Surely the only viable way forward with public charging is for the govenment to insist that - where they have space to do so - all petrol stations should have at least four charge points that are always reliably maintained, fully operational and govenment subsidised for price. EV punters could then feel safe to charge day or night and to the benifit of the station spend half an hour consuming Costa, or scoffing M&S wraps. Although the govenment should also insist that petrol stations improve their toilet facilities too, to make the prospect of an half hour stop more inviting.
The bit I still don't understand regarding in particular the PHEV, is that everybody (including Mitsubishi) says not to use 30min charge points 'too often' (whatever that may mean) as this practice will deplete the life of the batteries. Does this 30min charge depletion problem apply to other makes of EV? What exactly is 'too often'. This is a horrible flaw in the concept of public PHEV charging. I think maybe it should be made very clear that home charging, and its associated installation costs and logistics, are the reality of Mitsubishi PHEV ownership. Don't know about other EVs. I suspect Tesla may have the resourses to be the exception, but I doubt I'll ever be wealthy enough to find out.
