nanoFlowcell’s newest concept takes electric mobility to a safer and more efficient level

One of the biggest problems with hybrid and electric cars is that they require high voltage, but nanoFlowcell has developed technology that allows low-voltage electric drive without the need for massive supercapacitors in a standalone system. This latest development is set to be showcased in the model you see here: the Quant 48Volt.

The car itself looks painfully similar to the 2014 Quant e-Sportlimousine with a 2+2 seating configuration, but what’s more important is the electric drive system that uses a lower voltage to deliver 560kW (750 horsepower) to all four wheels in a light, safe, and environmentally compatible vehicle.

This kind of power delivery from a low-voltage system is made possible by the brand’s ability to increase the size of the flow cell’s membrane surface, which multiplied the reaction surface of the cell without bringing on an increase in size.

With the ability to deliver so much power from such a low-voltage system, nanoFlowcell is boasting the increased safety inherent to the design. The way the system is structured, the poles of the flow cell can be touched without any risk – ultimately meaning that road users and first responders don’t have the risk of being shocked by high voltage in the event of a serious accident on the road. On top of that, the electrolyte liquids used for the flowcell aren’t flammable or explosive – something that can’t be said about the common lithium ion batteries that electric and hybrid cars on the road are using today.

This newest development and nonoFlowcell’s newest concept car is set to make its debut at the 2017 Geneva Motor Show, so let’s dive on in a take a quick look at what’s going on here.

At a glance, it seems like we’ve seen this design before, but the car itself is unique in its own way. Up front, that low and strategically designed nose provides an aerodynamic prowess that screams performance. The sleek headlights in the corners, the large and recessed corner vents, and the little lip below the air dam are all, somehow, aesthetically pleasing on the eyes. Then you’ve got those sculpted front fenders that aren’t quite muscular but give the car a sense of aggressiveness. Just like the trim element on the roof and along the bottom side of the door, the trim elements in the corner vents take on the same color.

Moving over to the sides, the rear sitting greenhouse, large door, and fastback-like slant to the rear profile all provide a dominating and intriguing design. The rear haunches aren’t as pronounced as the arches on the front fender but provide a somewhat muscular appearance. The recessed nature of the doors compared to the lower portion of the body present a futuristic look that has just a hint of elegance and should provide some downforce – a necessity for the 750 ponies of electric goodness lurking beyond the body.

At a glance, it seems like we’ve seen this design before, but the car itself is unique in its own way.

Walk around to the rear of the 48Volt, and you’ll find a design that is much more aggressive than any other part of the car. First, that copper/bronze colored element on the rough dips down in the middle to follow the central contour of the roof and the rear glass. The rear glass itself helps to give the rear end a supercar-like appearance, while the thin, LED taillights give the car a futuristic look.

The sharp lines and contours of the insert above the rear fascia provide a lot of character while the lower insert is situated in a way that allows the fascia to come to a sharp point on each side, with the only thing connect the left and right being a small strip that runs between the two inserts.

The exterior design is bold, sexy, and pleasing from every angle.

Down below, that lower insert takes the form of a massive diffuser with a single vertical slat right in the middle that is flanked by a pair of bronze inserts that are similar to the front corner vents but more rectangular. Horizontal slats are built into the center of the inserts. The lower portion of that diffuser is primarily smooth but is angled just right to allow airflow from under the car to disperse in an upward direction.

All told, the exterior design is bold, sexy, and pleasing from every angle. It’s not something that you’ll be able to afford earning a median salary, but this car gives us a quick glance into the future of sporty, electrifying design that is quite literally on the horizon as the automotive world continues to transition into a whole new realm of design.


The only look we’ve gotten at the interior of the 48Volt is from a side view of the exterior with the gullwing doors wide open. It does reveal the 2+2 design but also presents a pair of sport front seats with lots of side support on the seat back and seat cushion. Meanwhile, the rear seats appear to take on the same exact form, but may not be quite as supportive. The seats are two-tone in nature and are primarily black with a shade of brownish gray encompassing the outer edges and various strips in the center of the seat. The seats are nearly identical to those seen in the Quant FE and could very well be the same exact seats.

As far as the rest of the interior, it’s hard to say with 100-percent certainty what is going on, but considering the car is pretty similar to all of the other nonoFlowcell concepts I’m willing to bet that we’ll see a similar interior as well.

As far as the rest of the interior, it’s hard to say with 100-percent certainty what is going on, but considering the car is pretty similar to all of the other nonoFlowcell concepts I’m willing to bet that we’ll see a similar interior as well. This means the main portion of the dash will likely wraparound and blend in with the curvature of the doors, while also circling inward and shooting straight back to create a center console of sorts. This also creates an individual bubble for each of the four seats, providing each passenger with their own space. On the other concepts, the dash, main door trim, and center console were all made from high-quality wood, so that will likely carry over as well.

Mounted to the top of the hash will sit a massive is the centerpiece of the whole interior – a large, wide digital display screen that serves as an instrument cluster, navigation, and vehicle information display, and infotainment system. Pertinent information like speed, range, charge level, etc. is presented to the drive ahead of the flat-bottom, flat-topped steering wheel. In the center sits the display that provides most of the information about the car itself, while the right side is reserved for various tasks like choosing music – something that’s perfect for that co-pilot on long road trips.

While the interior and exterior of the Quant 48Volt are undoubtedly similar to that of the cars that came before it, the inner workings of the drivetrain is what really sets it apart. All of the other models thus far have had high-voltage systems. The Quant FE, for example, make use of nanoFlowcell technology, but ran on 500 to 700 volts, peaking at 735 volts. The capacity of that model was 70 kWh, with supercaps buffer system that maxes at 2,000 amps. Power delivered computes to 790 horsepower and an astonishing 2,138 pound-feet of torque. That’s enough for a 2.8-second sprint to 62 mph and a top speed of 186 mph. Jump into the future and look at the few specs we have for the Quant 48Volt, and the difference is as clear as the morning sun without a cloud in the sky.

The 48Volt is lighter, safer, and offers more range than the high-voltage cars that came before it.

As opposed to a 700-volt system, this baby – as its name suggests – runs on just 48 volts – a relatively low and safe voltage. And, it’s able to deliver “extreme” performance through four electric motors to the tune of 560 kW or 750 horsepower – just 40 horsepower less than the Quant FE and its 700-volt system. Astonishing. Those four motors are 45-phase low-voltage units that are each good for 140 kW of power. There’s no word on torque output at this time, but according to nanoFlowcell we’re talking about the sprint to 62 mph coming in as fast as 2.4 seconds with top speed limited to 186 mph. Meanwhile, its stated range is 1,000 km or 621 miles. Ultimately, it’s said to be the lightest, safest, and environmentally sound powertrain system for electric vehicles.

So to put all of this into a few words, the 48Volt is lighter, safer, and offers more range than the high-voltage cars that came before it. And, on top of that, the advancement this car represents means that build production models will be significantly cheaper than it would have been if based on the high-voltage systems used to this point and repair technicians won’t need that high-voltage specialist training. That computes to cheaper upkeep and maintenance in the long run. Well done nanoFlowcell.

So, will this be the car that makes it into production and rewrites everything we know about electric production cars? Obviously, a model like this would be priced well above that of a Nissan Leaf or even a Tesla Model 3, but the technology behind it can surely be adapted to smaller, more affordable cars and with 600+ plus miles worth of range, it’s not likely that range anxiety would be an issue either. Regarding design style, luxury, and technology, the Quant 48Volt is on point, and it would be very interesting to see what the toned down production model will actually look like. But, before that happens, this baby needs to make its debut at the Geneva Auto Show, where we may learn even more about it. What do you think about it so far? Let us know in the comments section below.

Press Release

nanoFlowcell Holdings announces that it will present its latest advances in flow cell research at this year’s Geneva International Motor Show. Wrapped in the extravagant bodywork of an electric sports car that is utterly unique in the automotive industry, the QUANT 48VOLT, the company is showcasing the state-of-the-art in modern flow cell research. nanoFlowcell Holdings has succeeded in developing the first ever controllable flow cell that enables a standalone design for low-voltage electric drives without the need for heavy and expensive supercapacitors. And the 2+2-seater has no lack of power at its disposal – the 560 kW all-wheel drive delivers top speeds of up to 300 km/h. However, nanoFlowcell® 48VOLT is not just about powerful performance, but is also currently the lightest, safest, most environmentally compatible and most economical drive system available anywhere for electric vehicles.

What makes the QUANT 48VOLT so special is the radical new design of its flow cell drive. The previous model, the QUANT FE, achieved its exceptionally sporty performance figures with a 700 V high-voltage drive system, whereby the QUANT 48VOLT runs entirely on low-voltage technology.

To compete in acceleration and power output with vehicles powered by internal combustion engines, conventional electric vehicles need electric drive systems with a battery voltage of 400 V and more. In fact, the automotive industry is currently contemplating increasing the voltage in electric vehicles to 800 V in future.

With the QUANT 48VOLT, nanoFlowcell Holdings questions this development alternative for electric-car technology and makes a globally unique statement: Flow cell technology in the QUANT 48VOLT delivers extreme performance (> 560 kW) at safe battery voltages (48 V). The key is the improved membrane structure of the nanoFlowcell® and the series connection of several flow cells. Over two-and-a-half years of development, the company successfully applied a specialist nano process to increase the size of the flow cell’s membrane surface in a way that multiplied the reaction surface by several orders of magnitude without compromising the compactness of the cells. Another innovation in the QUANT 48VOLT is the first series connection of six flow cells, enabling more bi-ION electrolyte to be discharged in a shorter space of time, thus allowing more energy to be generated. Furthermore, this new cell design has also been configured to enable the nanoFlowcell® to process a higher energy density in the bi-ION electrolyte solution (more than 600 Wh/l).

The drive has also been completely redesigned. Used for the first time in the QUANT 48VOLT are innovative 45-phase low-voltage motors, which facilitate high power paired with minimised cross-sections in the electrical wiring. The special feature of these low-voltage motors is their solid aluminium net structure, which replaces the complicated copper windings used in conventional electric motors. This reduces the volume of the motor relative to its power output, while lowering weight and cost, and simplifying series production.

Questions on the power of the new nanoFlowcell® 48VOLT flow cell drive are quickly answered: The 560 kW (4 x 140 kW) electric motors in the QUANT 48VOLT accelerate the electric sports car from zero to 100 km/h in 2.4 seconds and onwards with no loss of acceleration to a top speed of 300 km/h (electronically limited). The anticipated range is around 1,000 km – 25 percent more than that of the high-voltage version of the QUANT FE sports car.

The QUANT 48VOLT not only dispenses with the performance scepticism levelled at electric vehicles but also addresses the safety concerns surrounding them. With an electric drive that operates at low voltages across the board, the entire vehicle is inherently safe from an electrical standpoint. The way they are structured, the flow cell’s poles can be touched with no risk to life or limb. In contrast to conventional lithium-ion battery systems, there is absolutely no danger of road users or first responders suffering an electric shock from a nanoFlowcell 48VOLT system, even in the event of a serious accident. Furthermore, the nanoFlowcell® electrolyte liquids are neither flammable nor explosive.

Standardisation for industrial-scale production of the low-voltage parts for a nanoFlowcell® 48VOLT electric car also offers substantial benefits – no expensive measures relating to high-voltage safety have to be met, leading to significant cost reductions in development, production and maintenance. The technical servicing of a nanoFlowcell® 48VOLT electric car can, for instance, be conducted by technicians without specialist high-voltage training.

The QUANT 48VOLT with nanoFlowcell® low-voltage drive is forward-looking electric mobility. The flow cell energy of the nanoFlowcell is not harmful either to health or the environment. In a low-voltage sports car like the QUANT 48VOLT, nanoFlowcell® 48VOLT technology demonstrates powerful performance and thus draws attention to what is currently the lightest, safest, most environmentally compatible and economical drive system there is for electric vehicles.

Further technical details on the world’s most innovative electric sports car are published in the QUANT 48VOLT press kit.

nanoFlowcell Holdings Ltd will display its latest QUANT vehicles with nanoFlowcell® 48VOLT flow cell technology from 7-19 March at the 2017 Geneva Motor Show in hall 1, stand 1244.

nanoFlowcell® is the product brand used by nanoFlowcell Holdings Ltd for its proprietary flow-cell based energy technology. nanoFlowcell is similar to a combination of battery and fuel cell, requiring for energy storage and conversion only a non-toxic, non-flammable and environmentally compatible electrolyte liquid called bi-ION, developed by nanoFlowcell Research GmbH. The cost of manufacturing the bi-ION electrolyte liquid on an industrial scale is estimated at substantially less than ten cents per litre. The distribution and sale of the electrolyte liquid is straightforward as its product characteristics mean it is not bound by any laborious environmental constraints and could be handled via existing refuelling infrastructures.

Under the QUANT brand, nanoFlowcell Holdings Ltd develops prototype vehicles with low-voltage electric drive for the purpose of testing the new flow-cell based nanoFlowcell technology. In 2016, the company demonstrated the potential of an electric vehicle powered by nanoFlowcell mainly with its QUANTiNO 48VOLT technology showcase, a road-legal mid-size sports car with nanoFlowcell low-voltage drive able to run fully electrically for upwards of 1,000 kilometres – with a top speed of 200 km/h and an acceleration from zero to 100 km/h of less than five seconds.

In short, QUANT powered by nanoFlowcell is a feasible form of electric mobility that protects the environment without compromises in comfort, performance or cost.

nanoFlowcell Holdings Ltd is an innovative research and development company in the field of flow cell technology and its applications. Besides the prototype development of electric vehicles under the QUANT brand, the company also conducts research into the opportunities for using nanoFlowcell® technology in other sectors and industries.
