500 kW charging. Hardware is basically feature complete at this point, not much incremental utility to going above 500 kW. Proliferation and vehicle improvement will be the focal point now.

I may be in the minority but I don't think larger battery packs are the game changer. Charging speed and proliferation of fast chargers is what is going to be most relevant. A larger pack only helps you with the first part of a long trip as it will just take that much longer to charge at each stop. 300 mile range seems like the sweet spot, specifically if they can get charging down to roughly 10 minutes. If they get charging speed down I'd prefer an LFP pack getting around 275 miles than an NMC getting 350 for the increased life of the battery and safety.

Faster charging, smaller, solid state batteries with less cooling requirements but more energy density would be a great thing. Doubt that happens near term at all, though.

Yeah, but at 500 kW power the limiter is on the vehicle side, not the charger side. At 500 kW a Lucid Air at peak charge rate adds about 40 miles/minute. The limiter is how long that can be sustained, which is a function of battery size/thermal management.

An 85 kWh pack being the standard to balance size/cost/thermals with efficiency gaining to ~5 miles per kWh gets you 425 miles of range. Sustained charging at 500 kW to 50% gains you 212 miles of range in 5 minutes. In other words ~3 hours of driving for every charging stop.


500 kW is enough power, better batteries and more efficient motors is the limiter. 1000 kW power would just mean blasting to thermal limits faster and would speed up charging minimally.

I have more people use the manual latch than the button on the Model Y, which is irritating because the manual specifically states repeated use of the latch can cause damage.

Reading a car manual to learn how to open the door. Yeah, people not reading is the problem. eyes rolling.

you don't need to read the manual - if you use the latch it tells you on the screen that repeated use could damage the latch.

Yes, I'm not referring to max charging speed. I'm saying the game changer isn't higher capacity batteries but rather overall charging speed. Part of that game charger likely is continued focus on battery technology, but that doesn't need to be capacity oriented.
