How Better Battery Vents Are Powering Safer Electrification

EV safety hinges on the reliability of every component—especially those related to the battery system. Failures, even in small parts like battery pack vents, can significantly impact public trust by triggering dangerous events such as thermal runaway, fires, or explosions. Recognizing this, the SAE Battery Pack Venting Committee developed the SAE J3325™ Technical Information Report. This guide supports engineers in designing, testing, and integrating effective battery venting solutions to enhance EV battery safety. Dr. Michael Harenbrock of MANN+HUMMEL, who chairs the committee, highlights how this collaborative effort is critical in adapting to new ventilation technologies and ensuring the electrification ecosystem evolves safely.
