I'm actually on PG&E E-6, not EV-A, as I don't charge my EV enough to make it worthwhile to get the slight rate advantage in exchange for shifting the Peak period later. I forgot that EV-A has weekends as peak.
I agree that at least a one-day lookahead would be great.
I don't really see a lot of extra discharging during part-peak in practice. It helps that I have a little off-peak energy on Monday mornings that fills my Powerwalls back up after the Sunday part-peak discharge. That makes the Sunday discharge more sensible than it otherwise would be.
As to the SOC window: I agree that it doesn't matter which part you use. I would also prefer to err towards higher SOC in the winter. In the summer, having lower SOC during the week means there's a small arbitrage of the extra off-peak energy on the weekend.
