Electric cargo bikes, which are often used as transportation tools, have become an indispensable part of people’s daily life. However, there are hidden risks in the batteries of electric vehicles. There are many safety accidents caused by fires caused by electric vehicle batteries. At the same time, battery combustion can also generate a large amount of toxic and harmful gases, threatening human health.
In order to better popularize relevant knowledge for electric vehicle users, the fire department conducted an experimental simulation of the fire situation of electric vehicles, and issued a set of shocking numbers.
The experimental data results show that when an electric vehicle catches fire for 3 minutes and 30 seconds, the entire vehicle body temperature can reach 1200 degrees Celsius, accompanied by a large amount of toxic smoke, which is extremely prone to causing casualties.
In relevant data surveys, there are various reasons for electric vehicle fires, among which the following are the most common causes of fires.
1. Some electric vehicle batteries are old and have not been updated in a timely manner, which can easily cause a fire;
2. Some stores will privately modify the electrical wiring in the motor vehicle and replace larger capacity batteries, resulting in overload or short circuit of the wires, causing a fire;
3. Due to nonstandard charging causing fires, some electric vehicle owners may choose to pull electric wires privately or push the electric vehicle indoors for charging for convenience. This operation not only easily leads to fires, but also can block emergency exits, causing disasters.
4. If the selected charger does not match the original battery, it is easy to cause failures.
If electric vehicles are equipped with fences, cushions, and other equipment, they are extremely flammable materials. These configurations can accelerate combustion and generate toxic gases, causing disasters.
To avoid danger and safely charge your electric vehicle, we will give you the following suggestions:
1. Never overcharge an electric vehicle. Generally, after 8-10 hours, it is necessary to stop charging, unplug the charger, and promptly replace the battery if it is found to be aging;
2. Do not modify the wiring of electric vehicles without permission, and do not choose inferior chargers;
Please do not remove the speed limiting device of the electric vehicle, and do not charge the electric vehicle immediately after use.
3. Electric vehicles should not be charged by flying wires, nor should they be charged in indoor environments such as stairwells and hallways.
