Hey I mean credit where credit’s due. If they can somehow cram a 200kWh battery with megawatt charging to get 700 miles and 10 minute charges into a Toyota priced car, so be it. Can’t imagine that’d be possible since that would be like 20-30k in battery cost alone, and there aren’t any chargers who can deliver that kind of power right now anyway.
At 350kW peak, I wonder what the miles per kwh would need to be to charge 700 miles of range in 10 minutes. That’s 58.3kWh delivered. So uhhhh they’d need to get 12 miles per kwh which would be uhhhh nuts
10 minutes at 350kw (assuming you hold peak the whole time) would provide
If we correct for toyota falseadvertising range estimates (-10%), assume they mean 90km/h at similar consumption as a model 3 in ideal coditios (around 120Wh/km), and take "a charge" as 10-80% then it needs 90kWh or about half a megawatt.
So still not within current chargers, but well within what a megawatt charger would provide (and there are four standards basically ready to roll out).
