Add the costs that occur before and after the invoice unit price: sample and qualification work, inspection, branding, freight, customs, receiving, installation, training, spare inventory and support handling. Use your own quotes and labor rates. Keep uncertain values visible as open assumptions so the comparison shows which supplier scope still needs confirmation.
Who needs this guide?
This guide is for importers, distributors and fleet procurement managers. It supports an operational or purchasing decision; it does not replace the battery manufacturer’s instructions, the exact charger documentation or a qualified integration and electrical review. Record nominal voltage, capacity in Ah, chemistry, permitted charge current and voltage limits, BMS requirements and the approved connector. Voltage alone never establishes compatibility. Name the person responsible for closing each missing field and keep the source date with the answer. When the decision covers several vehicles, start with the exact configuration group reviewed. Update requirements and evidence together when a supplier, battery, site or order changes, so an old email, photograph or quotation does not become the accidental approval record. Record the final decision, approver and effective date where operators and purchasing staff can find them. Keep observations separate from conclusions. A visible label, a familiar plug or a charger that starts once can support an enquiry, but each still needs the relevant document and approved operating context. This makes the article useful to the next person handling the same asset months later.
Which facts should the team put side by side?
| Decision field | What to record | Why it matters |
|---|---|---|
| Qualification | Samples, technical review and approved testing | Occurs before production release |
| Order preparation | Artwork, documents and inspection scope | Varies by project |
| Logistics | Freight, customs, local handling and damage process | Varies by destination |
| Deployment | Installation, assignment and operator handover | Occurs after receipt |
| Operation | Spare stock, downtime and support administration | Affects ongoing cost |
Write unknown when a field is missing. A blank or a familiar product name should not silently become an approved value. Keep the date and source beside information that may change.
How should the team work through the decision?
- 1. Choose a common quantity and time basis.
- 2. Enter only supported supplier and internal costs.
- 3. Separate one-time from per-unit and recurring items.
- 4. Flag missing costs rather than entering zero.
- 5. Run scenarios only with labeled assumptions and update them after real orders.
Give each open point an owner and review date. When a requirement changes, revise the requirement and its evidence together; otherwise an earlier quotation or photograph can quietly remain in circulation.
What common mistake causes avoidable problems?
Do not publish a savings percentage without actual comparable data. A low unit price may be valid; the framework simply ensures that different scopes are not mistaken for the same total cost.
Keep electrical work with qualified personnel. Do not open a charger, probe exposed contacts, repin a connector, bypass a BMS or interlock, or reconnect damaged equipment to reproduce a problem. Follow the exact equipment instructions and local site rules throughout the review.
If equipment has damaged cables, scorching, unusual smell, leakage or another abnormal condition, follow its stop-use and safe-isolation instructions and obtain qualified support. The purpose of the record is to improve the decision, not to encourage repeated connection of uncertain equipment.
What evidence should be kept?
Keep supplier quotes, freight offers, internal labor assumptions and dates beside the calculation. Confirm currency, tax treatment and trade terms with the responsible parties.
Name the specific assets and revisions covered by the evidence. A document stored without that link can be mistaken for approval of a different order or vehicle.
How does this affect a new charger enquiry?
For a new or replacement industrial battery charger, send the confirmed battery and operating information with the enquiry. Ask the supplier to identify the exact proposed configuration and mark unsupported or open requirements. Read the related guide on fleet spare charger planning for the closest existing decision.
For industrial-line orders, the confirmed MOQ is 30 units. Branding labels are available from 200 units after artwork confirmation; mixed-model thresholds require confirmation. Production is approximately 15-30 days depending on quantity and customization. Shipping and customs time are separate. Ask the quotation to state the exact model mix, scope and timing basis clearly in writing for the buyer’s final internal review and approval.
These commercial terms apply to the industrial line and do not establish stock, single-unit replacement, warranty, mixed-model eligibility or custom packaging. Confirm those items in the quotation for the specific order.
Questions buyers ask
Does MOQ belong in total cost?
Yes. The purchase quantity and usable mix affect cash and inventory, while mixed-model eligibility must be confirmed.
Can warranty value be estimated as zero when terms are missing?
No. Mark the term and related cost as unconfirmed rather than creating a favorable assumption.
