Recently, it has happened in many places in China.
Fire accidents related to e-bikes.
It's heart-wrenching. 
At about 10:13 on February 25, a fire broke out in an electric carport on the north side of Building B, Rising Sun Jiayuan Community, Majiapu Street, Fengtai, Beijing, and the cause of the fire was preliminarily determined to be caused by a battery failure.
On February 23, 2024, a fire broke out in a residential building in Mingshang Xiyuan, Yuhuatai District, Nanjing, Jiangsu. After preliminary analysis, the fire was caused by the parking of electric bicycles on the overhead floor of the ground of 6 buildings.
Electric bicycles have made people's lives easier.
However, once **.
It may cause great damage to people's lives and property.
E-bikes**.
What could be the trigger?
Overcharging
Charging an e-bike for too long will leave the batteryFever, swelling and even**。Let's take a look at the firefighter's experiment In the experiment, the firefighter parked two fully charged e-bikes in the first-floor corridor and charged one of them with a non-original charger. Tested,Within 3 minutes, the temperature inside the battery compartment quickly rose to nearly 900 degrees CelsiusThe ground temperature near the ** point reached 160 degrees Celsius. Aging lines
The electric bicycle has been used for too long, and the connection line in the carIt is easy to age, loosen and lead to leakage, poor contact or short circuitIf the vehicle's electrical wiring fails, the high temperature generated can easily ignite the vehicle's saddle and decorative plastic parts.
Improper use of the charger
Many families have more than one electric bike, different brands of electric bikesMixing charging equipment can also cause damage to the batteryThe charger is a consumable product, with a short lifespan, and needs to be replaced in time. Link to the case
On October 5, 2021, on the first floor of a residential building in Fumian District, Yulin, Guangxi, 10 electric vehicles and 1 motorcycle were burned, and 1 woman and 1 child died. After investigation, the reason was that Wu Mouhai, a tenant of a residential building, purchased a lithium battery for an electric vehicle that did not meet the safety standards on the Internet and installed it on the electric vehicle himself. Wu MouhaiWhen charging an electric vehicle with an unsuitable charger, the lithium battery bursts with thermal runaway, causing a fire. Illegal modifications
There are generally many types of electric bicycle batteries, such as lead-acid batteries, lithium manganese oxide batteries, ternary batteries, lithium ferrous phosphate batteries, etc., and the charging voltage of various batteries is not exactly the sameIn the process of modification, it is easy to mix, which leads to overcharging, which in turn leads to ***
Link to the case
On December 13, 2023, a fire broke out in a high-rise community in Huidong County, Huizhou, Guangdong, and the ** point was located in Room 8 on the 12th floor, and two minors were killed in the accident. After investigation, the cause of the fire was that during the charging process of the electric bicycle pushed indoors, the battery heating was out of control and ignited the surrounding combustibles. It is reported that before the accident, three electric bicycles were placed in the living room of the accident site, and there was also an electric car in the room; Upon investigation, the living roomThe 3 e-bikes are all modified, and the chargers of the e-bikes are not original matching
What should I do if I encounter an e-bike**?
In case of electric cars**, conditions permittingThe electric switch should be cut off as soon as possiblePrevent electric shock and leakage accidents
Use an ABC dry chemical fire extinguisher or a carbon dioxide fire extinguisher to extinguish the fire, and in the absence of a fire extinguisher nearby, it is also possible to use:Extinguish the fire by splattering dry sand at the ** point
If the fire is urgent and difficult to control, call quicklyCall the police** for rescue.
Prevent e-bike fires
Keep in mind the seven "don'ts".
1.It is strictly forbidden to purchase unqualified electric vehicles and accessories. Unqualified, non-standard or over-standard electric vehicles, batteries, wires, and chargers will increase the risk of fire.
2.Unauthorized modification is strictly prohibited. Unauthorized modification of batteries, installation of audio, lighting, etc., is easy to cause overload of the line and cause fire.
3.It is strictly forbidden to park outside the regulations. It is strictly forbidden to park electric bicycles in housing, underground garages, basements, and semi-basements that have not implemented preventive measures such as fire separation and guardianship.
4.It is strictly forbidden to charge in non-designated areas. It is strictly forbidden to charge in public areas such as public foyers, evacuation passages, stairwells, overhead floors, and safety exits in crowded places and residential buildings, and batteries cannot be taken home for charging.
5.It is strictly forbidden to "fly wire charging". It is strictly forbidden to charge electric bicycles in a way that does not meet the technical standards and management regulations of fire protection such as pulling wires and installing sockets indiscriminately.
6.It is strictly forbidden to charge near flammable materials. Electric vehicle charging should be kept away from electric bicycle parking places and flammable and explosive materials made of flammable and combustible materials.
7.It is strictly forbidden to charge for a long time. The vehicle should avoid charging for too long, charging overnight and leaving it unattended, once there is a problem with the battery, wires, etc., it is very easy to cause a fire.
Use an e-bike.
