My impression was that Hyundai/Kia EVs can take much more than 150kW — more like 350kW. Since 350kW chargers aren't yet common, I don't consider that an advantage when thinking about purchasing. There are plenty of EVs that charge in the neighborhood of 150kW, and a lot more chargers that are able to provide that throughput.
They peak at ~245kW. Charging from a 150kW charger isn't too bad either, because they can sustain that speed most of the time (unlike cars advertising 150kW max where it is only a peak of the curve, and the average is less).
For road trips charging speed is IMHO even more important than the range. My breaks take 20-25 min typically anyway, but a 45-minute car would keep me waiting.
