It’ll be around 370 miles in a day, leaving and returning to home
If you are going somewhere, and then back again is there any charging at your stop(s)?
Destination charger (i.e. same as wall charger at home) will usually give you 7kW - that's about 25 MPH
13AMP plug is around 7 MPH
Depending how long you are stopping that might avoid a charging stop - you only need to charge just enough to get back home with, say, 10% for contingency.
Lunch? If you stop at Supercharger for 50 minutes that would charge from 10% to 95%+ - that much charge might enable you to skip a stop.
My calculations with ABetterRoutePlanner for MYLR at my chosen settings inc. motorway speed reckons on about 204 miles range. I'm sure that is pessimistic for UK - unlikely you would drive at 70MPH-plus-a-bit the whole way.
That would allow a (maximum) first leg of 183 miles (from 100% down to 10%)
Assuming charge to 80% subsequent legs would be 143 miles (from 80% down to 10%)
In practice chargers won't be perfectly placed! and you may choose to charge to less than 80% if next leg is short - optimum is to charge to about 70%, although it slows after that I personally think it worth charging to 80% as not much slower up to that point, and then less to charge at next top and also more contingency. Above 80% charging slows quite a lot, and above 90% dramatically slower.
So assuming ideal charger position your 370 mile journey is a first leg of 183, 2nd of 143 - and then 44 miles
Hence any top-up at your stop-over may well avoid a 2nd charging stop
You will get some extra range from having to slow for traffic / roadworks, and any roads on your journey which are not 70MPH dual carriageway
I aim to charge at the location nearest to my destination, because if I am held up in traffic / roadworks my speed will drop, and range increase. So at that "furthest" charging location I'll know, more accurately, how much I need to get to destination.
