Name the intervention without exaggerating its scope
Ask whether the record concerns diagnosis, external equipment, cooling, removal, internal work or complete replacement. Keep the provider’s original description beside any translation. The battery and charging review addresses current evidence; it cannot reconstruct an undocumented work history from dashboard range. Do not rewrite every intervention as a rebuilt or factory-new pack. Retain seller statements, attributable records and unresolved claims separately. A battery disclosure does not prove a universal Tai 7 defect, while absent disclosure does not certify another candidate’s untouched history. The buying question is whether the particular installed configuration and present findings can support acceptance within a useful accountable scope.
Match the installed system to the correct propulsion record
Collect VIN, production identity and applicable component identifiers through qualified review. Use the PHEV versus EV parts-matching guide instead of borrowing battery or charging descriptions across products. Ask which work records identify the actual parts, provider, date and stated reason for the intervention. A receipt supports the described transaction, not automatically compatibility, workmanship, newness or export coverage. Preserve gaps until the responsible source can clarify them. If software or cooling equipment changed as part of the recorded work, retain applicable details without assuming a new label makes every system compatible. The current installed configuration is the one the receiving provider must be able to support.
Arrange qualified current assessment within safe limits
Agree a suitable high-voltage examination with a qualified provider for the offered propulsion and intervention. Retain available diagnostics, accessible enclosure observations and appropriate charging or controlled-drive results with their conditions. The charge inlet and lock review addresses relevant physical concerns without authorising live-contact handling. Do not open a pack or improvise a charging test to pursue a health number. Record unexamined areas and questions needing further diagnosis. State of charge, a warning-free display or one successful session cannot certify every earlier operation or remaining life. A useful report describes what was examined and which conclusion its findings support, including consequential uncertainty rather than an unexplained pass label.
Confirm practical support where the owner will use it
Ask actual destination providers about diagnosis, applicable component identification and the relevant work they can undertake. The maintenance and parts plan separates ordinary service from high-voltage support. Keep location, equipment access, commercial exclusions and uncertain lead times visible. Do not assume a workshop supporting another related EV covers the installed PHEV or a later charging version. Any manufacturer or seller coverage needs applicable written terms for this vehicle, intervention and receiving market. A repaired candidate with apparently satisfactory current operation can still be poor purchase value when consequential support is unavailable to this owner. A domestic warranty description cannot by itself resolve that export-support question.
Price understood consequences against an accepted alternative
Compare actual offers with equivalent essential suitability, current examination and delivery boundaries. Use the negotiation review to distinguish defined correction from an unresolved consequential issue. Obtain attributable quotations where work is understood and count included operations once. Do not invent a universal pack replacement cost or claim a large discount covers every possible battery outcome. An unexamined higher-priced alternative is not automatically a clean comparison. Where identity, compatibility or necessary diagnosis remains unresolved, keep acceptance conditional rather than converting missing evidence into a confident cost allowance. The prepared price can support a commercial choice only after the buyer understands which technical conditions are genuinely accepted.
Carry intervention evidence and limits into handover
Record installed identity, attributable work, accepted current findings, usable support and unresolved limits in the purchase equipment schedule. Attach the provider records and specify affected verification after further work or movement. The pre-shipment reinspection preserves the accepted configuration within its scope; it does not guarantee unlimited battery life. A changed VIN, additional intervention or incompatible identifier reopens the affected decision. Choose acceptance, further qualified assessment or another vehicle according to consequential findings and usable evidence. Do not describe all intervened systems as unsafe, renewed or equivalent to untouched hardware; each such claim requires facts that the current purchasing file may not establish.
DECISION CONDITIONS

BUYER FILE
Evidence to retain
- Define the actual intervention type.
- Match records to the exact PHEV or EV.
- Use qualified high-voltage assessment.
- Confirm practical receiving support and coverage scope.
- Preserve intervention limits and recheck requirements.
QUESTIONS
Close the relevant uncertainty
Does battery work automatically disqualify a Tai 7?
No. Scope, installed identity, current findings and usable support determine the particular acceptance decision.
Can one charging session establish remaining battery life?
No. It is a limited observation under stated conditions, not a lifetime or workmanship guarantee.
