No, the cheapest I have found is £595.
Charging between 20% and 80% optimises the longevity and well being of the battery and is all you need for commuter runs. For a road trip you would charge to 100%. 7kw is the maximum you can get from a single phase supply i.e. most home situations (you can save £600 and charge from a 3-pin normal socket, and though it can take 24 hours to fully charge the battery you might replenish what was used on a commuter run overnight). 11kw needs a 3 phase supply and is what you would find in a commercial charging station.
