I installed a scangauge in my FFH and I can't get it to read SOC of the battery. I had this exact scangauge on my FEH and loved having the SOC data.

Anyone have any ideas?

 

Why do you need it? The HVB charge dash display is a very high resolution graphic. The top of the "L" is probably 30% and the bottom of the "H" is probably 80%. A re-equalization event goes over the top of the "H". I had a recent equalization event at 22k miles. After that, I was able to drive 4 miles in EV. The capacity of the FFH HVB is about 1.4 KW hrs. If the equalization charged to 100%, I then used 70% or 980 W hrs. to the 30 % level in the 4 miles. That comes to about 245 W hrs. per mile. That's about right as the Prius is about 200 W hrs. per mile and gets 20 % better mpgs.
