OK thanks. What do you mean about EV subsidies schemes and batteries?
Also, if I went for the Octopus Go and only charged between the off-peak times, am I right in thinking that it would cost £4.50 to charge the I-Pace from empty to full? 90kwh battery x £0.05/kWh = £4.50?
Or is my maths wrong? Or maybe there are efficiency losses? I just wondered, roughly, how much it would cost to charge the I-Pace fully if only using the off-peak energy?
Octopus Go is £0.15p Kwh peak rate and £0.05p Kwh between the hours of 00:30 and 04:30, I tend to just charge my car between those hours, so cost is ca.£1.40 ish for the four hours, I get ca.36% charge in that time. If I charge for any length of time during the day, it costs ca.£1.05p Kwh, but its rare I need to do that and even rarer that I ever arrive home at 0% SOC, so have never had to do a 0% - 100% charge at home, or anywhere else for that matter.
PS I also looked at the Agile tariff, but the peak rates were a lot higher than Go, so it meant over all I would have been worse off. I actually did some calcs using a years data that Octopus provided and it was a much better deal for me to be on Octopus Go, but of course your situation might be different.
PPS you would not be able to charge from 0% to 100% within that 4 hour time frame at home, you would either have to do some charging at peak rates or charge over 2 / 3 nights at cheap rate. TBH, the cost of charging at peak rates is not that much anyway and is far cheaper than filling up an ICE vehicle.
PPPS I drove 340 miles this weekend, cost me about £4.00 to charge it at home to 100% then the next two partial charges I did were both free.
