NAWA Technologies, maker of next-generation ultra-fast energy storage systems, revealsNAWARacer,astunning zero emission motorbike concept which features a world-firstin electric powertrains:a ‘hybrid’battery. Appearing at the Consumer Electronics Show (CES) in Las Vegas on 7thJanuary 2020, NAWA Racercombines NAWA Technologies’revolutionary ultracapacitors–which offer tentimes more power and five times more energy than existing tech –with conventional lithium-ioncells. Marking the first time an electric motorbike has used ultracapacitors, the hybridsystemoffers the best of both worlds: ultra-fast charging, incredible energy recoveryand highpower output thanks to the ultracapacitors, and a long continuous range thanks tobetter lithium-ionmanagement. Inspired by theoriginal café racersof London in the 1960s, which were lightweight,powerfulbikesused for short, quick rides between cafés, NAWA Racerbuilds on thesethemes,boasting a raftof efficiency benefits that make it perfect for the city, with features other e-motorbikes cannot offer.

Next-gen ultracapacitors: the key tounlockinga hybrid battery

The basis of NAWA Racer’sadvantage is the company’scarbon-based ultracapacitors,which charge and discharge in seconds, capable of pickingup energy from regenerative braking and supplyingit back to an electric motor very quickly. They can do this millions of times over without degradation, offering very fast energy transfer, unlike lithium-ion. But although they have five times moreenergy storage than existing technology, lithium-ion does still offer greater overall capacity By integrating these ultracapacitors into a lithium-ion system, the result is a battery that hasmuch more efficient overallperformance, greatly reducing the charge and discharge cycles the lithium-ion battery performs,extending the life of the entire system.Regardless of electric vehicle, from motorbike to car, the efficiency improvements made by a hybrid ultracapacitor battery system can reduce the size of the lithium-ion battery byup tohalf, or extend the rangebyup to double –or a combination in between depending on use. This is especially the case where there is a lot of brakingandaccelerating, such as in an urban area.

Energy efficient and lightweight

Located in thebike’s toptank areais an arrangement of NAWA Technologies’ own ultracapacitors, known as NAWACapandoffering0.1 kWh,which boost a lithium-ion batterymounted low in the chassiswhere the internal combustion engine would otherwise be. Re-usingmore than80 percent of the energy captured from regenerative braking –lithium-ion can only re-use 30 percent –NAWACapbringsmajorleaps in efficiency, allowingNAWA Racerto use a much smaller lithium-ion battery than wouldotherwise be possible:just 9 kWh, around half the size of a conventional electric sports bike’s battery. The NAWACap packitself is lightweighttoo, weighing as little as 10 kg, andcombinedwith thebike’scarbonfibre frame andcomposite body panels,NAWA Racertips the scales at just 150kg, a weight saving of 25 percent over conventional electric sports bikes. This lightweight, compact hybrid battery system results in exceptional range. Thanks to its lithium-ion battery, NAWA Racercan cover150kmon a mixed cycle, including highways. Butthe city is where it really shines. Bycapturingso muchenergy from stop-start riding, releasing it again as acceleration, NAWA Racercan double its range in an urban area, covering300kmbetween charges. The NAWACap pack recharges in just two minutes and the entire battery can be charged to 80 percent in one hourfrom a home supply.

Exhilarating performance –at all times

As standard, the hub-less rim motor produces 100PS, rocketing NAWA Racerfrom rest to 100km/hin comfortably under three seconds, onto a top speed in excess of 160km/h. And no matter the charge level ofthelithium-ion battery, this accelerationwill always be availablebecause of the ultracapacitor’shighpower characteristics, which continually maintain responseand performance. Unlike with a regular fixed battery, NAWA Racer’s NAWACappack canalsobe removed and swapped for different levels of performance,allowing riders totune their bike’scharacteristics. NAWA Raceralso features a ‘Race’mode, which gives a boost of ultracapacitor power. This is inspired by theoriginal days of the café racer, when riders would go ‘record racing’–short,fastrides to an agreed point and back, before a record had finished on thecafé’sjukebox–and ‘Race’ mode is designed to givethe rider the edge on the return journey (ortoovertake slower traffic in every day riding). It also features an‘Eco’ mode,where energy recovery is further maximised

Minimalistic design

Intended toturn heads as well as offer a ground-breaking electric powertrain, NAWA Racerbrings a modern twist to its retro looks with simple, smooth lightweight composite panels, paintedaluminium and copper,based on a strong, stiff but light carbonfibre frame. Details such as LED lighting for the headlight and taillight, anodised matteblack suspension forks, nubuckleather saddle in vintage camel and a hub-less rim motor complete the striking look.For the project, NAWA Technologies has been supported by expertdesign andengineering services provider Envisage Group(, who hasworked with NAWA Technologies to develop the design of NAWA Racerand realise a dynamicdemonstrator for CES. Envisage focuses on creating bespoke, perfectly-engineered vehicles and products, with a global reputation for craftmanship, working with the world’s largest and most prestigious OEMs and product manufacturers. Although simply a vision of an electric motorbike of the future for now, NAWA Racer’shybrid battery system can be applied to all forms of electric vehicleand the technologycould go into production in the very near future. At CES, NAWA Technologies is located at Eureka Park, Stand G, Booth 50463, the same stand as the CEA, the French Atomic and Alternative Energy Commission,from which it wasspun off in 2013. Visitors are invited to see NAWA Racerand experience itshybrid battery system for themselves. Pascal Boulanger, Founder, Chairman of the board, CTOand COO of NAWA Technologies, said: “Electric vehicles are still limited by the energy their batteries can store and the time it takes to recharge them. Apromising solution is to combine lithium-ion with ultracapacitors –but until now theyhave nothad enough energy, been tooexpensive and lacked the power capabilities to easily integrate them within a hybridbattery system. NAWA Technologies’ ultracapacitors offer the complete solution, the lowest internal resistance–allowing DC/DC converter-less integration –and lower cost.Taking performance, range, efficiency, weight and charging time to new heights, this system is also more environmentally-friendly. Our ultracapacitors are based on carbon,which is naturally occurring and abundant, soour hybrid packs also reduce the need for lithium mining.” Ulrik Grape, CEO of NAWA Technologies,said: “The NAWA Raceris our vision for the electric motorbike of tomorrow –a retro-inspired machine, but one that is thoroughly modern. It is lightweight, fast and fun, perfect for an emission-free city commute that will put a smile on your face. But it also lays down a blueprint for the future. NAWA Technologies’ next-gen ultracapacitors have unleashed the potential of the hybrid battery system –and this design of powertrain is fully scale-able. There is no reason why this cannot be applied to a larger motorbike, or car or other electric vehicle. And what is more, this technology could go into production in the very near future.” NAWA Technologies’ core market is the production ofits next-generation ultracapacitor cells. With development completed, and 10 M€ fundingalreadyraised from historical and new investors, NAWATechnologiesbeginsthe mass production phase over the coming year. A first of its kindcell production line will be installed at its Aix-en-Provence facilityand, at full production,NAWA expects to achieve a capacity of inexcess of 300,000 cells per month.

These will befirst usedglobally in a wide range of electrical systems including power tools, automated guided vehicles and sensor basedIoT markets.With theglobal market for ultracapacitors estimated to grow to €2-3bn in 2023, NAWA Technologies is ideally positioned to take advantage of increased demand.
