Proterra Power Unveils “Large Featherlight” – Revolutionizing EV Battery Packs with Unprecedented Density

BURLINGAME, CA – October 26, 2023 – Proterra Powered LLC, a leading innovator in electric vehicle (EV) battery technology, today announced the launch of its “Large Featherlight” battery pack. Based out of Burlingame, California (1815 Rollins Rd, 94010-2204, and reachable at 254-542-8622), Proterra has been quietly building a reputation for pushing the boundaries of what's possible in EV energy storage. This new pack isn’t just an incremental improvement; it's a game-changer designed to significantly extend EV range, reduce vehicle weight, and ultimately accelerate the adoption of electric transportation. For years, the biggest hurdles in the EV world haven't been about if we switch to electric, but how. Range anxiety, high vehicle cost (often tied to battery size), and the overall weight of these batteries have been constant challenges. Proterra, a company spun out from a successful electric bus manufacturer, understands these challenges intimately. They've been solving them for years in the demanding application of heavy-duty, commercial vehicles. Now, that expertise is being brought to bear on passenger EVs and a wider range of applications. What Makes “Large Featherlight” Different? Let's be honest, "featherlight" sounds like marketing hype. But in the world of EV batteries, it’s a surprisingly accurate descriptor. The core innovation behind “Large Featherlight” isn’t a single breakthrough, but a carefully orchestrated combination of advancements in cell chemistry, module design, and pack architecture. “We weren’t aiming for a small improvement, we were aiming for a leap,” explains Greg Hayes, Chief Technology Officer at Proterra Power. “We looked at every single component, every connection, every piece of material, and asked ourselves, ‘Can we make this lighter, more efficient, and still maintain the rigorous safety standards we demand?’” The results speak for themselves. The “Large Featherlight” pack boasts a significant increase in energy density – packing more kilowatt-hours (kWh) into a smaller, lighter package. While Proterra isn’t releasing exact kWh/kg figures just yet (citing competitive reasons), they confirm that the “Large Featherlight” pack offers approximately 25% higher energy density compared to their previous generation packs, and outperforms many comparable packs currently on the market. Digging Deeper: The Key Technologies So, how did Proterra achieve this impressive feat? Here’s a breakdown of the core technologies driving the “Large Featherlight” pack: Advanced Cell Chemistry: Proterra is utilizing a next-generation Nickel-Cobalt-Manganese (NCM) cell chemistry optimized for both energy density and cycle life. This isn't just about what the cells are made of, but how they're made. Proterra works closely with leading cell suppliers to ensure consistently high quality and performance. Cell-to-Pack Design: Traditional battery pack designs rely heavily on modules – groupings of cells connected together. This adds weight and complexity. “Large Featherlight” utilizes a more direct cell-to-pack architecture, minimizing the need for intermediary modules and reducing overall weight. This also improves thermal management, allowing the pack to operate more efficiently. Lightweight Materials: Proterra isn't just focusing on the cells themselves. They’ve meticulously optimized the entire pack structure using advanced lightweight materials – including carbon fiber composites and high-strength aluminum alloys – without compromising structural integrity or safety. Integrated Thermal Management: Keeping the battery pack at the optimal temperature is crucial for both performance and longevity. “Large Featherlight” features an advanced liquid cooling system that distributes heat evenly throughout the pack, preventing hotspots and maximizing energy efficiency. What Does This Mean for EV Manufacturers and Consumers? The implications of “Large Featherlight” are far-reaching. Extended Range: EV manufacturers can equip their vehicles with larger battery packs, extending range without adding excessive weight or cost. This addresses a major concern for potential EV buyers and makes electric vehicles more practical for long-distance travel. Reduced Vehicle Weight: A lighter battery pack translates to a lighter overall vehicle weight, improving acceleration, handling, and energy efficiency. Lower Vehicle Cost: While advanced technology often comes with a premium price tag, the increased energy density of “Large Featherlight” can actually reduce the overall cost of the battery pack, making EVs more affordable. Fewer cells needed for the same range = cost savings. Faster Charging: The improved thermal management system allows for faster charging rates, reducing downtime and making EV ownership more convenient. Versatility: Beyond passenger vehicles, Proterra anticipates “Large Featherlight” being implemented in a wide range of applications, including delivery vans, trucks, buses, and even stationary energy storage systems. Proterra: From Buses to the Future of EV Power Proterra’s journey began with a focus on electric buses, where the demands on battery technology are particularly stringent. These vehicles require high capacity, long life, and exceptional reliability. This experience has provided Proterra with a unique understanding of battery performance in real-world conditions. “We learned a lot building batteries for buses,” says Hayes. “These are tough applications. It forced us to push the boundaries of what’s possible. Now, we’re taking that expertise and applying it to a wider range of vehicles.” Availability and Next Steps Proterra is currently accepting orders for the “Large Featherlight” battery pack. The company anticipates initial deliveries to OEM partners in Q2 2024. Proterra is also working on scaling up production to meet anticipated demand. “We’re confident that ‘Large Featherlight’ will play a significant role in accelerating the adoption of electric vehicles,” concludes Hayes. “This isn’t just about building a better battery; it’s about building a more sustainable future.” About Proterra Powered LLC: Proterra Powered LLC, based in Burlingame, California (1815 Rollins Rd, 94010-2204, 254-542-8622), designs and manufactures industry-leading battery packs for electric vehicles. With a proven track record of innovation and a commitment to sustainability, Proterra is empowering the next generation of electric transportation.
