What are the causes of electric vehicle spontaneous combustion?
2 Answers
Electric vehicle spontaneous combustion can be attributed to internal and external factors, as detailed below: Internal factors: With prolonged use of electric vehicles, the wiring connections inside the car are prone to aging and short-circuiting. If a short circuit occurs in the internal wiring, it can easily lead to combustion. Additionally, batteries that have been used beyond their lifespan or installed improperly can also cause spontaneous combustion. External factors: Overcharging is another major cause of electric vehicle spontaneous combustion. Many users, for convenience, leave their electric vehicles charging overnight, for 12 hours or even longer. This practice not only fails to yield positive results but also degrades battery performance.
When it comes to the causes of EV fires, I believe the main issue lies in battery system risks. Modern EVs rely on lithium-ion batteries, which can experience thermal runaway—a short circuit within the battery causing temperatures to skyrocket and trigger fires—when exposed to high heat or manufacturing defects. Electrical wiring problems, such as short circuits or aging insulation, can also cause sparks when current shorts. Improper charging is another major concern; using non-OEM chargers or overcharging can overload the battery. External factors like collision damage can directly compromise the battery pack. Software glitches shouldn’t be overlooked either, as system errors may mishandle current control. For prevention, I recommend regular battery inspections without delay, parking in shaded areas during hot weather, and using only manufacturer-approved charging equipment. While EV safety tech is advancing, user vigilance remains crucial.
