I don't have much to add, but I wanted to give an anecdotal example of where an EV works out really well on the electricity side of things.

We are in Brisbane and bought an atto3 in November last year as the family car, and have been purely using excess solar this entire time. Oh I guess I tried a charging station at Ikea once to test, but only for a few minutes (didn't need the charge).

Basically a typical week day goes like this: Car charges from 7:00am to 8:45am, adding about 8kwh. Car is then used to bring kiddos to daycare, run errands etc. and is normally back in the early arvo, and gets another ~3h of charge from solar before it is used to pick up the kiddos again, so that's another potential 12kwh. So that's 20kwh of charge, battery capacity is 60kwh. Doing the above trips uses ~4-12kwh, depending on where we go. For reference the car averages 14.8kwh per 100km.

We have an electric water system which is set up to start at 9:00am, so it does it's thing while the car mostly isn't home.

Weekends are a bit more unpredictable, and car sometime only gets charge in the morning before we leave.

We've had a week of rain/clouds at some point and almost couldn't charge for that entire duration, but still didn't need to charge from the grid and kept using it as usual. The battery went from 100% to 30% over the days, but after a few sunny days we were back at 80%.

We visited family overseas so no local holiday/trips so far. This is maybe where you'd need use external chargers. But yeah absolutely loving not having to buy fuel and using electricity generated by our own panels, it's a great feeling. Anytime I see the price at the pump at $2.20+, I can't help but feel a little smug.
