BMW predicts different design in electric cars

What about the future of electric cars is still unclear. While many experts worry about the future electric mobility thoughts, BMW is expected that the electric cars in the future will be different visually more vehicles with conventional internal combustion engine drive.

Especially BMW’s CEO Norbert Reithofer is convinced that increasing the external differences, and not only take place only an exchange of the drive assembly is. Reithofer is certain is that the “electric cars will not look like the current car.” This gave the “VDI news” and is thus shows are particularly prevalent on new materials such as composite materials made of carbon fiber reinforced plastics, which are increasingly in body and chassis are used and could thus replace conventional materials such as heavy metal. They help to reduce weight, thus saving fuel and power at.

And BMW is also connected to this trend for the future, says Reithofer. The future of electric cars Bayern should not only drivingly be converted to electric motors, it is, but also include other innovations. In detail, BMW will bring first of next year with the BMW 1 Series with electric drive in a small series of up to 1,000 copies on the market. This small electric car will be used to obtain insights into the practicality of electric vehicles. In 2015, then to the “Mega-City-vehicle” appear as a series vehicle. Thus, the electric drive at BMW is also finding their way. Similarly, one hopes from the testing phase of new factors in increasing the reach of the lithium-ion batteries to achieve. Perhaps a breakthrough is still in this area by numerous developments that have already resulted in forklifts to enormous distances. Experts believe that in theory, batteries with ranges of over 500 miles per battery charge are realistic.

It will be interesting in any case, what developments BMW produces in the coming years.

“Cologne-mobile” Ford Transit BEV sends to the streets

At last it fell, the official start of the electrically-powered Ford Transit. The beginning of the practical phase of the electric mobility project “cologne-mobile” was carried out so now finally, after you’ve filled up the van symbolic. The extensive practice test is designed for analysis of electric mobility in Germany, based on the Cologne area, designed for everyday use and vulnerabilities out. The findings will then serve the development of electric vehicles and the necessary infrastructure.

First, the practical phase the example is made of electrically-powered Ford Transit models, the variant BEV. These are now used as a distribution and delivery vehicles during normal everyday life. As of spring 2011, phase two starts, relying on fifteen other Ford Transit-electric vehicles.

“Cologne-mobile” in the context of the “model Rhein-Ruhr” conducted and sponsored by the Federal Ministry of Transport. A total of 115 million euros, the Ministry has made available, including 7.5 million euros for the project in Cologne.

BMW AG – electric cars from 2013

The Bavarian automaker BMW AG would build according to a report in the magazine “Motor Week” from the year 2013 in Leipzig, the electric car Mega City Vehicles. According to the magazine report, the company has opted for the Saxon work, because it is the most flexible plant within the group and can expand its capacity quickly. The components of Landshut is to provide the carbon parts for the electric city car and be involved in the production.

The lithium-ion battery will deliver probably the joint venture of two technology companies Bosch and Samsung. The electric car production begins two years earlier than originally planned. Currently, a vehicle fleet consisting of 600 vehicles, the electric version of the small car BMW Mini extensively tested. The electric car market is on the rise and almost every car manufacturer has gone into the development of electric cars. The range must be increased, however, and the prices are reduced so that the electric cars can establish not only strong but also prevail.

Sony a (alpha) DSLR-A350 Camera Review, via digitalcamerabattery.us blog

Sony plans to aggressively attack the market with a number of new DSLR SLR cameras is no secret. We had the opportunity to get their hands on the new Alfa 350 and Alfa 200’s again. Here are our first impressions of this very close family, including Sony’s interesting solution to the problem of prolonged exposure time cycle with Live View.

The Sony Alpha A350 offers new technology that makes images faster, easier and more familiar for users of digital SLR cameras for the first time. "According to the press release from Sony.

Note: Most of our findings are also applicable to the Sony Alpha DSLR-A300, also presented at the PMA and is essentially a version of 10-megapixel sensor of the Sony A350, with a lower price.

As for what Sony is promoting the main event of the Sony Alpha DSLR-A350 digital, including;

• Very high resolution 14.2 effective megapixels for beautiful images of the Convention detail, rich tones and bright colors
• Large LCD high-resolution 2.7-inch two-way leveling fire for freedom and comfort at different angles
• Quick AF Live View autofocus quick and accurate and responsive AF performance even with fast moving objects
• Improved in-camera Super SteadyShot to reduce vibration.

The Sony A350 features a new 14.2 megapixel sensor. There is a multiplier of 1.5 x focal length lens is used to obtain the equivalent field of view (FOV) in 35mm terms. Sony Alpha A350 SLR sweet with DT 18-70mm aperture-priority, that large JPEG, the size of 18 mm, 1 / 50 sec at f/5.6, ISO 200, WB Fluorescent central point cut from the lens.

The Alpha DSLR-A350 features a 14.2 megapixel CCD sensor, Live View, a vertical swivel screen, and like all Alpha DSLR-integrated sports anti-shake sensor offset establishments participating in the work aimed to set. It’s just the house or as a kit with the lens Sony DT 18-70mm.

Interestingly, this is not the main sensor, Live View facilities includes, but integrates a secondary sensor in the viewfinder. Sony has broken the traditional Live View systems in the setting of additional sensor in the viewfinder with a tilt mechanism that directs the light is, either through traditional eye. The advantage is not related to the conventional AF in Live View-bypass, so that the autofocus-A350 as fast as you normally would, without interruption or noise.

Making life even more useful view is that a retractable screen can be tilted vertically to allow wide-angle high or low easily. The A350’s screen can not turn the page, or turn on the face, but still a very flexible function.

Like all Alpha DSLRs, the sensor is located on the main platform for moving a mounted adjustable to compensate for camera shake. You do not see the effect on the viewer - or in Live View - but it gets to work with everyone who is going. This not only saves money, it means that you are the stabilization of the lenses that most manufacturers are not suitable as a benefit stabilization system as a standard 50 mm models.

Allegedly, the Chinese-made super capacitor has occupied 60% -70% of market share.

In addition, the country also has several other super-capacitor suppliers, such as the huge volume of new energy companies in Harbin and so on, these companies are setting up the last two years, and in their respective areas of expertise for product development or product marketing. Meanwhile, the domestic Jiangxi, Jiangsu, Henan, Shaanxi and Tianjin and other cities have also introduced policies to support the provinces and enterprises to actively enter the super-capacitor energy storage components such emerging markets such as China, Jiangxi Province, one hundred electronic components electronic letter of the company is also seeking partners to jointly carry out the production of super-capacitors.

In 2005, the total size of China's super-capacitor industry reached 3.9 billion in 2004, 57.2% of 2.48 billion yuan, of which, button supercapacitors 4000 million, convoluted and large super-capacitors is 3.5 million; 2006 Industry total size of 5.7 billion yuan, up 46.2% growth rate, which, button supercapacitor market of 9000 million, convoluted and large super-capacitors of 4.8 billion; the total size of industry in 2007 reached 860 million yuan, increasing Speed up to 50%, of which, button supercapacitor market of 1.4 billion, convoluted and large super-capacitors is 7.2 billion; the total size of 2008 is expected to reach 1.33 billion industry, the growth rate up to 55%, of which , Button-type supercapacitor market reach 210 million yuan, winding type and size of a large super-capacitors of up to 1.12 billion market.

As new companies continue to emerge, supercapacitors are also large-scale application in China is coming. Domestic suppliers are active in different ways to deal with the problems faced by large-scale application.

Improve product safety for suppliers attention. Especially in the high-power applications, a domestic company's top super-capacitors that in security issues, although the super-capacitor internal short circuit can occur, but he pointed out that as long as each is equipped with super-capacitor circuit management system, can be timely identify problems and solve the problem.

Super-capacitors in power applications to overcome the one-time issue of high input costs, domestic suppliers are also active efforts to improve their cost performance. To lead-acid batteries, for example, generally charge and discharge current 5000, but the super capacitor charge and discharge times in theory up to tens of thousands or even hundreds of thousands of times, the actual level, the domestic manufacturers in the technology of super Hai Aowei capacitor can charge and discharge have been 20,000 times. Thus, if the super-capacitor battery service life is 4-5 times the price of its 3 times only, then it can be demonstrated to be more cost-effective competitive advantage.

Better Place electric car developed gas station

The technology company Better Place has developed an innovative gas station for electric cars and in the Japanese city of Yokohama to the public. It is at the gas station for a battery exchange station which allows the rapid exchange of empty batteries, and therefore brings a high level of time savings. The battery change is to last only two minutes and was the prototype of the changing station demonstrates impressive. The battery is automatically changed and means a great deal of time in comparison to the hours of charging power to a power outlet. The changing station has been built on a simple principle. The electric vehicle is traveling on a bridge on the rails there are two sleds. The first carriage is the Swap of the empty battery charge and solve the battery holder. After the battery is moved to a charging station. The second sled at the same time supplies the electric car with a full battery.

Pitching is an area as required for a normal gas station but it is a large stock of adequate size for the charged battery and the recharging required. The concept aims Better Place to an international recognition and success of electric cars. The limited scope could be solved with comprehensive travel and recharge the current vehicles longer distances. The manufacturer has with the countries of Denmark, Israel, California and other states and regions have already agreed partnerships.

In the framework of cooperation to the charging stations are built across the country. The gas station is to purchase their electricity to recharge the batteries from renewable energy sources and therefore has solar panels on the roof. There currently is not known whether the charging system will prevail at all because that it must be accepted by car manufacturers. Up to now the only car company Renault-Nissan as a partner. The automakers hope for a development of current battery technology which the problem of limited coverage is to be solved.

Mennekes relies on electric car market

The medium-sized enterprises Mennekes has worked for a year to develop a system which consists of a charging socket and charger. The system is to combine electric cars with charging stations. By charging electric vehicles can refuel not only with new energy but it is also an accounting of energy consumption. The innovative charging system has already achieved a high degree, as Chancellor Angela Merkel and the CEO of RWE and Daimler could photograph it.

In Berlin and Aachen there Mennekes supported pilot projects launched with the sophisticated innovative Ladesteckersystem. It has been submitted for standardization and will be according to the ideas of the family business into a global standard. The German and European body behind the development of charging system.

Against the Chargers from Israel and Japan have also been submitted for standardization must Mennekes now claim. According to company president Walter Mennekes to the Handelsblatt (Online edition 19.05.2009) system that is superior to the other two loading systems because the charge is four times faster. In the autumn of this year decided that Stromladesystem is to become the world standard. If the Mennekes system enforces this means for the company from the Sauerland a new multimillion dollar market as electric cars in the coming years will grow in importance.
