PSA Group To Test Israeli Range-Extender

PSA Group confirmed it’s evaluating Aquarius Engines’s technology of a single-piston engine-generator for plug-in hybrid applications.

The Israeli startup was founded in 2014, and boasts an engine-generator that is “dramatically cheaper, smaller, cleaner and more efficient than existing power generators“.

Reportedly, PSA has agreed to fund further development, searching for a potentially revolutionary solution that would put the French carmaker into a better competitive position.

The PSA Group (Peugeot, Citroën and DS) badly needs some breakthrough technologies, as the company’s crisis (from 2012 to 2014) neglected R&D.

“PSA, which declined further comment, is pursuing an ambitious turnaround following a 2012-14 crisis that saw it fall behind competitors on research and development until it secured a cash bailout from the French state and China’s Dongfeng.”

PSA’s latest plan for electrification is to introduce 11 new plug-ins between 2019-2021.  Specifically, 4 all-electric vehicles (with 450 km NEDC range) and 7 plug-in hybrids.

Several prototype vehicles with Aquarius Engines are to be road-tested in 2017.

“In a rethink of engine fundamentals, Aquarius has pared the range extender down to a single piston that blasts to and fro inside a valveless 600cc cylinder, generating power from electromagnetic coils with each stroke. It delivers more than twice the overall energy efficiency of a typical combustion engine, according to simulations by German engineering firm FEV.”

“At an estimated $17,000 per vehicle, costs should undercut both conventional hybrids that come in closer to $25,000 and pure-electrics at around $40,000, the private company projects.”

    I have a Zero Pollution unlimited mile range extender in my EV. It’s a 20 inch fold up bicycle. It can go forever and is super efficient at over 2,000 MPGe on veggies.

      Well, I share the pleasure of biking with you, but , I doubt you pull your car with it.
      Neither do I.
      Better say It’ a pure human power device.
      Other than that, if successfult, I would take the Aquarius RE anytime in my Leaf.

      Not everybody has two healthy legs. And I want to see you go “forever” in Arizona 110° heat and arrive at your meeting in presentable state …

  2. Disappointed says:

    I would say that there is evidence that your “Range Extender” runs on Natural Gas !

  3. Kdawg says:

    How many kW can it put out?

  4. mhpr262 says:

    So, it is a linear piston engine coupled with an induction coil generator. AFAIK Toyota is currently developing something very similar. 40% efficiency is not so much greater than common stationary constant speed diesel generarors either.

    1. Djoni says:

      Afterthought:
      It’s the same scripted article in every newspapers shown on their site.
      Not very much information there
      They claim doubling the efficiency of an unknown setup.
      No number or report of testing.
      If it’s doubling the Toyota Prius engine said to achieve 40% efficiency, that would be incredible, but it’s mostly not.
      Then there’s this word from one of the advisory board, Efraim Wasservogel: “it reduces the required quantity of battery cells «that no one knows how to recycle”
      It look like something is fishy or dead wrong here.
      Because either, BMW, Nissan, Honda, GM, not to say Tesla is lying about the recycling of the battery that they have been doing, all of them saying to recycle battery, or this guy miscue something.
      Adding the fact that Nissan said they’ll pass having themselves look and create their own and conclude, that isn’t the way to go.
      I wish half of what I read come true, but this is highly doubtful.

      Yes, Toyota demonstrated theirs in 2014, a recent SAE paper says they solved some control problems. Interesting but still a research project.

      People have filed patents on these things for 80+ years. Toyota isn’t the only one with a working model:

      Perhaps Aquarius is closer to commercialization than the others, but there’s no evidence of that.

    That would make an interesting Rex, for instance to replace the one in the BMW i3. More compact, lighter, double yield so requiring half the tank size and going twice as far on a gallon.
    The idea has been around for quiet a while but none of the majors seemed to be willing to change from their sacred crank and shaft. Today it could still be interesting for super long range with a rex, but it may be late because batteries are now progressing fast and once around 150 KWh it will start to be enough for a whole day of driving. After that the energy is going to remain more or less the same with only the speed of charge increasing and the prices decreasing.
    Of course a direct free piston generator will still be interesting to replace all the existing crank and shaft generators from Caterpillar and others. They will be a truly disruptive technology there for sure.
