The real issue here is to prevent thermal runaway.
I would go further, and add a thermal cutoff switch to turn off the battery charging if it's too warm outside (We've had summer days here at 115F.) Then maybe a fire suppression system of some sort.
- semi-extrinsic 9y agoFire supression should be pretty easy in this configuration. Get a 55 gallon drum of deionised water, put it on top of you battery shack, feed a plastic hose from the bottom of the tank into the shed and seal the hose with a plastic that melts at, say, 150 F.
- switchbak 9y agoWith all the recommendations of mods, custom PCBs, sheds, cinderblock enclosures, underground bomb shelters, etc - the $5500 Tesla PowerWall doesn't sound so bad at all! Edit: removed concern about deionized water.
- bb88 9y agoWe really need a battery that's high capacity and doesn't explode.
