1 year ago This will not work, you cannot run a INI file root@einstein:~# /data/etc/dbus-serialbattery/config.default.ini
You have to edit it with a editor like nano: root@einstein:~# nano /data/etc/dbus-serialbattery/config.default.ini
Make your custom changes in the config.ini and not in the config.default.ini. https://louisvdw.github.io/dbus-serialbattery/general/install#settings-locationpath

1 year ago Unfortunately not. Just read correctly the documentation and my post above.
Alone this command nano /data/etc/dbus-serialbattery/FILE_NAME shows me that you did not read the documentation, but only copy and pasted the command you found. If you were able to edit the utils.py I don't know, why you are not able to edit the config.ini...
Here again the links to the documentation. Read all and it will work.

1 year ago I'm really not good, I spent several hours trying to change the settings but I can't do it...
I don't know if it's a translation problem as I'm French and don't speak English.
Attached is a screenshot, is this the right way?

1 year ago Try deepl.com instead of Google translate. I speak four languages, but not french.
The file should look like this, so you are close.

MAX_BATTERY_CHARGE_CURRENT = 50.0
MAX_BATTERY_DISCHARGE_CURRENT = 60.0thank you for your patience I made an error that bugged the system I can't get the V1.0.0 version to work I can only manage to install v0.14.3 Is this normal? Thank you

1 year ago I think the biggest problem in your case is the language barrier.
You can uninstall and remove the driver and then reinstall it.

1 year ago I have uninstalled several times and reinstalled like the screenshot and I have version 0.14.3 and not V1.0.0.
I do not understand why V1.0.0 is the latest version recommended?

commented
1 year ago I do not understand why V1.0.0 is the latest version recommended?
Because it contains a lot of fixes and improvements. Shortly it will be released as stable version.

1 year ago Hello, I have just installed the new version v1.0.20230531. It's great, many thanks for all the work you've done. But I still can't modify the CCL and DCL.
I tried with this code but still no change. I don't understand what I'm doing wrong.
Can you enlighten me?
Thank you

MAX_BATTERY_CHARGE_CURRENT = 70.0
MAX_BATTERY_DISCHARGE_CURRENT = 120.0
; --------- Cell Voltages ---------
; Description: Cell min/max voltages which are used to calculate the min/max battery voltage
; Example: 16 cells * 3.45V/cell = 55.2V max charge voltage. 16 cells * 2.90V = 46.4V min discharge voltage
MIN_CELL_VOLTAGE = 2.900
; Max voltage can seen as absorption voltage
MAX_CELL_VOLTAGE = 3.450
FLOAT_CELL_VOLTAGE = 3.375
; --------- Charge mode ---------
; Choose the mode for voltage / current limitations (True / False)
; False is a step mode: This is the default with limitations on hard boundary steps
; True is a linear mode:
; For CCL and DCL the values between the steps are calculated for smoother values (by WaldemarFech)
; For CVL max battery voltage is calculated dynamically in order that the max cell voltage is not exceeded
LINEAR_LIMITATION_ENABLE = True
; Specify in seconds how often the linear values should be recalculated

; --------- Charge Voltage limitation (affecting CVL) ---------
; Description: Limit max charging voltage (MAX_CELL_VOLTAGE * cell count), switch from max voltage to float
; voltage (FLOAT_CELL_VOLTAGE * cell count) and back
; False: Max charging voltage is always kept
; True: Max charging voltage is reduced based on charge mode
; Step mode: After max voltage is reached for MAX_VOLTAGE_TIME_SEC it switches to float voltage. After
; SoC is below SOC_LEVEL_TO_RESET_VOLTAGE_LIMIT it switches back to max voltage.
; Linear mode: After max voltage is reachend and cell voltage difference is smaller or equal to
; CELL_VOLTAGE_DIFF_KEEP_MAX_VOLTAGE_UNTIL it switches to float voltage after 300 (fixed)
; additional seconds.
; After cell voltage difference is greater or equal to CELL_VOLTAGE_DIFF_TO_RESET_VOLTAGE_LIMIT
; OR
; SoC is below SOC_LEVEL_TO_RESET_VOLTAGE_LIMIT
; it switches back to max voltage.
; Example: The battery reached max voltage of 55.2V and hold it for 900 seconds, the the CVL is switched to
; float voltage of 53.6V to don't stress the batteries. Allow max voltage of 55.2V again, if SoC is
; once below 90%

; The battery reached max voltage of 55.2V and the max cell difference is 0.010V, then switch to float
; voltage of 53.6V after 300 additional seconds to don't stress the batteries. Allow max voltage of
; 55.2V again if max cell difference is above 0.080V or SoC below 90%.

; If you are using a SmartShunt or something else as a battery monitor, the battery voltage reported

; Example:
; cell count: 16
; MAX_CELL_VOLTAGE = 3.45
; max voltage calculated = 16 * 3.45 = 55.20
; CVL is set to 55.20 and the battery is now charged until the SmartShunt measures 55.20 V. The BMS
; now measures 55.05 V since there is a voltage drop of 0.15 V. Since the dbus-serialbattery measures
; 55.05 V the max voltage is never reached for the driver and max voltage is kept forever.
; Set VOLTAGE_DROP to 0.15
VOLTAGE_DROP = 0.00nano /data/etc/dbus-serialbattery
This for sure could not work. Please describe step for step what you did. Did you check the documentation?
