Android App to View / Reset SOH, Hx, Lx, Cx, etc...

[Geduxaz]

I want to repeat, that Ah numbers did not reset in my two AZE0 leafs.. reset procedure did no change to Ah.

 

[safetyuggs]

That is exactly the same as my ZE0, the AH numbers did not change at all. Bars went to 12, hx to 100%, soh to 100%, AH remained the same

Eso es exactamente lo mismo que mi ZE0, los números de AH no cambiaron en absoluto. Las barras aumentaron a 12, HX a 100%, SOH a 100%, AH permaneció igual

Ami si cambiaron los AH y si siento una mejora en la batería y la regeneracion en los leaf que reinicie, les mando capturas de leafspy

 

[erikrangel]

¿Esto suena como el problema de 2018+ donde las barras bajaron? No estoy seguro de si se refiere a que después del reinicio de SOH, pasaron de 10 barras a 4 barras

Hola dala en los 2 leaf que reinicie paso lo mismo primero bajaron los AH y luego subieron, puede estar relacionado en bajón de AH con las 4 barras, y si estoy siento una gran mejora de rendimiento y regeneracion de carga, mis 2 leaf son 2011 con freno de mano eléctrico.

My leaf is 2013 AZE0 . After the reset Ah value did not change, but the battery bars dropped from 10 to 4.

Tried the app on my 2014 leaf and reset the SOH to 100 and said the HX was reset to 100% but showed HX as 97.66% on leaf spy, but battery bars stayed exactly the same and AH was unchanged.
I have in the past reset the bms with a topon diagnostic box and that was able to reset the SOH etc but could never reset the battery bars. I wonder if leafs 2013 or earlier can reset their bars and Nissan updated the firmware on later models so battery bars would not reset?
Also when I have reset the BMS before I have to take car out and drive somewhere before the reset on the AH actually changes, wonder if that same will happen to the AH with this app too?
Before and after photos with the app.

Yeah I found you need to drive the car or do a charge cycle for the reset to 'stick'. also, leaf spy's HX math is wrong, it'll never show 100% due to them dividing the raw value by 1024, vs 1000 that the bms code uses.

also, 7mV delta is crazy good for a pack with 80% SOH!

 

[Geduxaz]

Comming back to stock (close as posible) SOH and Hx values does not get out of 4 bars zone.

Is there any way to reset the bms to the state before the soh and hx modification? Thanks

I had this problem too (4 bars), the solution described in this post helped

Is your Leaf AZE0? Looks like 4 bars are only for AZE0. I will try to connect directly to bms can bus ant test this solution

I have a ze0, 2011

¿Tu Leaf es AZE0? Parece que las 4 barras son solo para AZE0. Intentaré conectarme directamente al bus CAN del BMS y probar esta solución.

Por favor si te resulta éxito conectar el obd a la línea can del BMS y resolver lo de las 4 barras publicaro y toma fotos para ver cómo es la conexión

Try like this, let about 2-3 kwt remain, go to Chademo, reset battery and put to charge till charging speed will drop to 6 kwt/h and finish to charge at AC till the end.
By the way one Chademo charge per month will keep the battery in good SOH even it will go up.

Is your leaf AZE0 or it is ZE0?

Hi, my Leaf is ZE0 from 2011 first 10000 made.

I drove my car and it did reset, but...... it reset back to the 79.74% SOH it was before I reset it with app and like some others the battery bars went from 11 down to 4 and its stuck there. Did do a full 100% charge to see if that made any difference but still only 4 bars showing , but estimated distance is the same as it was before..

I tried to do reset directly on HV CanBus. I took OBD adapter and rewired CANBUS to 12&13 pins (HV Canbus).
Did connect to battery, did reset SOH, but AmpHours did not reset, stayed same 51Ah.. Still 4 bars in dash.
Leaf AZE0.
What should i try next?

I would just wait until the app is updated, seems to be a theme with the azeo to go to 4 bar, but no problem with the zeo

I have nissan leaf 2015
After resetting the soh the 12 bars stuck on 4 bars while the car was 8
Any idea how to fix that?
