Proposal to amend para. 6.5. to specify that a verification of reported virtual distance is only required if the manufacturer requests to apply the virtual distance option, to require a test with adequate and representative vehicle use in V2X or non-traction purposes to verify accuracy of reported virtual distance increase, and to permit the verification of Part C for vehicles in the same virtual distance family to be combined between different Contracting Parties with their agreement, with such Contracting Parties considered as a single authority for verification purposes.

Japan proposes to add a specific requirement for vehicle speed measurement frequency of 20 Hz in Table A3/1 of Annex 3, consistent with UN R154; revise para. 2.4 to clarify that both constant and transient cycles test methods are permitted; delete redundant text from para. 2.4.1 regarding test cycle requirements; and delete from para. 5.1 the requirement that resolution and method for SOCE availability be determined in agreement with authorities, as these are already specified.

Proposal to improve efficiency of test methods by adding a reference to SAE J1349 or applicable local regulations, in addition to UN R85 and ISO 1585, to para. 6.1.2. and para. 6.1.2.1., and delete the requirement for Current integration measurement from para. 5.2.1. The additions provide consistency throughout the regulation and clarify that test results obtained in accordance with applicable local regulations are considered valid. The deletion removes an inconsistency whereby only Current integration measurement specifies a frequency of 20 Hz, while other items specify at least 10 Hz, and eliminates inapplicable wording carried over from UN R154.

Japan response to EVS action item 2: “All members identify specific questions in the white paper to contracting parties for agreement in order to continue with research.”

Proposal to include in the testing of REESS physical integrity such vehicle structural elements as may have an impact on test results. In other words, the manufacturer may request protective body elements to be included in the test set up.

The isolation monitoring system monitors the isolation resistance of the vehicle system periodically or continuously and warns if isolation loss is detected. Japan proposes this requirement in order to signal problems with isolation so the vehicle can be brought in for service before the failure reaches higher severity where the occupant could receive an electrical shock.
