Audi charging hub in Zurich
0A heart made of second-life batteries
The heart of the Audi charging hub is made of charging cubes – modular containers that, in addition to a quick-charging infrastructure, contain used lithium-ion batteries created from disassembled Audi test vehicles. Martin Wosnitza, Head of Business Innovation and the Audi project leader for the Audi charging hub in Switzerland, explains: “The second-life batteries serve as buffer storage, the advantage of which is the fact that we don’t need an elaborate, expensive infrastructure with a high-voltage grid and transformers. The hub only requires minor power demands from the local power grid. The Audi charging hub is in a position to bring a sustainable quick-charging infrastructure with second-life battery storage to all the places where the power grid would prove insufficient.”
Recharging for man and machine
At the site in Zurich, there are a total of four covered high-power charging (HPC) points with up to 320 kW. Its storage capacity amounts to 1.05 MWh – comparable to the storage capacity of 11 Audi e-tron 55s – and it can supply power for up to 60 electric vehicles per day. The hub also uses 100-percent renewable energy, while a photovoltaic system on the roof over the charging cubes supplies additional green energy.
Thanks to its modular system, the hub requires little space, can be individually adapted to its surroundings, and it be dismantled later on – in short, it’s a tailor-made quick-charging solution for urban locations. The charging hubs are available in a variety of sizes without much preliminary work or elaborate construction. This flexibility allowed the Audi charging hub in Zurich to forgo a lounge, because the immediate vicinity has a wide range of services. Two large 55-inch screens provide essential information, in addition to tips about maximising your charge.
A crucial component of this variable, compact concept is the swivel arm that’s a modified version of the one at the pilot location in Nuremberg. With this, cars can be charged across the entire width of the space with exceptional accessibility – regardless of where the manufacturer put the charging port. The operating displays at the charging points are height-adjustable, and the areas between the charging cubes and vehicles are wide enough for wheelchair users.
Charging slots booked via app
Audi customers can use the myAudi app to book an individual charging slot in advance for 45 minutes at no extra cost. Reservations are available for the first 15 minutes, after which they’ll be canceled. The Audi charging hub can be used by all brands of electric vehicles that are equipped with a CCS charging port, which is common in Europe.
Outstanding innovation
For the premium brand with the four rings, the Audi charging hub marks another step in its evolution toward sustainable and individualized mobility, and it has also been presented with international accolades.
Head of Marketing Katharina Momani proudly said: “The innovative Audi charging hub in Nuremberg was presented with the renowed Red Dot Award in 2022 in the ‘Brands & Communication Design’ category, and it also won the ABC Best of Best Award in 2022 in the ‘Mobility & Innovation’ category. We’re convinced that we’ll continue this success with the refined concept in Zurich.”
