How much battery is really left?
Capacity, fade per year and remaining life, learned from your own discharges in orbit. No bench test, no datasheet guess. And the end of life your own mission sets: the capacity it needs to cross its longest eclipse. Then the years a change of operations buys, with its range.
A PDF report you can forward, with the file and its fingerprint on the page.
How it is measured
- The pack is learned in flight: capacity from your discharges, resistance from every current step, each with a calibrated range.
- Pass telemetry is enough: a few samples per pass, placed on the orbit, give the health trend of the whole fleet.
- Each panel against the others, and the power electronics: rails, converters, reboot and latch-up counters.
- Every warning with its physical reason: charging in shadow, a drop the model cannot explain, a charge that never completes.
