US and Canada position on the draft fire exposure test for electric vehicles. Pursuant to Canadian testing, the US and Canada do not see a need for additional testing of electric vehicles (as opposed to ICE vehicles) because the battery and electric systems do not show any cause for special concern in vehicle fires. Battery pack testing could be considered in a later phase in the development of the safety regulation if warranted.

Proposed justifications for inclusion of testing of electric vehicle systems against water infiltration as well as for exemption from such testing.

OICA proposals for test procedures for thermal propagation.

OICA proposals for battery management system testing.

OICA argument for delaying the establishment of water testing until the “phase 2” development of the electric vehicle safety test cycle.

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.

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 for the final draft REESS pass/fail requirements under test procedures for assessing risks associated with electrolyte leakage and gas venting, for incorporation into the proposed electric vehicle safety GTR.

EVS TF5 draft text as agreed to date for a test procedure to assess the performance of the REESS in the event of thermal runaway by a single cell. The intent is to safeguard against thermal propagation that could result in a system fire or explosion.

China positions on the justification and development of thermal propagation testing.

NHTSA note proposing that the specific battery SOC measurement procedure be determined by manufacturer in accordance with the battery design.

Task force chairman’s review of the current text and action items.

Proposed text for a sequential testing program to test the Battery Management System (BMS) response at the safety boundary limits of the REESS during operation. The test evaluates the ability of the vehicle’s BMS to safely monitor and control the REESS under external inputs such that there is no damage to the REESS and no hazardous conditions arise.

EVS Task Force 5 draft text as of 1 March 2016. This updated version was posted on 17 May.

Proposal based on SAE test procedures for drop testing and rotation (rollover) testing.

Presentation on fire resistance testing using gasoline instead of propane.

Presentation concerning an electric bus fire in 2009 reported by a Chinese research institute.
