Battery intelligence
Every battery gets an agent.
Bekk tells you how much charge and life is left in each battery, how sure it is, and what to do next. Native on our packs; alongside any BMS over CAN.
The problem
Batteries guess their state, and age alone.
Readings drift
A typical BMS can misread charge by 10–15% in the cold and late in a battery's life.
Heat ages quietly
Calendar ageing roughly doubles for every 10 °C hotter, and no BMS tells you what a summer cost.
Numbers without confidence
Charge and health arrive as single numbers that nobody can bank on.
Figures from published BMS and cell-ageing literature.
What Bekk does
A battery that knows what it doesn't know.
Two numbers, not one
Stored charge, and the energy you can actually use now. Each comes with a band that holds the true value nine times in ten.
Uncertainty you can act on
A narrow band releases the pack. A wide one says top it up or rest it first.
Faults caught early
Safety alerts fire on the pack in under a second. Slow drift is checked against each cell's own birth record.
Every cell has a birth record.
Every pack has an agent.
Built inside a working battery factory, so every estimate starts from how the cell was made.
How it works
On the pack. In the cloud. Across the fleet.
On the pack
Edge agent
Native on our BMS. On other packs it runs on the telematics unit, beside any BMS, over CAN.
In the cloud
Digital twin
A physics model of each battery, sharpened by its factory grading data.
Across the fleet
Agent network
Batteries share what they learn. An open API for OEMs, operators and financiers.
Safety first: learned models may only derate. Hardware protection is never overridden, and if the cloud drops, the pack falls back to a fixed, verified profile.
Who it's for
Built for the people who run, store and finance batteries.
Fleets and swapping
Service before failure. Swap release set by the band, not a timer.
Energy storage
Dispatch that knows its wear cost. Even ageing across racks.
Lenders and insurers
Signed health certificates. Residual value based on evidence.
Our approach
How we stay honest.
Shadow mode first
Bekk runs quietly beside the existing BMS before anyone acts on a number.
Checked against measurement
Estimates are tested against controlled reference discharges on held-out packs.
Calibration in the open
We publish calibration audits with sample sizes and confidence intervals, every quarter.
