Some interesting points there. Octopus does seem to be good for EV owners, one of my colleagues is on their agile tariff and charges his Tesla overnight at home and also from his solar/home battery - although that's only about 10KW so only a going to put ~15% back into the Tesla battery?
But the investment in solar/battery was over £10k on the house. The Tesla cost more than a decent ICE car of equivalent size/spec, plus depreciates a lot faster. Just not sure it makes sense yet. I'm sure it will in the future... but who knows when the tipping point will be?
What will be interesting is when the vehicle-to-grid (VTG) and vehicle-to-house (VTH) technology becomes common place. The idea of charging your car at night when cheap, then using the car's battery to run your home appliances during the day instead of peak pricing per KWh sounds awesome. Electricity prices are determined by the demand at a particular time of day, so if you work from home and have the VTG tech, surely a car becomes a money-making asset? Charge it at night when cheap, sell the power back to the grid when the demand is high?
Will certainly be interesting to see where we are in 5-10 years...
