I don't see the need for > 48A 99.9% of the time. Maybe if you're a rural realtor driving 400 miles/day with clients and need to do a major top-up over lunch? Not trying to be disparaging, but what is the actual need for > 48A? 48 is enough to charge any Tesla in < 10 hours (overnight) at home. In my 3+ years of electric driving I've yet to see a single L2 charger in the wild capable of more than 48A charge power, so no use there. Where did you guys use 72A, and to what benefit? I understand that there's theoretically a scenario where you roll in somewhere with a low charge and have to charge up and get back on the road, but even at 72A that's a PITA--more than 4 hours for 3/4 of a charge vs a bit over 6 at 48A. Both scenarios suck if that's the need.
I take back the comment about never having seen an L2 that can do > 48A. Some Tesla Destination Chargers can, but they're generally paired or in quad setups, and if even one other vehicle is charging, you're limited to 40A even in those scenarios.
I'm legitimately curious, as 48A seems like the clear call for Tesla to have made.
