Beijing Olympic Games, the first time in the international large-scale lithium battery electric vehicle applications

Moment is the corridor along the cliff, while a desert style, while that south of Yangtze River, while Whitewater is Montenegro, if not the Bird’s Nest, Water Cube, the landmark building, you may need to ask ourselves into the ink in the world. Yes, this is the summer of 2008 Beijing Olympic Village – a unique style urban high-rise side of the small world. 50 electric shuttle bus slowly in the Olympic central area in a lush green belt among the athletes, coaches and media to provide convenient transport services. Corner of the Olympic Village, an area of 5000 square meters of electric vehicle charging stations for electric bus to provide power supply to achieve zero emissions throughout the T4 area.

All the circumstances foreseen in the near few months later in the show in the world. Similarly, Beijing Jiaotong University, “as the Olympic services, transport services for the Olympic Games” also is not just a slogan, this 50 electric buses in the battery management system is developed by the University School of Electrical, technical support unit for the charging station is also the subject group responsible. At present, the charging station construction has entered the sprint stages.

Battery management system reliability

According to project leader Jiang Jiuchun vice president of the introduction, in 2008 Beijing Olympic Games is the first time such a large scale application of international lithium battery electric vehicle, the project has great challenges. Currently the cost of each electric bus is about 1.4 million, of which the cost of the battery reached 4, 500 000. As an important part of the battery system, battery management system (Battery Management System, BMS) to bear the real-time monitoring battery status, optimization of use of battery power and protect the important responsibility of battery safety. Beijing Jiaotong University, Electrical Engineering from the “Ninth Five-Year” period began for the pure electric and hybrid electric vehicle development and design of BMS. Cover the lead-acid battery type, nickel metal hydride and lithium ion batteries. System with its stable performance, strong anti-interference, interface available, easy to install and high reliability has won wide acclaim users, developed battery management system successfully passed the national authority of the electromagnetic compatibility test and successfully installed in the electric car completion of the high-temperature, low temperature and high altitude such as performance tests. 121 Road through the Beijing Electric Bus Demonstration Line and effective long-term service and technical support by Beijing Municipal Science and Technology Commission and the government alike.

In order to better battery management systems team testing and in-depth study, now in Beijing Jiaotong University, Electrical College has completed a battery charging station can achieve all of the features (including the battery and battery management system 10 Xiang, charging Jizu and monitoring network) small-scale simulation of battery charging stations, charging stations simulate the operation of the Olympic process, charging stations for the smooth construction of the Olympic Games to provide technical support and solutions. R & D team acquired a Digatron (maximum output voltage of 500V, maximum output current of 300A) Battery testing equipment for battery on group performance in-depth testing and analysis, to further enhance the battery management system provides functionality and performance effective protection.

Accumulation of the team’s strength

Beijing Jiaotong University in 1997 and began to get involved as early as the battery charging area, the first electric car in the country began to test run the experiment and demonstration area, with many years of research, in 2002, the school successfully become one of major projects, the Olympic Games, “electric vehicles to run demonstration, research and development and industrialization, “the project to participate in unit commitment management system and electric vehicle battery charging technology research. The project is the Ministry of Science, Beijing Municipal Science and Technology Commission in the “Ninth Five-Year”, “15″ “electric car key” based on the common organization and implementation, and aims for the Beijing Olympics, the use of green environment-friendly vehicle to provide technical support to promote our industrialization of electric vehicles.

Professor Jiang Jiuchun said that after 10 years of technology accumulation, in terms of school size and the team management has been a qualitative change, relative to the base ten years ago, Shantou, technical input into the continuously intensified. School designed electric bus battery management system in Beijing, 121 Road Electric Bus Demonstration Line, Beijing Miyun demonstration zone, Dongfeng 2 gas, Chongqing Changan, etc. are widely used, works well. In 2007, the team made in battery applications initial results, the Ministry of Education involved in the project received a first prize of scientific and technological progress, the existing battery management system has been able to meet the pure electric and hybrid vehicles, including the large-scale application.

Olympic charging station technology research since 2003, built 2004, a 20-car charging stations used to run the demonstration, had already become the largest electric vehicle charging station; 2005, 14 lead-acid battery tram, “a district line “(121 Model Line Road and Miyun Electric Bus Demonstration Area) for model run; 05 start, lithium-ion batteries begin loading test, to achieve a dozen of the world’s first lithium battery electric vehicles to run. 2006 Olympic electric vehicles like cars (2) performance tests started, get notice and license, in 2007 the second round of the actual capacity of 5 vehicles to run, the successful completion of testing in summer heat and winter low temperature. System is reliable, anti-interference ability, to meet the needs of the actual operation of electric vehicles.

“Others can be put aside, this matter must be pegged. Pressure to be bigger, should do everything possible to ensure that no any problem.” Is such a word, the research group of students from dawn to dusk, heart meditation is the Olympics The early success.

In the central area of the Olympic Games, Olympic officials, coaches, athletes will not hear the roar of car engines, smell the exhaust, electric buses will be the Beijing Olympics a green carrier, technology carrier. Jiang Jiuchun prospects for the development of management systems with confidence. 50 The use of pure electric passenger car fuel economy of about 1800 liters per day, about 4,230 kg CO2 emissions; pure electric and fuel cell vehicles in motion can achieve zero emissions in energy-efficient hybrid vehicles also can greatly improve the emissions ; In addition, the pure electric vehicles and fuel cell vehicle noise is far lower than conventional internal combustion engine vehicles. In the future, the concept of green traffic will continue to develop.
