What Happens When An Electric Vehicle Is on Fire? The Process of Electric Vehicle Fire

There is a lot of controversy over the stability of electric vehicle batteries due to the fire of Mercedes-Benz electric car. Let's see how it can be dangerous if an electric car catches fire through AI.

Why Electric Vehicle Batteries

Are on Fire The main reasons for electric car batteries to catch fire are as follows: Damage to battery cells: Damage to battery cells due to impact or physical damage can cause an internal short circuit. This can trigger a chemical reaction inside the battery, increasing heat generation, which can eventually lead to a fire. Overheating: If the battery is exposed to high temperatures, internal lithium ions can become unstable. This overheating can occur during charging, and if the battery management system (BMS) is not working properly, the overheating can be uncontrolled and a fire can occur. Overcharging: Overcharging the battery can cause the internal voltage to rise rapidly, resulting in a phenomenon called thermal runaway. This can cause the electrolyte in the battery to gasify, which can lead to an explosive fire. Manufacturing defect: A defect or defect in the manufacturing process of the battery itself can cause problems with the internal structure of the battery, which can lead to the battery becoming unstable during use and leading to a fire. External short circuit: Short circuits outside the battery pack or wiring can cause the battery to emit abnormal high current, which can lead to overheating and fire. External Factors: Collisions, physical damage to the battery, penetration of external substances, etc. can also cause battery fires. For these reasons, technology is continuously being developed to enhance the safety of electric vehicle batteries. Examples include battery management systems (BMSs), cooling systems, and safe charging protocols.

What happens if an electric car catches fire

When an electric vehicle catches fire, it has different characteristics from those of a typical internal combustion engine vehicle, and special care is required to deal with it. In the event of an electric vehicle fire, the following can occur. 1. Thermal runaway of the battery The lithium-ion battery of an electric vehicle can cause thermal runaway by accelerating its internal chemical reaction when heat increases. This can lead to a fire or explosion as the temperature inside the battery rises uncontrollably. If the battery pack is damaged or overheated, the internal cells can explode in a chain and the fire can spread rapidly. 2. Difficulties in Combining Fire Electric vehicle fires are much more difficult to extinguish than conventional vehicle fires. Chemical fires that occur inside the battery are not easily extinguished by water or fire extinguishers. Electric vehicle batteries can catch fire again after several hours due to the remaining heat inside. This is why monitoring is necessary even after the fire has been completely extinguished. 3. Toxic Gas Generation In the event of a battery fire, toxic gases can be generated by burning chemicals inside the battery. In particular, lithium-ion batteries can release harmful gases, such as fluorine compounds, which requires safety measures at the scene of the fire. 4. Risk of Vehicle Damage and Explosion If a fire spreads, the entire vehicle may be damaged and there is a risk of battery explosion. An explosion can cause great damage to the surroundings of the vehicle. 5. Action After a Fire Even after an electric vehicle fire is extinguished, the vehicle needs special treatment. To prevent reoccurrence, the vehicle should be moved to a safe place and the battery condition should be continuously monitored. Batteries and vehicles that are on fire should be handled safely, and a thorough investigation into the incident is carried out. 2. How to deal with a fire Quickly get out of the vehicle: Get out of the vehicle when a fire breaks out, and escape safely. Call emergency services: Call 119 or emergency services to notify them of the fire and ask for help. 3. Do not attempt to put out a fire: It is important to leave it to a professional because it is difficult to extinguish an electric car battery fire with a typical fire extinguisher or water. 4. Maintain a safe distance: Due to the risk of an explosion, you should keep it away from vehicles and at a safe distance. Electric vehicle fires can be more complex and dangerous than regular vehicle fires, so it is important to be prepared for these situations.
