Hydrogen fuel cell vehicles will become the second front in its own brand
"Our research and development of hydrogen fuel cell prototype vehicle more advanced level of performance can be said that the international advanced level, but compared to the leader of the international level there is a large gap." Professor Wang Binggang that "this is a more objective evaluation. "king of the National Clean Vehicle Action Coordination Leading Group Expert Group, the 863" energy-saving and new energy vehicles, "Major Project Office appointed expert.
"Energy saving and new energy vehicles," a major high-tech project office is the Division of Science and Technology (863 Program Office of modern transport technology) under the jurisdiction of the project management agency.
Over one billion yuan by the state development funds to support the stimulation of domestic auto companies eager to join the hydrogen fuel cell vehicle research ranks.
In addition to SAIC, Chery, etc. in the "15" during the participation in R & D enterprise, the Foton has joined. SAIC also from the field of hydrogen fuel cell car into the passenger area.
Mainly short board - hydrogen fuel cell life
Research and development in hydrogen fuel cell car, the Roewe 750 as the basis of "Shanghai" brand fuel cell car is the fourth-generation Chinese-developed hydrogen fuel cell cars, China now represents the most advanced level. The hydrogen fuel cell power system by the Shanghai Fuel Cell Vehicle Powertrain Co., Ltd. developed.
And third-generation fuel cell vehicle "Beyond the Three" compared to "Shanghai" brand fuel cell cars, vehicle dynamic performance more robust and efficient. 0-100 km acceleration from 19 seconds to 15 seconds, one-time continuous hydrogen charging mileage extended from 230 km 300 km, maximum speed from 120 km to 150 km. In addition, its higher degree of integration, vehicle stability, reliability has also been further improved.
Also equipped with a fourth-generation power system of the Shanghai Volkswagen Passat, Chery Eastar have a top speed of 150 km, 0-100km acceleration time of less than 15 seconds, filling a hydrogen gas can travel 300 kilometers, these performance did not differ much with the international advanced level.
In addition, the Dongfeng Motor have also entered the field of hydrogen fuel cell vehicles. In August 2004, Dongfeng Motor in Wuhan Polytechnic University, the Elysee as a platform, developed a hydrogen fuel cell car - "Chutian One." It is equipped with a 25 kilowatts hydrogen fuel cells as power, top speed of 103 km, but the mileage is shorter.
Hydrogen fuel cell bus research and development, in early 2002, Tsinghua University as the lead unit, and Dongfeng Motor Corporation, Beijing Bus Plant's five units of the overall group, bear country "15" 863 fuel cell city bus developed by the project. Tsinghua University has set up a Beijing Qing Hua Tong Technology Development Co., Ltd. as the industrial carrier.
At present, the latest hydrogen fuel cell bus maximum speed of 90 km / h, a hydrogenation maximum mileage of 300 km, the engine power output of 100 kilowatts. Compared with international advanced level there is a large gap.
November 15, 2007, China's commercial fuel cell bus demonstration project started the second period, Shanghai will be bidding for three to six conditions of Shanghai city bus fuel cell buses, a two-year model run.
Experts suggest that China has independently developed a fuel cell bus, the Chinese government has invested a lot of money. Abroad, the high price of fuel cell buses in order to promote China's policies and regulations to establish standards, suggested that China's fuel cell bus demonstration runs can also be added to the ranks.
In the engine, vehicle control technology, the level of domestic and international advanced level despite the differences, but this is not the most important development of hydrogen fuel cells difficult. The key problem lies in hydrogen fuel cell and battery life issues.
Wang Binggang said that currently the stability of the hydrogen fuel cell is still life 2000 hours, well below the international seven or eight thousand hours. Battery life of less than 2 years, while Japan is the most advanced 3 to 5 years.
It is worth noting that multinational companies have been involved in a domestic fuel cell vehicles.
The second approach - collaboration with multinational
In 2004, SAIC and GM signed a strategic cooperation framework for clean energy automobile agreement, both sides reached an agreement: general "Hydrogen III" hydrogen fuel cell vehicles from the first quarter of 2005 in China, a two-year model run. General Motors in 2002 introduced the "Hydrogen-III", based on the Pan Asia Technical Automotive Center in GM's North American and German engineering staff under the guidance of a range of integration, and the Pan Asia Technical Automotive Center will be responsible for the car future operation and maintenance.
In 2001, SAIC and GM China's Shanghai joint venture between Pan Asia Technical Automotive Center, with regard to the Buick GL8 introduced a prototype fuel cell vehicle called the Phoenix.
2005 Fuel Cell Bus Commercialization in China demonstration project bidding, SAIC, General Motors has supported to participate in the project bid and offer was GM's most advanced fuel cell drive system. At present, Shanghai Volkswagen's Passat has been produced hydrogen fuel cell vehicles, and will participate in Beijing during the Olympic Games transport services.
Wang, former vice president of SAIC major general said, because the commitment of some 863 colleges and universities and not in time to seize the latest international technology trends, so SAIC's hydrogen fuel cell vehicle research and development is not entirely rely on 863, but also cooperation with multinational companies .
SAIC did not disclose the parties concerned in the development of aspects of what kind of cooperation. However, the reporter has learned that domestic enterprises in the electronic engine control, vehicle control technologies, both traditional energy sources, or new energy vehicles, in collaboration with multinational companies, such as co-developed with Bosch electronic engine control technology .
Reporters noted that SAIC and GM's agreement also includes "the development of China's hydrogen fuel cell vehicles to contribute to standards and rules," such provisions. So, do not rule out the use of SAIC GM hydrogen fuel cell vehicles in China to influence standards.
