This chart shows you how risky (cell voltage reversal) it is to continue driving past VLBW, not something you want to do on a routine basis.
I very highly doubt it's risky if you are inferring that it might significantly damage a cell - in which case I ask you to stop spreading FUD as you are often inclined to do.Herm said:This chart shows you how risky (cell voltage reversal) it is to continue driving past VLBW, not something you want to do on a routine basis.
Here is a scatter plot of TickTock's Battery Voltage versus GIDs:RegGuheert said:TickTock has recorded voltages at a bunch of low GID values over time. They don't correspond to LBW or VLBW, but a plot of GIDs versus voltage might tell us something about how these are related, particularly if we could tag the temperature at each point.drees said:To my knowledge we don't have any data like this, but this would identify if the BMS is hiding any additional capacity at the bottom of the pack.

I'm quite positive you used to see "83%", not 80%, because 10/12 = 0.8333...DesertDenizen said:I have 12 bars but the telltale signs do not bode well. My 80% charge will sometimes fill only 9 bars, my GOM shows 75 miles after always showing 83 miles after a 80% charge. And on my computer when the charging ended it always showed an 80% SOC, now it stops charging and shows 75% charged.
Not saying that two signs is good , just that the "percentage" reported by the website is content-free and misleading. It tells you nothing more than what the bars there show, and it is not "SOC" by any stretch of the imagination.

Here is another cut at this chart. This time I have split the data into two sets: One set before April 15, 2012 and one set after. That gives us a kind of image of how things have changed as the temperatures got hotter in Phoenix:RegGuheert said:Here is a scatter plot of TickTock's Battery Voltage versus GIDs:

Clean the FUD from your eyes so you stop seeing it everywhere you look. At VLBW you are depending on your BMS to not glitch and allow a cell to go negative.. yes its risky, plus it abuses the cell for little gain.

Many people lost their 2nd bar shortly a month or two after they lost their 1st bar (myself included). So it's more likely that you'll lose your 2nd bar sooner rather than later.AZMerf said:How can I get my name on the first page of this thread?

I've now officially fallen victim to a 2nd bar loss today at 19,345 miles, almost 14 months into my ownership. My first bar loss was at 16.5K miles back in 5/28/2012, only 2 months ago. I've called Nissan and reported my 2nd bar loss today. I'm already on the Wiki list for 1st bar loss. I've asked Stoaty to add me to the Wiki list for my 2nd bar loss in the other thread.
I don't take the LEAF to work, so it doesn't sit baked in the sun all day at work. It sits in the garage during the day unless a family member takes it on trips around town.
JRP3 said:Highly unlikely, and that it would only damage packs in warm areas makes it even less likely.
