Our utility has just rolled out a time-of-use rate plan. They've done it very very quietly (and were swearing up and down that there was no such thing coming as recently as a few weeks ago). They also don't publish the actual rates anywhere on their site (I had to dig around with in a filing with the state utility commission to actually get numbers). Weird.
Basically on their new scheme, I would pay 2x normal flat rate during peak hours of 2PM–6PM on weekdays, about 77% of normal rate during super off-peak of midnight to 6 AM, and about 89% of normal rate any other time. Seems like this would be a good time to get going with it, since we've basically turned the our two AC units off until next spring. Next summer I'll have to figure out how to keep the house from getting too hot during those 4 hours of peak time, but I'll figure that out then.
So I've set our Wallbox schedule up so that charging starts at 12:01 AM. I was going to cut it off by 6, but then figured that we might want to be able to pre-condition the car while it's still hooked up.
One thing that I wish the Wallbox had was a hardware button on the unit to override the timer. Like for instance, if we came home and wanted to get some charge into the battery before going somewhere else later in the evening, it'd be nice to just have a physical button to hit to start the charging rather than having to futz around in the app.
I understand that if I want to schedule the charging, I will not be able to do it in the car or in the car app right now.
