Plan one complete shift before selecting the battery
Build the vehicle brief from routes the fleet actually runs. Record distance, loads, stops, seasonal conditions and the hours that body equipment operates. A delivery truck can consume energy while stationary, so driving distance alone leaves part of the shift unaccounted for.
The charging window belongs in the same schedule. A truck that completes its route still needs to recover enough energy before the next departure. Include depot power, charger access, support and a practical response to a missed charge.
Compare vehicle capability with depot capability
DOE fleet guidance connects route planning with charging infrastructure. Its examples help organize the assessment; they do not supply a range rating for the proposed KEEYAK configuration. Use the completed body and a stated usable-energy basis throughout the comparison.

| Decision | What to establish | Condition or limit |
|---|---|---|
| Duty cycle | Use measured routes, loads, auxiliaries and credible seasonal cases. | Published range from another test cycle is not a fleet-route promise. |
| Energy reserve | Define usable energy and an explained operational reserve. | Battery nameplate energy is not all available for every condition. |
| Vehicle capacity | Check body, payload, gross mass and each axle with the installed battery. | Electric drive does not remove legal load limits. |
| Charging system | Match vehicle, charger, power, dwell and operating schedule. | Connector fit alone does not prove charging time or interoperability. |
Request a route-based proposal and trial plan
Send the shift schedule, cargo and auxiliary loads with the depot information. Ask the supplier to identify assumptions, reserve and validation conditions. Record who owns vehicle faults, charging faults and recovery arrangements before expanding the fleet.
Information to prepare for this review
- Measured route distance, speed, stops and grades
- Payload, body and auxiliary power demand
- Climate and seasonal operating conditions
- Shift timing, dwell and backup vehicle plan
- Depot electrical capacity and charging interface
- Destination approval, warranty and service support
Records to request and keep
- Measured duty-cycle and payload dataset
- Vehicle energy, range and auxiliary-load basis
- Completed-vehicle mass and axle calculation
- Depot charging and service-readiness plan
Common mistakes and what to check instead
- Selecting from brochure range: Model and pilot the actual route, load, climate and auxiliaries.
- Planning chargers after vehicle purchase: Confirm site power, interface, dwell and commissioning before order.
- Ignoring body auxiliary loads: Include refrigeration, pumps, heating, lighting and other real energy demand.
Scope of this guide
This guide does not guarantee range, battery life, charging cost or regulatory eligibility.
The selected OEM data, site engineer and destination authority remain controlling.
Pause procurement when route evidence, charging capacity, payload, service support, safety approval or recovery plan is unresolved.
Sources and applicability
Controls the project-input, quotation, approval and inspection workflow described in this guide.
Provides public checklists and worksheets; the signed project documents remain controlling.
Defines the relevant product family and published configuration boundaries. Project-specific ratings require the selected OEM documents.
Primary public guidance supporting route, dwell-time, charging-plan, procurement and infrastructure inputs. U.S. programs and examples are not global requirements.
Primary international regulation reference for electric-powertrain and rechargeable-energy-storage safety where adopted. Applicability and approval status must be confirmed for the vehicle and destination.
