That fire extinguisher looks ridiculously useless for a setup like this. Good thing it's a separate shed, at least.

I experienced a 400v DC lithium ion battery catch on fire once, it was very scary. That fire extinguisher won't do much at all, even if it is placed in a more logical spot.

The firemen ended up putting the battery, half melted, into a big drum of water and it hook hours to cool off. The concrete was still warm to the touch where it burned for ~30 hours after the situation was sorted out.

The smoke was just absolutely unbelievable. Made me reconsider buying an EV. That fire was no joke.

The MV contactor wasn't even closed, it had 24v powering it for the internal cell balancer from the vendor, that was it.

Even though it might not seem like it because reporting on burning cars is very selective, EVs do catch fire a lot less than gar powered cars - even when adjusted for how many there are on the road. Additinally, many new EVs use cheaper LFP batteries now that are almost impossible catch on fire.

I hear you and appreciate your point, I just don’t think they’re for me. Maybe when my kids are grown. Scary does t begin to describe what happens, the amount of energy is mind-boggling.
