Re: Leaf Spy and Leaf Spy Pro

Hi all,
I am new to this forum. If I am posting in the wrong topic then please direct me to the correct topic. Thank you in advance.

LeafSpy Pro android. Ver 0.53.182 2018-0E2*0
A possible bug (or operator error)
I have Settings - Units Feet, mile, mph selected. I notice on screen-1 the 'odo=22,819 mi' is not matching miles on my 2018 leaf. When I change Settings to Meters, km, km/h then 'odo=36724 km' then the mileage match the miles on my Leaf but the unit is not correct. It appears that the underlying code is is displaying the mileage opposite of the selected setting. Temperature 'F' and tire pressure 'PSI' are shown correctly.

Is anyone else with same version experiencing the same problem with mileage?
Is there a setting I am missing or is it a bug in the code?

A question about screen-1 and the red/blue bars.
I have a 40kwh battery. The main screen reports 12 0f 12 bars. I am not the original owner and this is my first use of LeafSpy.
I have a screenshot of screen-1 that I can post (minus the VIN) that shows the bars in alternating red-blue-red-blue... from 1-96. All the bars mostly the same height min/avg/max (3.797 3.887 3.901 (104mv). Bar 75 is red and shorter than all the rest at 3.797.

Does this mean that cell 75 is bad, going bad or just weaker than the rest?
Is 3.797 with an average of 3.887 typical or should all the bars be more equal?

Thank you,

I got stuck at the dealer for 2 hours for them to clear a DTC and test the fast charge. :x (Looks like they just wanted a 2 hour warranty charge to corporate.)

LeafSpy PRO for iOS will not clear DTCs on a 2022 Leaf which I found out while at 6% at a fast charger. Also, other LS features do not work.

I do not recommend spending the $20 on iOS LS PRO for missing and non working features. Use the Android version.

Re: Leaf Spy and Leaf Spy Pro

Are the 12 bars mentioned, the capacity bars (small bars on the extreme right) or the state of charge bars (long ones)?

The lower your state of charge, the larger the difference between cell voltages will be. The voltage difference after a full charge should be very close, less than 20mV(?). As you get below LBW, the difference increases dramatically.

Cell 75 is problematic if it is that far out of balance when fully charged. It will also cause a premature shut down when you are at low SOC or when you draw a lot of power in cold weather. Need more data to determine whether the cell is weak, bad, deteriorating or if the battery hasn’t had the opportunity to balance itself recently.

Posting your screenshot will help.

Surprised that the more knowledgeable members haven’t responded yet.

Re: Leaf Spy and Leaf Spy Pro

That difference in cell voltage, at or near a full charge, probably indicates a marginal cell. Not bad enough to get replaced, but possibly of concern in the future. As 91040 noted, a weak cell can trigger "turtle" mode or even a shutdown under load at a lower state of charge.

Re: Leaf Spy and Leaf Spy Pro

As much as I detest duplicate posts, you should probably post your opinion in the LeafSpy iOS thread on this forum.

Re: Leaf Spy and Leaf Spy Pro

91040,
The 12 of 12 bars are on the cars screen where the speedometer is.

I will take a screen-1 screen shot at 100% charge.
What mV scale should I take the screen shot at?

I found a setting that changes the odo to match my miles. The setting is only shown when Leaf Spy (LS) is connected to the dongle. However the VIN number is not correct.
How to get LS to display the correct VIN?

I understand that fast DC charging should be avoided du to causing battery degradation. (Please correct me if I misunderstand)
The Nissan charge cord can charge at 120V,12A (1.44kW) or 240V,30A (7.2kW but reduced by the onboard charger to 6.6kW).
Is it less harmful to the battery to charge it at 1.4kW as compared to 6.6kW?

Thank you,

Re: Leaf Spy and Leaf Spy Pro

Please ignore my comments about the bars. They are applicable to the first generation LEAF only, not yours. A picture of that display would help or if someone with a generation 2 Leaf would chime in…

Any mV scale that has legible numbers is fine. A LeafSpy screen shot at full charge and a second below Low Battery Warning (or VLBW) will provide good information.

Photos for this forum need to be hosted elsewhere, then linked here.

The charging specs of the portable EVSE are correct. On 240V, the Leaf draws about 27A.

It is better to avoid Quick Charge (DC charging) when the traction battery is hot. Otherwise, use it as necessary. Search this forum to learn what that temperature threshold is. My guess is around100F. Also, avoid Quick Charging above 80% capacity because the charging speed slows down drastically and the increased heat it causes.

Any difference in stress on the battery between 120V charging and 240V is insignificant. However, 240V charging is more efficient since both have a similar power draw running the cooling system.

I don’t have any insight into the VIN number issue.

Cheers.

Re: Leaf Spy and Leaf Spy Pro

I confess. I didn't read over 200 pages so I may be asking dumb questions. I did see one post say don't use the iOS version, use Android. How do you do that if your device is iOS, iPhone or iPad? Do you need any physical thing like an OBD-II scanner etc. to use with this? How soon after buying a new Leaf does one need to use this?

Re: Leaf Spy and Leaf Spy Pro

Just get a $30 android phone, and a Bluetooth "dongle" (Onboard Diagnostic Port reader) like the one in my signature. Not all of them are compatible with the Leaf (this one is) so get one that is recommended here. You can leave them both in the car - but don't leave the dongle plugged in all the time. There is no hurry unless your car is exhibiting problems or trouble codes.

What happens if it is plugged in all the time? Power drain? Or some other evil interaction? :)
