The average battery size for the Model S is probably 85kWh (they sell them from 70 - 90), and average residential power rates in the US are ~$0.15/kWh. So the easy answer is, a Model S will cost ~$12.75 to "fill up". However, some places have residential rates closer to $0.08/kWh, or $7/tank. That's for 300mi range.
They do sell lower capacity battery versions and the entry level Model 3 will likely have a 50kWh battery for a 215mi range, so that would cost $7.50 to fill.
Most areas have night-time plans from the utilities to level demand where they charge a lot less for power, the Supercharging stations are free to use for Tesla owners, so the average cost will probably be quite a bit lower.
- raisedbyninjas 11y agoDoes the Tesla come with charge management settings to specify how much and when it charges? Some residents have power plans with reduced or free electricity during off peak. Mine is free on weekends for example and I usually only drive 150 miles/week. I could theoretically charge for free and always have a least a hundred miles range during the week. It would be nice if I didn't have manually schedule this.
- tlb 11y agoIt has a daily schedule: I set mine to charge after 11pm when rates are low. I haven't seen a weekly schedule.
- ryanhuff 11y agoPower rates vary widely in the US. In Southern California, I am above $0.30/kWh. I haven't done the math recently, but I don't think it's very cost competitive with today's gasoline prices for an ICE.
