Development progress in the flow cell technology used in the QUANT 48VOLT allows extreme performance (>560 kW) for the very first time from a low-voltage architecture (up to 48 V). The surface of the flow cell’s membrane structure has been nanotechnically optimised and now has an increased reactive surface, without significantly changing the overall dimensions of the individual cell. In addition, the QUANT 48VOLT has six nanoFlowcell® flow cells which can be activated simultaneously to generate greater drive energy by discharging more bi-ION electrolytes.

The drive motors too are completely new. Unlike conventional electric motors with intricate copper windings, the four innovative 45-phase, 140 kW low-voltage drive motors have a solid stator structure made of light alloy.

This makes the motors lighter, more compact and more economical. They also provide the electric sports saloon with tremendous acceleration, enabling it to reach its electronically limited top speed of 300 km/h with ease and without acceleration gaps. The drivable range is expected to be around 1,000 kilometres – 25 percent more than that of the high-voltage QUANT sports car (QUANT FE).

A cutting-edge VCU controls the entire electric powertrain and regulates the flow of charging and drive currents. Depending on the driving mode and the power requirements, the VCU switches three of the six flow cells in the QUANT 48VOLT either on or off.

QUANT 48VOLT not only clears up any scepticism people might have regarding the performance of electric cars – it addresses safety concerns too. With its low-voltage drive system, the QUANT 48VOLT automatically becomes the safest electric sports car concept on the market today.
