Audi CEO: No "Euphoria For Electric Cars"...
We all know that battery packs are the weakest link in electric vehicles. Not only are they heavy and expensive, but they take a long time to recharge and on average can only provide around 100 miles per charge.
A German-based company has changed all that with a new vehicle capable of driving up to 375 miles at moderate highway speeds.
That’s roughly the equivalent of driving from Santa Barbara, CA to the Hoover Dam, without a recharge.
It doesn’t end there. The company responsible for the battery pack, DBM Energy, claims a battery pack efficiency of 97 percent and a recharge time of around 6 minutes when charged from a direct current source.
Unlike the small Daihatsu which was heavily modified by a team in Japan earlier this year that achieved a massive 623 miles on a charge at around 27 mph, the Audi A2 modified by DBM Energy was able to achieve its 375 miles range at an average speed of 55 mph.
In contrast to the Japanese Daihatsu which had just one seat to enable more batteries to be squeezed into its diminutive frame, the DBM A2 retained its four original seats.
At the end of the historic drive, DBM’s CEO Mirko Hannemann, who has been driving the car for around seven hours between the German cities of Munich and Berlin even offered to charge up the cellphones of the waiting journalists with the remaining power left in the car.
Funded as part of a joint venture between German utility company Lekker Energie and the German Economy Ministry, the prototype battery offers a glimpse into the future of the electric car.
Don’t think for a second that this is a one-off battery pack. DBM’s battery technology, called KOLIBRI AlphaPolymer, is already in use in the unglamorous role of warehouses, where forklift trucks running on the same battery pack are capable of 28 hours of continuous operation before recharging is required.
We’re always a little cautious of battery technologies offering ultra-fast recharge and a magnitude of range improvement on other battery chemistry types, but everything we’ve seen and heard from DBM Energy thus far points to a battery technology we’re all keen to watch.
Could this be the future of electric vehicles? Is it ready?
If the battery technology is truly as revolutionary as this impressive journey hints and the battery packs from DBM are ready for the arduous duties of daily abuse at the hands of electric car drivers worldwide it is conceivable that this could be the answer to range anxiety.
Even more, dare we suggest it, the conventional combustion engined car may have met its match.
Only time will tell.
Have an opinion?

The only thing they do seem to have on offer is some book with the information on current battery technology "they don't want you to know" for only €249,- which of course is a real bargain for such forbidden knowledge. I really hope I'm wrong here but is this "record"just some kind of book (or stock?) promotion tour?

if we need cars that go 350 miles on a charge IN ORDER TO SELL CARS, we will have cars that go 350 miles on a charge.
AND NOT BEFORE THEN.

if you and i were designing the ev industry, that is a wonderful conclusion.
however, keep in mind what i previously stated - they will only release what is needed to sell the cars that they can make.
so i dont think you will see that until we have a very mature ev market. the reason being if they came out with one model that could go 400 miles on a charge, everyone would know that the technology exists, and would clamor for it.
at this point, the overwhelming amount of the masses believe that we havent gotten the technology just yet, so they will get the best that is available.
and the bigwigs want to keep it that way, cuz they will get more new cars sales that way. just look at what happens with sales on every other product.
for a long time, the tv standard was a 19 inch screen. then came the 20 inch screen, the 21 inch screen, and so forth. they did not go from the 19 to the 45 in one fell swoop.
you and i would be designing what is best for us consumers. unfortunately, that is not how it works when the bigwigs are in control.
If this can make it's way into production it'd be great news for EV's

German press says, that the batteries take 20 minutes to reload, not 6 min. In fact, the battery-system seems still to be suffering from some security-issues. Not long ago a test vehicle battery (in a forklift) melted down and caused some trouble at the production site (papstar).
Cheers Chris
If this is real, then the end of the ICE age is here.
They are also saying the batter is 97% efficient, which a bit better than current batteries (which are ~94% as I understand it?).
They had ~18% charge left, and since we don't know what the DOD is, a wild ass guess is they used ~90kWh, and this works out to ~240Wh/mile. Which is very plausible, though not outstanding. At 660 pounds, this battery could be used in Dave Cloud's Dolphin and since it is 1,300 pounds lighter, it could get below 100Wh/mile -- and have a range of about 1,000 miles!
*That* would be a revolution!

"Technical Data Audi A2 DBM *
* Subject
Empty weight (including driver) 1260 kg
Perm. Total weight 1600 kg
Battery lithium-iron-polymer (260 Ah/380 V) cell voltage of 3.8 volts
Battery weight about 300 kg
Charging time about 4 hours due to mains phase current in the household (380)
battery requires 6 minutes (future solution)
Life time 2500 charge cycles (without loss of capacity)
= Service life target: 500,000 km
Top speed 160 km / h
5-speed sequential gearbox (race gear: shifting without the clutch)
E-motor 300 Nm torque"
So, the 6 minute charge is future/theoretical limits of the battery. The actual time is 4 hours; which is still very impressive.
Sincerely, Neil

Your cousin driving 200-300 miles per day would obviously be buying a business version EV, like an EV Mercedes Sprinter, and not a consumer version EV, like an EV Toyota RAV4.

Yes, last year you could buy a 19" TV for $500. This year we replaced that model with a 45" TV which runs $175,000. Get them while supplies last.
If there was some breakthrough in battery tech then great. Battery tech has not been improving anything like TVs, cameras, computers, or other consumer electronic devices. Battery improvements are not linear.
Sure, maybe there are interests focused on holding back technology leaps but those leaps will come from discoveries not a simple "let's design the next better model" approach like TVs.

I know it's too early, but it might boost the Leaf acceptance worldwide. Besides, I don't think the japs would like to "stay behind"... ;)

The same goes for this "revolutionary" battery chemistry. I have never heard of lithium metal polymer, simply because lithium IS the metal. This huckster has taken some Kokem li-polymer cells and stuffed them into pack. He put them in a fork truck and neglects to tell us cycle life, temperature range (this really kills lithium batteries) or any other real data. Don't tell me that his website does not need to have information-- this is a component and he should have a data-sheet and tons of data. Please don't think the entire world is incompetent or conspiratorial-- this is is just a criminal and an attention whore, simple as that.
Finally, 350miles at 55mph is not that big a deal. A Nisan Leaf with its 100 mile real-word range will probably get 200 if you drive it at a constant 55mph. It's all about the drive cycle.

Lithium-Metal-Polymer batteries are different from regular lithium-polymer batteries because they have metal-coated anodes, whereas they are carbon-coated in standard lithium-polymer.

EVs without the battery will be cheaper than gas cars, as the basic EV as such is much simpler designed and cheaper to mass-produce. With the battery "leased" from the gas/service station and customers paying the share of the battery amortization (miniscule at 2500 charging cycles....wow), the actual charge and a service fee, we will see a revolution. At $10,000 battery price the amortization (including interest) will be probably in the range of 5-6 bucks, the charge about 2 and the service fee another $1-2. So for about $10 "fuel" costs 375 miles - that will be hard to beat!

Laptop batteries are LiCo. Different chemistries have different characteristics.

Listen i have been investing in alternat energy for 10 years and like my self we are looking to deep and complicated
Not any more the obvious has hit me smack in the face And get this i am of to china to put it together.Don't need loads a batteries either (THINK ABOUT IT )
