Introduction
EV battery fire risks may be rare, but they can escalate quickly if overlooked. As electric vehicles gain popularity in Malaysia and globally, understanding the potential fire hazards associated with lithium-ion batteries is critical for every EV owner. Prevention and early detection are your best defenses.
Common EV Battery Fire Risks and Safety Tips
1. Thermal Runaway
Thermal runaway occurs when a battery cell overheats and triggers a chain reaction of nearby cells catching fire. It often happens due to overcharging or internal damage. Always monitor battery temperature, especially during charging.
2. Battery Damage from Accidents
While EV battery packs are built to be durable, physical impact can compromise their integrity. After any accident—minor or major—get the battery pack professionally inspected for leaks, swelling, or cracks.
3. Unsafe Charging Practices
Always use manufacturer-certified chargers and cables. Avoid cheap third-party products that may lack overcurrent or temperature protection. Overheating while charging is a major EV fire risk.
4. Poor Ventilation in Parking Areas
Park your EV in well-ventilated spaces. Charging in closed garages without airflow can trap heat and gases. Installing carbon monoxide and smoke detectors is highly recommended.
5. Outdated EV Software
Manufacturers frequently release firmware updates to optimize battery performance and prevent overheating. Ensure your EV receives regular software updates.
6. Extreme Temperature Exposure
Avoid leaving your EV charging in direct sunlight on hot days, and don’t let the battery drain completely in freezing weather. Both conditions stress battery chemistry and can cause fire hazards.
7. Know Emergency Protocols
If you smell burning plastic, see smoke, or hear popping from the battery compartment, immediately evacuate and call emergency services (e.g., BOMBA 999). Do not attempt to extinguish large EV battery fires yourself.
Bonus Prevention Tip
Keep an EV fire blanket nearby, especially if your vehicle is parked in a garage. These blankets help contain fires in the early stages and reduce oxygen supply. Please refer to instruction on how to use an EV fire blanket.
Conclusion
Understanding EV battery fire risks is key to safe electric vehicle ownership. With responsible habits—like proper charging, timely maintenance, and emergency preparedness—you can significantly lower the chances of battery-related fires. Be proactive, stay informed, and always prioritize safety.
