Mercedes-EQ starts production of battery systems for the new EQS and expands EV expertise



Mercedes-Benz has started producing high-performance batteries for its all-electric luxury EQS at its Stuttgart-Hedelfingen plant, ahead of the sedan's world premiere on April 15, 2021. The EQS marks the start of a new generation of high-performance electric vehicles and will offer a range of more than 700 km (based on WLTP), based on a high-efficiency powertrain and advances in battery energy density. Having integrated battery production seamlessly alongside existing transmission production, the Hedelfingen plant is an integral part of Daimler's global battery production network. The quick ramp-up of its global battery production capacities and targeted expansion of battery competencies through the entire value chain are the key pillars of the Mercedes-Benz electric initiative - from basic research, cell production up to batteries' afterlife, including 2nd-life applications and recycling.


This in-house know-how and vertical integration are critical for playing a leading role in electric vehicles. In addition to scaling up the EQS battery production, the Mercedes-Benz Drive Systems Campus Untertürkheim will specifically expand its research and development activities in the field of e-mobility - through campus for electric and electrified drive systems- as announced earlier this month.


"The roll-out of our electric initiative is accelerating as we pursue CO2-neutrality. Our next all-electric model - the luxury sedan EQS - built on a dedicated electric platform is already in the starting blocks. Therefore, the start of production of its high-performance battery systems in our plant in Stuttgart-Hedelfingen is an important milestone.

As part of the transformation of our company and our products, we are significantly expanding our battery competencies across the entire value chain. Thereby we continue to make efforts to help the next generation of batteries achieve a breakthrough even faster."


Markus Schäfer, Responsible for Daimler Group Research and Mercedes-Benz Cars COO.



The Hedelfingen plant, as part of the Mercedes-Benz Untertürkheim location (Germany), is responsible for the production of battery systems for the Mercedes-Benz EQS, as well as the upcoming EQE. The plant has a production and logistics area of about 16,500 m², relying on state-of-the-art systems, including a wide range of Industry 4.0 technologies. The highly complex lithium-ion battery system is produced on an approximately 300-meter production line with more than 70 production stations and a high number of automated and manual steps. A variety of components, including up to 12 cell modules and the so-called EE-compartment for the intelligent integration of power electronics, make up the EQS battery system.
