What problems may cause electric bicycles to catch fire?

Article Source：Pengpai News, Pengpai Account, Government Affairs | Author：Emergency Management Department | Issuing Time：2024.03.26
Although electric bicycles have brought great convenience to people's lives, once caught on fire, it may cause serious injury or property damage.

What problems may cause electric bicycles to catch fire?


1. Overcharging

Charging an electric bicycle for too long can cause the battery to heat up, swell, or even explode. Let's take a look at the firefighter's experiment together ↓

In the experiment, firefighters parked two fully charged electric bicycles on the first floor corridor and charged one of them with a non original battery charger. After testing, within 3 minutes, the temperature inside the battery box quickly rose to nearly 900 degrees Celsius, and the ground temperature near the ignition point reached 160 degrees Celsius.

2. Line aging

If an electric bicycle is used for too long, the connecting wires inside the vehicle are prone to aging, loosening, causing leakage, poor contact, or short circuit. If the vehicle's wires fail, the high temperature generated can easily ignite the vehicle's saddle and decorative plastic parts.

3. Improper use of charger

Many households have more than one electric bicycle, and mixing charging devices from different brands of electric bicycles can also cause damage to the battery. Chargers are consumables with a short lifespan and need to be replaced in a timely manner. When replacing, it is important to match the battery model.

4. Illegal modification

Electric bicycle batteries generally include various types such as lead-acid batteries, lithium manganese batteries, ternary batteries, and lithium ferrous phosphate batteries. The charging voltage of each type of battery is not exactly the same, and it is easy to mix and use during modification, which can lead to overcharging and cause fire and explosion.

What should I do if an electric bicycle catches fire?

1.If an electric vehicle catches fire, if conditions permit, the power switch should be cut off as soon as possible to prevent electric shock and leakage accidents;

2. Use ABC dry powder fire extinguisher or carbon dioxide fire extinguisher to extinguish the fire. In the absence of a fire extinguisher nearby, dry sand can also be sprinkled on the ignition point to extinguish the fire;

3. If the fire is urgent and difficult to control, quickly dial 119 to seek rescue.

To prevent electric bicycles from causing fires, please remember the seven "prohibitions"

1. It is strictly prohibited to purchase unqualified electric vehicles and accessories. Unqualified, non-standard, or excessive electric vehicles, batteries, wires, and chargers can increase the risk of fire.

2. Unauthorized modification is strictly prohibited. Unauthorized modification of batteries, installation of speakers, lighting, etc. can easily cause overloading of the circuit and lead to fires.

3. It is strictly prohibited to park without following the regulations. It is strictly prohibited to park electric bicycles in housing, underground garages, basements, and semi basements without implementing fire separation, supervision, and other preventive measures.

4. Charging in non designated areas is strictly prohibited. Charging is strictly prohibited in public areas such as crowded areas and residential buildings, such as public lobbies, evacuation routes, stairwells, elevated floors, and safety exits. Batteries cannot be brought home for charging.

5. "Flying wire charging" is strictly prohibited. It is strictly prohibited to charge electric bicycles using methods that do not comply with fire safety technical standards and management regulations, such as pulling wires privately or installing sockets randomly.

6. Charging near flammable materials is strictly prohibited. Electric vehicle charging should be kept away from electric bicycle parking areas and flammable and explosive materials.

7. Long term charging is strictly prohibited. Vehicles should avoid charging for too long, charging all night and being left unattended. If there is a problem with the battery, wires, etc., it is very likely to cause a fire.

Please check these safety measures when using an electric bicycle!

Most electric bicycle bodies are made of flammable and combustible materials, and once caught on fire, it can cause terrible consequences. To prevent electric bicycles from catching fire and exploding, start with me. The following preventive knowledge must be kept in mind!

1. Reasonably control the charging time

The charging time for electric bicycles should not be too long. According to the size of the battery capacity, charging can generally be completed within 8 to 10 hours.

2. Do not charge in residential areas

There are many flammable materials indoors, and once a fire breaks out, it can easily lead to a fire.

3. Do not charge with flying wires

Charging with cables at will can easily lead to fires due to factors such as line wear, aging, and extreme weather.

4. It is strictly prohibited for batteries to enter buildings and households

Do not park electric bicycles in the hallway. If an electric bicycle catches fire in the hallway, it will directly block the fire and escape routes.

5. Keep away from flammable and explosive materials when charging

When charging an electric bicycle, it is important to stay away from flammable and explosive materials to prevent the electric bicycle from catching fire and causing larger accidents.

6. Do not modify or repair without authorization

Modifying and repairing electric bicycles, such as adding speakers and modifying lighting, can easily cause overloading of the circuit and lead to fires.

7. Do not use non-standard products

Be sure to purchase legitimate and qualified electric bicycles and accessories, otherwise it will increase the risk of fire.

8. Prohibit internal water ingress

Once water enters the interior of an electric bicycle, it may cause a short circuit, leading to accidents such as vehicle self ignition.

In summary, by following and practicing the above suggestions, we can significantly improve the charging safety of electric bicycles. This is not only a protection for our own safety, but also a responsibility for the safety of others and the public. Only by correctly recognizing the importance of charging safety and integrating it into daily charging behavior can we jointly build a safer, greener, and more efficient travel environment.
