Why are electric cars and batteries forbidden to enter the room?

Over the years, there have been countless fires caused by electric cars entering the house. Whether it is pushing the indoor charging of electric vehicles or flying private charging lines, it is a dangerous behavior and will be eliminated. Why are electric cars and batteries forbidden to enter the room? Where is the safest place to put the electric car? The following small series brings an introduction.

Why are electric cars and batteries forbidden to enter the room?

At present, the construction of residential quarters is intensive, especially high-rise buildings. If there is a fire, it is very difficult to rescue them. For high-rise residential quarters, fires can only be prevented.

When electric cars go upstairs, there is a risk of fire from the beginning. Personal experience, my office colleague, the newly bought electric car stopped in the corridor, and the lead-acid battery exploded without charging. Smoke was pumped from the first floor to the ninth floor, but it was found in time and no casualties were caused. In the end, the colleague compensated the public for the maintenance cost of about 10,000 yuan. Imagine what would happen if it happened in the middle of the night and was not discovered in time?

Secondly, if the electric car goes upstairs, even if it doesn't cause a fire, it will block the escape route when the fire occurs, and even produce combustion-supporting effect when the fire spreads, expanding the fire hazard.

Then the electric car went upstairs through the elevator, and there were many accidents in which the electric car exploded in the elevator. As a closed space, the elevator is very difficult to escape once it explodes, which may lead to serious consequences.

If you choose to charge the battery indoors, the battery of the electric vehicle will get out of control once it burns, and the extremely fast burning speed will produce a lot of toxic smoke, which makes it difficult for people to escape and the consequences are unimaginable. When the materials of electric vehicles burn, they will produce highly toxic gases such as carbon monoxide, which will diffuse in buildings. After high temperature smoke enters the trachea, it will cause serious burns and suffocation; The black smoke produced by the burning of electric vehicles easily leads to insufficient light in the building, which brings great difficulties to the evacuation of people.

Where is the safest place to put the electric car?

Electric bicycles should be safely charged in the outdoor centralized charging shed. The charging time of electric bicycles is generally less than 5 hours. When charging at night, the power supply should be cut off in time to avoid the fire caused by battery heating caused by overcharge. Pay attention to the following points when charging electric bicycles:

1. Electric vehicles should be parked and charged in an independent area (such as carport and garage) outside the building, and the area should keep a safe distance from the adjacent buildings.

2. Due to site environmental restrictions, centralized parking of electric vehicles, and the charging area cannot be independently set outside the building and must be attached to the building, it should be set on the first floor or underground floor of the building (if it can only be set on the first floor or underground floor, it must meet the relevant fire safety requirements).

3. It is forbidden to park and charge electric vehicles in the evacuation passage, exit, stairwell (entrance), floor corridor and elevator front room of residential buildings. 4. Parking and charging are strictly prohibited in group renting houses and crowded places.

5. Electric cars or their batteries shall not be charged in residential rooms and balconies, but only in open-air places such as courtyards.

6. The centralized charging area of electric vehicles shall be equipped with special charging devices and special distribution boxes. The charging device should have the functions of timing power failure, overload protection, short circuit protection and leakage protection.
