Per a request from Gary I am posting an xGauge that is supposed to provide the status of rebalancing. This is still a work in progress. So far I have only observed displays showing 0000 and 0001. From my observations the 0001 does seem to indicate that rebalancing is in progress but I am reserving judgement over these results to see if these displays actually make any sense.
battery re-balance state
With RXD aabb where bb=08 indicates one byte of data returned.
The RXF of 1 in the 5th position indicates the data should return a Hex number.
This table shows what the display should mean for the BAL xgauge:
01 Rebalance in progress
02 Rebalance completed successfully
03 Rebalance aborted - battery fault
04 Rebalance initializing
05 Rebalance aborted by vehicle
06 Rebalance aborted upon request
07 Rebalance aborted due to battery temp out of range
08 Rebalance can't be started due to battery fault
09 Rebalance can't be started - vehicle did not allow
0A Rebalance can't be started due to battery temp out of range
0B Rebalance suspended
0C Rebalance can't be started - maintenance mode in progress
0D Rebalance can't be started - too many attempts
0E Rebalance aborted - tester no longer present
Currently I am assuming that the 0000 indicate that no rebalance has recently occurred. After battery discharged and while driving in Hybrid I saw BAL change to 0001. At least I know this xgauge is doing something.
I have also seen the 0001 after receiving the HVB message from MyFordMobile and the light ring around the charge plug was on for an extended period of time. Also my level 2 charger indicated that charging was still in progress.
At this time I can make no promises about the validity of this gauge. So any additional testing and input would be greatly appreciated. If anyone has questions I will do my best to provide an answer.
