Abstract(J)	BEVの充電に伴う発電所からのCO₂排出量の算出には全電源平均の排出係数を用いることが多いが、充電によるCO₂排出量の増加を求める計算には使えない。ここでは、電源別の発電量の調整を考慮した算出方法を紹介する。その上で、再エネを利用して実際にカーボンニュートラル走行を実現するための考え方を述べる。 Translation
Abstract(E)	The average emission factor for all power sources is often used to calculate the CO₂ emissions from power plants associated with recharging BEVs, but it cannot be used to calculate the increase in CO₂ emissions due to recharging. Here, we introduce a calculation method that takes into account the adjustment of power generation by power source. Then, we will discuss the concept of actually achieving carbon-neutral driving by using renewable energy.

About search

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.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
