Context / Purpose
In the case that the current Battery Box design would like to undergo a revision, it is important to determine what options are available to improve the thermal management of the Battery Box.
Things that can be relevant are:
Design geometry and spacing in assembly
Option to move certain entities inside the battery box
cells
boards
fans
Cooling methods
thermal design methods regarding any of the above entities
Things to keep in mind are:
limitations/constraints/hard limits of each entity
provide suggestions or ranking of options
Strategy
There might be some items on this page that overlaps with an existing deliverable.
In those cases, will either address or link to that documentation wherever more appropriate
Find research on the current geometry and locations of the battery box and its components inside
cells
boards
fans
etc.
Determine the amount of adjustability or wiggle room of each item found in step 1
Research cooling methods in context of
in general
battery box cooling (for electric vehicles)
electrical enclosure cooling
electronics cooling
Make summary of suggestions/ranking of options, and hard constraints of current design
Random notes to self:
for cooling methods, note that you can have bigger fans, etc.
then provide some resources that might help initiate that research or design process
create section for helpful resources found in step 4? or sprinkled across step 3?
probably step 4 and put it organized in a table and allow people to feel free to add
Research
Steps 1, 2 - Assembly Components Positional Design Space
This has overlaps with another assigned research tasks related to the specifications of the current Battery Box assembly. Some research will still be pursued here.
This will aim for more minimal references and research regarding this topic.

It has both front and rear electronics. It seems like the cell modules portion is in the front section only. The rear is for electronic boards.

Step 3 - Cooling Methods
This has overlaps with another assigned research tasks related to the specifications of the current Battery Box cooling methods. Some research will still be pursued here.
Larger focus on technical research and options available online.
