The 98th EVE IWG session held virtually on July 15, 2026, adopted the agenda and discussed Phase 4 priorities for UN GTR 22, including Minimum Performance Requirements, State of Certified Range, conditioning cycles, and mutual recognition. Japan proposed sharing Part C verification results with all Contracting Parties. The IWG reviewed UN GTR 21 and UN GTR 25 status, covering MPRs, energy throughput, virtual distance verification, and battery replacement provisions. OICA will present their MPR position at EVE 100 and share Part C verification results at EVE 99. Japan will consult on hosting 2027 meetings targeting the week of February 15th.

The agenda for the Electric Vehicles and the Environment Informal Working Group 98th session scheduled for July 15, 2026, includes presentations on battery performance, discussions on UN GTR 21, UN GTR 22, and UN GTR 25 regulatory topics including minimum performance requirements, state of charge reference, readiness monitor and conditioning cycles, mutual recognition, fuel cell electric vehicles, highly integrated systems, energy throughput, normal usage indices, and battery replacement provisions. UN GTR 25 amendment 2 must be submitted to March 2027 GRPE with a December 2026 deadline.

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.

Proposal to add two new definitions to para. 3.30., modify para. 5.1. to require manufacturers provide a procedure for achieving recent SOCE/SOCR monitor updates, modify Annex 1 to establish monitoring based on new parameters rather than the 50 per cent state-of-charge threshold, and add mandatory values to Annex 2 including State of Certified Energy Readiness Status, Energy Storage System Recent Depth of Discharge Counter, and Preconditions for Recent Battery Capacity Update, based on GRPE/2026/5 and EVE-97-04e.
