Re: My Car is Only Charging Up to 12 Bars

Fri Mar 31, 2017 10:24 am

Howdy CB,

In my case i've had that happen and it was due to a weak starting (aka auxillary) battery--the 12V lead acid.

The other issue of which i've heard is the subject of the recall of the motor control unit (MCU), namely a degradation of the insulation within the unit. Considering your humid and salty environment it may be that corrosion or deposits may be causing a similar effect.

You may want to start a new thread for your issue.

I've been driving around with my new battery for a few months now and have noticed about 20% increase in range(compared to new). Before I had the warranty replacement my SoC degraded rapidly. The last time I took it to the dealer I could only get 3 bars. Those were my magic words though.. "unable to charge fully" and that triggered warranty action. Happy!

Boy, that was quick! Have you done a EVBatMon capacity measurement on your brand-new battery?

Yes, 2 weeks and a day was pretty quick. Oakland Mitsubishi was great! I have to thank those guys. They received the battery sometime last week and started the change out Friday morning. By Monday they were finishing the job and making sure that it charged, etc with Monday being the two week point. I picked it up the next day on Tuesday. What I think really helped here is that the mechanic doing the job owns and drives an I-miev himself though I didn't get to really talk to him (yet). I really lucked out here! :D

That's a good idea about checking EVBatMon. What is the best Ahr reading out there? I'll try to do this tonight.

I'd like to hear what the readings are - I haven't gotten the EvBattMon yet - sounds like maybe I should...

Well okaaaay, 35Ah. :?

I haven't given it a full charge yet. Maybe that has something to do with it? I'll charge it up tonight and try again tomorrow. 8-)

Do a calibration charge on level 1, and that should shoot up into the mid-40's. No way a new pack has that little capacity.

Ed, I think it may be a residual reading from your old pack. As PV1 said, give it a nice long slow recharge from under two bars, but don't be surprised if it doesn't recalibrate right away. I would be inclined to take a reading every day for a few weeks (and be sure to write down the data). Do let us know what happens.
