In the increasingly serious energy crisis, the state attaches great importance to today’s environmental protection energy conservation, new energy vehicles has gradually become the focus of the industry. July 2010, Shandong Qingdao Yi Green Star Electric Bus Expo as the designated car service, has been put into mass production and use of SDL6120EVG single layer of pure electric city bus and SDL6110EVSG type double electric city bus, caused the parties to participate Council’s attention.
As the pioneer of new energy vehicles, Yi-star passenger bus has been committed to the development of new energy. April 2010, the first electric car star Yi Ministry of Industry organized by the electric car production access to the review of qualifications, and has successfully trial SDL6120EVG type electric double-decker city bus and SDL6110EVSG type electric city bus, and volume in Linyi run. 2010 is “10 City 1000″ demonstration project to promote the second year, after 2009, market development and technical exploration of bus companies in new energy technologies and product line positioning have a more clear direction KD186 battery , GD761 battery , new energy bus sales have also been gains. In recent years, Yi-star bus with Beijing University of Science and Technology, Energy Research Institute, Linyi City in the new century a number of passenger cars such as cooperation in the field of new energy technology, new energy bus mastered the core technology design and manufacturing, has accumulated a wealth of new energy bus manufacturing experience.
Electric technology, so that a longer life mileage
Yi-star bus with China’s first patented technology to obtain lithium battery production Xinxiang Huanyu Group up to 10 years of cooperation, in the “lithium iron phosphate,” power battery applications, to develop battery technology of dynamic management and control, making Yi Star Bus Mileage greater than 300 kilometers (DC576V/360Ah), significantly improve the battery cycle life, is currently the longest battery life of pure electric passenger car mileage.
Yi satellite bus technology in the electric field results, attracting the world’s “Lithium” father of Japanese ENAX Ozawa and the Code company concerned, “863″ program of major energy-saving and new energy vehicles project supervision team leader Wang Binggang, said: If Mr. Ozawa to join the international cooperation Yi-star bus and coming to China will be a major boost power batteries Inspiron E1705 battery , Inspiron 9400 battery .
Why introduce the concept of electric cars a long time, but has not been popularization. The main reason lies in battery technology and charging service life can not be effectively addressed.
Fully digital servo control technology, so that occupants are more comfortable
Beautiful car, according to the new Chairman of the Group Jiabing Cheng said: At present, Yi Star Bus is working with the world’s most advanced motor manufacturers - Japan Nippon Steel; Japanese electric car motors - Manufacturer of high-tech Mitsui; “servo motor” of the pioneer - Yaskawa Electric to discuss cooperation. So that Yi Star Electric Vehicle Co., Ltd. has been maintained in line with international skills.
Drive motor is based on vehicle dynamic performance requirements designed, manufactured, fully digital servo control device is a time-Technology Co., Ltd. research, development and production 8N544 battery , XPS M1530 battery . All-digital servo control system can process vehicles in an arbitrary acceleration and deceleration control, to achieve smooth torque and speed control switch, also with high braking energy recovery and the unique zero-speed lock function in Singapore.
Vehicle control systems, to achieve international advanced level
Yi-star vehicle control technology is the electric vehicle Co., Ltd. and Beijing University of Science and Technology, and Time Technology Co., Ltd. and co-design, development completed. And through the electric vehicle control language (EVCL) the secondary development of the completion of a number of different conditions under the control strategy, creating a number of products have independent intellectual property rights, its performance has reached the international advanced level.
Lightweight vehicle, the international advanced level
Yi-all-star double-bearing design electric buses, with a strong bearing capacity. As the load light weight aluminum alloy body, the number of passengers more than the similar model containing more than 35 people,Inspiron 1720 battery preparation designs the number of passengers (including battery weight) of 80 or more, according to the statistics, because most diesel vehicles or driving the current market The bus body design have to iron steel, non-normal quality of the battery system ready 12-12.8 tons. For the production of pure electric vehicles is about 2.5 tons should also add the weight of battery systems, both the quality of service combined preparation of 14 - 17.5 tons. It is understood that the double-decker bus with aluminum production with high value creation.
Yi, Alexander Star Bus and Bus plant in Britain’s only Asian expert Tang technical cooperation, on the whole body bearing structure of light material and research, and obtained 16 patents related to technology. Compared with the traditional bus, 12 meters wide aluminum frame vehicle, the single light 3 tons, 5 tons of double light, Latitude D830 battery and with the full implementation of the Aircraft bearing manufacturing technology, to fill the gaps in the car lightweight.
“Yi-Star Detection Technology targets the bus has reached or exceeded the national 863 program under the technical requirements, the leading domestic and international class. This marks the Development of electric vehicles in China with foreign countries is almost the same starting line , local technology has reached the international advanced level. “Professor Yu Datai electric vehicle test center in accordance with national test data, evaluation of star power bus, said Yi.
