| Many visitors tested electric vehicles on a dedicated route. |
For the first time under a negative sign was this year's convention and trade show "Elektromobilia", May 22 - 23 February at the Cologne exhibition center was held. Short oppressed press reports on the mood of the 800 participants, according to the intended promotion of electric mobility could turn from public funds significantly lower than previously planned. Then in the will of "the government program for Electric Mobility" for the years 2012 and 2013 provided for one billion euros missing up to 400 million euros. Whether on this basis, the promotion can take place three to five "windows electric mobility" in the planned scope of 180 million euros, is at least questioned.

For the organizers of the "Elektromobilia", the Central Association of the Electrical and Electronics Industry Association (ZVEI) and Koelnmesse GmbH, thus became at least the structural approach to recommend the Rhine-Ruhr region as a leading model regions for one of the eligible showcase for electric vehicles, in a new light. However reiterated Harry K. Voigtsberger, Minister of Economy, Energy, Construction, Housing and Transport of North Rhine-Westphalia, the ambitious goal of bringing up to 2020 more than 250,000 electric vehicles in NRW alone on the road. In addition, centers of excellence in the areas of storage technology, infrastructure and vehicles occur.
Friedhelm Loh, President of ZVEI and Chairman of the Friedhelm Loh Group, called on the federal government's support in the planned order "now actually provide." Basically focused on long-term eligibility of electric mobility at the participants and speakers of the two-day event is not seriously questioned. Finally, the windows were just "a huge success," said Dr. Klaus Mittelbach, CEO of ZVEI, as part of a panel discussion. Prof. Dr. Herbert Kohler, Vice President e-drive & Future Mobility at Daimler AG, praised the "very balanced funding environment." The standardization roadmap that Germany needs "urgent" come, currently progressing well.

Still in the exploration phase
Numerous speakers dampened the high expectations of rapid technological advances, and also referred to the long history of the thermal actuators. Electric mobility is "still not well understood," Enno Fuchs, electric mobility stressed at Opel. All manufacturers were in a dilemma, the innovative technologies on the vehicle, the more costly it would be. This dilemma was solved, "or we will not see electric vehicles as a mass phenomenon," says Fuchs.
"In a very exploratory stage," sees Dr. Stefan Kampmann, Executive Vice President of Gasoline Systems, Electric Vehicle and Hybrid Systems, Robert Bosch GmbH, the electrical mobility. In the medium term, the focus should not be on the number of electric vehicles, but on how many kilometers are driven electrically actually. For this period, the PHEV (plug-in hybrid) is the right solution, which is based on an existing vehicle architecture. The actual economic key for the introduction of electric vehicles, however, lies in the battery, so Kampmann. By 2020, Bosch expects a reduction in battery costs in half from today's levels. The battery weight is to be reduced from an average of 300 kg to 120 kg.
Battery technology in focus
The topic of battery technology and charging infrastructure took a wide space of the event. Principle was the "direct path to the battery technology without intermediate solution with hydrogen the right one", said Prof. Dr. Burkhard Göschel, CTO Magna International. Former BMW board emphasized, however the success of emotionality: "If we restrict the integration of electric vehicles into the infrastructure systems that freedom, we will have no incentive to buy."
Stefan Suckow, managing director of Johnson Controls (JC), provides the lithium-ion technology as an "enabler" and he referred to the apparent limits. Today's standard energy density of 120 Wh / kg to a maximum leave to 240 Wh / kg increase. He sees potential in open battery systems that absorb oxygen from the air, for example, during your cruise.
Inductive Charging
Even Daimler manager Kohler expressed doubts "whether we can ever achieve energy densities above 200 watts." Basically everything in the battery technology was "welcome what does a customer-friendly." Therefore, the inductive charging is still "the future", but "a great perspective." The Stuttgart company take care of themselves so "intense about".

The operators, however, prefer the normal shop opposite the fast charging. Dr. Norbert Verweyen, CEO RWE Efficiency GmbH acknowledged in Cologne also with the "Mar" on that technology for inductive charging virtually "disappears into the earth." Much more important is the cross-border interoperability, the "global standards for the charging infrastructure, with clear interface definitions" requires.
Not afraid of China
No worries the experts of the competition from the Far East. After a "buzz around the issue of e-mobility about three years ago," it was also in China "calmer" stated Andreas Matthé, at its own six years of practical experience in China, now CEO of the BU Low Voltage Siemens Division Low and Medium Voltage. Meanwhile, the "Chinese also recognize where they are really" have. Stefan Suckow, JC, was also a little worried. China was also in the battery area "no big advantage." However, China operative build the charging infrastructure on the structural advantage, at least in the less developed regions still without costly conversions directly to implement the necessary equipment for electric vehicles, said Peter Gresch, Director of Development of the Brose GmbH & Co. KG.
Dr. Ulrich Eichhorn, Director of Technology and the Environment of the Association of the Automotive Industry (VDA), recommended the transfer of good recipes for success in the German automotive industry: "We are so successful because we pervade everything in depth. . We want to make the same electric mobility "Whether or not, however, the strategy of" first mover "or" fast follower "promises greater success remained open:" You have to develop each its own strategy. In our industry, this is totally normal. "
