Worldwide electric initiative: Mercedes-Benz is putting the first EQ model into series production

Production of the EQC (combined power consumption: 20.8 - 19.7 kWh/100 km; combined CO2 emissions: 0 g/km)[34] started on 6 May 2019 at the Mercedes‑Benz plant in Bremen. The new EQC as a fully electric vehicle will be highly flexibly integrated into ongoing series production. The high Mercedes‑Benz production standards therefore ensure top quality across all vehicle models. In parallel with this, production of batteries for the EQC is coming on stream at the expanded battery plant in Kamenz (near Dresden).

The first EQC will roll off the production line at the Mercedes-Benz plant in Bremen. There it is being produced on the same line as the C-Class Saloon and Estate as well as the GLC and GLC Coupé – digitally, flexibly and sustainably. Production of vehicles with various drive systems can be adapted variably and efficiently in line with market demand. This approach is an ideal way to ensure the best possible use of capacity at the plant, and guarantee high Mercedes-Benz production and quality standards.

Digital solutions such as sophisticated mobile devices, driverless transport systems and the 'paperless factory' assist the assembly team. Production staff are irreplaceable, even in the age of electric mobility. The use of Big Data and artificial intelligence assists with predictive maintenance, for example. This means the fact that the company made investments in maximum flexibility and hi-tech equipment offering trend-setting Industry 4.0 solutions at an early stage is paying off.

Unique: The "double marriage"

When the body, suspension and powertrain come together in automobile assembly, this is referred to as the "marriage" – in the case of the EQC this is when the two powerpacks are installed in the body. One major innovation is the so-called battery joining centre. The second "marriage" takes place here: This is where the EQCs are recognised as electric models with the help of data tags attached to the body, and equipped with a battery. The body is suspended from a carrier and deposited on a frame. Support arms raise the battery to the vehicle's floor from below. An employee monitors the automatic bolting in place.

Global production network and battery production network

Alongside Bremen, the Sino-German production joint venture Beijing Benz Automotive Co. Ltd. (BBAC) will start production of the EQC this year – for the local market in China. As it does for the C-Class and the GLC, Bremen acts as the centre of competence for production of the EQC in other locations. BBAC is part of the global production network of Mercedes-Benz Cars. Other production locations for future Mercedes-Benz EQ models are the Mercedes-Benz plants in Rastatt (Germany), Sindelfingen (Germany), Tuscaloosa (USA) and Hambach (France).

The batteries for EQC production in Bremen are produced by wholly owned Daimler subsidiary Accumotive at its site in Kamenz (near Dresden) and delivered partly charged. These batteries are kept near the production line and then delivered to the line flexibly on demand using driverless transport systems. Local battery production is a major success factor in the electric initiative of Mercedes-Benz Cars. The production network for the mobility of the future is well positioned.

All in all, the company will be investing over one billion euros in global battery production with two factories each in Kamenz/Saxony and Stuttgart-Untertürkheim (Germany), and one each in Sindelfingen (Germany), Beijing (China), Tuscaloosa (USA), Jawor (Poland) and Bangkok (Thailand). In future the worldwide battery production network of Mercedes-Benz Cars will consist of nine plants on three continents.
