Element Energy – Battery Management Reimagined

Element’s Battery Management System (BMS)

Proprietary hardware, software, and controls to reimagine batteries.

Decarbonizing requires
a lot more batteries

By 2030

Capacity

The grid is at the beginning of a multi-trillion-dollar transformation to achieve carbon neutrality and improve reliability and resiliency – this requires a near-complete overhaul, from a model of “generate-consume” to one of “generate-store-consume”.

We Make Battery Packs
Safer, Longer Lasting & Higher Output

Conventional battery management systems that treat all battery cells as forever identical have been unchanged for 30 years. Rare manufacturing defects present in one in a million cells have led to hundreds of battery fires, creating more than $4B of recalls in electric vehicles.

Battery Management Re-Imagined,
Adaptive BMS Architecture

Element has re-architected the battery pack from the ground up with new hardware, software and controls that fundamentally improves the way batteries are managed – our system is distributed, adaptive and intelligent.

The Future of Battery Management

SAFER

Finds & mitigates failures in advance of thermal runaway

Each battery cell is continuously monitored for outlier behavior and suspicious cells can be deeply diagnosed in the field without impacting the output of the pack. Safety and performance concerns of individual cells are mitigated through adaptive charging routines and weak or failed cells are isolated while the pack continues to operate. Fault response is up to 100x faster than conventional BMS, providing a quicker and safer resolution to prevent cascading failures.

LONGER LASTING

Up to 50% increased battery lifetime

Our cell management algorithms iteratively monitor, model and manage the operation of each cell in the pack independently, reducing wear and extending the life of each cell and the entire pack. The fastest-aging cell no longer limits lifetime and rollover fade in deeply cycled packs is avoided to a much lower state-of-health.

HIGHER OUTPUT

Up to 50% higher energy throughput over life

Battery packs with conventional BMS are limited by the weakest cell. Element’s BMS is able to fully utilizes each cell’s available capacity, eliminating stranded energy. This advantage grows with time as the cells in conventional BMS packs age differentially.
