Any other information that may be helpful

what can i do to become the soc value from the BMS

mr-manuel commented 4 months ago

The driver can only get, what the BMS is sending. Have you the same problem with other stable releases?

stixif commented 4 months ago

yes in all versions... the BMS App shows 100% for both Packs

but in VenusOS i geht 96 and 100...

mr-manuel commented 4 months ago
  1. Is this only happening when the batteries are on 100%?
  2. Does the SoC match, if the batteries are below 90% like 60%, 50%, 40%, 10%, 0%?
  3. Please enable GUI_PARAMETERS_SHOW_ADDITIONAL_INFO = False and send me some screenshots of both batteries and the parameters page. You have to scroll down. Not all data will fit on one screenshot. https://github.com/mr-manuel/venus-os_dbus-serialbattery/blob/ea4a175cca67d34dc26f7936363127673f027729/etc/dbus-serialbattery/config.default.ini#L408-L412
  4. Did you restart the driver, when the batteries where both 100% in the app? If yes are the logs above from that situation? If not please reboot/reinstall and post the logs again.

I don't think there could be done much, since the driver is displaying the SoC as it is send from the BMS. No manipulation in this case.

stixif commented 4 months ago

Hi, sorry for my late answer...

  1. no... its all the time...

  2. no...

  3. here you have... 1. batpack1 / 2. batpack2 image image

  4. this logs are from an new reinstalled and rebootet one...

the Difference is in the Consumed AmpHours

mr-manuel commented 4 months ago

For 2. we need some more measurements, with comparison of different SOC states from BMS and the driver.

For 3. you have to scroll down, below "Discharge Current Limit (DCL) are more fields, if you enabled it in the config.ini and reinstalled the driver.

stixif commented 4 months ago

Hi, and Tanks... For 2. Screenshot_2024-07-07-11-59-22-376_com android chrome Screenshot_2024-07-07-11-59-32-886_com jiabaida bms Screenshot_2024-07-07-12-00-02-025_com jiabaida bms

For 3. I do an Reinstall but get Not more information... Should i deinstall and Install new?!?

mr-manuel commented 4 months ago

What about the second battery?

Which BMS are you using? LLT, JBD or another one?

  1. Have you added the value to the config.ini?
stixif commented 4 months ago

for the Pictures... In VenusOS Bat1 = 61 Bat2 = 73

in the APP Bat1 = 63 Bat2 = 67

for 3. yes i do... GUI_PARAMETERS_SHOW_ADDITIONAL_INFO = True

and i do /data/etc/dbus-serialbattery/reinstall-local.sh and test a new install and reboot but i get not more...

now i´m on the Stable v1.3.20240705

stixif commented 4 months ago

and now the sun comes out and it would not load my battery with v1.3.20240705

with the "old" Beta it works v1.3.20240615beta" ^^ i reinstalled now

but the Problem with the Soc is the same...

stixif commented 4 months ago

now i have mor Information... if i use this config all works well

; Show additional info in GUI -> Serialbattery -> Parameters ; This will show additional information to better understand how the driver works ; and what values are currently set which are not shown elsewhere in the GUI ; You have to scroll down to see the additional information ;GUI_PARAMETERS_SHOW_ADDITIONAL_INFO = True

and with this config i geht low Voltage warning... (so it do not load my batteries)

; Show additional info in GUI -> Serialbattery -> Parameters ; This will show additional information to better understand how the driver works ; and what values are currently set which are not shown elsewhere in the GUI ; You have to scroll down to see the additional information GUI_PARAMETERS_SHOW_ADDITIONAL_INFO = True

with both Versions... v1.3.20240705 and v1.3.20240615beta

so now i use v1.3.20240705 with my first config

mr-manuel commented 4 months ago

On my mobile phone I did not saw the second screenshot.

Which BMS are you using? LLT, JBD or another one?

stixif commented 4 months ago

the JBD

mr-manuel commented 4 months ago

Ok, thats very strange, that only you have this issue. You have also the model and hardware version?

stixif commented 4 months ago

hmmm sorry ;) Pack1 image

Pack2 image

mr-manuel commented 4 months ago

Have you the possibility to connect one BMS over Bluetooth? Would be interesting to see the result there.

mr-manuel commented 4 months ago

@idstein @Jaco-TTT @packrat1969 @wherzig @sledge2019 @pmarches have you also this problem?

stixif commented 4 months ago

i connect over BLE and have the same issu... in the App 82% and in VenusOS 80%

Jaco-TTT commented 4 months ago

@Jaco-TTT have you also this problem?

Cannot comment, as I'm currently running without the software. I do know the SOC from the BMS, compared to Inverter SOC versus BMV(Smartshunt) SOC always differs.

mr-manuel commented 4 months ago

@stixif now the debugging with GUI_PARAMETERS_SHOW_ADDITIONAL_INFO was fixed. Install the latest nightly and post the screenshots of the parameters page (should be around 5 screenshots).

stixif commented 4 months ago

Hi, Thanks! Bat1: image image image image image

Pack2 image image image image image

mr-manuel commented 4 months ago

There are no signs of any issues. Can you request the protocol documentation from your seller?

stixif commented 4 months ago

I will ask... but I don't have high hopes

stixif commented 4 months ago

hi Manuel, I got something... JBD communication protocol new-RS485,RS232,UART.pdf

i hope it helps...

mr-manuel commented 4 months ago

I found something: https://github.com/Louisvdw/dbus-serialbattery/issues/769#issuecomment-1720805325

Can you check that values on your end?

Please also install the latest nightly. If you already have it installed, please reinstall it. Then post fresh logs here, they should contain some important values to understand the problem.

stixif commented 4 months ago

yes here the same... i have total capacity and cycle capacity. Bat1 total capacity = 280 cycle capacity = 260 current1.txt

Bat2 total capacity = 279,9 cycle capacity = 260 current2.txt

From the Log... INFO:SerialBattery:soc: 69 - self.soc: 66.87 soc is the same like the BMS APP

mr-manuel commented 4 months ago

@idstein do you know maybe, why the cycle capacity was used and not the total capacity?

Strange, that the app also do not use the cycle capacity, since with time and degradation the total capacity gets less.

@stixif install the latest nightly, I changed it to test in the meanwhile.

stixif commented 4 months ago

i got this error in the log

Not exactly the same :) we are getting closer. I updated the code again. Else you can write me on Discord to get access to your system. That would speed things up a bit.

mr-manuel commented 4 months ago

It should be solved now. Found a typo.

stixif commented 4 months ago

now it works...

but batpack1 is 90% in VenusOS and on the BMS 100% but the consumed AmpHours are 28Ah

and batpack2 is 100% in VenusOS and BMS consumed AmpHours 0Ah

but if i disconnect batpack2 it will not load batpack1

mr-manuel commented 4 months ago

Consumed Amp hours in the app or the driver?

stixif commented 4 months ago

in the driver... but it looks like the same in the App (280AH - Remaining 252AH)

The driver uses the consumed amp hours to have a higher resolution on the SOC. Maybe there is a wrong setting in your BMS? You could try a factory reset of the BMS and see the results.

If the battery is full, is the remaining capacity same as the capacity or the cycle capacity?

I add again the logging, so we see whats happening.

@stixif can you install from the troubleshooting-llt-jbs-soc branch and provide fresh logs?

See Install a specific branch if you don't know how to install a specific branch.

stixif commented 4 months ago

@mr-manuel i do...

i download it... https://github.com/mr-manuel/venus-os_dbus-serialbattery/archive/refs/heads/troubleshooting-llt-jbs-soc.tar.gz

and rename it and copy to "/var/volatile/tmp/venus-data.tar.gz"

and install with option 8 of the script

From the logfiles the version was not installed somehow. Could you write me on Discord so that I could check your system?

stixif commented 4 months ago

@mr-manuel ??? what is discord... i dont know sorry or can you tell me how i can install your version?

mr-manuel commented 4 months ago

See Install a specific branch if you don't know how to install a specific branch.

try this

stixif commented 4 months ago

@mr-manuel sorry... now I got it! ;) (i create the venus-data.tar.gz by myself... i never done this before...) current2.txt current1.txt

current1:

INFO:SerialBattery:soc (BMS): 99 - self.soc (calc): 99.5 - soc_2 (calc): 107.12 - capacity: 27990 - self.cycle_capacity: 26000.0 - capacity_remain: 27850

current2:

INFO:SerialBattery:soc (BMS): 100 - self.soc (calc): 89.55 - soc_2 (calc): 96.44 - capacity: 28000 - self.cycle_capacity: 26000.0 - capacity_remain: 25075

soc: comes directly from the BMS self.soc: round(100 * capacity_remain / capacity, 2) soc_2: round(100 * capacity_remain / self.cycle_capacity, 2) capacity: comes directly from the BMS self.cycle_capacity: comes directly from the BMS capacity_remain: comes directly from the BMS

So the problem here is, that your BMS shows inconsistent data. The SOC is 100%, but the remaining capacity has not reached at least the cycle_capacity in the second case. In the fist case, it's even exceeding this value.

Please ask your seller why that is the case and why this values don't match. Maybe it's a settings issue.

SOC is set to BMS SOC with https://github.com/mr-manuel/venus-os_dbus-serialbattery/commit/a7b0c4bad4085cacb5a9bd78283cc53796191c68.

Since this is a different problem open a new issue and provide correct logs. Check the documentation on how to provide correct logs. For this issue the timings were not needed, but for your current problem they are.
