Abstract(E)Thermal management of the lithium-ion battery in the hybrid and battery electric vehicle, which controls the battery temperature, is important to counteract battery degradation and overheating. In the previous report, we optimized the thermal and power management control of the series hybrid electric vehicle using a vehicle system 1D simulation model and optimization method. In this report, we implemented the engine thermal model and improved the reinforcement learning method. Then, we optimized the thermal and power management control, and subsequently analyzed the battery heating performance and fuel consumption performance at low temperatures.

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.
