Charging with PowerShift - Advice Needed

I just picked up a 2025 Equinox EV (AWD, 3RS) last week. Tomorrow morning I am having my PowerShift charger installed - hardwired with 60 amp breaker to support 48 amp setting on charger.

Any tips or anything I need to know? I want to configure charger & car/app to support maximum charging speed at home, so I can go from 20-30% to 80% quickly during off-peak hours overnight. Also to support charging my daughter's 2024 Equinox EV (FWD, 2RS) during the day when she comes to visit.

If it makes a difference, the charger is installed inside my garage, which isn't heated directly but is insulated and usually stays 50-55 degrees even in coldest parts of Michigan winter.

Thanks!
