Proposal for a UN GTR to provide a harmonized method by which the health of the electric vehicle battery can be monitored over time and by setting minimum performance requirements for the durability of the battery.

Illustration to support proposals explained in document GRPE-85-13.

Proposal to clarify the scope of Regulation 85 concerning electric drivetrains.

Proposal to harmonize:

• Requirements for the determination of CO2, fuel and electric energy consumption of the discharge requirement for OVC-HEV with an operating mode switch with its stop criterion.
• Preconditioning requirement (Annex 9, determination of electric range) and UN R83 (Annex 14, provisions for emissions test procedures for HEV).

Proposal to permit the use of hydrogen (H2) as fuel for type approval of heavy-duty vehicles.

Proposal to correct the recursive formula in the procedure for verifying the conformity of production requirements if the production standard deviation given by the manufacturer is either not satisfactory or not available.

Proposal to correct the recursive formula of the 05, 06 and 07 series of amendments to UN Regulation No. 83 in the procedure for verifying the conformity of production requirements if the production standard deviation given by the manufacturer is either not satisfactory or not available.

The use of test fuels is permitted for certification testing of gaseous and particulate pollutants and power/smoke testing in Europe. However, other countries that have adopted and referenced UN R24 may not allow this. This proposal would permit the use of the same test fuel in cases where the testing for emission of gaseous and particulate pollutants is conducted at the same time as the testing under UN R24.
