Expertise For The Future For Emission-Free Mobility

The Competence Center For Emission-Free Mobility (KEM) In Mannheim Is Celebrating Its 25th Anniversary – Preparations For The Series Production Of Battery Packs Are Gaining Speed.

  • A quarter of a century of prototypes, small-series production runs and series start-ups of low-emission and emission-free vehicles in Mannheim
  • Series production of battery packs for the eActros and eCitaro benefits from an experienced team
  • Dr. Frank Reintjes, Head of Global Powertrain, E-Mobility and Production Planning at Daimler Truck AG: “At Daimler Trucks & Buses, we are pursuing a sustainable business strategy with the aim of CO2-neutral road transportation. This can only be realized using electric commercial vehicles with a battery or fuel cell drive. We’re constantly developing both of these technologies to series production: we will launch battery-powered trucks onto the market from 2021 onwards, followed by hydrogen drives by the end of the 2020s.”
  • Andreas Moch, Head of the Mercedes-Benz plant in Mannheim: “It’s very important for us to rapidly implement innovations in the production of new drive technologies and to introduce them into series production. And that’s exactly KEM’s area of expertise and competence. Especially in the current transformation of the automotive industry, this is of utmost importance.”
  • Georg Klohr, Head of the Competence Center for Emission-Free Mobility: “In the past twenty-five years, we’ve gained a considerable amount of experience with a variety of technologies. With this knowledge, we are very well positioned for the future. Already today, each Daimler vehicle with an alternative drive system also contains a piece of KEM’s expertise. And that’s something we’re very proud of!”

Anniversary in Mannheim: for twenty-five years, the Competence Center for Emission-Free Mobility (KEM) has been the pilot factory for Daimler AG’s vehicles with alternative drive systems. As a development partner within the company, KEM builds prototypes, produces small series and prepares series start-ups. This closes the gap between vehicle development and large-scale production. Mainly, KEM focuses on introducing and integrating electric and other alternative drive systems into series production. At the same time, designing production lines with cutting-edge technologies is one of KEM’s core competencies. More than 50 engineers, master craftsmen and mechatronics specialists combine their extensive know-how to define new manufacturing processes for components of low-emission and emission-free vehicles such as battery packs or entire battery systems.

Dr. Frank Reintjes, Head of Global Powertrain, E-Mobility and Production Planning at Daimler Truck AG: “At Daimler Trucks & Buses, we are pursuing a sustainable business strategy with the aim of a CO2-neutral form of road transportation. This can only be realized using electric commercial vehicles with a battery or fuel cell drive. We’re constantly developing both of these technologies to series production: We will launch battery-powered trucks onto the market from 2021 onwards, followed by hydrogen drives by the end of the 2020s. But these vehicles will only prevail on the market if they are economically viable for our customers and if the necessary charging infrastructure is available. Here, we especially need our political representatives to put suitable framework conditions in place.”

Series production of battery packs and systems “Made in Mannheim”

The Competence Center for Emission-Free Mobility has already been involved in the series start-up of the fully electric Mercedes-Benz eCitaro city bus, which has been manufactured in Mannheim since the end of 2018. Since then, battery modules have been pre-assembled into battery systems for the eCitaro at KEM. These are mounted to the roof and also installed into the engine compartment during the city bus’s assembly. Due to this expertise, series production of battery packs for the eActros scheduled from 2021 onwards will also take place at KEM.

Daimler will continue to rely on the Competence Center in the future

As part of the future package passed in agreement with the works council in February 2019, an investment volume in the double-digit millions in the Mercedes-Benz site in Mannheim has been announced. KEM, which plays a key role in Daimler Truck AG’s sustainable corporate strategy, also benefits from this. For apart from its twenty-five years of experience, KEM’s new production hall with state-of-the-art equipment is a considerable advantage. In operation since 2016, the 15,000 square meter building houses the necessary equipment for vehicle-specific high-voltage applications as well as facilities for the production of hydrogen tank systems including high-pressure leak testing systems.

“It’s very important for us to rapidly implement innovations in the production of new drive technologies and to introduce them into series production. And that’s exactly KEM’s area of expertise and competence. Especially in the current transformation of the automotive industry, this is of utmost importance,” says Andreas Moch, Head of the Mercedes-Benz plant in Mannheim.

A success story with a secure future – the Competence Center for Emission-Free Mobility

The Competence Center was founded in 1994 for emission-free commercial vehicles and began solely as an experimental workshop for new drive systems. One of its first projects was the assembly of T1-model vehicles – the predecessor of the Sprinter – with electric drives in 1996. Over the past decades, its focus of development as well as production have been diverse and wide-ranging, based on the most recent events and trends. For example, its focus was primarily on natural gas drives in the early 2000s, while it has been shifting more and more to electric drivetrains and battery technologies in the past years. Most recently, KEM has completed the assembly of eActros trucks for customer testing in a team effort with the Mercedes-Benz sites in Wörth and Stuttgart. Among other things, KEM took over the training and qualification of employees with regard to the new technology and its corresponding production processes.

As Georg Klohr, Head of the Competence Center for Emission-Free Mobility, points out regarding the increasing relevance of alternative drives in recent years: “In the past twenty-five years, we’ve gained a considerable amount of experience with a variety of technologies. With this knowledge, we are very well positioned for the future. Already today, each Daimler vehicle with an alternative drive system also contains a piece of KEM’s expertise. And that’s something we’re very proud of!”

Mannheim – a Daimler Truck AG production site that is steeped in tradition

Mercedes-Benz and Mannheim are linked by a very special history. On January 29, 1886, this is where engineer Carl Benz invented the world’s first automobile with the patent number 37435 – the Benz Patent Motor Car. What is now the Mercedes-Benz Mannheim plant was founded in Luzenberg, Mannheim-Waldhof in 1908. Today, the Mannheim site employs more than 8,600 people in the production of engines and corresponding components for commercial vehicles as well as in the production of buses. The plant’s foundry is one of the world’s leading producers of cast-iron vehicle components. Engines are also prepared for commercial vehicles and passenger cars at the “European Center for Reconditioned Engine Production”.

In addition, the plant is the home of the large family of Mercedes-Benz Citaro city buses. From shell construction to final assembly, the Citaro is produced entirely in Mannheim. The Citaro’s flexible production methods cover the entire drivetrain portfolio – from a low-emission combustion engine to variants with hybrid and natural gas drives right up to the fully electric eCitaro. In addition, the Competence Center for Emission-Free Mobility has been accompanying the drivetrains of the future for all vehicle segments from prototype to series production for 25 years. Training and securing new talent are equally important in Mannheim: young people have been training here for more than 100 years; a total of nearly 11,000 since vocational training was first launched.
