EV fire fighting tech ... interesting product

I have burned those lithium AA cells, very anticlimatic. They just kind of burned.

At the very least, they can’t be carried in checked in baggage. I suppose the idea is that if they catch on fire they’re where someone can attempt to extinguish the fire.

So this happens daily?

Does it actually happen during charging? How often? Frequency is important.

I've been dealing with LiFePO4 and LiCoO2 batteries for bikes from three different sellers for years now, some of the earliest (2013ish??) flat cells were extremely sketchy yes they were LiFePO4. Most all forms were duct taped ultra power dense rectangles and triangles. Charge the heck out of them. Use them hard. Sometimes cells died.

Never once was there a fire or uncontrolled release of energy with any type.

I'm not saying they can't be dangerous and the fires are rapid and nasty, but wow some of the experts here are way way over the top.

LiFePO4 are too cold sensitive, won't be used in an electric car. Plug in hybrid sure.

Tesla is already using them. My parents bought a 2023 Model 3 RWD. It's easy to tell when the charging slider recommends keeping the max charge level at 100%. Other versions recommend 90%. They have it charged to 100% once a week but have it at 90% most of the time.

No wonder they brick in extreme cold.

News to me. I have one and we live in the Midwest. Battery life isn't great in deep winter, but no EV is.
