Stuttgart. After a construction period of less than 48 months,
Production of the first customer vehicles will begin as scheduled on 9 September 2019. Assembly will take place in a “factory of the future” – flexible, networked and using 4.0 production technology. It is a further step towards the “Zero Impact Factory” with no negative environmental impact: production of the
The construction project included several individual subprojects, each itself with considerable scope. The result was a body shop, a paint shop, a plant for the production of electric motors and components, a vehicle assembly hall and the connecting transport technology. A total of 35,000 tonnes of steel were used for the new production facility – as much as for 140,000

Preparation of the construction work alone required 21 individual preliminary projects and more than 5,000 employee relocations. This also included the excavation pit for the multi-storey assembly building located on a slope: since its height is limited to 38 metres so as not to impair the flow of fresh air to Stuttgart city centre from the north, the pit is 25 metres deep. 240,000 cubic metres of earth were moved for this purpose.
“We’ve built a factory inside a factory – in the middle of the city and close to our neighbours, in the most confined of spaces, in the shortest possible time and without disrupting the existing sports car production facility running at full capacity. Now the factory has been completed on schedule and without any major setbacks,” says Albrecht Reimold. “This was possible due to meticulous planning and an excellent team.” A total of 130 companies and suppliers were part of that team. One of the logistical masterpieces was coordinating the construction site traffic without impairing the significant regular flow at the plant. “Close dialogue with our neighbours was also crucial,” says Reimold. “We kept them fully up-to-date on developments throughout the entire course of the project.”
Some more figures: 10,000 construction site passes were issued, 530 construction site containers and three kilometres of site fencing were erected, and 35 kilometres of site power cables were laid, including power for the 1,000 linear luminaires distributed throughout the construction sites. Four kilometres of new road were also built within the plant.

The specified charging outputs and times (hour/minutes) are dependent on various factors: in general, the charging output and time can vary due to physical and chemical limits, depending on factors such as the available output of the country-specific energy infrastructure, the customer's own domestic installation, the temperature, interior pre-conditioning and charging status, as well as the age of the battery. Charging times may therefore be significantly higher than those specified. To achieve the optimum value of the specified DC charging time (DC = direct current) for a charge status increase from 5 to 80%, a CCS (combined charging system) fast-charging pedestal with > 270kW and > 850V is required, as well as a battery temperature of 30°–35°C. The charging status when commencing charging must not exceed 5%. For physical and chemical reasons, the charging speed decreases as the battery approaches its full capacity. Therefore, it usually makes sense to use fast DC charging to charge the battery up to 80% or up to the required range. The predominant use of CCS fast charging pedestals leads to a long-term increase in charging times. For regular fast DC charging, we recommend a maximum charging output of 50kW. When charging in a domestic environment, AC charging (AC = alternating current) is recommended. Using an (AC) industrial electrical outlet will result in improved efficiency and a much shorter charging time compared to using a household socket.
