Re: Hx dropping constantly!

Good question. All I can offer are these stats:

At 9,305 miles I was at 60.11, 91%, 92.28% (AHr, SOH, Hx).
100% charge was showing 260 GIDS 20.2 kWh remaining

at 11,065 miles 66.65, 100%, 102.34
100% charge was showing 284 GIDS and 22.0 kWh remaining

I'm back in free fall state. On the way home I drove 8 miles and watched the Hx value fall from 98.91 to 98.17. The car is around 50% SOC. I'm going to charge at work tomorrow and see if the numbers will climb on the way home with pulse driving. Past experience says no, but it will be a good test.

Latest stats. After two pulsing sessions LeafSpy is reporting 66.86 AHr, 100% SOH and 104.18 Hx. My 14 SV is at 12,255 miles. It will, of course, start dropping over the next few weeks, but how long will the Leaf play this game? I have been as low as 91% SOH back in May before I started this experiment.

Better question is how long will you keep playing this game ;)

Stop worrying about it so much. The main things to avoid are:

  • High temperature charging
  • Keeping the pack idle at either low or high states of charge for a long period of time
  • Frequently cycling the pack charge between 80% and 100% SOC

If you avoid those bad habits, then everything else is pretty much out of your hands.

Obsessing over the pack health will ruin your enjoyment of the car.

I've followed your suggestions another other common wisdom since I purchased the car. By "Grandpa" driving I watched my battery SOH drop from 100% to 91%. If I can keep my battery SOH high and extend the useful life of the battery by changing driving habits, it's worth investigating to negate Nissan's inferior battery technology.
