Declared by the test operator (profile v1); the test-case selection of this run was derived from this declaration, mirroring the ISO 15118-4 ATS control part ([V2G4-018]/[V2G4-019]). Test cases the declaration marks not applicable were deselected by default; any that were explicitly force-run are annotated “declared N/A (operator force-run)” at their result.

Verdict semantics: expected failures (author-flagged known deviations / non-deterministic cases) are reported as FAIL EXPECTED — genuine reds that are not hidden and must be explicitly accepted by the operator. A FAIL (or FAIL EXPECTED) accepted by the operator is reported as ACCEPTED FAIL with the mandatory justification and does not count against the overall verdict. Overall verdict is PASS only if no test case FAILs (or is left FAIL EXPECTED without acceptance) on any variant.

Operator-accepted deviations

Test case	Justification
TC_SECC_AC_VTB_CmSlacParm_003	Operator-accepted deviation from ISO 15118-3 [V2G3-M06-08]: after a positive EIM the dc100 SUT goes from X1 straight to nominal PWM without the E/F step for T_step_EF. Kept on purpose for compatibility with EVs without HLC that follow plain IEC 61851-1 charging and are confused by the extra E/F step.

TC_SECC_AC_VTB_CmSlacParm_003

TC_SECC_AC_VTB_CmSlacParm_003.

Test objective: Test System executes GoodCase procedure, indicates the initial CP State B waits for 100 % duty cycle and executes successful EIM process. Test System then checks that a nominal duty cycle can be detected after SUT changes CP State to E or F for T_step_EF. Furthermore a successful SLAC matching process shall be performed afterwards.

TC_SECC_AC_VTB_PLCLinkStatus_009

TC_SECC_AC_VTB_PLCLinkStatus_009.

Test objective: Test System executes GoodCase procedure, initiates an EIM authorization during the SLAC process, indicates the key at the local PLC node and then checks that the data link connection is established within 'TT_match_join'. Test System then checks if the SUT has changed from 100 % initial duty cycle to a nominal duty cycle during the matching process by detecting X1(100 %) to X2(nominal) transition after successful EIM process during the matching process.

TC_SECC_AC_VTB_PLCLinkStatus_011

TC_SECC_AC_VTB_PLCLinkStatus_011.

Test objective: Test System executes GoodCase procedure (100 % duty cycle), indicates the key at the local PLC node and then checks that the data link connection is established within 'TT_match_join'. Afterwards Test System initiates a connection loss by setting a new key at the local node. Test System then checks that the SUT performs a CP State X1 to E/F transition. Furthermore Test System checks that the SUT applies CP State E or F for T_step_EF and will switch to CP State X1 or X2 afterwards.

TC_SECC_CMN_VTB_SDP_007

TC_SECC_CMN_VTB_SDP_007.

Test objective: GoodCase (eIM / no-TLS); the Test System sends an SDP request with Security=0x00 (TLS requested) and TransportProtocol=0x00, and checks the SUT -- which offers only no-transport-security -- answers an SDP response announcing Security=0x10 (no TLS), TransportProtocol=0x00 and a valid port + IP. This is the transport-security-negotiation (mismatch) case that matters for the TCP-only SUT: a TLS-requesting EV must be told to fall back to plain TCP.
