New Delhi: Mercedes-Benz has started producing batteries for its all-electric luxury sedan EQS at the Stuttgart-Hedelfingen plant in Germany, ahead of its world premiere on April 15, 2021.

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), the company said in a statement.

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. The EE-compartment is assembled by the Mercedes-Benz Berlin site.

The EQS will be equipped with battery layouts enabling different range and performance variants. With an installed energy content of up to 108 kWh, the EQS targets, according to WLTP a range of more than 700 km.

The in-house-developed software technologically enables updates over the air (OTA), ensuring that the energy management of the EQS will remain up-to-date over the entire lifetime of the vehicle. Besides its CO2-neutrally produced cells, the EQS battery cell chemistry includes nickel, cobalt and manganese in a ratio of 8: 1: 1, cutting the cobalt content to around ten percent.

“Our next all-electric model – the luxury sedan EQS – built on a dedicated electric platform is already in the starting blocks. The start of production of its high-performance battery systems in our plant in Stuttgart-Hedelfingen is, therefore, an important milestone”, Markus Schäfer, member of the board of management of Daimler AG and Mercedes-Benz AG, responsible for Daimler Group Research and Mercedes-Benz Cars COO, said.

“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,” he added.

EQS is produced alongside the new S-Class at Factory 56 in the Sindelfingen plant, which operates CO2-neutrally from the beginning. As early as 2022, the company’s own Mercedes-Benz passenger car and van plants worldwide including the Hedelfingen plant will operate CO2-neutrally, the company statement said.

Expansion of in-house EV expertise focusing on battery cells

In order to deepen its competence as a centre for battery technology, a new factory for the small-series production of future lithium-ion battery cells is being planned, starting its operations in 2023.

The company said the sustainability factor, transparent cell development through to recyclability, plays a major role in this. Mercedes-Benz plans to invest a three-digit million amount in the transformation of the site.

The German auto giant further added that it is strengthening its expertise in the field of e-mobility. Research and development activities such as the e-technology center and cell technology center, where, among other things, prototypes for the electric drive system are built and cell technologies are researched and tested at the Untertürkheim site (Germany).
