Does the HV Battery Really Run 80%/20% ?

Thanks. If that info is correct, then the Insight plus a grid charger should be in the ballpark of a PHEV-3. Of course, the motor would take at least 3.6 minutes at full power to burn through that much energy; I doubt in real-world driving you could burn it off faster than 6 miles or so, and probably more like 9-10.

Okay, sorry for the distraction.

Regarding the "*uhtrinity" positive recal, I just found out some more information using the following scenario:

1) After topping off battery, it is purposely drained it to/from work to exercise it

2) After getting the battery down to about 145 volts after getting home it is again trickle charged using the Dabrowski grid charger

3) Without pulling fuse #4, if the voltage is within 165 volts from being topped off, turning on the ignition key and waiting 2 minutes will automatically cause a positive recal

If on the other hand the #4 fuse is pulled to reset the BCM, the voltage needed for a positive recal is about 169 or so. Don't know why the difference, but that is what I measured thus far.

* A uhtrinity recal is one where starting the gas engine to cause the positive recal is NOT needed. Simply get the battery voltage high enough from trickle charging, turn on the ignition key to display the dash, and simply wait two minutes for the recal. If it does not occur then the battery voltage is still too low.

I believe there is a difference in the old bcm vs the new ones. The old one allows a positive recal at 168 volts or higher without starting the car. The new version expects the car to be started to do a recal. My car has the old version, a friend has the new version with paralleled packs and charger, but has to start the car to get a recal. And btw, the keyon recal was discovered long before I purchased my car :P
