Abstract

Aiming at a hidden safety issue, i.e. thermal runaway phenomenon, happening in the Li-ion power battery of pure electric vehicle, the process of one of most violent thermal runaway, i.e. that with nail penetration in a NCM Li-ion power battery is studied in this paper. Based on hybrid pulse power characteristic (HPPC) test, oven heating thermal runaway test and existing models, a lumped parameter model describing the process of nail penetration thermal runaway is built with corresponding experiments conducted. The prediction results with the model are validated by experiments. This lays a foundation for subsequent research and system development.
