2013. Aze0

Quién hizo la aplicación se basó en un 2011 y entiendo que solo la probó en un banco de pruebas y en el banco no le da error como que se quedan en 4 barras, mis 2 leaf se quedaron en 4 barras pero si subieron los AH y me están entregando más km por carga

As i know, it uses internal batt temp sensors.. i would need to drop the battery. I hope some "launch" tool could do proper reset...

Thinking out of the box: if you have a garage, use a heat blanket to heat the battery! Remove the plastic shell and "glue" (without glue of course) to the battery box.

But its not clear when it is recalculated... i still need to drive and use the energy..

Yes, we are waiting for Safetyuggs to try the app on AZE0 bms. Hope he will manage to find a solution for AZE0.

There is service bulletin NTB20-001 for replacing battery packs via consult app in aze0 cars. After battery is replaced and registred there is needed another step

EV/HEV BATTERY GRADUAL CAP LOSS DATA CLEAR
17. Select EV/HEV Work support.
18. Select BATTERY GRADUAL CAP LOSS DATA CLEAR.

Maybe problem with 4bars is possible to fix by resetting VCM.

OR

second attempt as reset bars

try to send message 022108 to address 79B (LBC) via OBD diag tool.

Managed to recover Ah to 51Ah. Did many fast accelerations to heat up the battery, drove to zero SOC, reset system, drove again to zero SOC and charged on Chademo. Got batt temp to the 17 degrees and saw the Ah increase. Still 4 bars, but now i can use it again as daily car

OK So I've found the cause of the 4 bars - Setting SOH to 100% appears to cause one of the internal math values to be set to 41.11% SOH, which works out to 4 bars. It is the BMS that the sends SOC and SOH messages to the dash, not the VCM. I'll keep looking to see why it's being set to 41 and find a fix

Great! Maybe thats why i got Amps recalculated to 25Ah, that was some 40.88% SOH?

 

[safetyuggs]

It's possible, I'll know more soon

 

[safetyuggs]

Again, use at your own risk - This reset command will set the internal SOH variable to 100%, along with the 'external' can bus variable which is sent to leafspy etc...

 

[Geduxaz]

Will test and reply! Thanks!

Mine with 3 bars, is a improve the 4 bars bug\feature!
Keep the great job. Congrats.

Seems it does not change SOH, Hx. I set them to 90 to change, but they stay 100.
Thats with 1.02 version. I believe that is latest you posted.
Tried with contactors On, contactors Off, no changes. Charge number can be changed, SOH, Hx stays 100 as was set earlier and does not update anything.

Tested v1.0.2 on 2013 Leaf S. Reset SOH and Hx to 100, but bars are still 4(used to be 6). Do I need to do a charge cycle as well?

When resetting, indicated COX-98 HX - 50, the values \u200b\u200b100 and 100 were established, the bars of 4 divisions remained.

Finally got around to trying the BMS reset. Getting incorrect response received. Any thoughts @safetyuggs ? I recall you saying the firmware version looked wrong on my BMS, on dala's discord back in Dec on ver .07. might have something to do with it?

 

[tavsanist]

Tested v1.0.1 on 2015 Leaf. Leafspy says %100, dashboard 4 bars.
Will post if it changes..

Tried once again with SOHfix.apk, no change. It seems like SOHfix does not change the SOH value other than 100, unlike previous versions.
