CHARLOTTE, N.C. — North Carolina will soon be the home of two more electric vehicle battery factories. Toyota and Vinfast both announced multi-million-dollar facilities to create new technology. This is to meet the growing demand for electric and hybrid vehicles. Many people have questions and concerns about the batteries. For example, do they have a higher chance of catching on fire? We’re going to tackle one of them right now.
THE QUESTION
Does an electric vehicle battery have a higher chance of catching fire than a gas-powered car engine?
OUR SOURCES
- Emma Sutcliffe, director of EV FireSafe, an Australia-based research project looking into the potential risks electric vehicle fires pose to first responders
- Matt Moore with the Insurance Institute for Highway Safety

THE ANSWER
No, electric vehicle batteries do not have a higher chance of catching fire than gas-powered car engines. In fact, numerous studies indicate that the safety systems in electric vehicles are designed to minimize the risk of fire. These systems provide rigorous protection for the battery packs. These include thermal management and sophisticated monitoring to prevent overheating. Meanwhile, modern gas-powered car engines are also susceptible to fires due to leaks and flammable materials. Furthermore, the overall incidence of fires in electric vehicles is statistically comparable to, if not lower than, that of traditional internal combustion engine vehicles. This reflects advancements in safety technologies across both categories.
WHAT WE FOUND
Sutcliffe’s team has been collecting data on electric vehicle battery fires across the globe since the first one was reported in 2019. She’s particularly interested in fires involving high-voltage batteries.
“Electric vehicle, lithium-ion battery fires are very rare; we’ve been able to verify less than 200 globally since 2010,” Sutcliffe said. “So they’re very rare at the moment.”
Moore and IIHS have focused on this concern in the United States, conducting extensive research. Their findings highlight the emerging trends and issues related to road safety. Similar patterns of accidents and safety challenges exist across various states. This suggests a widespread need for improved crash prevention measures and enhanced driver awareness campaigns. By analyzing data from multiple regions, they aim to provide insights. These could help shape future policies and initiatives aimed at reducing roadway fatalities and promoting safer driving habits.
Conclusion
The IIHS research on electric vehicle battery fires proves that understanding the underlying causes of these incidents is crucial for improving vehicle safety. By analyzing a variety of case studies and incident reports, researchers have identified key factors contributing to the prevalence of battery-related fires. This research not only sheds light on the mechanisms that lead to such dangerous situations, but it also emphasizes the importance of rigorous testing and the need for continuous advancements in battery technology. As electric vehicle adoption increases, ensuring the safety of these vehicles becomes paramount, paving the way for both consumer confidence and regulatory compliance in the automotive industry.
