Might be a strange question but... can you use the battery without putting miles on the car?
Problem solved!
Problem solved!
I wouldn't say it's "for no useful reason". By cycling the battery more this past week, my stats have increased 3%. I need as much usable capacity on the weekends as possible and lately I can really tell the difference compared to a few months ago.BrockWI said:This is just my 2 cents, but cycling the battery is using the battery, whether it is to run the heater or to move the car. I would advise against running the heater to use up battery power, your just adding cycles or "miles" to the battery for no useful reason.
As Tom T said, it is time and cycles that degrade a battery. I would add to that, leaving the battery at a high state of charge isn't the best for the battery as well. So if your not using the car that much just don't top it off when your done.
I find the biggest change I see in capacity or Hx is when I run the battery down pretty low, to LBW or VLBW. But honestly I don't think that "helps" the battery it just gives the car a better picture of the actual battery capacity and adjusts accordingly.
That is correct.BrockWI said:... I believe all your doing is updating your battery stats, your not actually increasing the capacity of the battery by doing this, your letting the car get a better estimate of what is in the battery and what the battery can do. ...
That is very cool! I'd do the same if I could.knightmb said:I use mine to ferry power from QC and dump it into my solar banks. It's like getting $2 every time because the QC is free and the nearest station is only 3 miles away. Helps to keep down the electric bills. :mrgreen:
I already drive pretty slow so I can't go much slower but I see your point.BrockWI said:I could be wrong, but I believe all your doing is updating your battery stats, your not actually increasing the capacity of the battery by doing this, your letting the car get a better estimate of what is in the battery and what the battery can do. I guess it might add a tiny bit of capacity by exercising it, but I would but it is less than .5 kWh or more likely .250 kWh, going 2 miles an hour slower will give you more than that over the a full charge.

TimLee said:Occasional deep cycling to VLBW or Turtle and then charging back to 100% will help the LEAF know available capacity and will help your available range a bit. But more cycling does increase long term capacity degradation some
Hey, I totally missed that topic somehow. I did the exact same thing (even have the same brand inverter, those rock!) but I just used 4 pronged 50 amp dryer outlet and reused the extra wires to double on the current to 100 amp so that I had a nice easy dryer plug for the inverter (was the cheapest and safest way I could do it), but the plug you have looks awesome!KillaWhat said:I'm not sure I'm on board with your plan, but I can sure solve your problem.

My inverter can power my fridge, or Christmas lights, or whatever, and discharge the HV pack very nicely.
Again, not sure your theory is sound (not sure its not either ) but this will do what you want.
Good luck.

In one week, by cycling more, I'm up 0.5 kWh. I will continue to cycle at least every 2 days, if not everyday, and see how much higher it will go. I will probably only try for another week and see where I'm at then determine if I'll go back to charging 2-3 times per week and see if it stabilizes or starts to go down again.
I'm charging the same way I normally charge but more frequently and stats are improving rather than continuing to go down or stabilize at the lowest ever.
Whatever the case is, I did not expect to be down 10%+ in 7 months and 4,500 miles and if I can gain some back, I will try.
Thanks for all your posts!
The SOH could definitely be wrong. I have no clue. I'm using the newest LeafSpy on iOS, v1.1.1 en. I literally just updated to 1.2.1 as of this post but haven't connected to the Leaf yet.dhanson865 said:wow i just took a serious look at that signature.
2015 Leaf Mfg: Jan. '15 // Pur: May '15
Best: 6/27/15 - 1,416 Miles - 292 GIDs - 63.11 Ahr - 22.6 kWh - 100% SOH - 97.2% Hx - 4 QC, 29 L2
Worst: 12/12/15 - 4,616 Miles - 259 GIDs - 55.02 Ahr - 20.1 kWh - 99% SOH - 82.8% Hx - 17 QC, 96 L2
I have to think that the SOH% is wrong or now a useless number on a 2015.
55.02 Ahr / 63.11 Ahr is 87% that's right on the edge of losing your first bar.
What leafspy app are you using? IOS vs android, and version of app.
I'd think we need to get a screenshot or debug trace log to be sure but your SOH% shouldn't be that high with your AHr that low.
That is very cool. I think it's above my head though but even if it wasn't, my garage where the Leaf is parked is detached and nothing in it to consume the power.KillaWhat said:I'm not sure I'm on board with your plan, but I can sure solve your problem.

I've tried to partially charge and only charge when I really needed it and my stats still continued to go down so I went back to charging to 100% and it still made no difference.hieronymous said:Hi LeafMuranoDriver
This works for me - hope it helps your problem.
