Need to go to a professional agency for identification
Difficult to supervise

“Few people report or complain about the private modification of electric vehicles, so it is difficult to supervise.†The staff said, in addition, whether the electric vehicle exceeds the standard requires identification by a professional organization, which makes the supervision more difficult. At present, Luoyang City Industrial and Commercial Bureau can only increase management in the quality and sales of electric vehicles.
