It is reported that the party's electric bicycle was bought on October 2 this year, and it took only 5 days when the accident occurred, and the battery was a replaceable battery rented on a third-party platform. At present, the fire department and other departments have intervened, and the cause of the deflagration of the electric bicycle is still under investigation.

Electric bicycle fires are not uncommon
A high degree of vigilance is warranted
4 dead and 3 wounded! An electric vehicle charging fire accident occurred in Shenyang
On September 13, 2024, a fire broke out in a residential building in Dabei Street, Dadong District, Shenyang City, Liaoning Province, killing four and injuring three. According to preliminary understanding, the fire was caused by the electric bicycle catching fire during the charging process downstairs, igniting the insulation layer of the building.
Sudden in the early hours of the morning! An electric bicycle caught fire in Beijing, killing 4 and injuring 5
In the early morning of December 28, 2023, a fire broke out on the first floor of a villager's self-built house in Dongxindian Village, Cuigezhuang Township, Chaoyang District, Beijing, resulting in 4 deaths and 5 injuries. After a preliminary investigation, the cause of the fire was caused by a fire on an electric bicycle.

What are the causes of the fire?
Let's take a look↓
How terrible is an e-bike fire?
Once an electric bicycle catches fire, the danger is extremely high, which can be summarized as: "fast, hot, poisonous, and explosive".
"Fast": extremely fast burning;
"Heat": the temperature produced when burned is extremely high;
"Poison": a large amount of toxic gas is produced during combustion;
"Explosion": The battery will explode after burning and heating.
E-bikes are common causes of fire
Overcharging
Charging an e-bike for too long can cause the battery to heat up, bulge, or even explode.
In the experiment, firefighters parked a fully charged e-bike in the first-floor corridor and charged it with a non-original charger. After testing, within 3 minutes, the internal temperature of the battery box quickly rose to nearly 900 degrees Celsius, and the ground temperature near the fire point reached 160 degrees Celsius.
Aging lines
If the electric bicycle is used for too long, the connection line is easy to age and loosen, causing leakage, poor contact or short circuit, and once the wire fails, the high temperature generated is easy to ignite the vehicle.
Illegal modifications
Electric bicycle batteries usually include lead-acid batteries, lithium manganese oxide batteries, lithium ferrous phosphate batteries and other types, these batteries have different charging voltages, which are prone to mixing during the modification process, resulting in overcharging and fire.

What is considered a retrofit?
1. Modify or modify the motor to make the engine exceed the rated power set by the original car;
2. Alter or remove speed limiting devices and pedal riding equipment;
3. Dismantle the speed prompt sound device;
4. Install a battery, or replace a battery that does not meet the rated voltage set by the original car;
5. Install umbrella stands and canopies;
6. Spraying, installing, and using special vehicle or similar sign patterns, alarms, and sign lamps without authorization.
Prevent e-bike fires
Care should be taken to properly use the battery
What are the signs of a battery explosion?
The e-bike caught fire while driving
And how to deal with it?
Be wary of 5 signs of battery explosions
The battery heats up
The battery temperature exceeds 65°C and continues to rise, which is an important precursor to a battery explosion. Battery heating can be caused by external short circuits, overcharging, or physical damage, and should be dealt with promptly.
The battery is deformed
The obvious swelling and deformation of the battery shell or single cell indicates that the battery has shown a certain degree of instability, and there is a high probability of thermal runaway and combustion.
Electrolyte leakage
The battery electrolyte leaks to the outside through the gasket or connector, which indicates that the battery guard structure has been damaged, and the possibility of internal short circuit is high, which is a safety hazard.
Pungent odor
The battery emits a pungent odor, which may be a gas produced by the breakdown of the electrolyte, indicating that the battery reaction has gotten out of control and may be overheating and combusting.
Current and voltage anomalies
The battery monitoring system detects abnormal fluctuations in current, voltage, or internal resistance, which exceeds the normal operating range, which indicates that a certain fault has occurred inside the battery and the safety has decreased.
What should I do if my e-bike catches fire?
Stay calm and stop immediately
Stay calm, and when a fire first starts, park your e-bike in a safe place as much as possible, away from crowds and flammable materials.
Turn off the power and evacuate quickly
Turn off the power of the e-bike when it is safe to do so to prevent the fire from expanding and at the same time stay away from the e-bike that is on fire.
If the fire is found to be under control, the fire should be extinguished quickly with a dry chemical fire extinguisher or carbon dioxide fire extinguisher. It is strictly forbidden to extinguish the fire of electric bicycles with water-based fire extinguishers, which are prone to the risk of electric shock.
If the fire is out of control and enters the stage of intense burning, evacuate immediately.
Call the police as soon as possible and seek help
Immediately call the 119 police for help, inform them of the specific location and situation, and wait for the arrival of fire and rescue personnel in a safe place.
