Standards, protocols, and conformance position

ChargeLink does not treat all protocols as one undifferentiated standards claim. The snapshot separates standards families, conformance-style packages, interoperability packages, HIL packages, and evidence add-ons.

Supported protocol families in the snapshot

Family

Current snapshot position

What remains open

ISO 15118-2 AC

Preserved AC EIM baseline; packaged conformance and interoperability coverage; protocol gate green.

Broader vendor proof and launch hardening.

ISO 15118-2 DC

EIM and PnC baselines, realistic electrical behavior, TLS, EXI, identity binding, MeteringReceipt surfaces, packaged coverage, protocol gate green.

Natural cross-vendor MeteringReceipt, EMAID cleanup, broader vendor proof.

DIN 70121 DC

Repeated live proof through SessionStop, negative matrix, conformance/interoperability packs, protocol gate green.

Close vendor-adapter gates and broaden partner or hardware proof.

ISO 15118-20 AC

Live realistic EIM flows through SessionStop over TLS and native EXI, packaged interoperability and negative coverage, protocol gate green.

Broader vendor proof and future formal AC conformance.

ISO 15118-20 DC

Live PnC/BPT baseline through SessionStop over native EXI and TLS, MeteringConfirmation qualification coverage, packaged conformance/interoperability families.

Broader vendor proof and deeper certificate scope.

MCS

Live EVSE MCS path on shared ISO 15118-20 runtime binding, hardware profiles, bench controller, conformance/interoperability partial packs, EVCC differential matrices.

Claim-safe semantics, repeated physical-bench proof, broader vendor evidence, and promotion from partial to full.

How to read the package catalog

  • CL-CONF-* packages are conformance-oriented families aligned to the relevant standard generation.

  • CL-INT-* packages are interoperability-oriented families that prove multi-vendor or multi-profile behavior.

  • CL-HIL-* packages are hardware or bench proof surfaces.

  • CL-EVIDENCE-PRO and CL-VENDOR-ADAPTERS add reporting or adapter capability on top of the shared runtime.

Important claim boundary

Warning

The snapshot makes a clear distinction between strong CCS protocol baselines and claim-safe production launch. MCS remains partially gated, and the commercial core still carries explicit cleanup requirements around first-party message models and EXI replacement.
