1. When charging electric bicycles, there are four major safety hazards:
1.Aging lines.
2.Overcharging.
3.The charger does not match.
4.The voltage is unstable.
IIWhy do electric bikes be**?
The electric vehicle fires all occurred during the charging process, because the electric vehicle was too full, and the plug was not pulled out in time to cause a disaster, and ignited the electric vehicle parked next to it.
The electric car fire occurred between 8 p.m. and 5 p.m. the next day90% of the fire caused by electric vehicles is because electric vehicles are parked in the hallway, aisle and other parts.
3. The old battery is one of the sources of fire, and the old battery swells after long-term charging. For long-term charging, the temperature inside the battery may be as high as 100 degrees Celsius, which will cause the electrolyte to evaporate due to the high temperature, and the copper wire will be scalded to the bare surface. Once the exposed positive and negative electrodes are in contact, a short circuit occurs, and it will be ** instantly.
4. In life, most of the accidents of spontaneous combustion of electric vehicles are caused by the lack of short-circuit protection devices, resulting in short-circuit fires. Especially charging in the house, it is equivalent to putting a time bomb in the house.
5. There is no charging socket, and the wires are privately pulled and the flying wires are charged, resulting in leakage. Especially on rainy days, it is most likely to short circuit.
6. Modify electric bicycles without permission, transform tram lines, and use high-power batteries.
3. Preventive measures
1.It is forbidden to park and charge electric bicycles in corridors, safety exits and other areas.
2.Inspect your e-bike regularly and replace batteries that are more than 2 years old.
3.Do not change privately, dismantle the electric bicycle privately, especially do not improve the battery at will.
4.Strictly abide by the safety use specifications of electric vehicles.
