I was able to drive across the US in the winter in an Ioniq 6 without using Tesla chargers. All but a couple were 350V, WY was the worst state (NY->WA), battery conditioning had charges ~200V for the first phase until charge levels became the dominant factor. Ionna is 8 automakers building an alternative network https://www.ionna.com/founding-partners/ https://www.ionna.com/founding-partners/ Hyundai has their EV platform which has been 800V for a couple of years, future proof for the lifetime of the car considering how slow EV rollout is in the US...

  EV batteries charge much faster from 10% or 20% to 60%, maybe somewhat higher than that. Going from 20% to 80% typically takes as long as going from 80% to 100% and so standard advice is never to charge to 100% unless you absolutely have to. Every model has a charging curve, which I've never seen a manufacturer provide but some reviews do their own.

    I drive an EV, I asked because the comment genuinely didn’t make sense to me.

You're right that the poster used V when they meant KW but the Level 3 DC Charging Curve graph shows what I think they're describing: their EV charged at over 200 KW until the battery reached about 46%, then it slowed significantly again at 62 or 63%. Maybe TMI, sorry if so.

        I'll confirm I meant KW not V for the charging numbers The Ioniq 6 (Hyundai EV platform generally), charge from 20-80% in about 20m, which is on their 800v DC architecture

Yeah I've had an ID4 for a few years and its certainly possible, but seemingly overnight the charging network doubled and its a net win for everyone. Also, my mom is in her 70s, those CCS plugs are huge! I'm glad everyone was able to standardize on NACS.

That sounds wonderful. Our experience with an Ioniq 6 has been less spectacular. First of all, in winter the range drops from 520km to about 350km, and charging takes about 50% longer. Then when we took a long trip we only found one or two charging stations faster than 10kW every 300km. Many of the chargers were not functioning, some were on private property (e.g. car dealerships) and closed on Sundays, and none of them were rated at more than 100kW (and typically charging at about 70kW). The ones that were 100kW often had one or more cars waiting for them, so our 90-minute charge could have taken double that. The only exception was a Tesla supercharger station, but my wife refuses to support Elon Musk in any way, so that was out. This is in Southern Ontario, outside the Greater Toronto Area.
