Electric Vehicle (EV) Battery Safety Research and Support

The National Highway Traffic Safety Administration (NHTSA) established the Battery Safety Initiative for Electric Vehicles (Initiative) to coordinate research and other activities relating to electric vehicle (EV) battery safety. The Initiative is responsible for:

• Collecting and analyzing data related to EV batteries;
• Examining field incidents and conducting battery safety investigations from EV crash and non-crash events;
• Researching and evaluating EV battery health, battery management systems and cybersecurity, and high-voltage battery charging failures and effects; and,
• Investigating safety-related battery defects.

The NHTSA Initiative also participates in the development of Global Technical Regulation (GTR) No. 20 for EV Safety which includes battery fire safety. For more information, see the NHTSA’s Initiative website.
