Key Updates in Electric Aircraft Battery Safety Regulations
Technical Safety Mandates
Certification Frameworks
Logistics & New Chemistries
Thermal No-Propagation (DO-311A) Mandate
Advanced Venting & Containment
Predictive Health Monitoring (BMS)
A single-cell thermal runaway event must not propagate to adjacent cells.
Enhanced requirements for managing toxic off-gassing away from critical aircraft structures.
Shift from reactive safety to predictive "State of Health" monitoring requirements. Not mandatory
EASA MOC-4 & MOC-5 (July '25)
FAA Harmonization
Standardized Means of Compliance for VTOL Energy Storage Systems, replacing ad-hoc "issue papers."
Shifted toward aligning with EASA SC-VTOL standards to streamline dual-certification paths.
Sodium-Ion Inclusion (IATA/ICAO) Introduction of specific UN codes (e.g. UN 3551) allows legal transport and testing of Na-Ion prototypes.
Mandatory 30% SoC Shipping Limit Strict enforcement for air transport of all lithium and sodium-based batteries to mitigate fire intensity.
