Audi pilots concept for quick EV charging


Audi is developing a modular hub providing quick charging for six electric vehicles (EVs) along with a lounge area for drivers.

The hub is formed out of flexible container cubes housing the charging pillars along with second life lithium-ion batteries from disassembled development vehicles for energy storage.

With this interim storage of roughly 2.45MWh, the six charging stations, which have a charging output of up to 300kW, only need a standard 400V high voltage hook-up, according to Audi.

That makes output starting at 11kW per cube sufficient to be able to fill the three storage modules with a total capacity of 2.45MWh continually and to charge them overnight.

Solar PV modules on the roof provide additional green energy, which also is expected to reduce planning times and costs as making the selection of locations easier.

The modular concept also provides flexibility and scalability and the hub transported, installed and adapted to individual location quickly, largely independent of local network capacities.

“The charging hub embodies our aspiration for the electric era and highlights Audi’s commitment to ‘Vorsprung durch Technik’ (Lead with technology),” says Oliver Hoffmann, Member of the Board for Technical Development of Audi AG.

“A flexible high power charging park like this does not require much from the local electricity grid and uses a sustainable battery concept.”

With the charge time of vehicles approaching that of a coffee break, the charging hub includes an upstairs lounge area for drivers. For example, the Audi e-tron GT is able to charge enough energy for up to 100km in about five minutes, with a charge from 5 to 80% taking roughly 23 minutes under ideal conditions.

Audi also propose offering exclusive reservations for what it calls a premium emobility experience.

Audi is currently identifying a location and partners in Germany to pilot the charging hub, with the intention to put it into operation in the second half of the year. Findings on day-to-day operations and customer acceptance will be fed into further implementation of the concept.

Audi expects to have more than 20 fully electric models available by 2025 and for the first time in 2021 more than half of the newly introduced models are electrified.
