Chevrolet Equinox EV of the year 2024 suddenly caught fire, creating a frightening situation for the owner, and it was immediately apparent that an emergency was at hand.
A 2024 Chevrolet Equinox battery electric vehicle caught fire on a roadway in Boston this week, causing a significant delay for drivers and requiring multiple fire vehicles and hours to make safe. The fire, which occurred in open air, allowed firefighters to tap into a local fire hydrant on an adjacent street.
The incident highlighted the unique challenges firefighters face when dealing with electric vehicle (EV) fires. Unlike conventional vehicle fires, EV fires, particularly those involving lithium-ion batteries, can reach extremely high temperatures, often exceeding 800°C during thermal runaway events, and can persist for hours, resisting traditional water-based fire suppression methods.
Key reasons for the increased difficulty include thermal runaway and propagation, high temperatures and toxic gas release, resistance to conventional extinguishing techniques, and safety and access challenges. When one cell undergoes thermal runaway, it can rapidly propagate heat and fire to adjacent cells, causing a chain reaction within the battery pack that reignites even after initial suppression efforts.
The Equinox EV fire was initially put out by a Massachusetts State Trooper using a fire extinguisher. However, the driver, Brian, expressed apologies for the traffic disruption caused by the fire, acknowledging the inconvenience it may have caused to other road users.

While the Equinox EV is a big hit for General Motors and the third-best-selling EV in America today, the fire incident has prompted the Chevrolet design team to likely analyse the batteries to determine if additional protection for the battery pack is necessary.
Electric vehicle fires are a growing concern as they become more prevalent, and there is currently no great way of putting them out. As the technology advances, it is crucial for manufacturers to prioritise battery safety to ensure the continued growth and acceptance of electric vehicles.
It is worth noting that Tesla, a pioneer in the electric vehicle industry, faced similar fires when the Model S debuted about twelve years ago. Tesla modified the Model S design to include shields for its battery pack, a move that helped reduce the problem of fires and satisfied a NHTSA probe into the vehicle's design.

- The increasing prevalence of electric vehicles (EVs) has brought attention to the unique challenges firefighters face when responding to EV fires, such as the one involving a 2024 Chevrolet Equinox in Boston, which reached high temperatures and persisted for hours.
- Traditional water-based fire suppression methods are often ineffective against EV fires, particularly those involving lithium-ion batteries, making it crucial for manufacturers to prioritize battery safety in the automotive industry.
- In the aftermath of the Equinox EV fire, the Chevrolet design team may analyze the batteries to determine if additional protection for the battery pack is necessary to address the risk of thermal runaway and propagation, high temperatures, and toxic gas release.
- According to John Goreham, a prominent figure in the automotive and motor press industries, continued research and development are essential to improve battery safety and make EVs a safer and more reliable choice for consumers.
- Tesla, an early player in the electric vehicle (EV) industry, initially faced fires in the Model S, prompting the company to include shields for the battery pack in the vehicle's design, thereby reducing the risk of battery fires and addressing safety concerns.
