I do approx 200 miles per week, so have worked out I'd only need to charge once a week for 1-2 hours which is easily doable. It would cost around £35 per month which is still much cheaper than petrol in any case so cost isn't the issue.
People often work out their anticipated need for charging like you describe. "Because I don't do too many miles in a week I will only need to charge once." This seems reasonable when you are still thinking in a petrol/diesel frame of mind where you generally fill a tank then run it low before filling it again.
If you don't have home charging then perhaps charging at work can be an option. If you need to rely on public chargers you need reliable ready access to local charging 2 or 3 times a week in my opinion.
I'll outline some of my thoughts...
An EV works best when frequently topped up to give you 90% of its rated range
every day. Being plugged in when not in use is what Tesla recommends. For best battery health it's recommended not to routinely charge to higher than 90% nor run the car routinely below 10%. It's easy to keep within those recommendations and live without "range anxiety" if you charge regularly but not if you charge once a week.
Charging once a week could be difficult and at worst take away some of the pleasure of EV ownership. You definitely need the reliable availability of charging 2 or 3 times a week even if you don't always think you need it. Firstly can you really say that your car usage is so reliable and consistent that you will be happy starting the last day of the week only having, say, 10 miles of range? Maybe you think yes because after all your final journey is only 7 miles. Life isn't as tidy as all that. The car doesn't just use power driving along, it loses a little every time you stop and start. It loses a bit overnight ... it loses more when it's cold ... it uses more when you need to drive in strong wind and rain ... the battery may be lower because you needed to give a friend a lift to their work or made another unplanned excursion or simply because it was a beautiful evening and you wanted to drive out to the country. Your car may well easily exceed 200 miles if charged to 100% and run to a low percentage in one long journey but maybe not so easy spread across a week and sticking within that optimum 80% band (10 to 90). One time you have 30 miles left at the end of the week and another you have none. And public chargers can be notoriously unreliable ... yet you REALLY need that charge if running the battery low. (And that's when your sceptical friend suggests meeting up and you have to admit that you can't because your fantastic new Tesla has no "juice" ... oh how they laugh!)
Perhaps I'm being a little pessimistic and others are successfully doing a regular 200 miles a week with a single public charge ... I would be interested to know but the idea doesn't attract me.
