Conventional battery management was designed for a simpler era: monitor the pack, trust the average, and let the worst cell set the limits. The consequences compound at scale. The fastest-aging cell caps the lifetime of thousands of healthy ones. Stranded energy sits unusable inside every pack. And failures announce themselves too late — thermal runaway gives conventional systems minutes when the physics demand milliseconds. As batteries become infrastructure — grid storage, fleets, defense platforms — management technology built for laptops is being asked to safeguard gigawatt-hours.
Manage every cell. Waste nothing.
Element Energy rebuilt the battery management system from the cell up. Its architecture continuously monitors, models, and manages every cell in the pack independently: outlier behavior is diagnosed deep in the field without taking the pack offline, weak or failed cells are isolated while the system keeps operating, and fault response runs up to 100x faster than conventional BMS — stopping cascading failures before they start. The results compound over the asset’s life: up to 50% longer battery lifetime and up to 50% higher energy throughput, because no cell’s capacity is stranded behind the weakest link. The proof is operating today: the world’s largest second-life battery storage project, 53 MWh of retooled EV batteries — 900 packs — delivering grid power in West Texas.
More Thoughts From the Team at BVVC:
“Energy storage is becoming a strategic asset class — for the grid, for electrified fleets, and for the expeditionary power demands of modern defense. But the industry’s blind spot sits one layer below the headlines: everyone counts cells and chemistries, almost no one interrogates the management layer that decides how much of that storage is actually usable, for how long, and how safely. The BMS was an afterthought. At infrastructure scale, afterthoughts become liabilities.
Element attacks the constraint directly. Cell-level intelligence turns the pack from a chain — only as strong as its weakest link — into a system that adapts around weakness, extends its own life, and catches failure before it cascades. And because the same technology unlocks second-life batteries at scale, Element converts a looming waste stream of EV packs into deployable, domestic energy storage. That is not an efficiency gain. It is a circular supply chain the West does not currently have.
We invest in Teams, and this one has done the hardest thing in energy hardware: taken a fundamentally new architecture from theory to the largest operating deployment of its kind. The side that stores energy better fields more of everything. Element makes that side ours.”
“We’re thrilled that our technology completes the circular supply chain for energy storage, while also making batteries safer.”
