Having spent a few nights reading about the Mitsubishi Outlander PHEV, it's suggested that the BMS does just that. "Full" is 90% of theoretical charge.
I remember reading about the original Prius assigned "empty" to 60% charge or similar, which was appropriate for the chemistry at the time (NiMH?).
There seems to be a fine balance in the factory designs: "Charge as much as possible to outdo the competition in range, but don't overdo it to result in 10,000's of warranty claims in 6 years time. I hope they got it right
