Audi is constructing battery-backed charging factors in Neckarsulm | Jobi Cool


Audi is constructing 72 further charging factors for electrical autos at its Neckarsulm web site through the use of so-called cubes, which use used lithium-ion batteries from dismantled Audi check autos to retailer electrical energy.

Two of the cubes feed a complete of 48 charging factors and broaden the charging capability for workers and guests on the Neckarsulm web site within the multi-storey automotive park 1 southeast of the Audi plant. A Dice with an extra 24 charging factors is situated within the automotive park on the north-eastern boundary of the plant. In every of the three cubes, 198 used battery modules with twelve cells every function vitality storage. In line with Audi, the capability will be expanded: there may be room for 132 extra modules in every of the cubes.

By powering the charging factors from second-life batteries, Audi says it could present “advanced set up of a cost-intensive infrastructure with medium-voltage provide strains and transformers.” All three cubes collectively have an vitality content material of 1.58 MWh, i.e. simply over 500 kWh per container dice. Every is charged in a single day with a 70 kW provide line at low grid load, and through the day they ship their electrical energy to an 11 kW charging level.

“Because of the batteries within the cubes, we get 300 kW of charging energy for the wallboxes from a comparatively low linked load of 70 kW,” explains Jannik Mastall, challenge supervisor for increasing the charging infrastructure on the web site. Audi describes the useful as follows: “The system works like a rain barrel. The incoming linked load is constantly fed into the vitality storage models. Sooner or later, photovoltaic modules can present of further inexperienced vitality for Cubes.

Within the multi-storey automotive park on the Audi Discussion board Neckarsulm, 40 charging factors have been in operation for round two years; they’re fed from the grid by way of a transformer station. Along with the brand new Cubes, Audi has put one other 150 charging factors into operation within the multi-storey automotive park 2 on the japanese boundary of the plant – additionally fed by a transformer station. In line with Audi, there are a complete of round 600 charging factors on the plant’s borders in Neckarsulm and Heilbronn, of which round 20 are quick chargers.

“With our charging factors, we make our web site appropriate for the electrification of our fashions and likewise give staff the chance to cost their e-cars throughout working hours,” says Alexander Jakob, Head of Plant Construction Planning Neckarsulm. A number of the charging factors are additionally open to the general public.

Audi already has expertise with battery-supported charging factors, even within the HPC sector: the in-house Audi Charging Hubs additionally use buffer batteries from check autos.
