285. The Hidden Role of Battery Vents in EV Safety and Adoption

One failure can reshape public trust in EVs overnight. That’s why every detail matters—and why collaboration across the entire EV ecosystem is critical.   Even small components like battery pack vents play an outsized role in preventing thermal runaway events, explosions, and fires. The SAE Battery Pack Venting Committee understands this challenge and answered the call with the new SAE J3325™ Technical Information Report—a guide to designing, testing, and integrating battery vents that perform when it matters most.   To dive deeper, we spoke with Dr. Michael Harenbrock, Principal Expert of Electric Mobility at MANN+HUMMEL GmbH, and chair of the SAE Battery Pack Venting Committee, about how SAE J3325 is helping engineers enhance EV battery safety—and how their work evolves to keep pace with emerging ventilation technologies and trends.   Want to help shape the future of EV safety?
