EV Fire vs. Gasoline Fire: Temperature, Duration, and Suppression Differences

Understanding the fundamental differences between electric vehicle and gasoline fires is critical for emergency responders, facility managers, and safety professionals as EV adoption accelerates worldwide.

Electric vehicle fires present fundamentally different challenges compared to traditional gasoline vehicle fires, creating unprecedented demands on emergency response systems and safety infrastructure. While EVs statistically catch fire far less frequently than gasoline vehicles, when incidents do occur, they expose critical gaps in our current firefighting capabilities and safety protocols.

A Growing Global Crisis: Recent EV Fire Incidents

Map highlighting recent incidents involving lithium-related fires around the world, including a battery container fire in Canada, a battery storage facility fire in the USA, an EV fire affecting vehicles and households in South Korea, and a data center blaze in Singapore. India, China, and other nations also report significant lithium fire events.

EV fire incidents are escalating globally, transforming from isolated occurrences into a systematic safety crisis that demands immediate attention. Recent years have witnessed a surge in high-profile incidents that expose the devastating potential of lithium-ion battery fires.

The August 2024 underground parking garage fire in Incheon, South Korea, stands as a stark example of this growing threat. When a Mercedes-Benz EQE spontaneously combusted, it destroyed nearly 900 vehicles, displaced 700 residents, and required 8 hours to extinguish. This single incident caused massive infrastructure damage and highlighted the cascading risks of EV fires in confined spaces.

This wasn't an isolated event. Tesla has documented 232 fire incidents with 83 fatalities through February 2024, while maritime transport has faced unprecedented challenges. In June 2025, the cargo ship Morning Midas was abandoned off Alaska after EV fires on deck proved uncontrollable, forcing the Coast Guard to rescue 22 sailors. Earlier incidents include the 2023 Fremantle Highway fire in the Netherlands, which destroyed 3,000 cars, and the 2022 Felicity Ace fire in Germany, where 4,000 Volkswagen vehicles were lost.

South Korea alone experienced 72 EV fires in 2023—a 200% increase from 2021—prompting major insurers like State Farm to remove all EV charging stations from their parking facilities nationwide. The UK has documented 239 EV fire incidents, representing an 83% year-over-year increase, while European projections show incidents rising from 5,194 expected in 2025 to 13,655 by 2030.

Temperature: The Extreme Heat Challenge

[VISUAL AID SUGGESTION: Temperature comparison chart with thermometer graphics showing 4,500°F for EV fires vs 1,500°F for gasoline fires, with melting points of common materials for context]

Comparison of fire temperatures: Gasoline fires can reach 1,500°F (815°C), while EV battery fires can soar up to 4,500°F (2,500°C).

EV Battery Fires: Up to 4,500°F (2,500°C)

EV fires burn at temperatures exceeding 4,500°F (compared to 1,500°F for gasoline fires), creating conditions that overwhelm traditional firefighting equipment and tactics. These extreme temperatures result from thermal runaway—a chain reaction where damaged lithium-ion battery cells generate heat that triggers adjacent cells to fail, creating an unstoppable cascade of energy release.

During thermal runaway, battery cells can reach internal temperatures exceeding 1,000°C before venting flammable gases. When these gases ignite, they create flame temperatures that can melt aluminum components and compromise structural integrity far beyond what traditional vehicle fires achieve.

Gasoline Fires: 1,500°F (815°C)

Traditional gasoline fires, while dangerous, burn at predictable temperatures around 1,500°F. Fire departments have decades of experience managing these conditions with established suppression techniques, foam applications, and cooling strategies that prove effective within established timeframes.

Duration: Minutes vs. Hours

[VISUAL AID SUGGESTION: Timeline comparison showing gasoline fire resolution in 15-30 minutes vs EV fire operations extending 7+ hours, with personnel allocation visualization]

Comparison of Fire Duration: Gasoline vehicle fires typically last 15-30 minutes, while electric vehicle fires can extend beyond 7 hours.

EV Fire Duration: Extended Operations

Fire departments must maintain continuous water flow for hours, not minutes, while monitoring for reignition that can occur days or even weeks later. The International Association of Fire Chiefs now requires departments to secure "large, continuous and sustainable water supply" and maintain "sufficient fire personnel and apparatus on scene for an extended operation."

EV fires can smolder for hours even after apparent suppression, with battery cells continuing to generate heat and toxic gases. A single EV fire can require 14+ firefighters compared to 3-4 for traditional vehicles, straining departments already facing staffing challenges.

Gasoline Fire Duration: Rapid Resolution

Gasoline fires typically reach peak intensity quickly and can be suppressed within 15-30 minutes using conventional techniques. Once the fuel source is eliminated or suppressed, the fire generally stops, allowing crews to focus on overhaul and investigation rather than extended suppression operations.

Water Requirements: Exponential Increase

[VISUAL AID SUGGESTION: Water usage comparison using fire truck graphics - single truck (500 gallons) for gasoline vs multiple tanker trucks (3,000-40,000 gallons) for EV fires]

Comparison of water usage for fire suppression shows a stark contrast between traditional vehicles and electric vehicles. Traditional vehicles require 300-500 gallons, while electric vehicles need 3,000-40,000+ gallons.

EV Suppression: 3,000-40,000+ Gallons

Where a typical car fire requires 300-500 gallons of water, EV fires demand 3,000 to 40,000 gallons—with one Sacramento Tesla fire consuming 4,500 gallons. These massive water requirements often exceed the capacity of single fire apparatus, requiring multiple tanker trucks and extended supply operations.

Some documented cases show even higher consumption:

• Tesla fire in Stamford: 24,000 gallons over 40 minutes

• Electric semi-truck (NTSB): 50,000 gallons for complete suppression

Traditional Vehicle Suppression: 300-500 Gallons

Gasoline vehicle fires can typically be suppressed with the water carried on a single fire engine, usually requiring 300-500 gallons total. This allows for rapid response without the logistical challenges of establishing water supply operations or coordinating multiple apparatus.

Toxic Gas Production: A Hidden Danger

Hazard Alert: Breakdown of electrolytes and battery materials releases over 100 toxic compounds, including hydrogen fluoride, hydrogen cyanide, carbon monoxide, and other harmful organic compounds.

EV Fire Emissions: Complex Chemical Cocktail

EV fires produce hydrogen fluoride concentrations 60-80% higher than traditional vehicle fires, and create toxic smoke requiring full hazmat protocols. The breakdown of electrolytes and battery materials releases over 100 different compounds, including:

• Hydrogen fluoride (HF) - extremely corrosive and toxic

• Hydrogen cyanide - lethal in small concentrations

• Carbon monoxide - odorless and dangerous

• Various organic compounds from plastic and electronics

Gasoline Fire Emissions: Predictable Hazards

While gasoline fires produce dangerous smoke containing carbon monoxide and other combustion products, the chemical composition is well-understood. Fire departments have established protocols for managing these hazards without requiring specialized hazmat response for every incident.

Reignition Risk: The Persistent Threat

EV Batteries: Days or Weeks of Monitoring

Perhaps the most challenging aspect of EV fires is their tendency to reignite. 13% of EV fires reignite, with documented cases up to 68 days later. This requires damaged EVs to be quarantined in isolation areas with 50-foot separation distances and continuous monitoring—a logistical nightmare for departments and towing companies.

Battery cells can appear dormant while retaining enough energy to restart thermal runaway when disturbed by movement, temperature changes, or continued internal chemical reactions. This unpredictability forces departments to treat every EV fire as a potential long-term incident.

Gasoline Vehicles: Minimal Reignition Risk

Once a gasoline fire is suppressed and hot spots are extinguished during overhaul, reignition risk is minimal. Vehicles can typically be moved and processed normally without extended monitoring periods.

Resource Allocation Impact

The resource intensity of EV fires creates cascading effects on emergency services:

Personnel Requirements:

• A single EV fire can require 14+ firefighters compared to 3-4 for traditional vehicles

• Extended operations lasting 7+ hours versus 30-60 minutes

• Specialized training requirements for only 300,000 of 1.1 million U.S. firefighters

Equipment Demands:

• Multiple apparatus for water supply operations

• Specialized PPE for toxic gas exposure

• Extended air supply for prolonged operations

• Isolation and monitoring equipment for post-incident management

While EVs offer significant environmental benefits and lower fire frequency, the unique characteristics of battery fires—extreme temperatures, extended duration, massive water requirements, toxic emissions, and reignition risks—create challenges that traditional firefighting methods cannot adequately address.

Understanding these differences is the first step toward developing effective solutions. As demonstrated by cutting-edge suppression technologies, the industry is responding with innovations that can address EV fire challenges while supporting the continued growth of electric transportation. However, widespread implementation of these solutions remains critical as we transition to an electric future.

The question isn't whether EVs are safer by pure statistics—it's whether our communities are prepared for the unique, resource-intensive emergencies they create. Current evidence suggests we're far from ready, making investment in advanced fire suppression technology not just beneficial, but essential.
