Estimate usable agricultural robot runtime from battery energy, average traction and implement load, auxiliary power, reserve state of charge, and system efficiency. The calculator also estimates full work cycles and daily charging energy for planning field shifts and charging infrastructure.
Runtime = battery kWh × (1 − reserve) × efficiency ÷ (average work load + auxiliary load).
The main result is a planning estimate based on the entered operating assumptions. Supporting metrics show the intermediate capacity, cost, energy, or utilization effects that drive it.
This tool is an operational estimate, not a manufacturer guarantee. Confirm safety limits, local rules, equipment specifications, and site conditions before deployment.
A 24 kWh battery with a 15% reserve and 92% efficiency supplies 18.77 kWh. At a 5.4 kW total load, estimated runtime is about 3.48 hours.
It uses only the values entered above and the formula shown on this page. The estimate does not automatically account for site-specific constraints that are not entered.
Use measured logs from comparable shifts or missions when possible. If records are unavailable, test conservative and optimistic scenarios instead of relying on a single guess.
Weather, downtime, route geometry, operator procedures, equipment condition, payload, and unplanned interruptions can change actual performance.
Yes where the field allows zero. Required time, capacity, rate, or workload inputs must remain greater than zero so the calculation stays meaningful.
Keep the displayed estimate for comparison, but round fleet requirements up to whole machines and add operational contingency where missed deadlines carry a cost.

| Battery capacity | Nameplate stored energy |
| Reserve | Energy intentionally left unused |
| Average load | Time-weighted traction, implement, and auxiliary power |
