Won’t the majority of charging be done overnight? Purely guesswork here but I’d think that there is more energy being used by households through the day (cooker, washer, tumble dryer, kettle etc) than there would be with the same household charging an electric car overnight.
If the grid can meet the demand through the day, why wouldn’t it meet the demand through the night?
Because everyone will be charging overnight eventually- during the day a lot of houses are empty and need changes throughout the day
