It would not work the same. Right now I am pumping 62F air directly at the top cover of the battery pack. My garage ambient temp is 83F with 90F air outside. I would have to cool the entire garage down to 62F to get equivalent battery cooling effect. My entire house it at 77 - 79F. I do not think just blowing ambient air around the battery pack would be enough to be worth it. It would work if I did not drive it 60 miles almost every day. But just charging the battery raises it's temp by ~5F, then the drive by another ~10F. With just ambient air it would not have enough delta T to cool the battery cells to a meaningful result in 16 hours.

I am now at 54.92 Ah, 86% SOH, 78.17% Hx, (33,202mi on 295B0-3NF9E battery).
