Firms, said to through this technology competition, in order to achieve the German leading position in the field of electric vehicles provided new impetus.

The German government has asked the related companies and research institutions at the German aerospace centre within a time limit to submit project proposal.

The necessity of the technical competition analysis

Germany's economy and technology, according to research work for electric car motor drive system of electric will lead to the whole value chain of automobile profound change. This not only affect the automobile and parts industry, and will be radiation to the energy industry, information technology industry and other fields. Judging from the current, electric cars, to a great extent, is based on the identity of the internal combustion engine car intervention to the current traffic environment, and transportation facilities and energy network together. But, on the one hand, the future of electric vehicles need to have new functions and characteristics, which requires to form new, on the basis of information and communication technologies car environment architecture. On the other hand, the electric car will be through the corresponding interface connected to the power supply system, used as a mobile energy storage, the active management energy application. In addition, electric cars are expected to become a part of intelligent transportation system, and the contact between traffic participants also become more closely. Contact information and communication technology as essential elements of the three stages of development, plays a key role.

Germany's economy and technology through technology competition "the meaning of information and communication technology for electric cars Ⅱ", promote the research and demonstration project, in order to accelerate and extensive use of united, on the basis of the information and communications technology electric car development program. Launched in November 2010, the ICT strategy "number 2015 in Germany, the German government on specific advice, technical competition" the meaning of information and communication technology for electric cars Ⅱ "will focus on developing the key elements of the strategy of" digital Germany 2015 ". At the same time, competition also belongs to the technology introduced in August 2009, Germany's part of the "national electric vehicle development plan", "national electric vehicle development plan" to form the framework of the electric vehicle technology development and market development. In May 2010, the German chancellor Angela merkel's suggestion, the established the "national electric vehicle platform", as an interdisciplinary cooperation institutional platform.

Technology competition goal setting

Technology competition "the meaning of information and communication technology for electric cars Ⅱ" has established the following strategic objectives:

* establish German technology and industrial status

* the car into the grid

* to form new transportation on the basis of the information and communication technologies

From the point of specific objectives, technical competition focus on "smart car", "smart grid", "intelligent transportation" three big plate.

1, the smart car (development based on new information and communication technology of smart cars)

Information and communication technology such as electricity, electronics and software is vital for promoting the international competitiveness of German car industry. Information and communications products in the automotive manufacturing in the modern passenger cars accounted for 30-40% of the value chain, is the driving force for the reform of car. 90% of vehicle engineering innovation is done through the information communication system. Today, ABS, electronic fuel injection, electrostatic precipitators, adaptive cruise control, parking assistant, emergency brake assist system such as the basic functions are completed by information and communication technologies. As the "nervous system" of modern new type of car, information and communication technologies have played an important role in integration and optimization to the car.

For the future of electric cars, new information and communication technology is indispensable, reason is mainly manifested in the following several aspects:

* reduce vehicle weight and travel distance increase

At present, the safety performance of cars mostly rely on passive safety measures, such as airbags, crumple zones), rather than relying on information and communication technologies. Initiative, proactive, intelligent security measures (e.g., emergency brake assist system, automatic spacing) through the prevention of accidents, can better instead of passive protection measures, and can reduce the weight of the electric car, increase the travel distance of the vehicle.

* reduce the cost and complexity

By setting several concentration or dispersion of networked computing devices, reduce the number of vehicles scattered in the special control device. These devices through the communication between intelligent actuators and sensors interface connected to the Internet. With the help of a simple and flexible information communication system, the whole process becomes easy to control.

* to implement the new functions of the car, enhance the adaptability

The batteries of electric cars cost is higher, when compete with conventional cars must be able to reflect the value of it, and its value-added points mainly embodies in improving the comfort and safety, provide new entertainment function. So, should focus on enhancing the software modular.

In a word, "smart car" research and development goal is to "smart" car development, test more simple information communication system, a new type of drive system to realize to that of the electric car.

2, a smart grid (realizes the electric vehicle and energy supply systems of intelligent networking)

In the future, intelligent cars must be implemented with the close interaction between energy network, in order to improve the stability of power grid, make full use of renewable energy potential. The technology competition is one of the goals of reasonable regulation and control electric vehicle charging, avoid branch power grid in power load. In addition, with the aid of intelligent control system, electric vehicles can be used as a backup power and mobile storage in the future, the electricity charge less time, at the time of peak power feedback to grid, have the effect of peak peel.

"Smart grid" development goal is, through the development based on ICT energy facilities and electric cars, realizes the dispersivity of the renewable energy generation and the electric car (used as a mobile energy storage) between the integration of complementary.

3, intelligent transportation, development of intelligent transportation facilities, improve efficiency, mileage, and security)

Electric vehicles and traffic facilities are closely in the future. Electric cars compared with the traditional vehicle, although has the advantage of saving energy, but in limited driving distance, length of time of charging cycles, charge, as well as disadvantages. So, in the case of travel distance electric vehicle co., LTD, need to develop new type of traffic patterns. In addition, the future of the electric car will have more advanced than traditional internal combustion engine car remote information processing technology and navigation technology, to optimize the driving path, promote the communication between traffic participants. Such, traffic congestion, reduce traffic safety conditions improve, the entire traffic conditions improved. In a word, "intelligent transportation" will focus on infrastructure, traffic management, in the process of the car and the car intelligent connection. The navigation function, based on ICT can make electric vehicles and transportation infrastructure to realize the total integration.
