 My knowledge of the world of electric vehicles is rather scant, hence the topic.

For those who have no access to off street parking, can these charging facilities be used with the correct equipment and charge cards for charging leisure batteries as and when necessary? Some windies just don't do enough daily mileage to fully recharge their auxillary leisure battery.

Also, if left overnight, could they provide 230 volt heating using a small oil filled radiator.

Or would another solution be a 230v electric element in the tank to heat the water sufficiently for several hours to be a heat source to keep the internals from freezing overnight.

There appears to be different types of plugs as well as 230v and DC charging. So I'm guessing we could use a fixed 230v to 12v battery charger through an rdc protected consumer unit that would also cover the power point for the frost heater or electric element.
