Risk guide

How much displayed range loss is abnormal?

Displayed range is not SOH, but it is one of the easiest onsite risk signals. Below 80% needs BMS review; below 70% should not be bought on a test drive alone.

Job: viewing decision For: pre-purchase review Verify with diagnostics

Problem this solves

Buyers see lower full-charge range but cannot tell whether it is seasonal variation, range-standard mismatch or battery risk.

Important boundary

This site only provides pre-purchase risk prompts. SOH, insulation, voltage delta, warranty and repair conclusions should be confirmed by manufacturer systems, professional reports, contracts and official explanations.

Onsite checks

Confirm whether the rated range is CLTC, WLTP/WLTC or NEDC

Record full-charge displayed range, temperature, drive mode and HVAC state

Compare with same-year listings in similar season and city

Read SOH, cell voltage delta, fault codes and mileage history

Red flags to treat seriously

Retention below 70%

Seller cannot explain the range standard

Abnormal short-trip range drop after full charge

Battery or high-voltage warnings in the cluster or app

Questions to ask

Ask the seller or inspector this way

Anchor questions to verifiable records, diagnostic items and written commitments to reduce information gaps.

Which range standard is this trim rated under?

What was the latest full-charge displayed range, with date and temperature?

Can we charge to a high state of charge onsite and recheck?

Can SOH and cell voltage delta be read before payment?
