very low. It's funny but last summer, the 2" of PIR around the batteries stopped them heating up as much as the garage air temp got to in the sunny afternoons!I'd think a few inches of foam would make heat loss negligibly low. For summer, need a manual or automatic vent opened.
I do I have temperature and SOC mappings... see...I don't think many, if any, of you have charge current adjustable based on temperature.
Science based discussion on charging LiFePO4 below 32°F
It wouldn't be hard for an engineer designing a BMS to scale charge current with temperature and state of charge. Seems like it could be done in firmware. For example: 10A@-10°C, 15A@-5°C, 20A@0°C, 30A@5°C, 40A@10°C, 100A@20°C. This would allow them to better protect the battery from damage at...
