Budget robot rail power and complete missions, verify actual pack and power-path limits, then retain measured energy and equipment configuration.
List mission states, duration, payload, terrain and required behavior at low battery. Record source voltage range, motor/control rails and the longest required task. Define the reserve policy separately from the usable energy measurement.
Record each subsystem’s actual rail voltage and continuous/peak current with the applicable conversion efficiency. Obtain motor winding-current events from documented or controlled measured cases. Mechanical torque and shaft power inform load requirements but do not directly determine battery or stall current.
Use measured or documented usable pack watt-hours at relevant load, temperature and cutoff. Enter battery-side state power and apply any additional reserve once. Compare the target complete mission count and record whether nominal voltage times amp-hours is only an approximation.
Check pack/BMS, connectors, wires, converters and driver limits for the actual voltage and simultaneous events. Review low-voltage response, fusing, mounting, charger compatibility and regeneration under the exact equipment instructions. Do not assume that parallel packs are compatible or safer.
Run a supervised mission under a defined load and environment with appropriate stop criteria. Measure battery voltage, current, energy and temperature; observe reset, fault and low-battery behavior. Compare predicted and measured state durations and usable energy without intentionally exceeding pack limits.
Export the mission budget, selected hardware, charger settings and measured validation results. Track discharge throughput on a fixed capacity basis and keep inspection or fault observations separately. Repeat validation after changes to payload, gearing, firmware, battery or charging configuration.
Build a complete mission-state schedule and energy target. · Calculate mission energy and whole missions from usable pack energy. · Update the mission with measured battery-side power. · Save comparable mission cases and their conditions.
Sum actual multirail continuous and simultaneous peak battery power. · Revise measured rail and peak-current cases.
Check the mechanical load and gearing basis separately.
Compare actual winding-current events with driver conditions. · Retain the driver voltage, current and compatibility result.
Record the charge window separately from measured usable watt-hours. · Log measured discharge throughput without claiming remaining cycle life.
Compare actual DC rails and combined pulse demand.
Check documented wire/connector current and DC loop drop.
Loading your checklist…
Actual current basis and thermal/event conditions matter for motor power-path decisions.
Use a complete source-side energy budget and keep losses on the correct side of the converter.
Use the exact pack, protection and charger instructions for operation, care and retirement.
A short event can limit the hardware even when its contribution to mission energy is small.
Additional mass or a different surface can change both motor peaks and energy consumption.
