Abstract(J)次世代 EV の充電システムとして非接触充電システムの比較評価を行っている。自動車への適用では,コイルの相対位置ずれ、およびギャップの変動に対してロバストであり、かつ漏洩磁界の少ない方式が求められる。本報告では、 EV 用の非接触充電システムの観点から、送電コイルの方式を比較検討したので報告する。

Translation

Abstract(E)In order to apply a wireless charging system to an automobile, there shall be robustness against relative position between a transmitter coil and a receiver coil.Also the leakage magnetic field of the system should be minimized. The mutual inductance(M)and the leakage magnetic field(Ф)of two different coil types have been calculated and compared.As a result of comparison of a solenoid type coil with a disk type coil, mutual inductance of the solenoid type is higher than that of the disk type,and the result is same for magnetic flux density.

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.
