Proposal EV/PHEV/HEV/FCV Lab Process Sub-Group Schedule and Process for development of test procedures SWEDISH TRANSPORT AGENCY JASIC Japan Automobile Standards Internationalization Center

- Proposal- Schedule 1st Phase Based on WLTP-DTP-01-03 One and half years process for EV/PHEV/HEV/FCV Sub-Group Finalize draft test procedures by the end of Sep. 2011, Start validation tests from the beginning of Oct. 2011. 2 phases approach Develop draft test procedures. Discuss/Refine test procedures by overall review. 1st Phase 4 step approach What performance values are necessary? / What procedures (tests, calculations, etc.) are necessary? (Added by conference call on 2010/6/16); divide each procedure among each sub-gr to prevent duplicated job. Making Comparison table of already existing procedures Review documents to understand the current procedures of each reg. Establishing a draft of test procedures .

Initial common test procedures proposal 2. Refine Step 1.Make a list of performance values & test procedures, divide to each sub-gr. To consider what performance values are necessary to evaluate exhaust emissions and fuel economy. To consider what procedure is necessary for each performance value. To prevent duplicated job Step 2.Make a comparison table of already existing procedures. Step 3.Review of the comparison table. To analyze current procedures deeply Step 4.Establishing draft test procedures.

Initial Process prior to the Step-1 of Phase-1 To make consensus with regard to roadmap for E-Lab process with Leading-team. To make consensus with regard to roadmap for E-Lab process with members. To make common database to upload related electric files for E-Lab process Sub-Gr. 6 7 8 9 10 07 14 21 28 05 12 19 26 02 09 16 23 30 06 13 20 27 04 11 18 25 2nd DTP 3rd DTP Review roadmap proposal by STA Refine the roadmap Distribute the roadmap to members / ICE leaders Refine the roadmap Conference with ICE leaders Proceed step 1 Proceed step 2 Proceed step 3 Make common database for E-Lab Process Sub-Gr * Periodical conference will be set for information sharing among sub-group leaders. * Information will be shared with e-mail basically. Conference call will be set up if necessary. ** Face to face meeting may be set in conjunction with the 3rd DTP for final revision of Sub-Group report & discussion of common test procedure.
