Abstract(E)	Battery size is crucial for electric vehicles, affecting range and cost. The article explores technologies to reduce battery size and cost, avoiding the race for larger batteries. It assesses the impact of charging infrastructure and high-performance charging on battery capacity. Efficiency considerations, such as thermal management and using waste energy, are evaluated to reduce electrical consumption. Additionally, the influence of new battery chemistries and technologies on energy consumption and fast charging cycles is discussed. The goal is to find solutions that optimize battery use without compromising vehicle performance or increasing costs.

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".
