- Assume that the large difference in temperature distribution is indeed caused by a lack of air flowing over the cells
- Move the cells further apart in the middle in order to get more airflow through the module, essentially creating an airflow channel within the pack
- This is similar to what MSXII did by removing rows of cells inside the module
- Assume that making the cells as close together as possible (without touching - as we would run in to immediate thermal runaway propagation issues)
- We will aim for 0.5mm spacing, similar to the NASA battery pack design slides I have seen
- We must remember to leave room for thermistor and voltage taps to reach the hole in the top plate
- Have a 2mm gap between the cells in the series groups.
- We will put 2 channels through the module so that there are no more 'interior' cells, and that every cell has direct access to an airflow channel
The proposed new layout will be outlined below (once I get it done)
