Abstract


With the development of society , energy and environmental aspects of the crisis has become increasingly evident . Car as the most important means of transport in today's society , and its position is irreplaceable . With the increase in car ownership , vehicle exhaust emissions has also become more concerned about the problem of Governments . In order to deal with the problem of high energy consumption and high emissions of the car , the whole world in the development of new energy vehicles to reduce vehicle exhaust emissions , such as hybrid vehicles , pure electric vehicles , hydrogen cars and solar cars . City buses as public transport , its exhaust emissions in the overall emissions occupy a large proportion of the development of pure electric city bus to reduce the urban automobile exhaust emissions , ease the contradiction between the urban economic and environmental significance . This article is a trial JAC chassis, (HFC6601KYD3) , the basis of the power of pure electric city bus system . Needed for the operation of urban public transport , to develop a pure electric city bus power target : the maximum speed of 50km / h Gradeability 8% , acceleration time of 35s , the driving range of more than 80km , and then based on the dynamic target parameters match the drive motor ; in the structural form of the power system , this project is to replace the engine motor retains the original car 's clutch , gearbox and other mechanical transmission system ; matching and layout design of pure electric city bus battery pack ; ADVISOR 2002 pure electric city bus for modeling and simulation . Based on the national pure electric vehicle power test procedures (GB / T 18385-2005), combined with the operating conditions of the city bus , and to develop pilot programs . The test includes 30 minutes maximum speed test , maximum speed test , to accelerate performance test and continued driving mileage test . Test results : the maximum speed of 51.3km / h test Gradeability 12% , acceleration time of 30.5s speed of (50 ± 5) km / h under the test conditions , continued driving mileage of 81.6km . The test results meet the power requirements of the pure electric city bus .
