I loss another battery capacity bar

Sun Jul 01, 2012 4:08 am

I have now loss 2 battery capacity bars in 45 days..Back in May I had 12 bars and passed the battery test at Nissan with perfect 5 stars ...I have never had a fast charge ,the car is garage kept and I avg. 6/MKW and very little AC usage..

This is not going to be good for Leaf sales,at least not in Phx. AZ..

If I had to do it over again,I would of bought another Prius,I have never had any problems with that car in PHX AZ and I put over a 100,000 in 5 years of use...

Sorry Im just a little bit angry right now thinking about a $41000 car with 16000 miles on it that may lose a 3rd capacity bar or even a 4th bar this summer..

at 3 bars the battery will be at 70% remaining capacity and officially worn out.. lets hope Nissan takes care of you. How long is your daily commute?

Sorry for what? You have a right to be mad. I just recently look at 2002 TOYOTA RAV4EV that was for sale here 104K
104,000 miles, Original battery pack with >95% remaining capacity. 95 to 100 mile range.
Mine thinking is how in the world car that is 10 years old have better range as well as battery capacity. I am not battery expert and I do not believe I should be, but, me and those thousands and thousands that should be buying Smyrna production thinking what is going on where is the progress here?
If Li battery was not ready for prime why RAV4 type was not used?
Looks like we had such a bright future for this car. Leaf in our eyes was the car that will be changing the way all will commute. Wonder how many still believe that sale will reach 20K in USA this year. To me, like some saying, everything is great, seems strange. I still want Leaf to be next great thing and believe it can be, but doing nothing at this point and saying all is "normal" is equal to: we are completely fine with with sale of few hundreds per months, we are Ok with many Leafs that being offered as used cars with 1 or 2 battery bars already gone. Is the vision: Leaf is the future of transportation already gone, and we are OK with that?

Have you Tested actual range loss?
2011 Nissan Leaf sold after 33,000 miles
2012 Chevy Volt sold after 28,000 miles
2013 Toyota Rav4 EV 11,000 miles and counting!

Mark, sorry to hear this. It has occurred to me that Nissan may have viewed the single bar droppers to not have a "ripe" complaint, since their statement is that owners who follow the charging advice in the manual can expect to have 80% capacity after 5 years. So folks who lost 15% still had 5% capacity to lose, and four years to lose it in. (I know, to all of us it seems incredible that it could actually work out that way, but I'm trying to find an explanation for Nissan's silence.)

Now that you have less than 80% (according to their information as to what the loss of 2 bars means) and 5 years has not elapsed, your complaint is definitely "ripe."

I have contacted Nissan thru the customer service line, but I haven't pushed too hard since I haven't lost the second bar. Once that happens (probably this month), I will pursue my complaint a bit more vigorously.

I don't know if this has been discussed before. I'm curious if anyone has been able to determine if it is just a few cells in the pack that are losing capacity, or all of them. After all, if I understand the battery pack correctly, it could be compared to a chain and the weakest link in the chain determines the chain's total strength.

Yes, this is what I am waiting to hear: what an actual diagnosis reveals after pulling one of these packs in a service bay. It might be that a sensor is faulty because of the high heat and giving a misleading readout on the capacity gauge. Or maybe only a couple of "cooked" cells at the front of the pack are causing the problem, easily and much more cheaply replaced under warranty. We just don't know. Nissan should crack open one of the packs that has lost two bars and find the definitive answer.

I wonder about a few specifics:

  • Do all 10 of the charge bars still light up when charging to 80%? Do all 12 when charging to 100%? Or does the charging stop when the charge bars match the limit of the capacity bars?
  • Similarly, has your range, in fact, been affected? In the past, with all 12 capacity bars lit, did a typical 80% charge give you, say, 75 miles on your usual daily commute? But now you are only getting around 60 miles?
  • How about a 100% charge? Could you get, say, 90 miles previously, but now can only go about 70?

that would be true since BMS is working with total pack voltage for one parameter and when load is applied, weaker cell voltage drop will be much higher than a good cell.

No, all 12 (or 10 at 80%) bars are always used. They represent the percent of available charge.

Although I've read of more than one person whose first symptom is getting 9 bars on an 80% charge. At first it is once in awhile, but then it gets more frequent. A few weeks of that consistently and then they lose the 12th capacity bar...
