In order to meet the challenges brought from heavy air pollution and shortage of traditional energy sources, great efforts and huge financial investment have been spent on R & D for new energy-use vehicles in recently years, such as electric vehicles and vehicles that use alternative fuels. Great progress has been made in the areas of accumulated technologies, model samples and partial industrialization, etc. However, there still exist many problems in the mass production of these new energy-use vehicles.
