We bought our MGS5 a month ago and have done 2000km.
We just plug it in to a standard power point when it's parked at home.
We have solar on the roof, and when it's charging at night Tassie uses hydro power.
That 2000km represents about 3 tank fulls of diesel in our previous car, or about 165 litres (at current price around $430).
For comparison the EV gets around 16kW/100k so 320kW. Even if we weren't using solar and paying full price (23c/kWh), that's about $74 for the same range. (If my calculations are correct!)
