alt Hacker News> LFP charging in cold has pretty much been solved by adding a heater to battery pack.
That's a hack, not a solution.

Wanna bet? LFP is ~1,000 GWh scale right now. GWh scale is 0.1%.

Why do you say that? It sounds like a simple solution to me.

Isn't starting a fire under your engine to get it to start a hack too? I mean they could add a heater to the engine. Wait.

After market electric engine heaters and remote starters are typical for ICE vehicles in cold climates (e.g. Alaska). Not sure why you consider this to be a hack for EVs if its builtin to the battery pack design.
I pulled into a Supercharger with my LFP-battery EV last winter. The temperature outside was -15C and I had not set the navigator so there was no pre-warming activated.
By the time I had finished my coffe, SoC had gone from 30-ish to 90-ish percent.
LFP tech anno 2023 is perfectly good enough for road tripping in large cars in severe winter conditions. For almost everyone.
