Work out charging dock cycle time instantly with clear inputs, formula shown and shareable results.
Charge time is amp-hours to replace divided by charge current, then divided by charge efficiency. The result drives fleet sizing directly: if a robot needs 20% of its cycle on the charger, the fleet must be 20% larger than the mission count suggests — or opportunity charging must be scheduled.
Charge time
Ah replaced = capacity x depth discharged; time = Ah / charge current / efficiency
Constant-current charging ends around 80% state of charge, after which constant-voltage tapering can take as long again for the final 20%.
Short top-ups during natural idle time, keeping the pack in a mid state of charge. It maximises availability and is gentler on lithium chemistry.
