Abstract(J)電動車に搭載される駆動用リチウムイオン電池(LIB)の発熱・温度挙動予測は,電動車開発および電池開発の両面において重要である.本研究では市販EV用LIBを用いて充放電時の発熱および伝熱モデルを構築し,実測値との比較検証を行った.さらに,次世代電池として期待される全固体LIBの温度シミュレーションについて検討した.

Translation

Abstract(E)Predicting the thermal behavior of lithium-ion batteries (LIBs) for electric vehicles is necessary for development of both electric vehicles and LIBs. In this study, we constructed a heat generation model during battery charging and discharging and heat transfer model using LIBs of a commercially available electric vehicle. The validation of the model was confirmed using the experimental data. Furthermore, we applied the model to an all-solid-state LIB under development.

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.
