Re: Leaf Spy and Leaf Spy Pro

Mon Feb 27, 2017 4:44 pm

I recently bought a used Nissan Leaf with 74000 miles still showing 11 battery bars.
Curious to see how close to losing another I bought Leaf Spy Pro and the recommended CHEERLINK® KONNWEI KW902 Mini Bluetooth Wireless OBD-II dongle..
Most everything except the cell pack voltage charts and a few related things work fine..
How can I get the cell voltages to display.. I've tried setting the shunt value at both 8412 and 4812 and still get a blank screen.
Is this a OBDII problem or a settings problem?
Thanks
Bill

I purchased the Konnwei KW902 as recommended by Leaf Spy, After plugging it in my 2012 Leaf went haywire and the display in the leaf showed multiple errors. I could not even power off the leaf. After unplugging I was able to turn the leaf off and it still showed multiple errors but was now able to power off the leaf. Has anyone else experienced this issue? After multiple power cycles to the Leaf, I have now gotten rid of the errors.
Why would this device cause such issues? Is this a fake device or does my leaf have other issues?
Any help would be appreciated.

Hi,
How do I find battery manufacturing date from LeafSpyPro? I cannot find it even in service menu....
Does LeafSpyPro able to show 12V battery current?

Manufacturing date of the car is on the label on the frame when you open the drivers door. If it is a replacement battery, you would need to contact Nissan.

Only Voltage for the 12V battery.
1st Capacity Bar loss 30k mi 16mo
2nd- 49k mi 25.5mo 51.5Ah
3rd- 73k mi 36.5mo 46.9Ah
4th- 86.5k mi 43mo 42.6Ah
5th- 101k mi 50.5mo 38.4Ah, end 36.1Ah
New Battery 9/28/15 104k mi 66.1Ah
1st- 160.5k mi 34mo 54Ah
2nd- 184.4k mi 53mo 49Ah

I would be prepared to pay for this feature.
One idea I had is based on the OpenEVSE charging station, which by its open source nature is modifiable by someone with the necessary expertise. If you do not have such expertise, maybe you could ask the OpenEVSE community about adding this feature.
I just started wrapping my solution to this up. I put an Arduino Nano uC* with a nrf24L01+ radio inside my OpenEVSE, and connecting the serial port to the OpenEVSE.

Then I have another uC in the car that is connected to the EV bus, it picks up the SOC data and transmit it to the uC in the OpenEVSE. The uC in the OpenEVSE also receives temperature from the plugs and a Target SOC from the car among other thins, and issues the needed serial RAPI command to OpenEVSE to stop charging when target is reached or reduce current draw if its a worn down outlet what is getting to hot to pull 3.6kW from.

I'm not sure how feasible it is to add the functionality directly to OpenEVSE as the current code pretty much uses nearly all available flash.

I would love to be able to send a CAN command to stop the charge instead, as currently it will not work with public Type2 chargers that is becoming the new standard here. (Not without using a Type2 to IEC outlet and then to my OpenEVSE)

Hi - I'm very interested in your project. I purchased my 2013 model S a week ago and I have an OpenEVSE on the way as well as a Pi and a Bluetooth OBD-II adapter I was planning to use for a similar project. Do you have a website or other post that has more details on what you've done so far?

Thanks,
Jeff

Most likely the draw of the KW902 pulled your 12v battery down lower than it wanted to be and you got the Christmas tree dash lights. Change your lead-acid 12v battery. Make sure not to leave the KW902 plugged in unattended. You can probably use the KW902 without replacing your lead-acid battery but make sure you have the car fully powered on and ready to drive first.

Hi everyone. Although I joined this forum in the summer of 2014, this is my first post. I'll write up a proper intro in the Introductions section soon, but in the meantime I had a question about the display I see using Leaf Spy Lite on a Moto G4 running Android OS 6.0.1 Marshmallow.

I'd like to upgrade to Leaf Spy Pro but the main display ("Bat Stats") showing all 96 cells descends below the x-axis to obscure information about the battery voltages and temperature (I think) -

Image

The "Voltage Histogram" page, on the other hand, looks fine -

Is this a problem with the app only on my phone? I didn't want to pay for the upgrade and still have this issue.

Another simple question, and I apologize if it's been asked to death in the 150+ pages of this thread, but is there an up-to-date FAQ or user manual somewhere? I can guess simple things like 13.04V 2.09A indicates the voltage and current draw on the 12v battery, and I do know what SoC means, but a manual would still be a good thing.

Thanks in advance,
- Jim from Austin, TX

Yes, there is a manual in the app itself.

For me, go to the 3 vertical dot menu > About & Help > Application Help. At the top, it also contains instructions on how to receive a PDF of it.

'19 Bolt Premier
'13 Leaf SV w/premium package (owned)
'13 Leaf SV w/QC + LED & premium packages (lease over, car returned)

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

Hello,

I have been using a KONNWEI OBDING tool. I scanned a Nissan Leaf and I could get the information to an excel sheet.
I was able to figure out the voltages of the 96 paired cells.


I need to know how can we physically identify the particular paired cell and battery pack 1,2 & 3?

For Example: How can we find out the exact location of the CP10? In which battery pack is it located?

Thank you!

I think the cell-pair numbering matches the module locations shown in the service manual. Example: Cell pairs 1and 2 would be in module 1; cell pairs 3 and 4 would be in module 2; ... and cell pairs 95 and 96 would be in module 48.
