Lithium Ion Battery Home Fire

[solardreamer]

I personally have Tesla PowerWalls in my basement and tried to reduce combustibility around batteries. Large LiIo batteries do have some risks but it is sufficiently managed by having partial isolation of individual elements inside batteries, temperature probes, cooling liquid and electronic monitoring of charging process.

Is your PW covered by home insurance? If so, what's the associated premium?

Personally, I would never put a large Li-ion battery inside my house unattended. LIFePo4 would be OK. Growing number of jurisdictions no longer allow indoor installation of home batteries.

My personal opinion that NG or propane line to the house has higher risk profile than LIIo storage battery.

Why?

I do not think water should be used for LIIo battery fires. Water interacts with Li and produces oxygen. Unfortunately many fire departments do not know how to deal with this this type of fires and by using water make a problem worse.

Commercial installations are substantially larger than residential batteries so it makes senses that spacing and placement requirements are different.

Lithium ion battery causes house fire in Sanbornton Saturday | Local News | laconiadailysun.com

I see all the posts on all the folks building home battery setups where the batteries are obviously in a house and cringe. On commercial jobs whenever we looked at large Lithium batteries we needed to have them outdoors with plenty of space around them and a nearby fire hydrant.
