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

[tomhanman]

Thank you xafalcon. He did just download the app, so it should be the latest. And I made him re-run the tests with a higher voltage on the 12v just in case. And he got exactly the same results. The soh (es in French) seems plausible but the rest is not applicable. Seems odd to get the same nonsense on two separate days, whilst getting the same clear perfect results twice on another battery.

Should the app reset the Ah too? Because i didnt see Ah to change.

thank you for the app and hard work .
Some questions for users . After the reset what did the guess"o"meter state ? New range or old ?
Secondly please confirm how long did it take to re-learn the values after to the correct SOH it would be interesting to know how many charge cycles is required to calibrate a LBC after such an event .

Gues"o"meter showed 160km on 24kWh battery. After 3 days it now shows 125km as is almost back to normal. SOH will be recalculated gradualy, but there is something with temperatures when SOH is not calculated. I have -2 outside so might not get SOH recalculated.
Most sad issue is 4 bars in the dash.

If you have a second, and an obd2 device, could you please post your Firmware version and CRC Reflash IV? I suspect they're tied to the firmware and not random (based on the limited number of BMS's I've checked)

Reason being, we can only generate the re-flashing seed/key pairs on a PC right now, so if the CRC IV's are tied to the firmware version, we can pre-calculate a seed-key pair file to distribute with the android reflash app - otherwise we'll need to use a web server to provide keys (which is fine, I'd just prefer it stand alone & offline) - once we get the right BMS to reflash, we can extract the full stand alone C function but right now, we're tied to the PC.

Android 12 or higher only for now.

El odómetro indicaba 160 km con una batería de 24 kWh. Después de 3 días, ahora indica 125 km y está casi volviendo a la normalidad. El SOH se volverá a calcular gradualmente, pero hay algo con las temperaturas cuando el SOH no se calcula. Tengo -2 grados afuera, por lo que es posible que no se vuelva a calcular el SOH.
El problema más triste son las 4 barras en el tablero.

A mí me pasó lo mismo el tablero se queda en 4 barras y marca 160km

What model and year is your leaf? we'll make notes in the app for which models won't increase the health bars

¿Qué modelo y año es tu Leaf? Tomaremos notas en la aplicación para qué modelos no aumentarán las barras de salud.

mi leaf es 2011

2011 y batería de 24kw

Hi @safetyuggs . Made a screenshot.

 

[safetyuggs]

Adding a few more useful features to the app, individual cell voltages. I still need to fix up auto scaling and overlay delta mV and balancing but it's coming along pretty well!

I have a 2013 leaf s that doesn't reset the health bars.

no change at all to them?

V1.00 - swipe left for a cell voltage bar graph. Let me know if I got the default scaling right! It doesn't yet update in real time, but I can add that in if needed.

No change at all. The GOM increases for about a day before it recalibrate to what it showed previously.

No numbers or information on the bar graph. Still doesn't reset the health meter. Reset cxlx does nothing.

 

[safetyuggs]

what android version are you on? it looks very different to my android 12 display...

 

[Tango47]

Android 14. Samsung Galaxy S24 Ultra

 

[safetyuggs]

Thx, I'll look Into it.

I suspect there is no text as it would be white on white...

 

[safetyuggs]

Ahh ok, so my phone has dark mode enabled by default, i'll force the same color scheme so your phone will show the same as mine.
