Actually, there isn't any problem with that charger at all. It's lying there idle for most of the time, just waiting for someone - anyone - to make use of it. (Checks ZapMaps - yes indeed, it's free right now.) If I actually see someone using it when I pass I'm mildly surprised. I suspect most of the people using it are either locals, or people visiting locally. I spoke to one man who was using it who had come from Denmark and was returning to Denmark, staying locally in the village. A couple came from Northumberland to our church one Sunday for a special event, and charged their car during the service. A couple of people who live nearby have houses where they simply can't install wall boxes and rely on it completely for their charging, and they're not on it all the time (or complaining about not being able to access it) either.
The issue that the visitors spoke about was the time limit on charging, meaning that in one case he had to visit twice to get his big battery filled up to start the return journey (you only get 45-55 minutes, and no return for another 90 minutes), and in the other that they had to sneak out of church to get the car off the charger, or risk a fine. In neither instance was anyone else waiting to go on it, nor had they had to wait to get on it in the first place.
This is a ridiculous conversation. People manage their finances in different ways. In my case I had an urgent need to replace my car, when I wasn't planning on doing that until next year, but a BMW came out of a side road in Glasgow and wrote off my Golf. This happened to coincide with a £3,000+ bill for an unexpected central heating repair. The planned move to an electric car had to be done at a time when I wasn't entirely prepared for it. I'm currently juggling a credit card I had to max out to pay for the car before the insurance money for the Golf showed up, so as not to put too big a hole in my finite savings. The expense of a wall box, right now, is something I need like a hole in the head.
I might decide to put one in in six months or so, I don't know. It depends on whether it turns out that I need it or not. The granny charger is mostly coping with my needs, and having the 50KW charger five minutes away is the icing on the cake. Yes I could have managed without it yesterday, because the granny would have given me enough and to spare for today, I'm hardly going anywhere tomorrow, and I'd have caught up to full by Monday at the latest. But since the charger is there, and nobody else appeared to be going near it, why not?
If the charger gets busy, whether because of villagers or visitors, maybe the council will install a second one. Or maybe it will be enough of an annoyance for me to decide to find the money for a wall box. But right now this is a non-issue. We are actually entirely well served by this one charger, and nobody is complaining about it.
