an Audi A2 modified by the electric car in the middle of the case without charge drove from Munich, Berlin, 605 km of driving distance to look forward to bring the electric car a great surprise. German Federal Minister of Economic Affairs Bruderle commend this was a world record event, the electric car “breakthrough” and said “do now is, will this ‘Berlin manufacturers’ performance hit caused by the great achievement of a world . “
electric car step forward,
electric car if only to see a single charge mileage, Germany, 605 kilometers of driving distance this far less than electric vehicles in Japan in May this year, the club achieved continuous driving a single charge 1003.18 km world record. However, tests used in Japan is not suitable for “normal driving” the electric car is different from the German trial of electric vehicles and conventional vehicles is almost almost the same, did not reduce the vehicle’s comfort. Four of the car with air conditioning, audio equipment, seat heating and air bags, etc., the trunk is completely available, an ordinary car drivers may not notice the modification and wiring. In addition, the process of moving the German test car a top speed of 130 kilometers, with an average speed of 90 km, much higher than the test car in Japan for 40 kilometers per hour. It is also worth mentioning that 605 kilometers is not the limit of the test vehicle mileage, because to Berlin after the end of it, and 18% of the remaining electricity. The researchers said the test vehicle could also consider using a different capacity battery pack.
according to the study of Germany, for the pure electric car, you need endurance 200 km from the city to fully meet the general needs of consumers, the best was 250 km. Thus, the German R & D planning is the original 2015 to a single charge of more than 300 kilometers of driving cars on the road. Now, in the German Federal Ministry of Economic Affairs, supported by DBM Energy Corporation and lekker Energie jointly conducted this trial marks the targets have been achieved ahead of schedule. Therefore, the success of the electric vehicle test by the German government and the industry of high praise. German Federal Minister of Economic Affairs and the Mayor of Berlin, respectively, press releases and organized the celebrations and delivered a warm speech, Audi, BMW, Mercedes, Opel and Volkswagen, also sent representatives to participate in the activities.
miracle from KOLIBRI technology
electric vehicle battery technology is the key. Cruise 600 km on one charge of driving ability to make electric vehicles and conventional fuel vehicles have been completely different, which will greatly promote the development of electric vehicles and to accelerate its market-oriented process. The researchers said the test car’s battery using the forward-looking technology – Alpha polymer technology hummingbird (KOLIBRI AlphaPolymer Technologie), the technology is high-quality individual components of complex intelligent systems.
KOLIBRI battery inside the flaky single component, the battery pole is graphite, the other pole is the lithium metal oxides, in the middle is the electrolyte. Different from other batteries, battery components of this very thin layer, the thickness is only about the diameter of a human hair. KOLIBRI battery performance is based on the complexity of the membrane technology, the battery has a high stability and high efficiency. The layered structure of the battery liquid electrolyte abandoned, reducing the high heat generated when current output, thereby increasing efficiency to 97%. And this can all run out of battery power contained and will not cause harm to the battery. As the internal battery does not contain heavy metals, toxic gases, liquids or acid, so it will not polluting the environment in particular. In addition, KOLIBRI very short battery charge. If you provide enough electricity to charge the battery used in the experiment takes only 20 minutes. Even more looking forward to is alleged that the battery life up to 50 million kilometers.
intuitive point of view, this intelligence based on lithium metal polymer battery energy storage devices, other than to be efficient and lightweight. Allegedly used in the test KOLIBRI battery capacity is 100 kwh, the total material of about 300 kg, were divided into two installed. It can provide 55 kilowatts of power, equivalent to 1.4-liter gasoline engines. The same weight of lithium-ion batteries, by nearly 200 lithium-ion battery modules battery module, the capacity of less than 30 kilowatt hours and mileage is only 150 km. And lead-acid batteries if compared, KOLIBRI more obvious advantages of the battery, using 100 kg KOLIBRI battery can easily beat the truck containing 1,200 kg of lead-acid batteries the truck.
security and a bright future prices or to interfere with
electric car test was successful, lekker energy company, said general manager Mike, technology research and development phase is over, the battery is still not mass production, it is also not listed.
experts said, the electric car is only the beginning of KOLIBRI technology, the future of the technology will be widely used in many other areas, such as wind and solar and other renewable energy storage, to address the problem of power fluctuation . Their goal is to achieve sustainable management of the environment, and create a clean pollution-free future.
DBM group was only established in 2005, but in the absence of external funding support may be developed under the influence of KOLIBR revolutionary battery technology, although this technology has received the German Innovation Award in 2010, and create a new world record for traveling long distance electric cars, but can quickly get the favor of the major car companies is still unknown. All along, the car companies are more concerned about their own, and now, while they are closely KOLIBRI technology, on the other hand, said lithium metal polymer battery serial applications barriers still exist, the lack of cost and safety of the battery and so vital information on everyday applications.
lithium battery for car companies to emphasize safety issues, the reporter interviewed the Department of Chemistry, Technical University of Berlin electrochemical energy, catalytic and materials science laboratory, Professor Peter Strasser. Professor Strasser said: “The lithium metal technology is not a new technology, but the predecessor of today’s lithium-ion battery. Lithium metal has advantages in energy density, but must pay attention to its security, large-scale lithium-ion battery is sufficient safe thus far, is still uncertain, so most car manufacturers do not want to use the lithium metal in the car. I think that the battery charge and discharge process in the security and prevent excessive heat and other key technologies also need to continue research.
