Converted Audi A2 goes 605 km (378mi) without charging

[Adm]

In a cooperation between Lekker Energie (energy supplier) and DBM Energy (battery producer) a converted Audi A2 drove 605 km or 378 mi from Munich to Berlin without charging. They drove at night on freeways with a speed of max 130 KMH or 81 MPH and an average of 90 KMH or 56 MPH.

The Audi was converted, but fully functional 4 seat car with all options of the ICE version.

I can't read German, but that's pretty amazing. Were there special properties of the A2 that made this possible, or more related to the batteries used by the converter?

Möglich wird die Fahrt durch die von der DMB Energy entwickelte KOLIBRI Technologie. Der intelligente Energiespeicher auf Lithium-Metall-Polymer-Basis ist deutlich leistungsfähiger und leichter als andere Batterien.

This trip was made possible by Kolibri Technology developed by DMB Energy. The intelligent energy storage system based on Lithium polymer is substantially more powerful and lighter than other batteries.

Approximate Translation:

For the first time a forklift equipped with a battery of DBM hummingbird on one battery charge, drove 32 hours and it has 28 hours in regular shifts worked. The operating time is usually from a normal forklift 8 hours.

As to the forklift: I have no clue what kind of batteries are standard there, but the energydensity is not very good. A 24kWh battery weighs 715kg. (48V and 500 Ah, correct me if I am wrong).

If you'd put a "Tesla" battery in a forklift, that would already make a huge difference, but would also increase the price of the forklift substantially.

Not quite sure how they compare the two as there is very little information in their website.

Ok ... impressive new technology. But factual errors too. They claim "Weltrekord" (world record) for distance. Baloney ! 323km=201miles. Tesla Roadster can do that in normal conditions with average drivers daily ! And beat that distance by more than 55% (313 miles not km); admittedly they did NOT do it in an "alltagstauglich" way (daily practical use).

ChargeIT, your quote

Baloney ! 323km=201miles.

was just the stop over. They drove farther to Berlin a 605 km =~ 378 miles in total with 18% left in the batteries.

Although, 90km/h is a bit low for German Autobahn (I guess that why the drove at night, otherwise even trucks would overrun that tiny little A2) the result ist quite impressive. They mention, they used 100kw/h battery... without compromising cargo space or seats.

OOOOPS ! Sorry ! (Where's that red-face-embarrassed emoticon ?) Apparently their article is in dynamic update mode and I was not reading carefully. Apologies, again. (That should not be a upward-smiley on that poor excuse of a redface emoticon.)

100kw/h is a large battery. Looks as if they could have gone ~ 90 additional miles, provided 18% is the actual remaining capacity. Anyone know what the approximate weight of a 100kw/h lithium polymer battery pack would be?

Leaf ~25kWh ~600lbs. So 100kWh ~2400lbs. (Heavy!)
