Abstract(J)走行中給電システムは車両の床下やアップライト部,ホイール内に受電コイルを搭載し,車両の走行中に電力の伝送を行う。そのため,コイルの装着位置によっては,走行中の加減速や路面の凹凸,乗車人数による重量変化により電力伝送へ影響を与える。本稿では,実走行時の荷重変化によるサスペンション変動やタイヤの変形などを考慮して,コイルの搭載位置によるコイル間ギャップの変動量を定量化する。また,実験結果から電力伝送へ与える影響を明らかにする。

Translation

Abstract(E)DWT have a receiving coil mounted on the vehicle and transmit power while the vehicle is in driving. Therefore, depending on coil mounting position, the gap between the coils may change due to acceleration/deceleration, unevenness of the road surface, and weight change caused by the number of passengers. In this paper, we clarify the amount of variation of the gap between coils and its effect on the power from the suspension variation and tire deformation during actual driving.

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.
