Numerous plug-in electric vehicle (EV) fire incidents have taken place since the introduction of mass-production plug-in electric vehicles.[1] As a result of these incidents, the United States Department of Transportation''s National Highway Traffic Safety Administration (NHTSA) conducted a study in 2017 to establish whether lithium-ion batteries in plug-electric vehicles pose an exceptional fire hazard. The research looked at whether the high-voltage batteries can cause fires when they are being charged, and when the vehicles are involved in an accident.[1]

Regarding the risk of electrochemical failure, [this] report concludes that the propensity and severity of fires and explosions from the accidental ignition of flammable electrolytic solvents used in Li-ion battery systems are anticipated to be somewhat comparable to or perhaps slightly less than those for gasoline or diesel vehicular fuels. The overall consequences for Li-ion batteries are expected to be less because of the much smaller amounts of flammable solvent released and burning in a catastrophic failure situation.[1]

The NHTSA in 2021 opened a new Battery Safety Initiative investigation into EV car fires in light of the continuing numerous fire incidents.[2][3]

They were thermal runaway incidents related to the lithium-ion batteries. The brands involved were the Zotye M300 EV, Chevrolet Volt, Fisker Karma, Dodge Ram 1500 Plug-in Hybrid, Toyota Prius Plug-in Hybrid, Mitsubishi i-MiEV and Outlander P-HEV.

A Mitsubishi Outlander fire in May 2019 appeared to be related to immersion in salt water (which is electrically conductive), probably for an hour or two.[citation needed]

General Motors, Nissan and Tesla have published a guide for firefighters, and first responders to properly handle a crashed electric-drive vehicle and safely disable its battery and other high voltage systems.[8][9]

The difference with EV car fires is the use of high voltage lithium-ion batteries which can short and break down and spontaneously combust, and also that lithium-ion fires are difficult to extinguish and produce toxic smoke.[10][11]

Fire incidents in highway-capable vehicles occur relatively frequently (and mostly involve non-PHEV vechicles, at least in the US). A study of U.S. fires from 2003–2007 finds that fire departments respond to an average of 287,000 vehicle fires per year, or 30 vehicle fires per hour, and that vehicles were involved in 17% of all reported U.S. fires.[12] The study also finds that roughly 53 highway vehicle fires and 0.15 highway vehicle fire deaths were reported per billion miles driven.

On October 24, 2019, the National Highway Traffic Safety Administration opened a Defect Petition for Tesla Model S and X vehicles manufactured between 2012 and 2019 related to battery fires not caused by collision or impact.[24][25]

Responding to 2022 questions about the risk of fire and reignition related to contact of li-ion battery with salt water (seawater), as it appeared to happen in Florida following the passage of Hurricane Ian,[26][27] Jack Danielson (executive director of NHTSA) wrote[28][29] that what reported "is not an isolated event". He also quote tests and studies dated 2019[30] and 2021[31] on the subject.

Emerging risks around home charging and the ability to detect and extinguish a fire in a domestic setting are not well understood.

As of August 2021, Electrek had compiled a list of 18 battery-related Chevrolet Bolt fires, and one possible-battery related fire.[37] The frequent fires resulted in a recall of about 110,000 Chevrolet Bolt and Bolt EUV EVs from the 2017 through 2022 model years.[38]

Even after the recall, several fires occurred in vehicles that had received the new software and been checked by a dealer — including one in a vehicle owned by a Vermont state lawmaker.[39] Another fire happened in New Jersey,[39] the company told CNBC. GM says it''s still investigating the fires, and is asking owners who haven''t gotten the fix to take their Bolts in to a dealer regardless. At least nine fires have been documented, and the company has started buying back some Bolts. Moreover, the company recommended that Bolt owners park their cars outside and at least 50 feet away from other vehicles.[40]

On September 13, 2021, a Chevrolet Bolt caught fire in a private garage in Cherokee County, Georgia, USA. The owner had either been unaware or simply ignored the recommendation to park outside.[41]

As a result of a crash-tested Chevrolet Volt that caught fire in June 2011 three weeks after the testing, the National Highway Traffic Safety Administration (NHTSA) issued a statement saying that the agency does not believe the Volt or other electric vehicles are at a greater risk of fire than gasoline-powered vehicles. They added: "In fact, all vehicles –both electric and gasoline-powered – have some risk of fire in the event of a serious crash."[42][43] The NHTSA announced in November 2011 that it was working with all automakers to develop post-crash procedures to keep occupants of electric vehicles and emergency personnel who respond to crash scenes safe.

In further testing of the Volt''s batteries carried out by NHTSA in November 2011, two of the three tests resulted in thermal events, including fire. Therefore, the NHTSA opened a formal safety defect investigation on November 25, 2011, to examine the potential risks involved from intrusion damage to the battery in the Chevrolet Volt.[44][45][46]

In May 2012, after a Nissan GT-R crashed into a BYD e6 taxi in Shenzhen, China, the electric car caught fire after hitting a tree killing all three occupants.[4] The Chinese investigative team concluded that the cause of the fire was that "electric arcs caused by the short-circuiting of high voltage lines of the high voltage distribution box ignited combustible material in the vehicle including the interior materials and part of the power batteries." The team also noted that the battery pack did not explode; 75% of the single cell batteries did not catch fire; and no flaws in the safety design of the vehicle were identified.[59]

On December 29, 2020, a BYD e6 taxi caught fire at an intersection in Luohu District, Shenzhen, China.[60]

In July 2021, Dongchedi (Chinese: ), a ByteDance''s automotive media in China, performed a crash test of BYD Han EV versus Arcfox Alpha-S. Having been parked for 48 hours after the test, only the Han EV caught fire and burned to the ground.[61][62][63]

On June 15, 2022, a BYD Han EV caught fire on a road in Xaysetha district, Vientiane, Laos.[64][65]

On November 15, 2021, a BYD Tang EV caught fire in a workshop in Kristiansand, Norway.[66]

On January 26, 2022, a BYD Tang DM-i (plug-in hybrid) caught fire on a flatbed tow truck, on a road in mainland China. By the such kind of transporting, it seems to be a malfunctioning car.[67]

On May 28, 2020, a BYD Qin Pro EV caught fire at a charging station in Shenzhen, China.[68]
