Diseñados como un sistema móvil, los postes permiten cargar y descargar los coches eléctricos. Además se configuran como un punto intermedio entre la electricidad generada por fuentes renovables y su uso en unos vehículos que tampoco contaminarán.
Este proyecto se suma a los que Siemens ya tiene en marcha en materia de ‘E-Movilidad’. La compañía asegura estar trabajando "intensamente" en movilidad eléctrica tanto en su departamento central de investigación, como en materia de energía y los sectores de la industria.

Siemens cooperation with RWE in electric vehicle technology
Erlangen, Germany, 2009-Jul-15
In a kickoff event on July 15 in Berlin, Siemens Energy and RWE announced their cooperation in electric vehicle technology. Siemens is not only participating in the E-Mobility Roadshow but is also a partner in implementing the infrastructure for electric cars. As a mobile electric storage system, electric cars can be both charged as well as discharged and can thus serve as an intermediate storage device for environmentally friendly electric power from renewable energy sources. Equipped with modern control systems, the car thus becomes an integral mobile component of a stable power grid and sustainable power supply.
"Electric vehicle technology will become part of our power supply grid and will increase the fraction of climate-friendly power generation", said Wolfgang Dehen, CEO of the Siemens Energy Sector. “Prerequisite for this is intelligent coordination between power generation, power distribution and electric vehicles. Because the batteries in the electric cars can be charged at variable times, daily and seasonal fluctuating renewable energy can be better exploited. This makes the entire energy system more flexible and environmentally compatible", added Dehen. Over the course of the cooperation with RWE, Siemens will install 40 charging stations for electric vehicles at various plant locations in Germany. The focus will be on Berlin with 20 charging stations. The experience obtained in this pilot project will be integrated in the implementation of a larger infrastructure for charging stations.
Siemens is already active in E-Mobility: both in its central research department (Corporate Technology) as well as in the Energy and Industry sectors, Siemens is working intensively on electric mobility. This entails both the requirements for the actual vehicle and the design of the power grid infrastructure. Areas of research include electric power generation and distribution, traffic and energy management, intelligent electric meters, power electronics, software and sensors as well as the electrical drives and recovery and storage of energy.
As a partner in an international consortium, Siemens is testing innovative possibilities for the integration of electric vehicles in the public power grid in Denmark in the so-called EDISON Project. EDISON stands for "Electric vehicles in a Distributed and Integrated market using Sustainable energy and Open Networks".
As electric drives use energy resources more efficiently than combustion engines due to their high efficiency and as it will also be possible to produce more CO2-free electric power in the future, electric vehicle technology could become an important part of Siemens’ environmental portfolio. In fiscal 2008, revenue from products and solutions of the Siemens environmental portfolio was EUR19 billion, which is approximately a quarter of Siemens total revenues.
RWE presents the future of mobility
RWE has a clear objective: Bringing electricity onto the roads. RWE does not intend to wait until tomorrow, but is already starting today. The establishment of customer-friendly charging stations in various, major German cities will begin this year. With this project, RWE is taking a fundamental step towards climate-friendly mobility to make our cities cleaner and quieter.
Mobile revolution for car drivers
RWE is making e-mobility suitable for daily use. The objective is a universal network of public and private charging stations combined with an innovative billing system for fast, safe and uncomplicated charging. No more detours, charging your car where you would park anyway, whether on a shopping trip, whilst eating in a restaurant or during an evening at the cinema, will be the mobile future.
Today, many people cannot yet imagine that the electric motor will be a solution to the mobile future. Actually, developments surrounding this topic are already in full swing. Battery manufacturers are working on the latest generation of lithium ion batteries with significantly increased ranges. Vehicle manufacturers are poised to begin series production. Politicians are defining the legislative framework required to get the market up and running.
And RWE is also making an important contribution towards the breakthrough of electric cars: RWE is beginning to establish a universal network of charging stations in Germany. In addition to that, RWE is developing appropriate electro-mobility products. Together, all of these components make up an attractive electro-mobility offering for customers.
What is RWE contributing towards the success of the electric car? The answer is electricity. Of course, there can be no electric car without a power supply. Therefore, the electric car cannot get past one of Europe’s largest power suppliers.
As a financially strong supplier, RWE is taking the lead and is investing in technology development and setting up infrastructure. The result will be an attractive charging infrastructure which will meet customers’ requirements in terms of supply security, comfortable operation and invoicing as well as charging times: A vital prerequisite for establishing the electric car as the mode of transportation of the immediate future.
The stage for the demanding but entirely realistic objective has been set: "filling up" with electricity at any time and in any place, including a standardised, customer-friendly payment process.
What will ensure the breakthrough
The basis for the development of the electric car as the means of transportation of the future has been established: High fuel prices and the discussion concerning CO2 emissions gave rise to economic incentives. Innovative battery concepts and plug-in hybrids are already allowing for practical ranges.
The rechargeable battery is taking the lead
Small, efficient and rechargeable: The development of the rechargeable lithium ion battery has opened up new perspectives which were not up for discussion during the "battery age". Whilst the average range provided by batteries today is not yet comparable with that of conventionally powered vehicles, it is already adequate for the daily needs of an electric car in urban traffic. Robust versions for the mass market are anticipated as of 2010, with ranges of between 150 km and 250 km.
Electric cars for all tastes
The automotive industry has recognised the potential of the electric car. Virtually all of the major manufacturers are working on different vehicle concepts – from two-seater urban vehicles and practical family saloons to racy sports cars. Both pure electric cars and hybrid concepts are possible here. The first series production vehicles are anticipated from 2011 onwards. From 2012/2013, customers can look forward to a wide range of attractive vehicles.
The electricity grid as the optimal prerequisite
The electric car has one significant advantage over other drivetrain concepts such as e.g. the hydrogen car: Whilst the necessary charging infrastructure still has to be established, it can access the existing, universal power supply grid. The electric car of the future will actually be able to feed electricity which it does not require back into the grid and therefore relieve strain on power plants. RWE is making a vital contribution in developing this vehicle-to-grid technology.
Comfortable invoicing
"Filling up" with electricity whenever and wherever – a great idea, but how will payment be carried out? RWE is working on innovative offers which use the same tariff at home and on the road, and which besides enabling full cost control give consideration to the desired electricity mix. The key words are flat rates and electricity price guarantee. RWE is making high demands on this development: Invoicing should function as simply as making a call with a mobile phone. In addition, intelligent electricity meters will ensure that the charging current is drawn from the socket at the most inexpensive time.
High efficiency at low cost
Affordable mobility is the prerequisite of positive economic development and personal, individual flexibility. Today, electric cars are still exclusive vehicles for a small group of customers. As unit numbers increase, however, electric cars will soon enable a great deal of mobility at low cost. The lower consumption costs will particularly help in this regard. The electric car therefore has the opportunity to make the transition from an urban car for the few to a daily vehicle for all.
The political support is there
Politicians have long since recognised that investments surrounding the electric car are important and sensible. The demand for cleaner air and climate protection are inevitably drawing attention to the electric car.
The stringent EU fleet emission targets are only the beginning. Already the Federal Government is promoting the purchase of electric cars: According to the German Motor Vehicle Taxation Act*, electric vehicles are exempt from motor vehicle tax for the first five years. Nevertheless, these measures alone are not sufficient to achieve a rapid breakthrough. Further steps are required to accomplish this.
The right basic framework
Financial incentives are required to motivate end customers to purchase electric cars, which are still expensive at present. A one-off bonus on purchasing a vehicle or a CO2-based motor vehicle tax may prove to be sensible tools.
Kick-off investment for the development and the setting up of intelligent charging stations or the designation of pilot regions create incentives for industrial investment. A stable legal and regulatory framework gives companies the necessary security for investments and speeds up the establishment of charging options in the public realm. Specially designated parking and charging zones for electric vehicles would extensively support their market success. The implementation of special road lanes would also be an effective incentive. Finally, uniform technical connection conditions and simple, standardised bases for the charging of grid fees will ensure simple integration into the power distribution grids.
Strong growth as of 2015
Batteries will be suitable for the mass market as of 2010. From 2011, many major manufacturers will start series production of initial electric vehicles. A wider range of vehicles for various customer requirements is anticipated as of 2012/2013, and significantly shorter charging times are likely from 2015 onwards. At the same time, the charging infrastructure will be established – in the major urban centres at first, then in smaller cities as of 2015. Politics will also be flanking this development: The EU is demanding that vehicle manufacturers dramatically reduce fleet emissions by 2020. Otherwise, penalties in the billions are threatened. This target can only be achieved cost efficiently via the use of hybrid technology and electric vehicles.
Vehicle to Grid: Mobile power plants on the way
Climate and environmental protection are the factors which the majority of people spontaneously associate with the use of electric cars. The climate friendliness of an electric vehicle is inseparably linked to the electricity’s source. An electric car which obtains its energy from electricity generated by wind power farms can actually be operated entirely without CO2 emissions.
However, electricity production using renewable sources such as wind is subject to weather-related fluctuations. The result: In the case of strong wind and low current electricity consumption, the renewable energy cannot be used optimally. In contrast, high electricity demand, in which wind energy would be required, sometimes occurs during windless phases.
In the future, electric vehicles may help to compensate these fluctuations. They store renewable energy when it occurs and release it when it is required. They therefore undertake tasks which are already being performed by pumped-storage power plants and help to use the anticipated, higher feed-in capacity sensibly. Power plants are therefore relieved and are able to operate at optimal efficiency. Nonetheless, individual mobility will not suffer. Thanks to innovative solutions which RWE is currently developing in co-operation with international partners from the fields of science and industry, the vehicle will always remain ready for use during this process. A defined minimum energy volume will enable flexible use at any time.
The Electric Mobility Value Chain Takes Shape
1 Energy suppliers integrate all forms of energy, from fossil to renewable, which is why intelligent power grids must be flexible and resilient.
2 An infrastructure consisting of charging stations and invoicing devices is established at public buildings and major parking lots.
3 Batteries in electric cars not only store electricity but return it to the grid if necessary. Internet-enabled cell phones are used to display all the key parameters regarding smart metering.
4 Electricity is traded like stocks, with each electric vehicle driver freely choosing to buy or sell, depending on the current price.
5 The electric car makes it possible to realize new vehicle concepts that include new electronic driver assistance systems that provide added comfort, entertainment, and safety. Service providers can utilize overarching standards to put together and market electric mobility packages. In such a setup, drivers don’t purchase a car, but instead pay for the number of kilometers they travel.
