1. Summary

  • The report titled 'Electric Vehicle Fire Prevention: Safety Guidelines and Awareness Initiatives' examines current efforts to enhance safety measures against electric vehicle (EV) fires, particularly those involving lithium-ion batteries. Fire departments like Chilgok, Gunsan, and Gyeongju have highlighted the risks associated with lithium-ion batteries, especially during charging. The report discusses fire prevention strategies such as proper charging practices, the importance of using designated chargers, avoiding moisture during charging, and ensuring each EV is equipped with a fire extinguisher. Additionally, it emphasizes the role of public education and awareness campaigns in mitigating fire risks associated with EVs and their charging facilities.

2. Introduction to EV Fire Risks

  • 2-1. Increasing Concern over EV Fires

  • There is a growing concern regarding electric vehicle (EV) fires due to the rising use of lithium-ion batteries. Multiple fire departments, such as Chilgok Fire Station and Gunsan Fire Station, have highlighted the risks associated with EVs, particularly during charging. As electric vehicles become more common, the potential for fire risks increases, prompting fire safety initiatives.

  • 2-2. Key Causes of EV Fires

  • The causes of EV fires primarily relate to the lithium-ion batteries they utilize. These fires can occur due to overheating, battery defects, and external impacts to the battery. A specific phenomenon of concern is 'thermal runaway,' where the battery temperature can rapidly rise to over 1,000°C during a fire, making it difficult to extinguish and leading to a high risk of re-ignition. The Chilgok Fire Station has identified several safety rules to mitigate these risks, such as avoiding charging with wet hands, using only designated chargers, prohibiting smoking near charging stations, and keeping fire extinguishers in vehicles. The Gunsan Fire Station also emphasized precautions, such as preventing damage to battery packs from obstacles and ensuring appropriate charging levels.

3. Detailed Safety Guidelines for EV Fire Prevention

  • 3-1. Proper Charging Practices

  • Proper charging practices are crucial to prevent electric vehicle (EV) fires. Users are advised not to charge their EVs with wet hands or when in contact with moisture. It is imperative to use only the designated chargers and adapters to avoid overheating and potential battery malfunctions. Smoke-free zones around charging stations are also emphasized to further reduce fire risks.

  • 3-2. Specific Safety Measures for Users

  • Users should be aware of specific safety measures to mitigate the risk of EV fires. These include the necessity of having a fire extinguisher within the EV, with recommendations stating that every vehicle should be equipped with at least one fire extinguisher. Awareness of the risks associated with lithium-ion battery overheating, particularly during charging, is critical for all EV owners. Public education initiatives underscore the significance of understanding these hazards to promote safe usage.

  • 3-3. Mandatory Equipment and Precautions

  • Mandatory precautions include having effective fire suppression equipment readily accessible in case of emergencies. Education campaigns led by fire departments stress the need for personal fire extinguishers and adherence to recommended safety practices to combat the unique challenges associated with lithium-ion battery fires, such as high-temperature thermal runaway incidents.

4. Case Studies and Incidents

  • 4-1. Case Study: Gyeongju EV Fire Incidents

  • Gyeongju Fire Department, led by Chief Jo Yoo-hyun, has initiated efforts to promote fire prevention measures due to the increasing incidents of electric vehicle (EV) fires. Over the past five years, there have been four reported EV-related fires in Gyeongju. These fires have demonstrated that suppression of EV fires can be quite challenging due to various ignition sources such as overheating, battery defects, and collisions. A significant concern is overheating, particularly during the charging process, underscoring the need for users to recognize the potential risks associated with EV charging. To mitigate the risk of fires, Gyeongju Fire Department highlights preventive measures which include the following: charging should not be done with wet hands or when the user is damp, only certified chargers and adapters should be used, smoking is prohibited near charging stations, and each vehicle must have at least one fire extinguisher on board.

  • 4-2. Challenges in Fire Suppression

  • The challenges in suppressing EV fires stem from the unique properties of lithium-ion batteries. Notably, these batteries can pose significant hazards during incidents of thermal runaway, where a battery overheats and can lead to explosions. The Gyeongju Fire Department has emphasized that a deep understanding of the causes of EV fires and the right techniques for addressing them is essential for effective fire management. Given that traditional firefighting methods may not always be suitable, there is a pressing need for specialized training and preparation among first responders. Moreover, continued education for the public on the risks associated with EVs and appropriate safety measures is critical for minimizing incidents.

5. Ongoing Education and Public Awareness

  • 5-1. Public Awareness Campaigns

  • The Chilgok Fire Station has initiated a campaign to promote the 'four safety guidelines' aimed at preventing fires in electric vehicle (EV) charging facilities. This initiative comes in response to growing concerns about fire risks associated with EVs. The fire department highlights that EVs utilize lithium-ion batteries, which can ignite due to overheating, battery defects, or external impacts. Notably, battery fires can result in temperatures exceeding 1000°C, making them challenging to extinguish and creating high risks for re-ignition. The four safety guidelines stressed by the Chilgok Fire Station are: 1) Do not charge with wet hands or in wet conditions, 2) Always use designated chargers and adapters, 3) No smoking in the vicinity of charging stations, and 4) Ensure that a vehicle-mounted fire extinguisher is available.

  • 5-2. Role of Fire Departments in Education

  • The Gyeongju Fire Station is actively promoting fire prevention methods related to electric vehicles to reduce risks of injury from EV-related fires. Over the past five years, Gyeongju experienced four incidents of EV-related fires, highlighting the challenges of extinguishing such fires and the necessity of understanding their causes and prevention methods. The fire department points out that overheating during the charging process is a particular concern and urges users to remain vigilant about these risks. Recommended preventive measures include: 1) Never charge with wet hands or in wet conditions, 2) Use only designated chargers and adapters, 3) Prohibit smoking near charging stations, and 4) Equip each vehicle with a fire extinguisher.

6. Conclusion

  • The report underscores the critical importance of adhering to safety guidelines to mitigate the risks of electric vehicle fires, particularly those related to lithium-ion batteries and thermal runaway. Key recommendations include proper charging practices, use of designated chargers, and ensuring that fire extinguishers are present in every vehicle. Fire departments in Chilgok, Gunsan, and Gyeongju have played a pivotal role in educating the public and promoting these safety measures. However, the report also highlights that traditional fire suppression methods are often insufficient for EV fires, necessitating specialized training for first responders. Despite these efforts, further work is needed to address the inherent challenges of lithium-ion battery fires and enhance public awareness continually. Future initiatives should focus on advancing safety technologies and widespread education to secure the safe and reliable use of electric vehicles.
