Electric Highway (Ecotricity) has a high rate of broken chargers. When you find one, they seem to charge a minimum fee of £12 regardless of how much you use.
Most chargers are slow. Either 7kw or 11kw is common; 20kw is considered rapid in some places.
The fragmentation of networks means you need at least four crap apps just to get around and then you’ll probably need to install a new app if you’re going somewhere new.
What you call convenient locations are a mixed blessing. Spaces for chargers are often ICEd in my experience because they’re in busy car parks.
I just want to pull up, plug in, and tap my credit card. The charge networks seem to go out of their way to make using the service painful.
That's exactly the way that all Polar rapid chargers work, and there's a lot of them scattered around now. The rate is lower if you join as a member though.
