What does it mean that battery cars are forbidden to enter the elevator?

Excuse me, are you asking the question "What do you mean, battery cars are forbidden to enter the elevator"? This sentence means to ensure the safety of the public and the normal operation of the elevator.

1, elevator operation safety: the battery car entering the elevator will increase the bearing burden of the elevator, lead to the damage or failure of the elevator, block the escape route, affect evacuation, and cause the risk of secondary injury.

2. Prevention of fire hazards: There are safety hazards such as electric leakage and explosion in the batteries of battery cars. After the battery car enters the elevator, it is charged in the elevator or there is a fire. Due to the limited space in the elevator, the fire spread rapidly, causing harm to passengers and people in the elevator.
