
FAAR heads up the development of NAWA Racer's Battery Management System software control ECU electronic architecture, bringing its embedded energy management expertise to the project.
Nawa Technologies, the inventor of the NAWARacer and its hybrid power-battery system, is supplying NAWACap - its next-generation ultracapacitors - integrated in a light, compact, modular and communicating pack that can be used in many other applications.
Further expert assistance comes from YSY Group, based in Lille, France who complement NAWA in motorcycle testing.
The dynamic prototype will be revealed and demonstrated on track just before summer 2021, depending on current Covid-19 restrictions.
While Nawa Technologies has no plans to make or sell a production version of the NAWARacer, it is open to approaches from appropriate partners interested in taking this e-motorbike to the streets.
