EVS Task Force 5 includes testing for thermal propagation risks.

Review of work towards adapting and/or approving certain UN Regulations for use within the International Whole Vehicle Type Approval regulation.

OICA proposals for test procedures for thermal propagation.

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

OICA proposals for battery management system testing.

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.

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.
