With its e-tron and e-tron Sportback models, Audi is making electric mobility a reality for long-distance driving - thanks in part to a charging curve that is unique in the competitive environment. Drivers of a fully electric Audi model thus benefit from high charging speeds because the charging capacity of up to 150kW is available for a large portion of the charging procedure. This enables sophisticated thermal management of the lithium-ion battery. In order to assess the everyday usability of an electric car, customers should take not just the nominal maximum charging capacity but also the charging speed into account.

In the current competitive environment, the Audi e-tron takes the lead with a high-performance charging capacity even if there are already models on the market with a nominally higher output.

A high current consumption on the part of the battery for a large portion of the charging procedure is, at the very least, just as important. However, if the car charges with maximum output over a relatively short period and needs to lower its power early, the charging speed is also simultaneously lowered - i.e. battery capacity recharged per unit of time.

Thus, thanks to an ideal charging curve with maximum output available for a long period of time, the charging speed is the more substantial criterion when it comes charging performance and, ultimately, it guarantees a short charging duration at the charging terminal. As well as the average consumption, it also depends on how much range can be recharged on average over a defined period, for example within 10 minutes.
When it comes to the charging curve, the Audi e-tron 55 plays to its conceptual advantages: The curve of an HPC terminal with 150kW output stands out at a high level thanks to its continuity. Under ideal conditions the car charges between 5% and 70% state of charge at the threshold of the maximum output before the intelligent battery management reduces the current.

A major difference from other concepts, which normally only reach their full output for a short time - at the 'peak' - and lower their power considerably before reaching the 70% threshold. On a day-to-day basis, this means an elementary advantage: For a range of around 110km, the customer ideally spends just under 10 minutes at the charging terminal.
The lithium-ion battery of the Audi e-tron 55 has a gross capacity of 95kWh (net 86.5 kWh) and has been designed for a long life cycle. Its elaborate thermal management system forms the basis for well-balanced performance and durability. Liquid cooling ensures that the battery's temperature remains in the optimum range of 25 to 35 degrees Celsius, even at high stress levels or low temperatures.
