Honda, Hyundai, Volkswagen & more EV makers adopt US govt`s recommendation on battery fires
US government has issued guidelines on battery fire to EV makers. Currently, 8 brands have adopted the government`s guideline, while more are yet to follow the suit.
Highlights
- US NTSB issues guidelines to EV makers for battery fire
- Carmakers like Honda, Hyundai, VW and more have adopted the guidelines
- Twelve more manufacturers are progressing to adopt these guidelines
US National Transportation Safety Board (NTSB) has issued guidelines to electric car makers on improving emergency response guidelines, along with incorporating vehicle-specific information to curb high-voltage lithium-ion battery fires. Eight EV makers have adopted this recommendation, namely Honda, Hyundai, Mitsubishi, Porsche, Proterra, Van Hool, Volkswagen and Volvo. These brands have completed the actions asked by NTSB, the agency said in a statement.
NTSB issued the recommendation in January 2021 to 22 electronic car manufacturers.
Twelve manufacturers (BMW, BYD, Stellantis, formerly Fiat Chrysler Automobiles US, Ford, General Motors, Gillig, Kia, Mercedes-Benz, Nissan, Subaru, Tesla and Toyota) are making progress on the steps identified in the recommendation.
Two manufacturers, Nova Bus Corporation and Karma Automotive, have not yet responded.
"First responders deserve to have the information they need to stay safe when providing post-crash care -- and that includes knowing how to suppress a high-voltage lithium-ion battery fire," said Chair Jennifer Homendy.
"Our recommendation is a simple but powerful action that can save the lives of first responders and crash victims alike. I congratulate the eight electric vehicle manufacturers that have stepped up and call on the remaining 14 companies to implement our recommendation immediately," Jennifer added.
The recommendation was issued over two main safety issues.
The first issue is the inadequacy of vehicle manufacturers` emergency response guides and the second is gaps in safety standards and research related to high-voltage lithium-ion batteries involved in high-speed, high-severity crashes.

Fires in electric vehicles powered by high-voltage lithium-ion batteries pose the risk of electric shock to emergency responders from exposure to the high-voltage components of a damaged lithium-ion 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," said the US agency.
The risks of electric shock and battery reignition/fire arise from the "stranded" energy that remains in a damaged battery.
