Abstract(J)車載蓄電池の健全度(1C定電力充電容量)を実運用時に入手できる稼働データ(電圧、電流、温度)のみから算出する手法を紹介する。特別な計測や機器を必要とせず診断できることが特長である。
昨年度は公共交通を模擬したセル実験データを用いて評価したが、今回はEVバスの実稼働データに適用し、手法の有効性を示す。

Translation

Abstract(E)We proposed SoH estimation method for on-board lithium-ion batteries using operation data such as voltage, current, and temperature.
This method estimates battery capacity by referring statistically to operation data from deteriorated battery cells and does not require special measurement or equipment.
The effectiveness of the method was evaluated by actual operation data of EV busses.

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.
