The purpose of this document is to facilitate arrival at a common understanding among EVS informal group contracting parties on thermal runaway propagation risk assessment. Several contracting parties are embarking on a thermal runaway propagation experimental research campaigns for Phase 2 and a common understanding is important to help focus research efforts especially considering the complexity of cost-intensive thermal propagation tests. This approach is expected to further facilitate coordination of contracting parties’ research and to pave a path for effective round-robin testing. For this purpose, this document contains a non-exhaustive list of questions for discussion and agreement among experts.

6. Thermal propagation and methods of initiation in battery system
7. Post-crash REESS safety assessment and stabilization procedures
8. Light electric vehicles (e.g. categories L6 and L7, low speed vehicles)
9. Protection during Alternating Current and Direct Current charging and feeding process
10. Overcurrent requirements plus tests (component based).
