Why Proterra?
Purpose-Built for Sustainable Power
We’re driving the future of commercial transportation with innovative battery solutions engineered to meet the demands of medium- and heavy-duty vehicles.
Combining proven technology and innovative design, Proterra electric battery solutions have helped countless customers reach their zero-emission goals. We’re ready to do the same for you.
Our battery solutions power vehicles and equipment from world-class manufacturers.
Active & Passive Safety Features
Our battery packs are designed with multiple layers of safety. Active features, such as liquid cooling and intelligent battery management systems, continually monitor battery performance, while passive features like single-cell fault tolerance help isolate potential issues.
High Energy Density
Our focus on high energy density allows us to create batteries for commercial vehicles that travel long distances and carry heavy loads. Top-tier cylindrical cells charge quickly to provide industry-leading energy density for various applications.
Scalable Platform
Our battery packs are designed for a variety of on- and off-road commercial applications, allowing us to meet diverse customer needs and vehicle regulations.
Durability
We build our batteries to last. Each pack delivers reliable power for 8-10 years. Before final inspection, our products undergo in-house vibration, impact, and crush testing to ensure they’re ready to withstand the most demanding conditions.
Serviceability
We design our battery packs with a focus on serviceability to reduce the total cost of ownership and simplify maintenance. All serviceable components are enclosed in the ancillary bay, which is isolated from high-voltage components.
Rigorous Testing
Our state-of-the-art battery production facility, complete with an advanced cell testing lab, enables us to validate each battery system's thermal and electrical performance through in-house cycle testing, safety testing, abuse testing, and characterization testing.
Quality
Excellence engineered into every step — from design to deployment
Rigorous testing at each phase to deliver unmatched performance.
Making the shift to electric shouldn’t require you to compromise on quality. That’s why we take the time to create batteries you can rely on, no matter the distance, load, or conditions.
