AMR Battery Charge Capacity Calculator at 99% charger uptime: a worked example

This scenario runs the amr battery charge capacity calculator calculation on the strong side: 99% charger uptime, with every other input held at its documented default. an automation engineer needs to confirm whether charging capacity supports planned robot runtime

The inputs for this scenario

  • Robot runtime per charge cycle: 7.5 robot hr/cycle (unchanged)
  • Available charge cycles per day: 48 cycles/day (unchanged)
  • Charger uptime: 99 % (raised for this scenario; the documented default is 95)
  • Battery health or charge acceptance: 92 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross charged robot-hours = robot runtime per charge cycle × available charge cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 328 robot hr/day for usable charged robot-hours, the number this scenario is built around.
  • At this operating point the engine returns 360 robot hr/day for gross charged robot-hours.
  • At this operating point the engine returns 3.6 robot hr/day for robot-hours lost to charger downtime.
  • At this operating point the engine returns 28.51 robot hr/day for robot-hours lost to battery derate.

How this compares with the baseline

  • Against the tool's baseline example, where charger uptime sits at 95% and the headline result is 315 robot hr/day, this scenario comes in 4.21% above the baseline at 328 robot hr/day.
  • Use it when sizing charging infrastructure, validating a new AMR mission schedule, or diagnosing why a fleet runs short of energy before the shift ends. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Usable charged robot-hours: 328 robot hr/day (headline result)
  • Gross charged robot-hours: 360 robot hr/day
  • Robot-hours lost to charger downtime: 3.6 robot hr/day
  • Robot-hours lost to battery derate: 28.51 robot hr/day

Run it with your numbers

  • Every input above is editable in the live AMR Battery Charge Capacity Calculator calculator, which recalculates instantly and can be shared with the inputs intact.
