§561.10. Documentation for single cell thermal runaway and propagation safety risk mitigation. — Inbound Citations

Each applicable manufacturer shall maintain the information specified in §§ 561.7 through 561.10 for the documentation requirements for a period of five years from the date of manufacture.

(1) Vehicles with a gross vehicle weight rating of 4,536 kilograms (kg) or less manufactured on or after September 1, 2027, are subject to §§ 561.7 through 561.10.

(e) This part of the documentation summarizes the vehicle design and manufacturing strategies and their validation to mitigate the safety risks associated with thermal propagation due to single cell thermal runaway resulting from internal short within a cell. This part shall include a description of the final manufacturer review/audit process and results of the final review or audit evaluating the technical content and the completeness and verity of paragraphs (a) through (d) of this section.
