July on our SV+ per nissan connect:

4.4 miles per kWh. 299 miles

We put something over 1000 miles on our S+ with multiple 200 mile day trips. Not sure what overall efficiency was, but would guess upper 4s given amount of freeway driving.
I am somewhat surprised you don't record your driving stats. The trip computer makes it easy.

Based on daily trip computer info

Miles driven; 1551.5@ 4.8 miles/kwh

Other news; adjustment #3 is in the books and that drops me to 6% loss so far. This is actually a worse pace than my 40 kwh which lost 3.6% on same mileage, or 4.94% if matching time.

But its partially coincidence as the 2018 had an adjustment 5 weeks later that increased its loss to 6.61% so probably about the same rate.

One thing to note; I lost .69 % in the next 11, 000 miles before trading up.

2500 miles, wow. That is an active month.

Dave, it does sounds like the degradation curve is the same. Almost...algorithmic. That might also explain why my S+ after sitting on the lot for 8-9 months was only down to 98.5% as total miles was less than 10 miles on the odometer until we bought it. By now, it should have had 3 adjustments, yet feels like only 1. (Dec, Mar, June)


I charged my SV+ with 8800 miles to 100% this morning (94.36% SoH). Total GOM was 267 (it didn't fully balance, so might have gained 1 more) on normal driving. I sometimes forget the EPA is only 215. Whole I rarely fully charge the car, there is a certain satisfaction in having over 200 on the GOM.

That is the reason I upgraded to the Plus. Still very reasonably priced and yeah, I got a deal but even after losing 20% I will still have 200 miles of range and I expect this car will do the same as most are doing. Rapid loss of 7-8% then it slows way down. We shall see but I think this car will fit my needs longer than my desire to keep it. But I am certain it will at least be paid off when that time comes

I saw on Facebook someone was offering a CAN bridge device which would let you aise the top end voltage in a Leaf something like 4.12 to 4.2v. Supposedly it ups range about 8%. I have heard rumors that some of Teslas "optimizations" included voltage changes as well.

Do you think its safe?

Not if you want to keep your battery warranty intact and minimize battery deterioration. I doubt that it applies to the 62 kWh battery because mine already charges to about 402.25 volts (402.25/96=4.19 volts per cell). Even if you could raise the volts/cell even higher, it would not increase actual range significantly because I don't see much useable range difference when I stop charging a bit early (as long as car is in charge taper/cell balance mode).

4.2 volts is the maximum voltage for most lithium cells. There are bicycle BMS units with the 4.2V setting, and the packs don't last as long as those set to less than 100% actual SOC.

Safe? DK, but smart? definitely not. Your gain in range isn't worth the accelerated degradation. There IS proof that high voltage increases the rate of degradation.

The range is enough in a plus I can't see it being worth it any way I look at it, same for the 40kw.
