Scope: This standard specifies the basis for the quantitative assessment of the hazardousness of power batteries. This standard applies to the assessment of the hazardousness of power batteries and power battery-equipped vehicles, and can provide a reference for the quantitative assessment of the hazardousness of other battery systems. Main technical content: This standard consists of a preface, scope, normative reference documents, terms and definitions, grading principles, grading basis, hazardousness grading, and hazardousness index calculation. This standard quantitatively grades the toxic, harmful, and flammable/explosive substances released by power batteries after thermal runaway caused by internal factors (internal short-circuits, self-heating) or external factors (collisions, squeezing, heating, etc.), as well as the potential fire and toxic hazards and adverse impacts on the environment and human health. The hazardousness grading of power batteries (toxic substances) is obtained by using the toxicity hazard index (THIP) and exposure level (CR) based on risk assessment methods. The test methods involved in this standard were obtained through ten years of research, multiple experiments, and product verification by several enterprises. The relevant technologies in this standard mainly involve thermal runaway triggering technology and leakage detection and analysis technology. All leaked substances detected by instruments have been calibrated against internal and external standard materials.
