Sudden decrease in Ideal Mileage

So a 2010 2.5 Sport, mostly a Sunday Driver. Typically see ideal mileage of around 170 - 175 range. In the past month, the ideal has dropped to 82! The charge bar looks like half charged, so it appears to just need a charge. Range mode bumps it up a bit, not much. CAC shows 142. Any ideas?
 
I can't remember the last time I looked at the CAC, so I don't know if it has declined too. Attached is a photo of the ESS SOC, is there a log that shows the CAC values?

Looks like one or more bad bricks pulling things down. The charge stops when SOC MAX hits the limit, but your displayed SOC / range is limited by SOC MIN.

If you grab the logs, you can have a look at the text file with brick voltages. Should be able to see if it is one or more that are off from the others.

It could also be a bad voltage reading from the BMB, but much more likely to be the brick itself.

Regards, Mark.
