At the 2014 Geneva Show little known nanoFlowcell AG unveiled the Quant e-Sportlimousine, a futuristic sedan powered by an electric powertrain with four motors and “flow cell technology”, which stores energy in tanks of electrolyte solutions. In the following months, the vehicle was approved for use on public roads in Germany and Europe by SGS-TÜV and .
Now the latest development of the project is taking shape in form of two concept cars.
QUANT F Concept
The QUANT F is a direct evolution of the original Quant e-Sportlimousine: the 5.25-meter long, four-seater sedan has a new 2-speed automatic transmission developed in-house and features high performance figures, with an increased maximum rated voltage of 735 V (previously 600 V), a 1090 PS/802kW output and a top speed of over 300 km/h and a range of 800km.
This is made possible by the particular powertrain, which includes two 250 liters tanks, with two ionic fluids – one with a positive charge and one with a negative charge.
The system feeds over 50 amperes of current into a newly developed buffer system. In turn, this buffer system is briefly able to supply over 2000 amperes when needed for full performance.
The QUANTiNO is a smaller, more affordable model, with a rated voltage of only 48 V which allows to achieve a power output of four times 25 kW, corresponding to around 136 hp, through a combination of nanoFlowcell®, buffer system and electric motors.
According to the company, “this set-up provides us with a top speed of over 200 kilometres an hour in all-electric mode and a range of over 1,000 kilometres”, as explained by Nunzio La Vecchia, Chief Technical Officer at nanoFlowcell AG.
Measuring 3.91 metres in length, the QUANTiNO is a 2+2-seater original crossover. the main proportions are defined by the huge 22-inch wheels, while the surfacing and the styling details adopt a design language similar to that of the QUANT F.
With its two 175-litre tanks, the QUANTiNO is able to carry 350 litres of ionic liquid in total – one tank with a positive charge and one with a negative charge. The refuelling process is similar to the procedure which is customary today, the sole difference being that two tanks are filled simultaneously, each with a different fluid.
