Flow Cell Superlimo Begins German Road Trials



Somewhere between regular batteries and fuel-cells are flow cells. Comprised of liquid electrolyte that circles through a membrane between two tanks, creating an electrical charge that powers an electric drivetrain. Specifically, the electric drivetrain in the Quant e-Sportlimousine.

What makes the Quant s-Sportlimousine a superlimo, exactly? Try an all-electric 0-60 sprint in just 2.8 seconds while the Quant powers its way to a top speed of nearly 220 MPH. That stunning performance comes from the nearly unbelievable claim that more than 2000 lb-ft of torque is available from the Quant’s 4 in-wheel electric motors – and all that without burning a single drop of gasoline.

How’s that for super?

The superlimo’s makers are also claiming that all that performance doesn’t come with an appreciable loss of practicality. The luxurious, gull-wing superlimo is, apparently, able to carry a driver and 3 passengers in the lap of luxury for more than 370 miles … and I’d be the loudest one shouting VAPORWARE! if it weren’t for the fact that one of Europe’s strictest roadworthiness agencies has already given the car a green light.

There just might be something to this flow-cell thing, after all – along with claims that the flow cell technology itself should weigh a lot less than a lithium-ion battery pack while delivering superior performance. That’s over my head, though. What do you guys think? Is the flow cell a real alternative to heavyweight battery packs, or did the Quant guys manage to pull one over on the TÜV? Let us know what you think of the superlimo concept in the comments, below.

    Vanadium redox flow cells, as far as I’ve researched them, are not as energy dense as LiFePo4 batteries (one of the least energy dense lithium battery chemistry). I call Bullshit. No way they can get that kind of range.

    Beautiful design, though.

    It’s hard for a casual reader to know the truth of these claims. But the world of electric/plug in/fuel cell cars is bubbling with the ferment of new ideas. ONE of them is going to be the way forward for transportation in the modern age. But is this the one? I just don’t know.

    But I agree with egogg – beautiful design! : )
