Audi: The e-tron is the class loading champion
EVERY MINUTE COUNTS Audi also wants to achieve long-distance capability with the charging power of the e-tron, which can be driven purely electrically. The e-tron is the first production car that can draw up to 150 kW of electricity. The high charging power over a wide range of the charging process shortens refueling times because the battery's thermal management ensures performance in both cold and hot outside temperatures [...]
The high charging power over a wide range of the charging process shortens refueling times because the battery's thermal management ensures performance in both cold and hot outside temperatures.
It is true that most charging takes place at home or at work, where the time factor does not usually play a major role. On the long haul, however, every minute counts. After a break that is as short as possible, the car should be ready for the next leg.
Battery management lowers currents
At least as important as maximum power in an all-electric vehicle is high battery current consumption over a wide range of the charging process. Under ideal conditions, the car charges in the range of five to 70 percent state of charge at the threshold of maximum power before the battery management system reduces the currents.
That's a big difference from other concepts, which usually only reach their full power for a short time and already reduce it significantly before the 70 percent threshold. The e-tron still charges with over 100 kW at 80 percent.
Only a short stay at the charging station
In everyday life, this means elementary utility: Ideally, the customer needs less than ten minutes at the charging station for a range of around 100 kilometers. The e-tron reaches the 80 percent mark after just under 30 minutes. Although for technical reasons it takes significantly more time to fill the remaining 20 percent of a lithium-ion battery, full charging at an HPC station takes less than 50 minutes.
