Proposal for establishing two informal working groups addressing the safety and environmental requirements for electric vehicles to enhance regulatory cooperation including developing global technical regulations in the framework of the 1998 Agreement.

Final proposal prepared by the informal working group on the scope, objectives, and timetable for consideration of the environmental impact of electric vehicles and possible regulatory needs. This group expects to supplement the existing efforts of the WLTP, HDH, EFV, VPSD, and EVS informal groups.

Japanese comments on the recommendations/guidelines proposed in the draft electric vehicle environmental regulations reference guide.

Questionnaire presented to Contracting Parties to the 1998 Agreement to gather views on areas to be addressed in the next phase in the development of the global test procedures related to light vehicle emissions.

Presentation of potential areas for the further development of the global regulation on light vehicle emissions, including test procedures regarding low ambient temperatures, high altitude testing, in service conformity, and durability of catalyst, DPF, and SCR systems as well as electrified vehicle batteries and motors.

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.

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.

Presentation of Japanese research into a normalization method to compensate for tolerances allowed under the proposed hybrid electric vehicle emissions and energy consumption test procedures.
