SAE releases recommended practice for safe battery testing

SAE International has released SAE J2464: Electric and Hybrid Electric Vehicle Rechargeable Energy Storage System (RESS) Safety and Abuse Testing, a revised recommended practice for establishing safe battery systems. Originating in 1999 when the industry recognized the need for safety and abuse testing of battery systems in the mobility sector, the revised J2464 recommended practice expands to focus on electric and hybrid vehicles.

J2464 describes a body of tests that can be used for abuse testing of electric or hybrid electric vehicle RESS to determine the response of the storage and control systems to conditions or events which are beyond their normal operating range.

Abuse test procedures in the document are intended to cover a broad range of vehicle applications and storage devices, including individual RESS cells (batteries or capacitors), modules and packs. The document specifically applies to vehicles with RESS voltages above 60 volts.

“As the electrification era is in full swing, SAE J2464 serves as an important anchor for establishing safe and effective battery systems, even when abused,” said Bob Galyen, Chair of the SAE Vehicle Battery Standards Steering Committee. “The revised version of this document will bring it up to present technology standards to serve the mobility sector and advancements in the years ahead.”
