Hello folks,

IF this is real, then this is the beginning of the end of the ICE age.

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.

Here's a translated link to a related article, about the inventor and a picture of one of the cells:

100kWh in just 300kg is pretty amazing! I wonder what it costs.
