Research paper concerning the life-cycle CO2 emissions per mile traveled for plug-in hybrid electric vehicles (PHEVs) and battery electric vehicles (BEVs) across the United States. The authors found large variations in the estimates across regions, charging schemes (for example, higher use of coal to generate power during overnight charging), and vehicle models (including differing relative results between models under different regional charging scenarios).

Proposal to include visual/audible inspections of batteries and pass/fail criteria throughout the electric vehicle safety test procedures in order to address risks associated with the release of flammable and toxic gases intended to relieve internal pressure and avoid battery ruptures or explosion.

At the 8th EVS GTR IWG meeting in Changchun, members of EVS Task Force 1 continued to discuss proposed requirements and test procedures (EVS-08-17) to address the safety performance of EVs during in-use in events of flooding and vehicle washing. As an action item, members were requested to provide comments on the overall proposal, specifically, water depth (10cm) and vehicle speed (20 km/h) for the drive test. The US believes that a 10 cm water depth test presents a reasonable and likely scenario for testing electric vehicle performance.

OICA views concerning thermal propagation risks and the need for testing to evaluate such risks.
