Only you can decide if you want an EV enough to make it work @mitch. The problem with asking on this forum is that there is a disproportionately high number of EV enthusiasts (in comparison to the general population), so many people will tell you that it’s possible. On the flip side, there will be a few others (like me) who will say that we wouldn’t even remotely consider an EV unless we could charge at home.
Without repeating all the reasons why I wouldn’t entertain an EV if I couldn’t charge at home, the only relevant experience that I can give you is my nephew. Like you, he convinced himself that he wanted an EV and decided that he could make it work using public chargers (he cannot charge at home). At first he coped OK. He found a charger near a pub for (relatively) local charging. After six months the novelty had well and truly worn off and he started to find it a pain in the a*se. He deeply regrets getting an EV and cannot wait for the lease to end so that he can go back to a petrol car (or self charging hybrid). Admittedly that’s just one persons experience, but he’s a young man in perfect health, not an older disabled person, for whom there would be added complexity.
I don’t know how the costs would work out (public charging an EV versus say a self charging hybrid) but relying on Dobbies may sound doable, but what happens if you get there and the charger(s) are already in use or out of action? Is there a convenient plan B?
