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

Sun Jun 24, 2012 3:17 pm

Is the lost bar the one labelled #13 or #14 here?: http://www.mynissanleaf.com/viewtopic.p ... &start=450" onclick="window.open(this.href);return false;

Its the capacity bar (14)

In response to a question:

The car is garaged. It is rarely out of the garage for more than 2-3 hrs at a time.
Its primarily used to pick up and drop of our son at school, trips to the grocery store
etc. Our garage door is insulated and today for example its 102F outside
and 85F in the garage.

As much I want to protect my car from fast battery degradation and be an example that Leaf is the way to go. I really can't find anything more that can be done by ravi to avoid rapid battery degradation. He charged to 80% most of the time, never QC, never exposed car to direct sun during hot weather, kept car in garage in very comfortable temp. Wonder what else can be possibly done by owner to slow down battery degradation?

I agree, this is very worrysome since 85° F is not a high temperature IMO.

Might be interesting to get a thermometer and check the "usual suspects".

I.e. -- do you (occasionally) park your car outside in the driveway? Does the driveway catch a lot of afternoon sun (sloped to the west)?

I live in your area and can think of a couple times I have been astounded by the heat. Once was while working on a car on a west sloping driveway with a 3 story building to the east also reflecting heat I presume -- apartment complex with very little air circulation, another time fabricating a gutter on a metal roof. I did not measure the temp on the roof but am quite sure it was well over 130 deg F (I could only work for about 30 minutes at a time and had to get off). I did measure the temp above the driveway (a/c thermometer placed about 12" above concrete). I can't remember the exact temp but I do recall it was well above (+20 deg f?) the reported (weather service) ambient.

Can we start a list like this people in hot climates that have similar usage stats (i.e. age/mileage) that have NOT lost capacity yet?
Just to get feeling for the x in 20 out of x.
I suspect it is a systematic thing, i.e. a consequence of the heat acting on the battery chemistry, but maybe not (...wishful thinking...)

I think a more useful list would be to record for as many people as possible:

--Gid count at 100% charge
--Length of ownership
--Odometer mileage
--Geographic location

This would include everyone we can get a measurement for, whether they have lost a capacity bar or not.

Once LEAFScan is deployed an automated reporting of a normalized stat like this will be amazing.
