Recommendations of the task force on heavy electric vehicles.

Recommendations of the task force on the application to heavy-duty commercial vehicles of the proposed electric vehicle test procedures/requirements.

Presentation on Chinese research related to battery management systems and risks, including pending Chinese regulation on safety requirements and test procedures for lithium-ion battery systems and vehicles.

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.

The purpose of the testing is to stress a rechargeable energy storage system (REESS) from both an electrical and mechanical standpoint to verify that there are no safety issues that arise from mechanical shock, vibration and temperature excursions in real world applications.

Includes proposal on thermal propagation test method.

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

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.

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.
