FMEA of secondary batteries
FMEA - Application Example for Cylindrical Lithium-Ion Secondary Batteries
Lithium-ion batteries are high-energy-density secondary batteries used in various fields such as onboard applications for HEVs and EVs, backup for power systems, and storage for renewable energy. As their range of use expands, safety has also become a focus of attention. Particularly, due to the high energy density of the batteries, caution is necessary as internal short circuits and thermal runaway can lead to major accidents. Against this backdrop, the quality of onboard batteries is regulated by the automotive-related standard IATF16949, and when exporting, the submission of documents (FMEA sheets) in accordance with the IATF16949 standard is mandatory. Additionally, for stationary secondary batteries, the safety standard IEC 62619 has been established. There are several shapes of lithium-ion batteries, but here we will explain cylindrical lithium-ion secondary batteries. The components of cylindrical lithium-ion secondary batteries can be broadly classified into eight elements.
