Cause
The possible causes of an electric vehicle catching fire while charging are as follows:
1, line aging: electric vehicles have been used for a long time, and the connection route in the car is easy to age and short circuit. If the wires in the car are short-circuited and the external temperature is too high, some things such as plastic materials are easy to burn.
2, battery short circuit: lead-acid battery battery life is long, internal circuit short circuit will cause spontaneous combustion.
3, the charger does not match: many families now have more than one electric car, the mixed use of different brands of electric car chargers will bring damage to the electric car battery, and there will be safety risks.
4, overcharging: In general, electric vehicles can be charged for about 8 hours to meet the needs of users. However, many users charge before going to bed in order to save trouble, charging for 12 hours or even longer, which will reduce the life of the battery and easily cause safety accidents.
5, voltage instability: multiple electric vehicles charging at the same time, private wire charging, will lead to voltage instability, easy to cause safety accidents.
6, charging environment: Many users often push electric vehicles into the stairwell, walkway or push electric vehicles into the room to charge. Once a fire occurs in an electric vehicle, the smoke will block the safety exit and escape channel, which is easy to cause casualties.
Summary: When charging electric vehicles, safety should always be kept in mind to avoid the above situation.

Extended data
Electric vehicle charging safety knowledge:
1. When charging, a good ventilation environment should be selected, and indoor charging is strictly prohibited.
2, the charger is carried with the car to take protective measures to avoid long-term turbulence damage to the internal components, resulting in security risks during charging.
3. When charging, the charger should be placed on the foot pedal, and it is strictly prohibited to cover or place it on the seat cushion or in the seat bucket.
4, the charging time is 8 to 10 hours is appropriate, do not charge the electric vehicle for a long time.
5, when charging, do not extend the power cord at will, pull to pull, to avoid loose joints, line aging, wire rubber damage short circuit fire.
6. When charging, the electric door lock must be closed. If the charging battery voltage of the electric door lock is raised, the electric door lock will be burned out, causing a short circuit fire.
7, charging should choose a qualified flame retardant wire, and the line has leakage protection device.
It may be that the voltage is unstable, it may be that the charging equipment that the wire is aging, and it may be that his battery car is too old, riding for too long, easy to fail, resulting in easy to start, so the battery car must pay attention to safety when charging, do not put it in the corridor to charge, it is easy to happen dangerous
