Incorrect current readings

I recently bought Leaf Spy Pro (v0.38.80 en) for Android, using a Konnwei OBDII on a 2016 Leaf with 30kWH battery. Excellent app, lots of data - I'm down loading the CSV files and graphing them.

When I plot column 10 in the CSV, "Pack Amps", it gives half the real value. E.g. charging on an OpenEVSE at 240V, 12A, the EVSE meter reads about 11.4A and the CSV gives about -5.7. Charging on an EVduty EVC30T-05 at nominal 30A, 240V the CSV gives -15.

Leaf Spy gives you the current into or out of the battery. Since the battery is between 300 and 400 volts (depending upon SOC) the DC current at the battery (output side of charger) will be less than the current measured on the 240 volt AC input to the charger.

Frustrated: my 6th attempt to get a matching OBDII:
- 1 arrived, didn't work - connected to phone, Leaf Spy Pro didn't connect
- 2 were never even shipped: so, 2 30 day delays to get an A-Z guarantee
- The Konwei 902 doesn't appear to be available anywhere...
- I'm looking at 2 on my desk: Panlong and BLE... both recommended by users on Seattle Leaf Forum on Facebook.

Panlong works with Leaf Spy Lite, but not Leaf Spy Pro.
BLE doesn't even connect with my phone... so not selectable with Leaf Spy Pro.

I'm a software engineer - Are there utilities to help me debug why these are issues?
I very much want all the features Leaf Spy Pro offers...

I've been at this for 6 months - check my purchase iD - jlynker@gmail.com... bought Leaf Spy Pro way back in July or August...

I don't log on here very often so, if you would please, contact me via my email address. Thanks..

John

I suspect user error if it works w/Leaf Spy Lite but not Pro. Perhaps both apps are running? Kill both of them and start over. Perhaps there's just some flakiness that requires you to unplug/replug the dongle and/or restart the app? I often have to futz with this.

I bought the two at http://www.mynissanleaf.com/viewtopic.p ... 05#p432005 when I was a huge hurry because my 1st Leaf lease was going to end and I needed Leaf Spy to help me shop for a used Leaf. 1st one I tried worked off the bat. Never even bothered w/the second one.

Reboot your phone? I've used Leaf Spy Pro w/the dongle I mentioned across 3 phones w/o any issues: Samsung Galaxy S4, then S6 then Nexus 5X.

How are cycles counted? When i plug in its a charge cycle, or only when theres 0-100 (full battery cycle)?

Are you talking about the L1/L2 count?

If so, it has err... quirks. Se below.

if you are using a timer on a regular basis, you probably have closer to 450ish... Can't believe after all this time, we are still counting "plug in's" as a charge event...

Hi,
can i use Leaf spy pro to calculate the internal resistance in the battery?
I wonder how much the internal resistance is rising in cold weather (Norway).

Or is there already a graph somewhere showing internal restistance vs temperature?
