My battery charge guage is stuck at 3 bars... I drove home charging for 6 miles last night and it stayed at 3 bars the entire time... once I got near my house I have a long stretch of a little over a mile, I was abled to use FULL assist for an entire mile...

Still 3 bars :?

Any ideas what is going on here? Even if the guage was having issues it shouldn't give me full assist for a mile :/ I think it is still charging and assisting but is somehow unable to monitor it.

It sounds like maybe the BCM, or one/some of it's sensors...
Any thoughts?

it could be ok, I had the same thing happen on a fast drive to my parents house where it would charge and assist, but the guage didn't change. it didn't reset on me but on my way home I went down a very big hill for several miles to charge it up and I and managed to snap it back into more realistic display.

if you've got a big hill near you it might be worth the trip! I know I appreciated it just for the peace of mind.

Reads like its time for the IMA reset proceedure.

Disconnect the 12v battery for about 1 min before leaving for an errand (save the gas at idle to recharge the IMA pack by combining both with a useful trip). Then leave and expect a forced charge for the first few minutes of driving.

Or use the preferred proceedure:
(disconnecting the 12v battery can be hazardous without knowledgable precautions)

But for such to occur for only a day or so it is a bit premature to begin to "worry". The SoC level varies for many different reasons. Remember, the display is a _calculated_ value. Until its _stays_ "stuck" for several days there may not be a "problem". The MCM and or BCM can "glitch" resulting in the IMA getting stuck in the SoC doldrums for many days at a time.

The reset proceedure corrects this similarly to restarting your home computer. But it also "excercises" the batteries one more time. A _small_ (almost unmeasurable) additional "wear" factor occurs for each battery SoC cycle Empty :arrow: Full so repeated needless resets aren't the best in the long run.

HTH! :)

Gave up trying to figger it out

My go-bug drives me crazy trying to second guess the charging rhyme or reason. Sometimes it lays at the bottom for a day. Next morning, whoosh, full charge by the time I'm at work (40 minutes at about 50 average mph). Now I only worry when the thing does a self-imposed 'recal', which doesn't happen very often.

It can never keep a full charge for long around here, way too many hills.

Ah, well thanks... I've never had it act abnormally before. The charge is always predictable before...

When i made the above post it had been at 3 bars w/o moving for 230 miles, at 250 miles it dropped the harge to 1 bar then has recharged properly since. Just freaked me out to have it charging for 230 miles but not change the bars :p

Ah Ha :!: ;)

There are all types of "strange" and unusual SoC gauge readings. Most are _normal_. In general until a reasonably long term pattern emerges different SoC gauge readings should be thought of as normal, not the other way around. ;)

Its just knowing that there's the potential at almost any time for the IMA pack to crap out that makes us paranoid. ;)

If you haven't already, read this thread:
