Octillion Power Systems

What Octillion Power Systems does

Octillion Power Systems, founded in 2009 by Dr. Peng Zhou in Silicon Valley, is a vertically integrated designer and manufacturer of customized lithium-ion battery packs for electric vehicles, commercial vehicles, marine, off-highway equipment, and energy storage. Its product portfolio centers on three named pack families — Caspian (665V/99.8 kWh for buses), Mammoth (325V/36 kWh for trucks and commercial equipment), and Muriel (50V/1.7 kWh for high-performance applications) — supported by a proprietary Battery Management System (BMS) sold either standalone or integrated. The company's technology differentiation rests on two patented platforms: BEST (Bipolar Encapsulated Structure Technology), a liquid-cooled safety architecture designed to prevent thermal runaway propagation using thermal sensors, laser welding, encapsulation, and proprietary mitigation algorithms; and MUST (Multifunctional Unitized Structure Technology), a cell-to-pack structure that eliminates intermediate modules to deliver approximately 10% lower cost and over 40% higher space utilization than competitors.
