Electric vehicles may catch fire spontaneously due to battery issues. Hot summer weather can cause batteries to overheat, leading to spontaneous combustion. Alternatively, it could be due to battery quality problems or improper charging practices during the charging process. The specific reasons are as follows: 1. Battery issues: In the scorching summer, electric vehicles perform well while driving as the cooling system is operational. However, after parking, the cooling system stops working. The high internal battery temperature from driving combined with the external high-temperature environment can cause the battery to overheat, potentially leading to spontaneous combustion. Additionally, although electric vehicles can drive in rainy conditions without issues, water must never seep into the battery. If water enters, it can cause a short circuit, leading to spontaneous combustion. 2. Quality issues: Currently, most new energy electric vehicle power battery packs are not produced by the automakers themselves but rely on battery manufacturers. Therefore, minor defects in the manufacturing process of some new energy electric vehicle power batteries may go unnoticed. These undetected power batteries may be directly installed in electric vehicles and eventually delivered to users. Over time and with usage, battery problems gradually become apparent. 3. Charging issues: Many new energy electric vehicle owners do not follow proper charging practices, such as using non-compliant charging cables or not using certified charging stations. Over time, this can damage the pure electric vehicle battery, creating safety hazards. This is actually the most common issue, as the charging duration for most pure electric vehicles is currently a concern. In summary, vehicle owners should pay attention to charging standards and use original equipment manufacturer (OEM) accessories when charging their vehicles.
