“The QUANT e-Sportlimousine is a research vehicle for road testing innovative energy storage systems, focusing especially on development and improvements in flow cell battery technology. The QUANT e-Sportlimousine is neither a show car, nor a concept car. It is the first automobile to be fitted with the nanoFLOWCELL(R) that is also designed from the ground up to meet all homologation requirements,” according to Nunzio La Vecchia, Technical Director of nanoFLOWCELL AG.
Flow cells combine aspects of electrochemical accumulator cells with those of fuel cells. Liquid electrolytes are kept in 2 tanks and circulated through the cell. A membrane separates the 2 electrolytic solutions, but allows electrical charge to pass through, thereby producing power for the drive train.
“The advantages of the nanoFLOWCELL(R) lie in its high charge density, high performance density, and its light weight compared to conventional energy storage systems. Furthermore, it contains no harmful substances, no moving parts, and it is very efficient,” explains Nunzio La Vecchia.
At a nominal voltage of 600 V and 50 A nominal current, the system achieves continuous output of 30 kW. nanoFLOWCELL(R) has a 5-times greater performance-by-weight than current lithium-ion technologies that power most current day electric vehicles. This gives it a driving range 5-times greater than a conventional unit of the same weight.
