Is there a provision prohibiting electric vehicles from entering the elevator?

hello, yes! Article 37 of the Regulations on Fire Safety Management of High-rise Civil Buildings, ordered by the Emergency Management Department, clearly stipulates: "It is forbidden to park or charge electric bicycles in public halls, evacuation walkways, stairwells and safety exits of high-rise civil buildings." Article 47: "In violation of these regulations, anyone who commits any of the following acts shall be ordered by the fire rescue agency to make corrections, with a fine of more than 2, yuan and less than 1, yuan imposed on business units and individuals, and a fine of more than 5 yuan and less than 1 yuan imposed on non-business units and individuals: (7) parking electric bicycles or charging electric bicycles in public halls, evacuation walkways, stairwells and safety exits of high-rise civil buildings, and refusing to make corrections."
