First Global International Standard for Solid-State

Solid-state batteries crossed a key step: the first global standard is now at the IEC, initiated by China. For importers that means unified tests and safety reviews, fewer compliance unknowns and less duplicated verification.

Disclosed on 25 August, the proposal covers test items and application guidance for solid-state EV batteries, with French, Korean and Japanese experts. Its goal: end fragmentation, so one test result is accepted in many markets.

Industry is accelerating: CATL puts maturity at level 4 of 9, about 44 percent; BYD plans pilots around 2027 and volume after 2030; Gotion targets 20,000 tonnes of lithium sulfide in 2027 and 50,000 by 2030; SVOLT plans 400 Wh/kg by end-2027. Nodes cluster around 2027. Sulfide, oxide and polymer routes run in parallel — the winner is set by yield and cost, not lab specs, so prices during the ramp-up may swing widely; budget for that premium.

The standard will not change customs or certification rules overnight, as adoption takes time. The variable to track is timing: 2026-2027 will test volume and standards rollout. Plan intake in batches, not one big order, to spread the risk. Insurers and appraisers lack data on solid-state packs and will price conservatively; add a reserve line for residual value and after-sales in your quotes.

Act in three steps: add the IEC item to your watch list and get written supplier commitment; prioritise post-2027 models and put test details, connectors and warranty into contracts; brief sales teams against inflated claims.

What does solid-state battery mean for Chinese vehicle exports?
Solid-state batteries promise longer range, better safety and lower weight — a key variable for NEV exports. EZ Auto tracks production progress and overseas certification fit in the News section to help buyers time model upgrades.

What to watch with ADAS features for export?
Advanced driver assistance involves local regulation and data compliance. EZ Auto recommends only the assistance levels already approved in the destination and labels feature boundaries, avoiding over-promising.

Are Chinese NEV charging standards usable overseas?
Charging connectors and voltages differ by country (e.g. CCS2 in Europe, GB/T in China). EZ Auto recommends compatible models for your market or suggests in-car adapters.

Does over-the-air (OTA) update work overseas?
OTA depends on local networks and data compliance and is restricted in some markets. EZ Auto states OTA availability at delivery and points to offline maintenance and local service channels so features don't fall short.

Does the battery warranty remain valid after export?
Warranty usually follows the vehicle and the brand's global policy, but overseas service-network coverage varies. EZ Auto explains warranty scope and cross-border limits before closing the deal to avoid mismatched expectations.
