In the rapidly evolving landscape of commercial electric vehicles, battery safety testing is a critical cornerstone of sustainable and safe transportation. Proterra, a proven electrification partner for heavy-duty transportation and equipment manufacturers, is powering the shift in battery safety through an integrated approach that combines innovative design with rigorous testing protocols.

Engineering Safety from the Ground Up

Safety is embedded in our battery’s design from the very beginning, meticulously engineered into every detail, and never treated as an afterthought. This comprehensive approach combines active monitoring systems with robust physical protection, creating multiple layers of defense against potential issues.

The active safety systems function as a sophisticated nervous system, constantly monitoring battery health through an advanced Battery Management System. This network of sensors and algorithms vigilantly tracks temperature, voltage, and other critical parameters, responding instantly to any anomalies. Meanwhile, passive safety features provide physical protection through carefully engineered structures and innovative thermal management systems.

Beyond the Standard

What truly distinguishes Proterra’s approach is the commitment to rigorous testing that exceeds industry standards. Our validation protocols simulate extreme real-world conditions, including vibration testing that replicates one million miles of road wear and unique underside strike testing that verifies protection against road debris impacts.

In a propagation resistant design like Proterra’s, when one cell experiences a heat-related event, the event stays isolated. This protection works regardless of whether the vehicle is powered on or off. It’s a passive safety feature – always on guard, always working.

Powering the Shift

As electric vehicles become increasingly central to our transportation future, the importance of battery safety continues. Proterra’s comprehensive approach demonstrates how thoughtful engineering, and thorough testing can create battery systems that are both sustainable and safe. Proterra means “For the Earth” reflecting a commitment to developing sustainable transportation solutions without compromising safety.

The innovations emerging from Proterra’s commercial applications have broad implications for the entire industry. Our work represents more than technological progress—it’s about creating a foundation for safe, sustainable and reliable transportation that benefits communities worldwide.
