but with a home charger this is not a problem unless you drive more than 220-240 miles each day.
Assuming you need to use it on consecutive days, you're probably in the realms of a max of 60-80 miles a day, if you want to use cheap rate home charging only.
From my experience, that's possibly a bit pessimistic. My lifetime average according to the app (which is close enough that I CBA to work out the actuals after the first 3 months of ownership) is apparently 3.1 miles per kwh, which means 217 miles per 'tank'. On a miles basis >90% of its work is motorway; either Telford -> Warwick (me), Telford -> Northampton (her) or 3 junctions up the M54 (School run). She drives everywhere on the speed limit, I drive at around 80 leptons when traffic permits, but given we commute, there's a fair bit of stop-start involved along with the poxy variable speed limits around Brummie land. If I have late meetings, speed goes up, range comes down, 1.7 miles per kwh is the worst I've seen iirc.

Octopus gives me 6hrs per day at 7p (down from 7.5p earlier this year) so that's a theoretical 42kwh per day, although admittedly its probably closer to 35 ish. Even so, the tesla would be more efficient (3.5+ miles per kwh at least) so should be able to maintain 120+ miles per day. Also, in fairness to Octopus, if I plug in when I get home at 7pm, they usually find more than 6hrs of cheap electricity between then and my usual leave time of around 5-5.30am.
