EV and HEV Rechargeable Energy Storage System Safety and Abuse Testing
SAE J2464 defines safety and abuse test procedures for rechargeable energy storage systems (RESS) used in electric and hybrid electric vehicles. It provides a comprehensive set of mechanical, thermal, and electrical abuse tests at the system level to characterise the failure modes and hazard severity of battery systems under conditions outside normal operating limits.

Scope
SAE J2464 applies to complete RESS (battery pack and system) for EV and HEV applications. Unlike prescriptive pass/fail safety standards, J2464 is a characterisation standard — tests are performed to understand what happens when limits are exceeded, rather than to demonstrate compliance with minimum safety thresholds. Results inform risk assessment and hazard classification.
Key Test Categories
Mechanical Abuse Tests
Tests include penetration by a conductive rod (nail penetration at system level), crushing, rollover simulation (3-axis inclination), and submersion. These tests assess the system’s response to physical damage scenarios including accident conditions.
Thermal and Electrical Abuse
Thermal abuse includes fire exposure and thermal ramp to assess system response as temperature rises above the operating range. Electrical abuse tests include external short circuit, overcharge, and forced over-discharge, characterising the system’s response when BMS protections are bypassed.
