Mark,
did you get an Ioniq5? What you described is what my Ioniq5 does.
There is a group of ESB chargers next to a Costa. At 20% I would plug it in and go to Costa and by the time I had bought my coffee and sat down and had a sip, the car was charged to 90%.
It all depends on what chargers you use. The Tesla chargers i can only get 120Kw max, it usually sits at 100kw. But some chargers are very rapid. Expensive but rapid.
Yes the Lead is a different car now. They had small batteries with appalling range, but the new ones being built are getting competative.
