We had the same issue. Our 120V circuit couldn't recharge fast enough overnight to handle ~ 50 miles daily of commute/errands. We ended up getting a 240V/40AM

We had the same issue. Our 120V circuit couldn't recharge fast enough overnight to handle ~ 50 miles daily of commute/errands. We ended up getting a 240V/40AMP circuit installed for a 32AMP charger and now it charges in ~ 3 hours. The faster charger also meant we could time it to always use the night time electricity rates.
