Re: Lost a "high-voltage battery status" bar, down to 11

Interestingly enough, in the video above it talkes about "power loss" waranty, not capacity per se. Nissan apparently DOES NOT cover loss of capacity to 80% at all ( as I thought it did). That is considered normal according to the rep in the video.

Now, loss of power...how do you quantify that?! "It's not moving as a jack rabbit anymore?" Is that it? I wonder... Pretty crafty, Nissan.

Personally, I hope to replace that battery anyway in about 6-7 years with a double density product, delivering at least 200 miles range. Lithium air, baby (by IBM).

I'm thinking I should take it in to the dealer for some documentation even if they turn me away initially.
Yes, I would, in your situation.

I don't intend to be critical, but given your location, if heat and time spent at 100% charge are the greatest variables in loss of capacity, Your 12th bar, could perhaps, be just be the first "canary" to stop signing.

Please report back, when you find out more, about how much range and kWh capacity that bar corresponds to.

the "topping off" is not that bad if you drive it right away. sitting at 100% for a month is definitely not good.

as far as heading to the dealership, i would most definitely do that. get copies of any info they give if (if possible) very anxious to hear how they respond to your situation

Can you meet somebody in Phoenix with an SOC-Meter and see
what reading you get after an 80% charge, and after a 100% charge?

This is very interesting driving data. I suspect you'll end up wishing you had paid more attention to (high) battery SOC than (low) tire pressure.

Permanent loss of power should be easy to see on the dashboard, you should lose one of the "power circles" (to the right of the regen circles).

But this "topping off" category means they didn't drive the battery down to 80% before topping up, which means the battery stays at >80% for the entire charge-drive-charge cycle.

I'll see what I can do.

In regards to the video, I find it very scary. I'm not sure what 'power loss' is supposed to be. So, I don't lose power but my range is 30 miles at some point and that would not be covered? I don't think that will fly.

You are the first on-forum report of a Loss of a Capacity Bar, I believe.

Down 15% is ... disturbing to see it happen after just 14 months,
but you MIGHT have started with a low-capacity battery?

It looks like having access to an SOC-Meter, even before purchase,
would be a handy thing for us all.

One post earlier stated that the dealer said their LEAF was "down 2%"
in capacity.

That is first report that a dealer was able to measure the Capacity.
Of course, I could have been just "imaginary" information.

Can anybody verify that a dealer can "see" the Capacity percentage
with their Consult III+ machine, and how to ask for that test?
