The biggest blocker
The biggest roadblock to used NEVs is residual value. In Jun 2026 the State Administration for Market Regulation (SAMR) and MIIT released the 'Comprehensive Assessment Specification for Used Electric Vehicles', effective 1 Sep—the first national-grade standard for used EVs. Buyers once feared 'unclear battery fade, watery price'; now there is one ruler: the spec puts battery SOH, accident history and cycle count into mandatory assessment, moving used-EV trade from 'by feel' to 'by data'.
Three forced disclosures
The hardest clauses are 'three forced disclosures'. One, battery SOH test error within ±3%, giving a comparable objective value. Two, accident and major-repair history must be stated, especially for traction-battery/drive repairs. Three, charge-discharge cycles and max chargeable capacity recorded truthfully. From this the industry grades: SOH>85% excellent, 75–85% acceptable, below 75% 'impaired'. Estimates: each 1% SOH drop cuts mainstream-model residual ~1.2–1.6%, premium ~2%—battery state directly decides the money in your pocket.
Yantai's health ledger
For Yantai owners this standard is concrete. Dongdian Huichong's community and public charging long reminds owners to 'use good power, keep a good battery': charge at compliant stalls, avoid long full-charge/full-discharge, watch SOH regularly—extending life and keeping a 'health ledger' for resale. With a national standard backing used-EV grading, buyers dare buy and sellers dare sell, and the used-EV cycle truly turns—turning 'car-and-battery' residual anxiety into a quantifiable, transparent trade.
