SOC Stuck at 100%

[Honusnap]

Describe the bug

Since Yesterday the displayed SOC stay at 100% while my shunt say otherwise => Soc calculus problem The oinly thing i see strange in the log is the : 2024-09-21 08:20:21.993289500 INFO:SerialBattery:> Connection voltage: 53.79 V | Current: 7.5 A | SoC: 4% | SoC calc: 100%

SOC 4% ? Hell no it isn't at 4%, wna why SOC calc = 100% when conditions are not met for a 100% ?

How to reproduce

Nothing really to do .. it just happend without visible condition others then using the driver.

Expected behavior

SOC decrease at night.

; 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

; --------- SOC reset voltage ---------
; Description:
;     May be needed to reset the SoC to 100% once in a while for some BMS, because of SoC drift.
;     Specify the cell voltage where the SoC should be reset to 100% by the BMS.
;       - JKBMS: SoC is reset to 100% if one cell reaches OVP (over voltage protection) voltage
;     As you have to adopt this value to your system, I reccomend to start with
;     OVP voltage - 0.030 (see Example).
;       - Try to increase (add) by 0.005 in steps, if the system does not switch to float mode, even if
;         the target voltage SOC_RESET_VOLTAGE * CELL_COUNT is reached.
;       - Try to decrease (lower) by 0.005 in steps, if the system hits the OVP too fast, before all
;         cells could be balanced and the system goes into protection mode multiple times.
; Example:
;     If OVP is 3.650, then start with 3.620 and increase/decrease by 0.005
; Note:
;     The value has to be higher as the MAX_CELL_VOLTAGE : 3.650
SOC_RESET_VOLTAGE = 3.420

;     day 31: soc reset not reached since it's very cloudy

;     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

;          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 80%
;     Linear mode:
;          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 900 additional seconds to don't stress the batteries. Allow max voltage of

; --------- Cell Voltage limitation (affecting CVL) ---------
; This function prevents a bad balanced battery to overcharge the cell with the highest voltage and the bms to
; switch off because of overvoltage of this cell.
;
; Example:
;     15 cells are at 3.4v, 1 cell is at 3.6v. Total voltage of battery is 54.6v and the Victron System sees no reason to
;     lower the charging current as the control_voltage (Absorbtion Voltage) ist 55.2v
;     In this case the Cell Voltage limitation kicks in and lowers the control_voltage to keep it close to the MAX_CELL_VOLTAGE.
;
; In theory this can also be done with CCL, but doing it with CVL has 2 advantages:
;     - In a well balanced system the current can be kept quite high till the end of charge by using MAX_CELL_VOLTAGE for charging.
;     - In systems with MPPTs and DC-feed-in activated the victron systems do not respect CCL, so CVL is the only way to prevent the
;       highest cell in a bad balanced system from overcharging.
;
; There are 2 methods implemented to calculate CVL:
;   1. penalty_sum-Method (CVL_ICONTROLLER_MODE = False)
;      The voltage-overshoot of all cells that exceed MAX_CELL_VOLTAGE is summed up and the control voltage is lowered by this "penalty_sum".
;      This is calculated every LINEAR_RECALCULATION_EVERY seconds.
;      In fact, this is a P-Controller.
;   2. I-Controller (CVL_ICONTROLLER_MODE = True)
;      An I-Controller tries to control the voltage of the highest cell to MAX_CELL_VOLTAGE + CELL_VOLTAGE_DIFF_KEEP_MAX_VOLTAGE_UNTIL.
;      (for example 3.45V+0.01V =3.46V). If the voltage of the highest cell is above this level, CVL is reduced. If the voltage is below, CVL is
;      increased until cellcount*MAX_CELL_VOLTAGE.
;      An I-Part of 0.2 V/Vs (CVL_ICONTROLLER_FACTOR) has proved to be a stable and fast controlling-behaviour.
;      This method is not as fast as the penalty_sum-Method but usually smoother and more stable against toggeling and has no stationary deviation.

Any other information that may be helpful

An other thing i see is the "Cell populated" info .. where does it come from.. ? 32 cells ... ?

[mr-manuel]

What are your cell voltages? 4% SOC is reported from the BMS.

[Honusnap]

3.4V cell diff 0.007V Does the Calculated SOC depend on the SOC reported by the BMS ? Cause the BMS SOC maybe wrong, since i use SerialBattery for along time, the BMS reset 100% maybe have not been met for along time.

Please check this https://mr-manuel.github.io/venus-os_dbus-serialbattery_docs/faq/#why-is-my-battery-not-switching-to-floatbulk

[Honusnap]

Please check this https://mr-manuel.github.io/venus-os_dbus-serialbattery_docs/faq/#why-is-my-battery-not-switching-to-floatbulk

My charger is switching from float to bulk and vice versa without any problem. What part of your link do you think i should look at .. cause i can't see anything that would help to solve my problem here.

So to be clear the : SoC calc: 100% in the log is incorrect, the parameters are not met for 100% calculated SOC

[mr-manuel]

You should enable and check the additional fields in the GUI under SerialBattery -> Parameters page. There you find why the SOC is set to 100 %. Just follow the link from above.

[Honusnap]

You should enable and check the additional fields on the parameters page. There you find why the SPC os set to 100 %.

"on the parameters page", What page ? You mean in the config.ini ? What is SPC ?

[mr-manuel]

Just follow the link. SPC is a typo of SOC.

[Honusnap]

Useless directions, no problem... it's buggy .. will stay this way. It's not the first time that it happend .... like the high CPU load that you refuse for so many month and finally implemented .. you got a hard head.

[mr-manuel]

If you would follow the instructions from the link above and watch the short video, you would see, that there are a lot of useful informations that would help to get this problems sorted. If you don't want to follow the inscrutions, then I can't force you to do so.

There are over 9.000 installations out there, if only you have a problem it's very likely due to a very special configuration.

[mr-manuel]

You are also using a config.default.ini which does not match your driver version. Please install the latest nightly build, it will be released as the next stable shortly.

[mr-manuel]

Also, it the calculated SOC is reset by the driver, you should see something like this:
