You will still have cool to cold nights, right? That should allow the pack to cool off every night.
johnbechtold said:My 2013 Leaf SL still charges up to full bars, But the battery only holds 16kW! I'm wondering if they've reprogrammed the system so the bars just don't go away, because mine should be missing 4 bars. I know this because I also have a 2015 that I bought new, and I am very familiar with the way the 24kW battery performs. For example, from a near zero charge state, a full charge takes just under 16kW, which makes perfect sense because I get a little over 4 Mi/kW, so 4 X 16 = 62, which is very close to the actual range of the car.
So how do you get it warranteed if the capacity drops to half, but no bars are missing????!!!!???? I want to go more that 60 miles on a full charge!!
Anybody else experiencing this with the 2013? I've seen other leafs with bars lost, but I've never heard of dropping capacity with no bar loss!
John- 1015 Leaf LV bought new in January 2016 currently maintaining full capacity and range at 23,500 miles...(No Fast Charger), and a
2013 Leaf SL with 30,500 miles and a capacity of 16kW, and 58-60 miles, and the Quick Charge system, with no bars missing.

I live in San Diego so it doesn't get too cold in the winter and run the hell out of it for the warranty but am afraid to kill the battery after the warranty period. I tried to call nissan's leaf line and they indicate you are **** out of luck if you don't get that 4th bar lost. No assistance on battery from my calls.
Thanks for any suggestions you can provide.
Thanks,

The only known substantial factor aside from heat and time is HIGH SOC. Parking the car with a full charge whenever possible and leaving it sitting that way might work, but it also might not work in time.
Is this measured or calculated ?johnbechtold said:For example, from a near zero charge state, a full charge takes just under 16kW,
Yes on the first and from where is it being measured or displayed?SageBrush said:Is this measured or calculated ?johnbechtold said:For example, from a near zero charge state, a full charge takes just under 16kW,

One thing is for sure, you will engender more confidence in your understanding of the car if you get your units sorted out:
kW is a power
kWh is an energy amount

Since we're now entering winter, you won't have heat to help you with this one. I suggest parking the car at VLBW for long periods of time. Anything under 5% should do. Maybe charge just enough for your day's needs? You'll suffer range anxiety every day until the SOH drops below 68% though. Not a good way to live frankly.

Really?!
Although anecdotal, my most significant SOH drop came after I got home under VLBW and plugged in, but didn't change the charge timer, so the car sat at VLBW for almost 8 hrs.
OP, I suggest you try it just for the weekend and check your leaf spy stats.

Oils4AsphaultOnly said:LeftieBiker said:Did you check the SOH before or after recharging, and did it go back up later?
As I wasn't expecting to lose SOH that time, I measured it afterwards and saw a 2% overnight drop in SOH. After a few days of rebalancing the pack, I got 1% back, but not the full 2%. I never left the car parked overnight below 20% ever again.

This goes against what is known about lithium batteries. If you had driven it to Turtle and left it there, I could see damage occurring. But what you did shouldn't have caused a lasting drop in capacity. My guess is that it's an artifact of the BMS, but I really can't say for sure. The OP could try it, but all bets are off...

Do you have updated LEAF Spy stats? Your pack is not following the curve of others in your build time frame AND you live in a pretty warm area
