Fast charge, without the downside.

ActiveBMS allows any li-ion battery to charge 6x faster than conventional technology and retain longer cycle life.

How does ActiveBMS work?

ActiveBMS is based on a simple concept: each li-ion battery cell is unique, and thus for the cell to perform optimally it needs it’s own distinct control procedure. The ancient, one-size-fits-all CC/CV approach is on its way out.

ActiveBMS is designed to stifle lithium-ion battery degradation mechanisms, such as growth of the SEI layer, anode cracking, and temperature growth by continuously adapting bursts of energy during the charging process. This unlocks new functionality within the battery, without altering how the battery is manufactured - only how it’s controlled inside of an electrical device.

Data and State of Technology

ActiveBMS technology has been validated inside of a lab environment, and has also been implemented into a consumer electronics product - BatteryBox - that serves as a commercial field-test of the technology. It's sold thousands of units, and has allowed us to improve ActiveBMS algorithms on a mass scale.

Cycles tracked by ActiveBMS

Better cycle life at 6x charge speed

An cycle life test between a subset of identical li-ion cells, where one subset was charged using a typical CC/CV protocol, and another using ActiveBMS.

All test parameters were monitored and controlled (ie. sample subsets, charge/discharge cutoffs, temperature environment, charge/discharge C rates).

Minimal temperature increase

Comparison between a subset of identical li-ion cells charged to 100% at a high rate, where one subset was charged using a typical CC/CV protocol, and another using ActiveBMS.

Use Cases and Implementation

ActiveBMS can be implemented into any existing battery-powered system, without making any changes to the battery chemistry or manufacturing process. It works with existing li-ion battery cells’ by integrating with the existing battery management system (BMS) circuit through a software solution.

Consumer Electronics

ActiveBMS enables near "zero down-time" wearables, and nearly tether-free smartphone usage.

Silicon Anode

ActiveBMS has been tested and proven to greatly increase the cycle life of Si anode based li-ion batteries at industry standard cycling test parameters.


ActiveBMS enables an EV to charge in nearly the same time it takes to fill up a tank of gasoline.
