How you can finish EV range anxiety – Nanoflowcell’s tech described

Vehicle manufacturers are eager for an alternative choice to the combustion engine, one that’s sustainable, affordable and free from compromise.

A Liechtenstein-based company known as Nanoflowcell claims with an answer: an electrical vehicle that may be chock-full in the pump with non-flammable, non-toxic fluid and it is stated to provide a variety much like those of conventional gas or diesel cars.

Nanoflowcell revealed its first concept vehicle, the Quant E, finally year’s Geneva motor show. This season it came back using the Quant F and far smaller sized Quantino two-seater. The 3 cars are propelled by four wheel-mounted electric motors provided with electricity from the flow cell battery.

The flow cell concept is dependant on the Redox (reduction and oxidation) flow cell technology trialled by NASA in early 1970s. Redox flow cells generate electricity when given with two electrolytic fluids, one positively billed and something negatively billed, kept in separate tanks.

The flow cell is split up into two halves with a membrane, with positively billed electrolyte flowing through one for reds and negatively billed with the other. Ion exchange happens with the membrane, generating electricity.

Normally, flow cells could be replenished by recharging like every other battery, or just by replacing the fluid. The Nanoflowcell works differently. Because it discharges, water-based ‘ionic’ fluid electrolyte evaporates, departing the storage tanks empty and prepared for refilling. Quant cars could be refuelled in a pump utilizing a two-pronged nozzle to fill both ‘positive’ and ‘negative’ tanks simultaneously.

Based on chief technical officer and inventor from the Nanoflowcell Nunzio La Vecchia, “the ionic fluid is non-flammable and non-toxic, and you will find no emissions or high pressures involved”. Consequently, he adds, on-board storage is easy and creating a filling station network easy and relatively cheap.

Traditional flow cell designs do not have the finest volumetric energy density, meaning a sizable volume is required to store an acceptable quantity of energy. Nanoflowcell claims its new fluid formulation improves this, giving five occasions the power capacity of the conventional flow cell. La Vecchia states 80% from the development to date went into increasing the chemistry from the ionic fluids and 20% into the style of the flow cell.

The Quant F has a variety of 497 miles and also the Quantino 621 miles, but Nanoflowcell concedes they still need carry a large amount of fluid – 500 litres within the situation from the Quant F – in 2 250-litre tanks weighing half a tonne. The Quantino carries 350 litres of fuel, which weighs around 350kg. In comparison, a variety Rover TDV6 carries 85 litres of diesel weighing 72kg.

That stated, unlike gas, diesel or hydrogen, liquid fuel is simple to distribute through the structure of the vehicle if required, especially if it’s as harmless as Nanoflowcell claims.

A flow cell is nice at producing a steady flow of one’s although not the transient spikes of power required with a driver. Therefore the Nanoflowcell feeds capacity to a 2000A supercapacitor serving as a buffer to provide instant capacity to the 4 wheel motors as a result of the accelerator pedal.

The flow cell is effective, using the Quant F’s system generating 735V and 92A. The Quantino, though, comes with an intrinsically safer low-current system, just 48V but “more than 200A”. In tangible terms, which means the machine delivers enough electrical power to power four 25kW, 134bhp electric motors and generate a quoted top speed in excess of 125mph. In comparison, a Nissan Leaf’s battery produces 360V.

The Quant E acquired TüV Süd approval to become driven on public roads this past year, and the organization has become seeking homologation for that Quant F, letting it enter production. “One hundred percent from the exterior qualifies and we’re 90% there using the interior,” states La Vecchia. The Quantino, using its low-current system, may also be ready for homologation. The following stage along the way is crash testing, and La Vecchia hopes homologation is going to be completed the coming year.

At Geneva, the Quant F grabbed the headlines using its supercar looks, claimed 1075bhp, top speed in excess of 186mph and -62mph performance of two.8sec. But that’s really minor what really matters is the potential for Nanoflowcell technology to provide a good vary from a complete ‘charge’, the capacity for refuelling with liquid fuel just like a conventional vehicle very quickly, the relative simple creating or converting a network of filling stations and also the benign nature from the fuel. Challenges can include vehicle dynamics because the Quant F, weighing 2300kg with full tanks, sheds over 20% of this mass because the fuel can be used up.

Nanoflowcell doesn’t have intends to build cars in-house beyond prototype stage and it is providing the technology under licence.

No licences happen to be adopted up to now, but La Vecchia states there’s been interest from some vehicle company bosses. Flow cell technologies are being considered globally by energy companies for storing off-peak electricity in the grid. Nanoflowcell also really wants to extend its very own technology with other way of transport for example trains, trucks, shipping as well as aerospace.

    Is this a sequel to the Xbox 360&1quo;s indie Aban Hawki1 and the 1000 spikes? or a remake with some extra features?
