Is this because of stories of EV's catching fire? Hard to know what to make of that. There have been some instances reported but they haven't been given much media traction, maybe because they've been pretty rare and maybe there have been extenuating circumstances that were not reported (?)If'n it involves charging a lithium-ion battery I ain't doing it. In my house/garage anyway. I have a neighbor with a new Jeep (the big one). She gets home when we are walking and plugs it in on her driveway. I still ain't doing it. Joe
Given how hard it is to extinguish a lithium battery pack, it might be a concern, though. The big problem is that the batteries are in a sealed container and it's impossible to get the veryconsiderable amount of water required onto the actual batteries to cool them and control thermal runaway. One manufacturer of commercial firefighting equipment has come up with a very high-pressure water nozzle that can penetrate the battery compartment for this reason.
If fire really is a significant risk, I'd think that the battery compartments might have to be made in such a way as to for proper extinguishing, and/or a mandatory extinguishing system being installed. Which will of course put up the price even more....
