Electric bikes catch fire frequently! How to break it?
Recently, fire accidents caused by electric bicycles Occur frequently
How terrible are e-bike fires?
It only takes 90 seconds to kill someone Once on fire
After 90 seconds, the temperature will reach 200℃
Toxic gas produced by burning an electric bicycle
Enough to suffocate hundreds of people to death!
According to statistics from the National Fire and Rescue Administration of China
A total of reports will be received nationwide in 2023
21,000 electric bicycle fires occurred
An increase of 17.4% compared to 2022
Many accidents are
Caused by improper charging of electric vehicles
What causes electric vehicle batteries to explode?
Power batteries usually suitable for electric vehicles can be divided into two categories: lithium batteries and lead-acid batteries. Lithium batteries have become the preferred power source for electric vehicles due to their high power density, light weight, and environmental friendliness.
According to statistics from the China Electronics Industry Standardization Technology Association (CESA), lithium batteries accounted for 97.1% of China’s newly installed electrochemical energy storage capacity in 2020, which has certain advantages in the market.
The two main factors causing lithium battery explosions are overcharge and short circuit.
1-overcharge
Mainly occurs during the charging process of lithium batteries. Due to the resistance of the battery, the battery will accumulate a lot of heat during the charging process. The protection device in lithium batteries can provide a certain degree of protection against overcharge by detecting voltage. However, when the overcharge time is too long and the voltage continues to be too high, dendritic short circuits are prone to occur inside the lithium-ion battery, causing the temperature and pressure of the lithium battery to continue to rise, resulting in explosion and fire.
2-short circuit
Mainly occurs during the use of lithium batteries. When the lithium battery is in use, its own temperature will continue to rise, and the battery will also maintain normal heat dissipation. If the battery temperature is too high due to external factors, it will easily cause damage to the battery separator and cause a short circuit, which will cause excessive internal heat accumulation, trigger a chain chemical reaction, and cause the battery to explode and burn.
In addition, mixing charging equipment for electric vehicles of different brands can also cause damage to the battery.
In addition to the above considerations, you also need to look for a trustworthy lithium battery factory.
