Lekker Mobil electric Audi A2 with DBM Energy batteries – Click above for high-res image gallery

Berlin energy supplier Lekker Energie and battery company DBM Energy have teamed up to electrify an Audi A2 and take it on an attention-getting 605 km (379.9 mile) journey from Munich to Berlin, Germany. The run, conducted at night, was such a success that the team is claiming an electric vehicle world record of sorts. While the Japan EV Club managed to squeeze 1,003 km (623 miles) from their Mira on a track driving a steady 40km/h (25 miles per hour), this latest feat was performed on public roads at an average speed of 55 miles per hour. The Germans even had 18 percent of the pack's 115 kWh left at the end.

While the length and speed of the trip are all very nice, the real story here seems to be the batteries that made it possible. Developed sans government investment, the lithium metal polymer (LMP) cells, which Lekker and DBM refer to as Kolibri AlphaPolymer Technology, are said to be lighter and more powerful than traditional cells and operate with an efficiency of 97 percent. They were also compact enough to be integrated into the car without giving up passenger seating or trunk space.

Want more amazing? Apparently, when connected to a generous enough power supply, the batteries can recharge in just six minutes. Also, when asked when production could start, DBM Energy CEO Mirko Hannemann answered, "now." Does it all just sound too good to be true? Maybe, but we expect we'll get more information – and confirmation from other sources one way or the other – real soon.

      Those numbers are astonishing. If they are getting 115kwh of batteries in that small car, the energy density must be unprecedentedly high.
      It works out that they got pretty much bang on 4 miles/kwh, a very believable figure.
      Topping up in six minutes would require a massive 1150kw energy flow though - God knows what the connector would look like.
      I can only imagine that the 97% efficiency figure refers to the SOC, or how much of the battery you can use.
      This is a different order of performance to anything else on the market, or projected for the near future.
        • 4 Years Ago
        They seem to be claiming (DBM) That we already have the battery technology projected for 2015, and hinting that it is opposition in the motor industry, specifically in Germany, which is delaying it.
        Here is a page from the website of DBM, which hopefully will appear as the Google translation:

        @Middle Way. My thought exactly. 6 minutes to charge 100 KWh sounds about as healthy as pumping compressed hydrogen.
        • 4 Years Ago
        It's diverted back to the main page, and in German.
        The bit I am looking at is the link on the top right, which is asking (in German) why batteries aren't better.
        • 4 Years Ago
        To charge it, you just hook up the gigacapacitor, unfold the lightning rod, and wait for lightning to strike.

        That's your charge connector :P

        Goodcheer, it is not the batteries that consume the power, it is the battery management and charging systems that do.

        Charging: Converting 110/220/440v AC to 100-400v DC = some % power loss.
        BMS: Rationing out amps & volts for individual cells/cell packs, bleeding off excess current, etc.

        A battery that never gets unbalanced would reduce the charging losses by eliminating the BMS. Otherwise i don't see how a specific battery chemistry could change the efficiency of charging.
        • 4 Years Ago
        I imagine the 97% efficiency is for every kWh you put in you get out 970 Wh. That's only a little bit better than today's batteries (C-Co for instance is about 94%).

      If this is real, then the end of the ICE age is in sight.

      Lots of people were equally sceptical as well just 10 years ago when A2 claimed 80 MPG... It even performed better. Yes, and ICE engine, but they didn't pick this particular car for the project just liek that. It's so full of efficiency.

      Let's see what happens to the DBM Energy innovation...

      This smells like a scam. If it is, I hope they do some jail time.
      • 4 Years Ago
      this is bigger than people think
      • 4 Years Ago
      It does sound too good to be true, today. I've expected this for a BEV, I even expect twice this range with half the recharge time. BUT, I did not expect it this year. It is bound to happen sooner or later. If this turns out to be less than it appears, it's just a matter of time before this is a true story.

        The catch is 500 cycles.

        Leaf and Volt battery is good for 1,000 deep cycles. That's the limitation of lithium manganese spinel cells but they are cheap (relative). Both Nissan and GM are exploiting it because they are behind in hybrid game.

        The upcoming tri-metal batteries (NMC and NCA) would last 2,000 to 3,000 deep cycles. Both Toyota and Ford will be using tri-metal in their 2012 EVs.

        Like the old saying, good things come to those who wait.
        • 4 Years Ago
        Half the cycle number doesn't matter if range is three times as much. 1.5 times the mileage with same loss. In this case it was over three times Leaf battery range.

      This battery is very badly needed now. The Nissan "Lief" electric car is no longer available as a result of the earth quake in Japan. I was told there's now a 5 year waiting list to get the car. And, the EV1 is also no longer available as a result of General Motors (GM) literally crushing it it out of existence - thank you GM and Mr Wagner, former CEO! By the way Mr Wagner, is the oil cartel sitting on your board of directors? It has raised acute suspicion they are as with other auto manufacturers. And Steven Mark's latest "free energy" Toroid generator,designed earlier by Tesla, that puts out over 17,000 watts of power is not available because he sold out to his attorney and claims his attorney now owns the design. Is there "hush money" involved in this caper? Steven Mark, you have very good taste but how could you lower yourself. As the earth slithers away in pollution from fossil fuels, guys like you were our last hope. Dr Bill Deagle has alot to say and the answer may be found in this amazing interview dated Mar 9, 2011 http://www.youtube.com/watch?v=epboe6B4shE&feature=related

      And here's one more review suggesting the whole thing's a hoax:

        • 4 Years Ago
        Doesn't look like a review, but bunch of people questioning the feat. "Mailbox only company, no one answers the phone, etc." OK, fine. But I can see a minister was there to congratulate them, not the neighborhood cleaning lady. They subsidized it, yeah, of course they will be there to see where the money went, but there's lots of big companies logos on that car - who would put their name at risk just lke that?

        Whatever it is, it gets unreal human resistance, even at EV websites. Let's get more details and talk later when the fact are on the table. This is what will help everyone decide - not speculations and "logical" calculations.
      • 4 Years Ago
      Let me say simply: "Prove it." If Audi could really do this the cars would be on the assembly line tomorrow.

      It's Awesome Riding a Electric Scooter, isn't it? No matter whether you have had the opportunity, Its quite an experience. Its easy and economical too! http://www.electricity4cars.com

      Cool. This is far more detail on this car and its battery than any other news outlet had produced to date. Thanks for the article!
      • 4 Years Ago
      Lots of claims - no details. In one place they say 70% better than lead acid. That isn't all that great.

      I guess EEStor guys are in shock ;-)
