There are many reasons why electric vehicles catch fire while charging, mainly including the following:
First of all, the charger is not qualified, or the charging line, socket and other lines aging, resulting in unstable current;
Secondly, the electric vehicle battery itself has problems, such as insufficient electrolyte, battery overheating and so on;
In addition, the charging environment is not good, such as overheated charging piles, flammable materials around;
Finally, improper operation, such as overcharging, charging time is too long. To sum up, the fire during charging of electric vehicles may be caused by a variety of reasons. In order to avoid such accidents, it is necessary to ensure that chargers, charging cables and other equipment are qualified, maintain a good charging environment, and reasonably control the charging time and amount according to the actual situation of the battery.
There are several reasons why an electric vehicle may catch fire while charging.
First, the charger used to charge the electric vehicle may have a design or manufacturing defect, resulting in a short circuit or overload, causing a fire.
Secondly, electric vehicle batteries may have quality problems, such as overcharging or excessive discharge, resulting in internal short circuits or thermal runaway of the battery, causing a fire.
In addition, the material of the charging cable used during charging is unqualified, aging or damaged, which may also lead to excessive current and increased resistance, resulting in overheating and causing fire. Therefore, in order to avoid a fire when charging an electric vehicle, you should choose a regular brand of charger and battery, regularly check the safety performance of the charging equipment, and ensure that the charging line is intact.
