Then yes I'd agree with you, it doesn't make sense to describe your EV charging as costing $0.09/kWh since you're presumably only on the slightly more expensive ToD plan due to the EV.

Personally I'd love to have a ToD plan, especially with the rate structure you've laid out - break even seems to be using less than 1/3 of your daily electricity usage during the on-peak hours, which is only 1/6 of the day? I've got a bunch of fixed loads (computers) plus ones that tend to run overnight anyway (dishwasher, dryer, etc).

FWIW I'd think the pricing of the ToD plan versus the fixed rate plan has more to do with how the power company themselves has to buy power and model/hedge against demand at various parts of the day, rather than simply trying to make the costs even for the consumer.
