10.5.2019. Audi with the e-tron electric mobility suitable for long distances – thanks to a competitive environment, unique charging power. The e-tron is not only the first production car that can refuel at a fast-charging station with up to 150 kW of electricity.
The high charging power over a wide range of charging sets standards and reduces downtime. The sophisticated thermal management of the battery delivers performance in cold as in hot outside temperatures.
Most of the load operations can take place at home or in the workplace – the factor of time plays in General, not a big role, because the car is parked for a long time. By contrast, counts on the length of each Minute range and quick Charging is essential, for example, in the case of a business trip. After a short Pause, the car should be ready for the next stage. This important basic requirement for an electric car have implemented the Audi engineers in the development of the Audi e-tron consistently.

Convincing: the load curve
In the current competitive environment, the charging performance of the Audi e-tron standards – and not just because of the ability of the HPC-fast charging (High Power Charging) up to 150 kW. At least as important as the maximum power, a high current consumption of the battery over a wide area of the charging process.
The 150 kW-load curve of the Audi e-tron is characterized by the continuity at a high level: The car loads in ideal conditions in the range of 5 to 70 percent state of charge at the threshold of the maximum power, before the smart battery management lowers the currents to the Lithium-ion-ensure cells to spare and your life. This is a big difference from other concepts, which will reach its full power only for a short time (Peak) and prior to the 70% threshold is significantly down rules. Because the Audi e-tron is loading at 80 percent, with more than 100 kW.
In everyday life this means that a fundamental value-in-use For about 100 km range, the customer is in the ideal case, less than 10 minutes at the charging station. The 80 per cent mark, the Audi e-tron achieved in less than 30 minutes. Although for technical reasons it is significantly more time consuming, with the remaining 20 percent of a Lithium-ion complete battery takes the full load of the Audi e-tron on a HPC-pillar-less than 50 minutes – an outstanding property in a competitive environment.
Thought: the thermal management
The Lithium-ion battery of the Audi e-tron has a nominal capacity of 95 kWh, and is designed for a long service life. Your elaborate thermal management lays the Foundation for a balanced Performance. A liquid cooling ensures that the battery temperature is also at a high load, or low temperatures in the optimum range of 25 to 35 degrees Celsius. This technical design ensures a high Load – and driving performance and at the same time prevents excessive stress on the cells. At the heart of the cooling system are rust – extruded profiles – visually comparable to a latte which are glued from the bottom to the battery system. A newly developed, heat-conductive adhesive connecting the cooling unit with the battery housing. The contact between the housing and placed in the cell modules, the so-called Gap-Filler restores, in turn, a heat conductive Gel that fills each cell module between the space of the housing. The resulting waste heat of the cells directs are going to evenly over the battery housing in the coolant – a particularly effective solution. The spatial separation of the cooling water leading element and the battery cells, therefore, increases the security of the overall system.
Holistic: the load offer
In addition to charging power and battery capacity, the availability of charging stations is a key factor for unlimited and worry-free electric mobility. So in terms of infrastructure Audi has left nothing to chance. The private load service, the e-tron Charging Service, the brand with the Four rings is currently around 100,000 charging points in 17 EU countries, by card or Smartphone. Country-specific standardized Council allow for simple and worry-free trips without the hassle of price comparisons. On longer rides, the Audi invite customers to special terms and conditions of the HPC pillar of the IONITY network is gradually expanded and in the year 2020 of more than 400 stations. More HPC-load of points from well-known suppliers complete the offer of the e-tron Charging Service along the long-distance, and create additional flexibility.
