A low-voltage battery maintenance sheet should be able to explain what was measured. Writing only "charged" does not show why the charge was done, which equipment was used, or whether a recheck is needed afterward.
Thresholds Come from That Vehicle's Documentation
For a Deepal S05, first confirm the low-voltage battery type, the applicable test method and the maintenance requirements. Ford's public storage manual discusses the low-voltage battery and the traction battery separately; it is only an example of field design and its charge levels, intervals or disconnect methods must not be carried over to a candidate model.
| Check field | What to fill in | Who confirms |
|---|---|---|
| Test basis | Manual version, items and judgment conditions | Technical lead |
| Measured result | Instrument, reading and conditions such as vehicle rest | Person performing the check |
| Maintenance action | Equipment mode, process anomalies and final state | Qualified technician |
| Follow-up arrangement | Recheck conditions and unresolved issues | Inventory and technical roles |
The technical lead first states in the check task the documentation adopted and the applicable method; the person performing the check verifies the current battery identity and equipment state. Method conditions needing confirmation are written into the task sheet rather than copied from another vehicle's record. If a battery was replaced without the corresponding material, clarify the identity first, then decide the check arrangement.
When recording readings, keep the actual display and the vehicle state at the time; if the equipment cannot work properly or the conditions are not met, note the reason and hand the matter to the lead. The person compiling the sheet does not change blanks into "normal" and does not infer a health result from whether the vehicle started smoothly. Maintenance actions are confirmed by personnel with the corresponding capability.
A Successful Start Cannot Replace a Health Judgment
After the vehicle's power is restored, recheck it under the applicable procedure. HSE reminds us that electric and hybrid vehicles carry specific work risks; without confirmation, do not disconnect, jump-start or touch high-voltage systems on your own. When records are missing, do not backfill "normal."
Behind the check record, attach the reason for the action and the approval basis; the person performing the check writes the actual operating result, and the inventory role receives the next pending task. If an anomaly message appears or the plan cannot be completed, pause the original process and contact the technical lead for a judgment. Do not skip the scheduled recheck to rush a handover, and do not write that the battery passed simply because the equipment ran.
When different check results conflict, first compare the object, method and site conditions and have a professional explain the difference. If the cause cannot be determined, keep the item in a pending state. Original results already obtained remain on file; do not leave only the record that looks better for sales.
Follow-Up When the Maintenance Record Shows Only a Charge Mark
Example only; the contract and the physical vehicle prevail. The storage sheet for a given VIN notes only that charging was done, without the reason or the result. The inventory lead can look for the actual basis of the work with the person who performed it, register the missing items truthfully, and ask a technician to arrange an assessment of the current state. The new check states what was actually done and does not backfill it as previously completed.
When receiving the material, the handover staff can check whether the last valid conclusion, the unresolved issues and the person responsible for explaining them can all be found. If a later recheck is still needed, state the conditions it depends on and where the task belongs. For the customer, provide maintenance status that has been verified; do not present the process of completing the records as if the vehicle had never shown an anomaly.
FAQ
Do all stock vehicles use the same voltage threshold?
No single value applies; the battery type, method and manufacturer requirements must be matched.
If traction-battery charge is high, can the low-voltage battery check be skipped?
No. The low-voltage supply check cannot be omitted on that basis.
When the battery drains often, is charging it a few more times enough?
The cause should be found and the battery and the vehicle's power-supply system assessed.
How are maintenance records handed over before sale?
Provide the last check, the actions taken and the unresolved anomalies, not just the charging date.
To prepare a stock maintenance plan, provide the vehicle version, battery documentation and the testing equipment available through the Starvia contact page or WhatsApp.
