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

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.
