Seeing things from the customers’ perspective
In addition to the attractive design, Peter Hirschfeld focuses on three other topics that are essential for modern mobility and that have also played a key role in the development of PPE: “People primarily expect a fully electric Audi to have a range suitable for long journeys, high charging performance and, finally, a typical Audi driving experience.” Improvements to the battery and electric motors used in PPE vehicles such as the Audi Q6 e-tron have significantly reduced energy consumption. At the same time, factors such as power density, i.e. kilowatts per kilogramme of vehicle weight, and torque density, i.e. Newton metres per kilogramme, have been significantly increased. “The developers and engineers of PPE basically looked at pretty much every relevant component of an electric vehicle down to the smallest detail and looked for optimisation potential,” explains Hirschfeld. The result: In the new Audi Q6 e-tron, a range of over 620 kilometres is possible.
“But if you’re talking about range in connection with electric vehicles you also have to mention the charging speed in the same breath,” says Hirschfeld. PPE comes with an 800-volt on-board electrical system, enabling the Audi Q6 e-tron to be charged with up to 270 kW. Thanks to the efficient thermal management of the HV battery, this can enable a jump from 10 to 80 per cent in just over 20 minutes at appropriately equipped charging points. “The thermal management system not only cools, but it also preconditions the battery to achieve high charging performance even in cold outside temperatures. Recharging for a range of over 250 kilometres in around ten minutes has thus become realistic in the Audi Q6 e-tron.”
