2015 Audi R8 e-tron battery pack detailed

Audi has released new details about the battery pack installed in the R8 e-tron. While the previous generation model which never actually entered production series had a 49 kWh battery, the new model comes with a much larger 90.2 kWh battery pack. As a consequence, the electric range of the supercar has been boosted from approximately 130 miles to around 280 miles.

Perhaps just as important, the energy density of the new battery has increased from 84 watt-hours per kilogram to 152 watts-hours per kilogram and this improvement has not increased the size of the battery which occupies just about the same space as it did in the first R8 e-tron.

Audi’s engineers were able to keep the compact size by using more powerful individual cells and they squeezed in 7,488 into 52 modules, with each module having 144 cells and tipping the scales at 17 lbs. This new battery pack weighs 1,312 lbs and has more than 10,000 parts and has been installed between the seat and behind it to help the electric supercar achieve a 60:40 weight distribution.

There’s a Combo 2 AC charger which will need 12 hours to fully recharge the battery pack while with a DC fast charger it takes just 95 minutes.
