Re: Leaf Spy and Leaf Spy Pro

hi,

i am currently extensively testing my new leaf which i received yesterday! i am writing a german blog but here is a short high speed highway video: https://www.youtube.com/watch?v=p8RuaKMkmGw

leaf spy pro worked well with my european leaf, it seems it never lost connection with my lelink (v1) dongle but i didnt' evaluate the stored logs yet.

@Turbo3: there seems to be a little bug, the "outside temp" is shown in fahrenheit although i have everything set to Celsius. i am using the latest android beta version.

edit: another question, on the tablet display i saw regen values of more than 50kW but i can't see them in the log files? how is that? it only goes to -20596 as max value?

Go into Settings/Units and select the option to Convert Outside Temperature.

There is no way for LeafSpy to tell the units used as that is not on the CAN bus only the temperature value.

I will need to look into you other question.

ah, thank you! i seem to have missed this setting :)


is there a cool way to visualize the CSV files? what do other people usually use or which columns do you use for excel charts? i did some extensive tests and have 2x 2.5MB log files for 2 days and want to visualize my road trip. i am also thinking about a map showing my GPS coordinates with the associated infos but i am unsure how to do that.

another question, is it possible to somehow control the PTC heater and disable it via CAN bus (or leaf spy in the future)? in my tests i had no problems reaching 200km (124 miles) on the highway where the outside temperature was above zero. the next day i drove 165km (102 miles) and i barely made it with the 40kwh nissan leaf, the temp was a bit below zero and the heater element often kicked in. i also suspect the PTC heater besides strong wind and other topology.

The android store listing still recommends a different model!

[quote="brycenesbitt"]The android store listing still recommends a different model!

https://play.google.com/store/apps/deta ... af_Spy_Pro
"The previously recommended Bluetooth Konnwei KW902 OBDII adapter is also no longer recommended "
"The recommended one is the LELink available from Amazon."

What recommendation are you seeing?

Ok.... when I got my LEAF, Hx was at 99.86% In 2 days, it went over 100% and has never looked back. I am now wondering if it is now a counter of sorts as its now at 115.34% and I had long given up predicting where it will peak.

In fact the pack and LEAF Spy readings have been VERY unusual.

I started

ahr = 115.05
SOH = 99.66
Hx = 99.86

"Every" day my ahr and SOH have dropped (a few times they stayed the same but those generally happened because I drove under 20 miles that day)

While my Hx has risen....meteorically.

Don't get me wrong, I am hardly seeing massive degradation. Current readings

ahr = 114.65
SOH = 99.25%
Hx = 115.34%

Sooo.... is there something wrong with LEAF Spy? Is anyone else seeing this?

A number of years ago I asked if you could calculate and display the battery resistance of the Leaf as the LeafDD device does.
If I remember correctly, you added it to your app on one of the screens. Now I can't find it. Have I overlooked something
or did you remove it? If it's still in your app, battery resistance values from the three Leaf batteries, 24/30/40 kWhrs, could
be measured and compared to better understand how battery degradation varies as a function of battery resistance.
Your info section indicates that Hx may be a measure of battery resistance.
Leaf SL MY 9/13: 66K miles, 50 Ahrs, 5.2 miles/kWh (average), Hx=70, SOH=78, L2 charges to 100% > 1000, max battery temp < 95F (35C), min discharge point > 20 Ahrs

This is pretty widely known - even I know it. Why are you looking for a measure of internal resistance other than Hx and SOH when they correlate so well with degradation?

PLEASE don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

From the other thread; viewtopic.php?f=27&t=25519&start=40
I posted:


It would be insightful, if those with an '18 Leaf, or the 30 kWh, would use LeafSpy and post the value for the battery's internal resistance.
This would provide a key parameter of their battery chemistries and the thermal effects from multiple QCs/driving leading to battery
degradation. That data (battery resistance) for the earlier Leafs have been posted. If one assumes that the later Leafs have the same
battery thermal resistance to ambient, but a greater series resistance, those batteries would potentially remain hotter longer from
QCs/driving. The implication then, given the lack of TMS, is greater battery degradation than earlier Leafs.


If Hx is an actual measure of battery resistance (ohms or mohms), then assigning a % to doesn't make sense unless the Hx implies
a percentage of a battery resistance relative to 100% SOH. So with Hx equal to 115%, that would indicate battery resistance is now 115%
greater than when it was new - hard to believe. More likely if Hx is related to battery resistance, then it's in mohms and not %.
