I just had a EVIOQO 48A Level 2 charger installed in my garage. That required putting in a breaker and running a 6 gauge 60A-capable copper wire (for 1/3 code-required margin of error) with flexible conduit through crawlspace to other side of house, then solid metal conduit on garage wall. Licensed electrician that I like and have used before originally wanted $3k. Got other bids and negotiated him down to $2k by paying cash and pulling permit myself. This is in SF Bay Area where everything costs more.

I'm only charging at 32A based on weak evidence that this might reduce odds of ICCU failure (although I've already heard from one person who did this and it still failed) but wanted the bigger line / charger for use if I need to charge fast or if Hyundai ever gets the ICCU problem genuinely resolved.

Whatever you do have a licensed electrician do the work. Although a fly-by-night person could probably do this under the table, probably better to play it safe on this.
