Crashed electric cars: what happens to the batteries?
In an interview with Reuters, Matthew Avery, research director at Thatcham Research, expressed concern about crashed electric cars. According to Avery, in many cases, there is no way to repair or assess damaged battery packs, forcing insurance companies to scrap even low-mileage vehicles, resulting in a significant increase in insurance premiums.

What is stranded energy in electric vehicle batteries?
Call for a collaborative effort of researchers, OEMs, and policymakers. In post-crash situations, passengers, bystanders, and first responders are exposed to the immediate safety risks of stranded energy in electric vehicle (EV) batteries. Stranded energy is the energy remaining inside any undamaged or damaged battery following an accident.
What are the risks of a damaged battery?
A further risk is that damaged cells in the battery can experience thermal runaway – uncontrolled increases in temperature and pressure – which can lead to battery reignition. The risks of electric shock and battery reignition/fire arise from the “stranded” energy that remains in a damaged battery.
Can you store an electric vehicle with a damaged battery?
Storing an electric vehicle with a damaged high-voltage lithium-ion battery is an additional problem.” The battery fires investigated by the NTSB reignited multiple times, even days after a crash, placing other vehicles and nearby structures at risk for fire. The Chevrolet Volt that reignited 3 weeks after a crash test damaged four nearby vehicles.
Can a car battery cause a fire?
But the hazard concerns are not limited to just the rescue of the occupants because if the battery has been damaged, stranded energy within the vehicle's battery "may also lead to a fire - days, weeks or even months after the initial incident". But how often do these sorts of incidents occur?
What happened to the lithium-ion batteries?
Three of the lithium-ion batteries that ignited were damaged in high-speed, high-severity crashes, and the fourth lithium-ion battery fire occurred during normal vehicle operations. All three of the crash-damaged batteries reignited after firefighters extinguished the vehicle fires. The battery in the fourth investigation did not reignite.
Are battery cells a payback if a car crashes?
As payback, however, there are certain restrictions. One reason for this practice is that too little research has been done into the behaviour of battery components under crash conditions, such as battery cells," explains Wolfgang Sinz from the Institute of Vehicle Safety at TU Graz.
