Audi Shows That Its Fast Charging Curve Makes A Difference

Audi highlights its advantages in fast charging.

By the way of launching its new model, the e-tron Sportback, Audi highlights the charging performance of its electric cars and explains the difference between the charging capacity and the charging speed.

We already know that Audi’s DC fast-charging performances are among the best on the market (see previous reports about the Audi e-tron SUV here and here).

High power over a wide window of state-of-charge (SOC)

One of the most important thing that makes e-tron/e-tron Sportback charging very competitive is a relatively high charging power of up to 150 kW and the ability to charge at a near-peak level over a large portion of the charging procedure.

According to Audi, in ideal conditions, 150 kW output is possible between 5% and 70% state-of-charge (SOC).

Audi notes that the ability to stick at the peak output is unique in the competitive environment and shows a charging chart with another curve of fast charging “competitors” electric cars (with higher peak power, but only for a narrow SOC window). We could obviously find a similarity between this curve and Tesla’s charging curve.

“Therefore, many customers orient themselves toward the maximum charging capacity of their electric car to assess the charging characteristics – but this value is of only limited use if it concerns quick refueling of range at a fast charging terminal. High charging speed (kWh / minute recharged) over the entire charging process is essential for a short charging duration. In other words, a high charging capacity must be available for as long a period as possible. The e-tron models with their continuous output impress with precisely this property.”
