Recently, a number of fires caused by electric bicycles are shocking. Electric bicycles are many people's daily means of transportation, it brings a lot of convenience to our lives, but due to improper use or parking, electric bicycle fire accidents occur frequently. There is data that 80% of e-bike fires occur while charging, and more than half of them occur during night charging; Ninety percent of e-bike fatalities occur in hallways, aisles, and stairwells. Let's see how terrible the fires caused by e-bikes really are!
Why are electric bicycles frequent**?
Many e-bikes are charged at night and are not charged at the designated location, resulting in no one knowing when the accident occurs, delaying the best time to fight the fire; In order to facilitate charging, some car owners privately connect wires, which is very easy to cause circuit failure; Some charging time is too long, more than 12 hours, which is easy to cause disasters.
The combustion temperature of the electric bicycle is high, and when a spark is generated, the flame temperature is 130; In just 30 seconds, the flame temperature can rise to 310, and the room temperature can reach 120 at this time; After 2 minutes, the flame temperature reached 690, the plastic parts of the electric bicycle were ignited, and the room temperature reached 180 220; In 3 minutes and 30 seconds, the entire e-bike was wrapped in flames, and the temperature reached a terrifying 1200, and the temperature in the room also exceeded 660!
The combustion of electric bicycles will produce a large amount of toxic smoke, the smoke is toxic, and the spread speed is fast, **30 seconds, the toxic smoke can cover the entire room and corridor, which will cause people**.
Xuhui District Fire and Rescue Detachment suggestedReasonably control the charging time, according to the size of the battery capacity, generally 8-10 hours to fully charge.
Do not charge indoors, if indoor charging occurs**, a large amount of toxic smoke will be generated.
Do not fly to the wire for charging, the current and voltage instability may cause**.
Do not park in the corridor, it is strictly forbidden to block fire exits and safety exits, and it is strictly forbidden to take the elevator.
Do not modify and disassemble, such as installing batteries, motors and other power devices.
Frequent maintenance and check the safety performance of batteries, circuit plug points, chargers, etc.
