50 electric buses rolled into the Olympic Village will be the world's leading technology

Fuchengmen sit every day in 121 members of the public laptop battery, acer battery road has long been familiar with the operation of this route is the famous domestic first plies of pure electric bus fleet. "Parking a smooth start, the noise is small, comfortable ride." Passengers commented on the zero-emission electric buses.

Today, this team has been added to a pure electric car 4, although the appearance of more than 10 vehicles with the previous electric cars are not very different, the provision of kinetic energy from the traditional lead-acid batteries into the battery of advanced lithium batteries, a significant level of technology upgrade. The most notable is that they will follow-up to 5 lithium tram shared in the Olympic Village for next year's operating 50 electric buses to do the task of testing operations.

By the end of simulation is expected to run in the Olympic Village

Beijing Olympic Games electric bus is included in the national "863 Plan" and Beijing "Hi-tech Olympics" planning an important part aspire 3000 battery, aspire 3500 battery . One of the main person in charge of the project, Beijing Institute of Technology Center of Electric Vehicle Factory director Lin Cheng told reporters: "In the 121 road test operations on the basis of 50 electric buses in the coming months will complete the production end of this year or next year regional input to the simulation of the early running in the Olympic Village. "

12 meters long, eighty or ninety people's pure electric passenger bus running day and night in the Olympic Village, Athletes Village series, information centers and major competition venues, which in previous Olympic Games so far have not have had. Coupled with a variety of operating within the Olympic village and convenient battery car, electric vehicle fleet will reach the Beijing Olympics as much as hundreds of cars.

1 km consumption not more than 1 degree

Compared with ordinary bus, there is no pure electric bus exhaust emissions, and environmental protection advantages of self-evident aspire 5000 battery, aspire one battery. However, the lead-acid battery car or face a charge driving range of only 100 km, used batteries refractory likely to cause environmental pollution problems. In this regard, Lin Cheng said: "Next year in the Olympic Village operation of 50 electric buses will be fully train a lithium battery can be replaced as quickly as mobile phones, centralized charging, in order to meet the needs of a 24-hour operation."

According to reports, when compared with lead-acid battery car, lithium higher cost of electricity transport about 40 million, but the same charge 45 hours, the same weight of 1.5 tons of batteries, driving range can be increased to 200 km. More importantly, the service life of lithium is much longer and more technical level of domestic already recharged 500 times or 1000 times or more, which means that the total mileage electric buses could reach 100000-200000 km.

But even more proud that, through expert review, the Beijing performance of pure electric bus technology, especially energy saving has been among the world's advanced level. Jinghua Coach Factory, Wang Yan, deputy director of Technology btp 60a1 battery, inspiron e1705 battery Center for Health praised: "Even in the actual operations, the 121 road electric bus power consumption per km is also a degree within the testing ground for low power consumption per kilometer to 0.7 to 0.8 degrees, which is already the level of the world's leading. "It is understood that the western countries, research and development of pure electric bus power consumption per km is about 1.3 to 1.4 degrees.

Than the existing carbon materials (372 mAh / g) higher capacity anode material for studying the hot Dell TD347 , Dell U4873, the tin oxide was first found to have excellent lithium storage performance, leading people began to study a series of metals and oxides based on The anode material, however, tin, silicon, etc., as anode materials for lithium-ion batteries a fatal question: charge-discharge process, with the embedded lithium repeated extrusion, volume change of up to 300% -400%, resulting in the mechanical stability of the lower electrode, powder materials are also due to the gradual failure occurs, the cycle of poor performance.

Huang Xue-Jie said, nano-alloyed tin-based materials can overcome this weakness has been obtained in the SONY's Nexlion application, the physical location in 1998 issued a paper pointed out that the nano-technology is to improve the cycle performance of such materials, an effective way panasonic cgr-s602e , panasonic dmw-bm7. Domestic Chinese steel Research Science and Technology Corporation in the support of 863 has been initially developed with a certain cycle stability of the tin-based materials. Around the world, with a high specific capacity of the non-carbon negative electrode material is in a large-scale commercial application of the initial stage, using three-dimensional sets of fluid materials, lithium-ion battery anode materials to improve the electrochemical performance and is the current international field of lithium-ion battery A major research focus.

Anti-injunction request was rejected Qualcomm's chips are still banned mobile phones

June 25 news, the U.S. International Trade Commission (ITC) has rejected a request by Qualcomm, the contents of the request to require the elimination of the ITC banned the import of Qualcomm chips built-in mobile phones commands with hp f4809a battery . ITC believes that these products used in mobile phone chips infringed Broadcom's patents.

According to Reuters, earlier this month, ITC announced its ban on the import of Qualcomm chips with built-in high-speed wireless mobile phones new products, import decisions. The ban on June 7 had been imported before the exemption of those mobile phones. Broadcom Corporation have repeatedly expressed the hope that with the high pass on the patent issues to discuss and look forward to reach a certain agreement. Qualcomm was not immediately respond to this, but recently, the company said its executives could not accept the terms proposed by Broadcom of pavilion zd8000 battery.

Qualcomm has asked a U.S. federal appeals court for emergency suspension of ITC's ban. The Federal Court of Appeal will hold a hearing and will be given ITC on June 27 before the debate the opportunity to explain why it could not abolish the ban. Qualcomm has said it will request President Bush to veto the ITC ban. The ban was issued by President Bush have the right within 60 days after the ban of this review.

U.S. institutional investors, said Oppenheimer analyst LawrenceHarris, Qualcomm's request was rejected it was not surprising, but also the president hp rechargeable battery of the ITC's intervention is also very rare.

The ban is executed, the victim will include communication service providers VerizonWireless, SprintNextel companies as well as South Korea's Samsung Electronics Co. Ltd. and LG Electronics.
