Re: Less than one day until Carvana brings a Leaf

Tue Jun 13, 2017 8:35 am

I am still an ignorant noob, so I will just ask: does anyone else think that the fairly high max-min cell voltage range and the three or four exceptionally low cells is a bad sign, or is that OK?

I always feel happier when I see that my pack has balanced itself to about 10 mV or less, but I don't know if that is really important. Mine looked like that (17 mV) on Saturday after I ran it down to VLBW, but after a 100% charge and a short, sharp drive it was back to 9 mV.

On the other screens, how many GIDs is it showing at that SOC, and what is the % GIDs?

Coincidentally, I just pulled my car (2013 SV, 39,158 miles) off the L2 charger at work 15 minutes ago and LeafSpy is showing SOC 95.2% (up from 61% after 65-70 minutes on the tap). Other numbers showing now are 237 GIDs, 84.3% GIDs, 72.1 miles to LBW at 5.1 miles/kWh, AHr = 55.96, SOH = 85%, Hx = 83.24, min/max = 9 mV, all but 7 cells are in 3 bins on the voltage histogram, mean battery sensor temp = 62.5°. Make of that what you will, because I don't really know what it means!

Edit: more info for your comparison: my car was born in July 2013, grew up in San Jose CA, and graduated from there to an auction in December 2016. I got it two weeks ago.

If you say "no" to this deal, do you have to eat the sales tax?

I still worry about what it'll be like in winter. If you only get 2.5 miles per kwh, you've only got about 42 miles to 5%. So in the case of a blizzard you might get stuck. Do you have another car you can take when weather is really bad? If so, I think you'll probably be alright when the weather is mild for a while but I'd still recommend checking plugshare for any chargers along your route in case things end up looking bad one day.

I do have an old CR-V I plan on using when there is snow on the ground. I could use it for non-snow frigid weather. At what cold outdoor starting temp would it start to be a problem?

I am holding off installing a permanent EVSE at work since I rent the space. Can I use EVSE upgrade? I think that is what it is called and plug that into a 240V at work?

Thanks

Gentlemen, I think the time for worrying about your battery has been long overplayed.... Before, I tried to nicely suggest that you stop worrying. I am joining another topic because this is too much...

Having the old CR-V as backup though the first winter seems reassuring. I guess if you're not keeping it forever, that might someday be a problem.

You can see a graph in this thread that may be of interest:
viewtopic.php?f=6&t=24073
There are A LOT caveats and arguments about that graph, so be sure to read the whole thread. When not crunching through snow, it seems maybe the "average" Leaf can go 50 miles in cold weather. Whether you can do that is another question.

If I were you, when it starts to get cold, I would dress REALLY warmly and do the trip with no heat. If (let's be optimistic and say "when") you get home with plenty of range left, try driving with some heat the next day for just part of the trip and sneak up on using heat the whole way.

Can you tap on the Summary screen three times where it now says 376.2V etc and get that to change to the Trip info? Seeing your current trip mileage and consumption might let someone with a similar trip and climate answer your question with more confidence.

BTW, it looks like your battery holds only 10 GIDs less than mine, if that.

You should be fine in the winter as long as you preheat while plugged in at home in the morning and keep the temperature setting low on the way home (use seat and steering wheel heaters). If you can plug in L1 at work, you have no worries. EVSE Upgrade is an excellent option if you have a 240- or 208-volt outlet at work. Tell me the type of outlet you have if you want more recommendations for charging at work.

Edited to add: Check your tire pressures. Pressures less than 40 psi will cause increased tire wear and reduce range. I run at least 44 psi cold. Your Leaf Spy screen shots show 3 tires low and 1 that may be high.
