The R&D company nanoFLOWCELL will present its new flow battery-powered electric vehicle at the Geneva Motor Show, which commences in March. The QUANT F is the successor of the QUANT E, which was the very first TÜV-approved flow cell-powered electric vehicle (EV). The QUANT F’s flow battery system (also called the nanoFLOWCELL) enables it to travel an estimated 497 miles (800 km) per charge. The nanoFLOWCELL system uses two tanks which are a whopping 250 litres each.
Nunzio La Vecchia, the CTO of nanoFLOWCELL, said:
The fact that we store the energy for our drive in a fluid provides us with enormous advantages over systems employed to date in the field of electric mobility. We can use all the cavities in the vehicle to transport the ionic fluid. As the fluid is neither flammable nor toxic, we believe we are absolutely on the right track with this medium.
That hefty weight doesn’t mean the energy density of the nanoFLOWCELL battery is low, as it can drive nearly 500 miles per charge, which exceeds the range of all electric vehicles on the market. It can also achieve a top speed of 186 MPH using its 1075 HP (800 kW) 375-volt, 2,000 amp, four-motor, AWD propulsion system (which uses a 50-amp current buffer), which surpasses the top speed of most EVs on the market. It can only sustain peak output for a limited time, though. The voltage will also be increased to 400-volts for “technical and economic reasons.”
As for the use of a clutch to activate the front axle, I am disappointed because this vehicle has four electric motors. Vehicles with this many motors can (and often are) made without any clutches or other mechanical power transmission devices. The omission of complex mechanical parts has the potential to improve reliability. Electric vehicles can be among the most mechanically simple (and reliable) vehicles. However, they may have a good reason for it. This vehicle’s performance and range are well above average.
Apart from that, according to Green Car Congress, in the carbon-fiber car, there’s a 2-stage aerofoil. “This is activated automatically on attaining a speed of 80 km/h (50 mph), applying additional negative lift force to the rear wheels for sporty driving, particularly at high speeds.”
