Audi a3 e-tron: study with electric drive presented

Ingolstadt, 12. April 2011 – audi has presented a new electric car study based on an a3 sportback. Possible series solutions are to be shown with the compact electric vehicle. A synchronous motor takes over the drive in the a3 e-tron.

Up to 100 kw

The water-cooled e-machine weighs 65 kilograms and has a continuous output of 60 kw. For a short time, for example to overtake, a maximum of 100 kw is available. The maximum torque is 270 nm. The power is transmitted to the front wheels by a single-stage gearbox.

Battery takes up little space

The lithium-ion battery has a capacity of 26.5 kwh and weighs 300 kilograms. The tension amounts to 380 volts. The battery is housed in several blocks under the pack space floor, under the back seat and in the middle tunnel. This division ensures that the loading floor is only about three centimeters high than the production model of the a3 sportback quattro. The posing room of the study summarizes 265 liters, in the series model with front drive there are 350 liters.

Water boiler for the battery

The 30 modules from which the battery is constructed are boiled by water. Thus, the temperature control of the battery is held in the range between 20 to 55 degrees celsius, the temperature in 180 individual cells can be kept at a constant level. Both factors increase the performance: the battery should be able to absorb and output a lot of power over a long period of time.
