Hi Collie, you have a Škoda and Intelligent Octopus, so similar to how I would be.
As the cheap rate is only 6 hours and not continuous during these 6 hours, to get say 50 Kw some charging must take place outside of cheap hours.
So if you plug in at say 7 pm and ask for 50 Kw ready for 7 am, is it all charged at low 7p rate?
Regards, wonky
