Battery Cell-Level Control Fundamentally Changes Stationary Battery Energy Storage: Unlocking Improved Capacity, Cost, and Safety While Enabling a First and Second-Life Batteries Circular Economy

Adopting cell-level control for stationary battery energy storage systems fundamentally changes how systems are designed, operated, and maintained, adding significant financial, safety, and performance improvements — all to further accelerate grid decarbonization.

This new approach delivers substantially longer battery life, greater throughout while achieving lower power electronics cost, along with improved safety due to the ability to bypass problematic cells. The technology is applicable to new and second-life lithium chemistries and alternative or emerging battery types. Cell-level controlled systems deliver grid-compliant AC directly from the battery pack and achieve full capacity utilization of every cell.
