I just ordered my first Tesla (75D), which should be here in June. I'm trying to get my charging situation squared away, and I'd love some input.
I work at home, so I don't have a regular commute to worry about.
My house has a 125A main breaker, and my electrician determined I have 26A of capacity available. Further, there are no empty slots in my panel for additional breakers (ugh). So, my options come down to the following:
Option 1 - install a 30A circuit to the garage; this will require addition of a new sub-panel, as there are no open slots for new breakers on the existing panel. Total cost for this option will be roughly $1200, including a 14-30 adapter. A downside here is I've spent $1200, and I'd still need to pay almost all of the cost of option 2 to upgrade service any higher - all of the costs for the option 1 subpanel are throwaway in that case. Charge rate would be 26A, around 17 mph.
Option 2 - upgrade service to house to 200A, and install 50A service to the garage. This requires a new panel, along with all of the new requirements to meet code (new meter housing, etc.). This would come to about $2750, and would provide 40A charging.
Option 2a - I think if I go with option 2, I'd probably add a HPWC for an incremental $500, just for the convenience. I'd presumably wire it in at 60A, so I could charge at 48A.
Option 3 - I'm not really considering this - but if I replaced my electric range with gas, that would free up enough capacity to run 50A to the garage with no further upgrades. Cost here about $800 plus buying a new range, plus buying other new kitchen appliances to match the shiny new range, plus new granite countertops...ha. Clearly an expensive way to go.
Any thoughts?
