Introduction
This simulates scenarios such as road debris puncturing an electric vehicle battery pack or a tool accidentally damaging a cell. Based on the analysis of the current domestic and international standards for lithium-ion batteries in electric vehicles, this paper provides a detailed introduction to the composition and functions of lithium-ion batteries, describes the process and result determination method of needle puncture. It also aids manufacturers in designing safer batteries by understanding how they respond to extreme conditions. ASTM D882 outlines the tensile testing of thin plastic film, which is suitable for polymer separators.
