Providing flexible, dispatchable, high-efficiency power
Truck manufacturers striving to complete the diesel-to-electric transition want battery packs that are inexpensive, energy-dense, chemistry-agnostic, and domestically sourced. That’s the combination Estes Energy Solutions offers, with breakthrough multi-chemistry (sodium, LFP, and nickel) battery packs that use novel materials, advanced manufacturing techniques, and architectural optimizations to deliver the densities and voltages needed for heavy-use applications. The company aims to reshore the battery value chain by providing standardized powertrain solutions that outstrip diesel in cost and performance.
