A couple of years back, we got a Bolt and had a bunch of electrical work done to support charging in the garage. Current state:
- 200A service to the house, with a freshly rebuilt panel
- Solar with battery backup (Enphase equipment)
- 100A subpanel in the garage (significant loads: freezer, garage door openers, EVSE)
- Old dumb Siemens EVSE on a 50A circuit on the subpanel (plugged in)
- Emporia Vue monitors in the main panel and subpanel
Now we're getting a second EV, so we want a second charger. I believe we have plenty of load overhead in the 200A service for this, but not in the 100A subpanel in the garage. We don't actually put that many miles on our cars, so restricting the charging
