power electronics, require intelligent, matched processes that
must be developed with regard to possible large-scale production.
Here in particular, efforts must succeed in establishing competen-
cies (not only in the development area) that are already available
in the state, such as in railway and rail technology, accessible and
usable for new applications of electromobile vehicle concepts.
The manufacturing of complex transmissions, as used in parallel
hybrid or power-split hybrid vehicles, can also be viewed as a ca-
pacity of the German automobile industry and of the manufactu-
rers in the „Ländle“ (e. g. ZF Friedrichshafen AG, Getrag GmbH,
Cie KG, LuK GmbH), for the future market of electromobility. In this
regard, the development tasks that must be performed in the area
of automation and increasing the transmission ratio spread or the
number of gears form the focus. From this perspective in parti-
cular, a transfer of the new concepts into series production must
be viewed as a great challenge for the next few years [Automobil
Produktion (2011b)].
Numerous studies still forecast, from the short-term or medium-
term perspective, a high share for the combustion engine as the
essential propulsion component [for example, see Dietz (2010);
Frost & Sullivan (2010); Roland Berger (2011b)]. Thus, starting
from current estimates, due to the parallel development of diffe-
rent propulsion concepts the question arises as to the extent to
which synergies in the various drivetrains are present and as to
the extent to which integration of processes required for manufac-
turing in the existing aggregate plants can occur smoothly. Here,
in particular, efficient manufacturing procedures and factory plan-
ning concepts must be developed that enable industrialization of
electromobility from the technical production perspective [Lanza
2011b)]. Since in the next few years there will still be extremely
low quantities in the electric vehicles sector, it will be difficult to
achieve effects of scale. Approaches, such as product develop-
ments that are appropriate for manufacturing and installation, as
well as cost-optimized innovations in process design, must move
further into the foreground [ATZproduktion (2011)]. If existing ve-
hicle concepts will no longer just be „modified“ in the future, (see
conversion vs. purpose design), but will be fundamentally redesi-
gned, then factors such as weight, insulation, and lighting in ve-
hicles must be re-evaluated. Use of materials that formerly were
unknown is conceivable in this respect. Large-scale use of CFRP
in series production of structural components, as is already the
case in aircraft construction, may already be conceivable in the
foreseeable future. The effects on production would be enormous.
China has classified electromobility as a sector to be promoted.
In addition, the country can rely on years of experience in manu-
facturing lithium-ion batteries in the consumer sector. The extent
to which this could pose intense competition for the Baden-Würt-
temberg automobile industry will become evident in the foresee-
able future, since development directions in this quite new appli-
cation field of electromobility have not yet been fully tapped.
In addition, it should be noted that the spread of battery quality is
still quite high, which makes a new realignment of production ne-
cessary. Moreover, safety requirements in the production of batte-
ries impose additional challenges that must first be solved through
innovative approaches from the technical production perspective,
on the way to economical production.
»In order to establish a leading market presence for electro-
mobility in Germany and Baden-Württemberg, and in order to
further pursue the goal of ‚leading provider‘ the establishment of
production of powerful, cost-effective and simultaneously safe
batteries in the state, is required. Particularly for cell production,
there is an enormous catch-up requirement compared to Asia.
The number of patent applications is one indicator in this regard.
At the Chinese Patent Office, the number of patents applications
in the field of battery technology exceeds the number of patent
applications for this field in Germany, several times over.«

»In Germany, and particularly in Baden-Württemberg, we have
an outstanding starting position, if we are successful in trans-
ferring our existing competencies in the area of train and rail-
way technology to the automotive world.«
