Electromobility

Competence Center for E-Mobility

Since 2013, BMW has been mass producing the i3, its first vehicle which was specifically designed for e-mobility, in Leipzig. The Porsche Panamera S E-Hybrid also rolls off the assembly line in Leipzig. A well-positioned supply industry in the automotive sector and the electrical industry manufactures, for example, powertrain components, batteries as well as power electronics.

Already since 2009 now, the Federal State has been participating as a model region in the federal program “Electric Mobility in Model Regions.” And since 2012, Saxony has been promoting numerous demonstration and pilot projects within the “Showcase Bavaria-Saxony ELECTRIC MOBILITY CONNECTS” program in which e-mobility undergoes practical tests and can be experienced by the public at large.

The Saxony State Ministry for Economic Affairs, Labor, and Transport (SMWA) has assigned the Saxony Energy Agency (SAENA) to establish and operate a competence center for e-mobility. SAENA pools the activities of Saxony’s stakeholders in the e-mobility sector and safeguards the implementation of the Federal Government’s objectives and the Federal State of Saxony’s sustainability strategy.

BMW AG, LEIPZIG PLANT

With its Leipzig Plant, the BMW AG Group has revolutionized automobile production. A distinctive feature of the patented factory layout is the so-called „finger“ or „comb“ structure in the assembly area. Specifically designed building expansions permit material deliveries by trucks to every assembly site in the plant. The integration of new assembly steps is also possible by expanding individual „fingers.“ The plant layout has successfully passed its field test every year since production launch in 2005. Currently, five types of the BMW 1 and 2 model series are all built flexibly on one production line. This is complemented by the BMW i3, Germany’s first mass produced electric vehicle, and the plug-in hybrid sports vehicle BMW i8 which come from a separate assembly line with alternative drive and propulsion technologies and CFRP car body construction.

FES GMBH FAHRZEUG-ENTWICKLUNG SACHSEN, ZWICKAU

The popular development service provider FES GmbH Fahrzeug- Entwicklung Sachsen from Zwickau has translated its excellent performance in the e-mobility sector into a demonstrator vehicle based on an Audi R8 sports car. In cooperation with the Zwickau University of Applied Sciences (WHZ), the company has implemented all elements needed for the development of the complete vehicle which is propelled by four individual motors located near the wheels, ranging from the conceptual design of the electric drive system to the selection and integration of components all the way to the construction and testing of prototypes including the complete engineering of the driving dynamics. 

INTEGRATED DEVICE TECHNOLOGY, INC., DRESDEN BRANCH

In the fall of 2015, the US American electronics group Integrated Device Technology, Inc. acquired the Zentrum Mikroelektronik Dresden AG (ZMDI). Steeped in tradition, the company is a leading global developer of energy-efficient analog and mixed signal semiconductor solutions for the automotive, medical, and consumer goods markets as well as for industrial automation. One of the company’s exemplary products is an intelligent microchip which is able to save energy by systematically monitoring the charging and/or discharging process of lithium-ion batteries; thus, also extending the batteries’ life cycle.

INFINEON TECHNOLOGIES DRESDEN GMBH

The Infineon Technologies Dresden GmbH is one of the largest production sites for innovative automotive semiconductor solutions. Infineon produces in Dresden more than 200 different logic circuits. With about 50 percent, solutions for the automotive industry account for the largest share of the production portfolio. For example, Infineon chips from Dresden can be found inside the BMW i3 from Leipzig. 

Dresden is also the place where the company is currently establishing the world’s first high-volume factory for power semiconductors on 300 mm wafers. Power semiconductors are designed to control and switch high electric currents and voltages which is why they are elementary components in hybrid and electric vehicles. Infineon chips control battery systems in electric cars, recoup their braking energy and, thus, help extend the range of e-vehicles.
