Re: Active cooling your leaf battery

Some of you are nuts to think you are going to cool the battery by soaking it in a pan of water.... NUTS!!

Re: Active cooling your leaf battery

If I may resurrect an old thread. I was thinking a couple of these piezo coolers pointed down the top of the battery with the radiator out front. One of the reviewe has his down to 55 degrees. What do you think?

Re: Active cooling your leaf battery

Welcome. I suspect that a device recommended for "pet cooling" isn't going to have the heat moving muscle needed to cool a Leaf battery. Nor will six of them.

Re: Active cooling your leaf battery

Back in the day, I needed to emergency cool down some old DEC10's as the air conditioning in the room had failed.
Pans of dry ice under and around the computers solved the problem nicely...

Re: Active cooling your leaf battery

Hi everyone, hope it's ok to reply to this old post, i have the leaf 2021 with 40Kv in israel and saffering of the same heating problem... I thought as a partial solution it might help to add a thin sealed tray under the battery and on one side there would be a connection to a thick tube (like a vacuum cleaner for example) which will be able to connect to one of the openings of the air conditioner and in addition there would be very small holes in the tray on the sides through which the air would exit, in my opinion this should help at least partially , I would be happy if anyone has an idea how to make this device in the most optimal way...

Re: Active cooling your leaf battery

In a hot climate, I think few options will offer much relief to force cool the battery unless you are willing to go I to the case. (I guess that leaves a drive to Mt Hermon for some cooling (Shavua Tov).

For cool climates, i found that 3 hours of passive cooling while driving efficiently at highway speeds does almost give you enough space for a reasonable charge. The issue is the top of the pack doesn't have any real airflow, so my curiosity is whether a smal fan mounted under the center rear hatch could help push air over the top of the pack (even just a little)to give me just a little more thermal space. I saw someone on facebook suggest placing cloths between the top.of the pack and the car, then using a spritzer to pull heat via the case. I don't like the idea of pouring water around the battery, even if sealed. My fear about dry ice, is that if the co2 leaks back into the cabin in volume, that might not be good for alertness.
