NanoFlowcell Holdings is following-up its Quantino EV from the 2016 Geneva Motor Show with an interestingly-styled sports car called the Quant 48V.

Claimed to have 560kW on-tap, the 2+2 seater is said to cover zero to 100km/h in just 2.4 seconds on the way to an electronically-limited top speed of 300km/h.

NanoFlowcell claims the range between refills is around 1000km – 25 per cent more than its previous high-voltage Quant FE sports car shown in Geneva two years ago. Refills? As reported by TMR in our previous reports on on nanoFlowcell vehicles, there are two 175-litre tanks each containing non-toxic, non-flammable ionic fluids – one positively charged and the other negatively charged.

The advance for this spots car comes from a complex new flow cell drive – while today’s electric vehicles use a battery voltage often in excess of 400V, as the name suggests, the Quant 48V concept uses low-voltage (48 Volts) technology.

According to nanoFlowcell, based in Liechtenstein, achieving 560kW of output and long range at such low voltages is achieved via an improved membrane structure of the nanoFlowcell, and the connection of six flow cells.

“Over two-and-a-half years of development, the company successfully applied a special nano process to increases 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,” the company explained.

Using six flow cells facilitates more bi-ION electrolyte to be discharged in a shorter timeframe to create more energy generation. And the new cell design enables the nanoFlowcell to process more than 600Wh of energy density in the bi-ION electrolyte solution.

The innovations don’t stop there. Drive comes from four 140kW compact, light-weight and cheap-to-produce 45-phase low-voltage motors which use a solid aluminium net structure rather than the familiar copper windings.

NanoFlowcell is also claiming safety gains with its low voltage system – the flow cells’ poles can be touched with no risk of injury (a positive step for motorists and first responders in the event of a crash) and the electrolyte liquids are not flammable or explosive.

Further, the low voltage parts can be manufactured at a lower cost (the costly safety measures inherent in high-voltage batteries do not apply) and servicing does not require technicians trained in high voltage system.
