OWN / FIELD NOTE 30
CONNECTED DECISIONS
Separate PHEV thermal behavior with the engine and hybrid inspection. For EV use, connect the result to the EV range and charging route. Price climate-system support in the destination maintenance plan.
Record shade or sun, ambient and cabin temperatures, soak duration, door and window state, passengers and battery or fuel state. A recently cooled showroom vehicle cannot be compared with one parked in direct sun.
Test fan speeds, vent selection, recirculation, temperature commands, demist and rear-cabin outlets. Note slow actuators, clicking, intermittent displays, odor, uneven airflow and drainage rather than judging only the driver vent.
Use safe conditions to compare stationary READY operation, traffic-speed use and a steady road segment. Record engine intervention on PHEV, energy demand on EV, warnings and any loss of performance under load.
Check accessible filters, intakes, condenser area, drains and leakage evidence. Preserve relevant faults before clearing. Refrigerant and high-voltage compressor work requires trained personnel and the correct procedure.
Comfortable cabin air does not prove engine, inverter or battery cooling health. Inspect the applicable fluids, fans, heat exchangers and operating data separately, then price version-specific diagnostics and parts at destination.
HANDOVER FILE
BUYER SCENARIO
Place the vehicle in a documented hot-soak condition, then test ordinary family cooling and a delayed-traffic case. Repeat after the road segment and inspect warnings, odors, condensate and powertrain temperatures. If cooling performance is acceptable only with an unrealistic starting condition, the ownership route remains open.
Stress the result by assuming “Observe low-speed and road behavior” reveals a conflict, “Inspect physical and diagnostic evidence” is delayed, or “Separate thermal systems and support” changes before custody. Rework the cost, timing and stop condition using road and idle climate observation, fault, filter, drain and condenser record, destination thermal-system support plan. A different VIN, propulsion route or installed configuration starts a new candidate record. The conclusion for Tai 7 Cabin Air Conditioning and Thermal Checks must explain how environment and cabin-temperature baseline and zone, vent and control-function map support or limit the selected route.
CLOSE THE FILE
For Tai 7 Cabin Air Conditioning and Thermal Checks, reconcile environment and cabin-temperature baseline, zone, vent and control-function map, road and idle climate observation, fault, filter, drain and condenser record, destination thermal-system support plan. Mark each item verified, seller-stated, estimated or unresolved, and put a responsible person and expiry date beside the open work. Keep commercial rows separate so a change in one assumption does not silently rewrite the whole conclusion.
Immediately before payment or handover, repeat “Create a repeatable cabin baseline” and confirm that the candidate still matches the reviewed record. Preserve the VIN, odometer, visible condition, keys, documents and relevant energy state. If the vehicle or a material specification changes, close this file and begin a new one.
OFFICIAL REFERENCE BOUNDARY
Fangchengbao may revise equipment, software and specifications. Match official information to the production record and actual installed hardware. Review the official Fangchengbao Tai 7 reference, then verify the candidate and destination independently.
BUYER QUESTIONS
No. Test every control zone and realistic operating condition.
No. Cabin and powertrain thermal paths need separate evidence.
No. Heat, solar load, passengers, settings, route and version all change energy use.
