稼働データによる車載電池の健全度推定手法(第4報) 丸地 康平・山本 幸洋・波田野 寿昭(東芝) 運用時に入手できる稼働データ(電圧,電流,温度)から,車載電池の健全度(1C定電力放電容量)を算出する手法を紹介する.今回は,リパーパスの観点から車載以外の用途への適用性を評価する.劣化特徴量を適切に算出することで,太陽光発電の電力を蓄電する低圧BESSを模擬したセル実験データにも手法が機能することを示す. |

Demonstrating non-destructive safety diagnosis for lithium-ion battery modules based on charging curve analysis data Kenichiroh KOSHIKA (NTSEL)・Hideki TSURUGA (JET)・Tomokazu MORITA (TOSHIBA)・Keizoh HONDA (JET) A non-destructive 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 the lithium-ion battery cell and the cell operating condition 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 (SOH). An output image with comprehensive information including indicators to accumulate remaining battery performance value was also displayed. |
