The new energy subway electric rail car adopts the direct-alternating transmission system.The lithium battery pack with high energy density is used as the power source to drive the permanent magnet synchronous traction motor to drive the vehicle.The vehicle is mainly used for transport traction and shunting in subway tunnel following mechanized construction.At the same time it is also suitable for coal,metallurgy,mining,railway,highway tunnel construction and other industries railway ground transport traction.

　　The car has the advantages of low noise,zero emission,strong power,user-friendly operation design,active and passive safety protection,good charging portability and so on.It is a major trend of the future development of rail cars,and is of great significance to the green construction method.
