Have 2 questions on this issue with Capacity Loss:
I am understanding correctly we could actually see a Battery Capacity bar being added back on? I.E. have 10 bars, but in winter may see 11 due to cooler weather?
Also, if I am using the 120V trickle charge when charging at my home(Waiting for EcoTality to install the 240V charger, will this damage the batteries?
Thanks All.
We don't have acces to the battery degradation data as reported by the car (edit: with the exception of the obvious missing capacity bars at 85%, 78%, 71%, etc). We will when
LEAFscan is released later this year.
There is a heat indexed limit to charging that we can only guess at the particulars.
Dave guessed 2-3%; I've observed almost 10% at over 136F degrees (battery temp) when measuring stored energy via the Gidmeter at a "full" charge. When my battery returned to 70F ambient temperature later that day, it returned to 99% stored energy when fully charged.
Clearly, we don't have detailed data in this area, however it's just not that hard to get. Heating the battery is easy with multiple QC, then measuring the Gid count at set temperatures of the battery at "full" charges. Let the battery cool to 70F, and measure again. It should have returned to its original Gid count.
Please don't directly confuse this "temperature related charging inhibitor protocol" with permanent loss of capacity as reported by the battery capacity gauge. You will not get that back.
