Abstract(J)劣化履歴の異なるセルにより構成されたリパーパスを模擬した組電池を作製し,サイクル劣化試験を実施した.組電池および各セルのSOHとセルバランスを推定する非破壊診断として充電曲線解析およびセルOCV-SOCに基づく推定手法を用いて組電池の劣化状態推定し,組電池実測容量と比較して推定精度を評価した.

Translation

Abstract(E)A battery pack emulating a repurposed battery, composed of cells with different degradation histories, was fabricated, and cycle degradation tests were conducted. As a non-destructive diagnostic method to estimate the state of health (SOH) and cell balance of the battery pack and each cell, the degradation state of the battery pack was estimated using charging curve analysis and estimation methods based on cell OCV-SOC. The estimation accuracy was evaluated by comparing the estimation results with the measured capacity of the battery pack.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
