Re: Is this LeafSpy data ok for 2014 with 62,000 miles?

First trip, 40 miles. 3.7 M/ kWh. Climate control on 68, 24F outside, and heat pump using about .8 kW. 26 miles remaining on the guessometer.

You really don't want to even look at the GOM. In my 2013, when it said 20 miles on the GOM I really had no more than 12 miles according to LeafSpyPro. That is a huge difference.

On my 40, I see the opposite. When GOM says I have 3 miles left, LSP says 20.

But LSP estimates are based on user input. I would reevaluate your math.

Here is the screen shot at the bottom of the pack. Not quite turtle but I took it down to the car reading SOC 7%. LeafSpy says 19%?

That pack is badly in need of equalization, and may have a bad or weak cell or three.

It was top balanced to 13mv. That is SOC 7%.

The weak cells are showing at the low SOC. I don't think that this is a normal low SOC balance...

Original battery. 5.5 years old and 62,000 miles. Still giving me 55-60 real world highway miles in 15F weather. Might go downhill fast though with me having to push it from 100% to 20% twice a day. It has about the equivalent of 800 full cycles on it now. If another 800 full cycle equivalent takes it to 70% SOH I will no longer make my range and be forced to sell it or replace the battery. 400 more work day trips?

The steering wheel heater is very hot. It's surprising how warm this can keep your whole upper body gaining heat through your hands. ACC set to 68 and fan speed 1 keeps the glass clear while using less than 1 kW. My knees feel the radiant cold through the glass. A small 12v electric blanket is my next purchase.

Why does LeafSpy show SOC 19% when the car showed 7%. 3.56V is obviously just about done with one cell at 3.50.

13 mV is barely what I would call acceptable on a full completed (finished balancing) charge. 6-9 mV is typical of a good pack.

The SOC reported by car or LS is based on calculated capacity of the pack. One has a hidden buffer, the other does not.

This is the reason there is no specific GID value for Turtle. Turtle is a voltage controlled situation. It comes on when it senses ONE cell hitting the critical voltage.

Now, despite one cell being close to that critical voltage, one could conceivably drive relatively far since there is still power in the pack. This is where Eco comes in. This is where gentle driving comes in.

Your scenario of driving from 100% to 20% daily will help bring the pack back into line (as long as there is no defective cells which appears unlikely in your case)

I don't recommend 100% charging generally but its Winter and you need the range so definitely do it. In Summer reevaluate to see if you can get away with charging to 80% or something lower.

Check your tire pressures. I would go no lower than 40 PSI "cold"
