Low-voltage Technology

Not everything has to be high voltage

nanoFlowcell®:
compatible with high and low voltage

Our nanoFlowcell® can be used for both low-voltage and high-voltage applications. The various QUANT prototypes demonstrate the application of the nanoFlowcell® in different voltage environments. In the automotive sector, we have concentrated fully on low-voltage applications in the future because the merits of a low-voltage drive system outweigh those of a high-voltage drive system. Our QUANT electric sports cars are presently the most advanced and powerful low-voltage electric vehicles in existence – they are also the only ones to have road approval.

VOLTAGE IS NOT RELEVANT TO PERFORMANCE

Flouting high voltage conventional wisdom

Standard practice has been to install a high-voltage drive system with up to 800 volts in electric vehicles. Engineers have simply accepted the potential dangers inherent in high-voltage systems because there was no other way to achieve desired vehicle performance. But we are proving that electric vehicle technology is possible without high-voltage systems.

The scalable nanoFlowcell® 48VOLT low-voltage electric drive fits seamlessly into both compact cars like the QUANTiNO twentyfive and high-performance sports cars like the The New QUANT. It's the most powerful, eco-friendly, safe, and cost-effective EV drive system available today.

QUANT Low-voltage systems

Although we are not a vehicle manufacturer, we are an enthusiastic development team that can demonstrate the efficiency and modularity of nanoFlowcell® technology both in the lab and in real life through the construction of prototype electric vehicles. While our The New QUANT showcased nanoFlowcell® technology in a classic high-voltage application, we also developed a special low-voltage drive to power the QUANTiNO twentyfive.

In short, QUANTiNO is currently the only road-legal electric car in the world with a low-voltage drive. And with The New  QUANT, we have designed the first ever sports car in automotive history to feature a low-voltage drive, an innovation that further demonstrates the power of our nanoFlowcell® 48VOLT low-voltage drive technology.

In low-voltage systems, high currents require exceptionally large cable cross-sections and can lead to higher transmission losses. But the design of our nanoFlowcell® 48VOLT low-voltage drive solves this problem because  nanoFlowcell® generates high currents at a very low nominal voltage, making such currents perfectly suitable for a low-voltage drive.

In the QUANTiNO twentyfive and the The New QUANT, we have configured the low-voltage drive architecture in a way that significantly reduces the cable diameters usually required. This is an important development in the design of low-voltage electric vehicles since it reduces both costs and weight while opening up more design flexibility.

While high-voltage electric vehicles call for full-scale contact and arcing protection, low-voltage vehicles do not require it. The benefits are two fold: First, it provides greater safety for vehicle occupants, as well as for first responders in the event of an accident. Second, it results in an accelerated homologation process because functional safety is easier to implement in low-voltage vehicles.

We are currently the only manufacturer in the world able to achieve low-voltage drives in electric cars without compromising on total vehicle weight or performance. And we will make good use of this design advantage in the development of future QUANT electric vehicle concepts.
