Overview of task force issues and objectives concerning malfunction diagnostics and driver/occupant hazard warnings specific to battery electric vehicles.

Draft text for a heavy vehicle annex to the proposed global technical regulation on electric vehicle safety requirements.

Presentation concerning the definition of internal short circuit and proposals for thermal runaway/internal short-circuit test and thermal propagation test.

Proposals concerning post-crash safety and vibration requirements.

Proposal to extend the EPPR informal working group mandate into 2020 in order to permit the group to cover the full range of identified emissions and fuel consumption issues related to the full range of motorcycle and related light vehicles (Category 3/Category L).

Update on the JRC comprehensive environmental effects study to evaluate the air quality and the share of pollutants contributed by L-category vehicles, covering the requirements of test types I, III, IV, V, VII and VIII.

Revised version based on document GRPE-70-19.

Proposal to align the tyre-selection criteria in the CO2 emissions/fuel consumption tests under UN R101 with those for pollutant emissions (UN R83).

Proposal to correct the unit of the road load coefficient b used in the formula for the calculation of the resistance to progress force.

Proposal for a set of uniform terms and definitions to promote consistency across powertrain-related regulations.

Proposal to clarify the determination of net power in cases where an additional fan or other method is used to maintain the temperature of the engine coolant within the prescribed range.

Proposal to avoid a redundant correction of the measured engine power of supercharged and turbocharged engines fitted with a self-correcting system for ambient conditions such as temperature and altitude. The current correction factor may yield inaccurate results for such configurations.
