  HiTHIUM (Xiamen Hithium Energy Storage Technology Co., Ltd.) is a Chinese energy storage
  company founded in 2019 that designs and manufactures lithium iron phosphate (LFP) cells,
  modules and complete battery energy storage systems (BESS) for utility-scale, commercial and
  industrial, and residential applications. The product line runs from large-format prismatic
  ESS cells through liquid-cooled multi-megawatt-hour container systems to the HeroEE
  residential and portable range marketed at hero-ee.com. Company material reports roughly
  8,000 staff, more than 1,100 R&D engineers and over 3,900 patents. Product pages publish
  named certifications including UL 1973, UL 9540, UL 9540A, NFPA 855, IEC 62619, IEC 62477,
  IEC 63056, IEC 61000 and UN 38.3. HiTHIUM operates a Product Security Incident Response Team
  (PSIRT) running an IEC 62443-aligned vulnerability management process, and publishes numbered
  cybersecurity bulletins with CVE references and remediation guidance at
  hithium.com/support/security.html. HiTHIUM publishes no developer portal, no API reference,
  no OpenAPI, AsyncAPI, GraphQL or Postman contract, no SDKs, no CLI, no webhook catalog and no
  MCP or A2A agent surface; third-party integration happens over Modbus/CAN interfaces
  described in datasheets and manuals that sit behind the download-center account gate, and the
  HeroEE consumer app's backend is undocumented.

  Enriched 2026-08-22 with full STEP 0b contract discovery. www.hithium.com and en.hithium.com
  404 on /openapi.json, /swagger.json, /llms.txt and every /.well-known/* path; api., developer.,
  dev., docs., cloud., open., openapi., iot., ems., portal. and app..hithium.com do not resolve;
  hero-ee.com is a Next.js locale catch-all that answers 200 with the same 504KB HTML shell for
  /openapi.json and /llms.txt (soft-200, not a document); there is no GitHub organization and the
  github.com/hithium user account holds zero repositories. The only machine-adjacent surface found
  is the site's own internal CMS AJAX (www.hithium.com/ajax/seculist), which is not a published API.

    HiTHIUM sells battery cells and containerised storage systems, not software: there is no
    developer surface anywhere on its estate - eleven candidate API/docs subdomains of hithium.com
    fail to resolve, every /.well-known/* path 404s on all three live hosts, the HeroEE brand site
    answers 200 with the same Next.js HTML shell for /openapi.json and /llms.txt (a soft-200, not a
    document), there is no GitHub organisation, and the only integration documentation that exists
    - the Modbus/CAN datasheets and manuals - sits behind the download centre's
    "Please login to download this datasheet" account gate.
