I think you're half right...Unless you have a separate meter for just the car I can't see how that would work for somebody just Sunbelt state that uses air conditioning during Peak periods of the day. 24 cents per kilowatt-hour is outrageous just to save money charging the car in the middle of the night.
Here in Florida are air-conditioning runs almost non-stop during the day which would be at the highest rate. It runs very little during the lowest rate period and it is by far the majority of our usage.
I switched to this from the basic/standard non-TOU plan. Removing the BEV from the equation, then yes this is a more expensive option based on my historical usage.
I ran my actual numbers across all of SRP's price plans (yes I wrote a program for this haha). I don't recall the numbers right now but the EV plan was maybe a few hundred dollars higher per year without the vehicle and a few hundred lower with it.
So another way to look at it is that my refueling costs are more than six cents per hour due to opportunity cost of being on this plan versus a different one.
Since I'm on a TOU plan now I'm also inclined to change some habits, such as waiting until 8pm to cool the house down a bit more. It's hard for me to put this in my data model since this isn't a choice I made in they past.
I live in a typical suburban house, somewhere between 1200-2000 sq ft (which is the typical range here). There is a single, 5 ton "12 SEER" HVAC system from 20 years ago, running maybe 8-10 hours on the worst days. I think the Mustang uses more energy to refuel than the AC to keep the house livable.
Anyway, interesting stuff to think about. You may be able to call FPL to ask what your cost would be on various plans based on your historical usage. SRP has that info for its customers. I didn't know that when I wrote my own program, but eventually I called and their what-if numbers were within a dollar of mine.
