| 抄録(英) | A nondestructive safety diagnosis for lithium-ion battery modules was demonstrated with experimental data. The charging curve analysis (CCA) was selected for estimating the internal state of a lithium-ion battery cell and the cell operating conditions in a module. The safety threshold set by using CCA data was validated by thermal runaway tests for battery cells using an external heating method. The diagnosis for the module revealed not only its safety but also its discharge capacity (state of health (SOH)). An output image with comprehensive information including indicators to accumulate remaining battery performance values was successfully displayed. 翻訳 |
