Charging Station Count Capacity Calculator at 69% charging station uptime: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop charging station uptime to 69%, then walk the calculation through step by step. Estimate charging station supported capacity from robots charged per cycle, charge cycles, charger uptime, and successful charge rate.

The inputs for this scenario

  • Robots charged per charger cycle: 6 robots/cycle (held at the documented default)
  • Charger cycles available per day: 30 cycles/day (held at the documented default)
  • Charging station uptime: 69 % (the input this scenario stresses; the baseline uses 96)
  • Successful charge completion rate: 95 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross charging station capacity = robots served per charger cycle × available charger cycles.
  • Successful robot charge capacity works out to 118 charge events/day at these inputs, and this is the headline figure for the scenario.
  • Gross charging station capacity works out to 180 charge events/day at these inputs.
  • Charge events lost to charger downtime works out to 55.8 charge events/day at these inputs.
  • Charge events lost to charge exceptions works out to 6.21 charge events/day at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where charging station uptime sits at 96% and the headline result is 164 charge events/day, this scenario comes in 28.13% below the baseline at 118 charge events/day.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to charging station uptime, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes charge demand is spreadable across all available cycles; it does not model demand peaks where many robots need charge simultaneously, which can starve a fleet even when daily capacity looks sufficient.

Results at a glance

  • Successful robot charge capacity: 118 charge events/day (headline result)
  • Gross charging station capacity: 180 charge events/day
  • Charge events lost to charger downtime: 55.8 charge events/day
  • Charge events lost to charge exceptions: 6.21 charge events/day
