Abstract(J)本講では、電池特性を擬似化した等価回路の抵抗や容量因子として把握する高速パルス装置を紹介する。μ秒から秒までのパルス過渡応答のデータベース(DB)を計測対象電池で予め作成しておけば、これを基とした機械学習的診断で、LIB の劣化評価を1秒で遂行できる。車載モジュールや多数個セルへの本法の適用例を紹介する。

Translation

Abstract(E)The presen tation introduce s a high speed pulse device that considers battery characteristics as resistance and capacitance factors of equivalent circuits that simulate them. If a database (DB) of pulse transient response from μ seconds to seco nds is created in advance on the target battery, the deterioration evaluation of LIB can be performed at the speed of a second by machine learning diagnosis based on this. Examples of application of this method to automotive modules and multiple cells are introduced.

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.
