Identify what the quoted mass already includes
A battery may already be included in the supplier’s curb or completed mass. Check the definition before adding or subtracting it. Mixing chassis-stage figures with a finished-body figure can count an item twice or omit it entirely.
Use one schedule for the exact battery, body, crew and equipment. Gross mass minus ready-for-work mass gives an initial cargo allowance, but the cargo position and each axle can impose a tighter limit.
Review the completed vehicle and its load positions
A refrigerated body, van and dropside can distribute mass differently on the same electric chassis. Tie the calculation and weighing record to the offered configuration; another battery or body variant is not a reliable substitute.

| Decision | What to establish | Condition or limit |
|---|---|---|
| Configuration identity | Tie every mass figure to the exact battery, wheelbase, cab and body. | A figure from another variant is not the selected vehicle mass. |
| Completed tare | Include every installed system and operating item once. | Do not double-count or omit battery and body masses. |
| Gross payload margin | Subtract controlled completed mass from the approved gross limit. | The result is not final payload until axle and dimensional checks pass. |
| Axle loading | Calculate cargo and equipment reactions at credible positions. | Total mass compliance cannot cure an overloaded axle. |
Request a reconciled mass schedule and axle review
List included and excluded equipment, the weighing condition and representative cargo positions. Resolve differences between documents before stating the usable load to dispatch staff.
Information to prepare for this review
- Exact vehicle and battery configuration
- Gross vehicle and individual axle ratings
- Controlled chassis or completed curb mass
- Body, equipment, crew, tools and options
- Cargo mass and center positions
- Destination payload and dimensional rules
Records to request and keep
- Exact vehicle and battery identity
- Controlled completed-mass or weigh record
- Body and equipment mass schedule
- Loaded gross and axle-reaction calculation
Common mistakes and what to check instead
- Using a bare-chassis payload figure: Use completed body, equipment, battery and operating mass.
- Assuming battery mass always reduces payload one-for-one: Use the approved ratings and exact completed vehicle calculation.
- Checking only total payload: Verify every axle and cargo position.
Scope of this guide
This checklist does not establish a legal payload or approve body integration.
The exact OEM documents, completed weighing and destination rules control the result.
Reject or pause acceptance if configuration identity, completed mass, axle reactions or legal limits cannot be reconciled.
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.
