JKBMS B2A24S15P & v1.0.20230531 Never switches to FLOAT #927

Closed BipedalPrimate closed 8 months ago

BipedalPrimate commented 8 months ago

Describe the problem

As I understand it, the following parameters in config.ini determine when to switch to Float:

MAX_CELL_VOLTAGE = 3.450 FLOAT_CELL_VOLTAGE = 3.350 CVCM_ENABLE = False (Started with this set to True but never achieved 55.2v because of initially unbalanced pack - now balanced) CELL_VOLTAGE_DIFF_KEEP_MAX_VOLTAGE_UNTIL = 0.010 CELL_VOLTAGE_DIFF_TO_RESET_VOLTAGE_LIMIT = 0.160 MAX_VOLTAGE_TIME_SEC = 600 (note that I have tried setting this to 1 sec) SOC_LEVEL_TO_RESET_VOLTAGE_LIMIT = 90

It appears that all of these conditions have been met on a number of occasions yet Float is never achieved.

Am I missing something? If so, what?

MAX_BATTERY_DISCHARGE_CURRENT = 125.0

; --------- 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
MIN_CELL_VOLTAGE   = 3.150

; Max voltage can seen as absorption voltage

; --------- Bluetooth BMS ---------
; Description: List the Bluetooth BMS here that you want to install
; -- Available Bluetooth BMS:
; Jkbms_Ble, LltJbd_Ble
; Example:
;     1 BMS: Jkbms_Ble C8:47:8C:00:00:00

; --------- BMS disconnect behaviour ---------
; Description: Block charge and discharge when the communication to the BMS is lost. If you are removing the
;              BMS on purpose, then you have to restart the driver/system to reset the block.
; False: Charge and discharge is not blocked on BMS communication loss
; True: Charge and discharge is blocked on BMS communication loss, it's unblocked when connection is established
;       again or the driver/system is restarted
; BLOCK_ON_DISCONNECT = False
BLOCK_ON_DISCONNECT = True

; --------- 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
; LINEAR_RECALCULATION_EVERY = 60
LINEAR_RECALCULATION_EVERY = 30

; Specify in percent when the linear values should be recalculated immediately
; Example: 5 for a immediate change, when the value changes by more than 5%
LINEAR_RECALCULATION_ON_PERC_CHANGE = 5

; --------- 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
;                    oC 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 s 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%
;          OR
;          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%.
; Charge voltage control management enable (True/False).
; CVCM_ENABLE = True Changed temporarily to force 55.2v
CVCM_ENABLE = False

; -- CVL reset based on cell voltage diff (linear mode)
; Specify cell voltage diff where CVL limit is kept until diff is equal or lower
CELL_VOLTAGE_DIFF_KEEP_MAX_VOLTAGE_UNTIL = 0.010
; Specify cell voltage diff where CVL limit is reset to max voltage, if value get above
; the cells are considered as imbalanced, if the cell diff exceeds 5% of the nominal cell voltage
; e.g. 3.2 V * 5 / 100 = 0.160 V
CELL_VOLTAGE_DIFF_TO_RESET_VOLTAGE_LIMIT = 0.160

; -- CVL reset based on SoC option (step mode)
; Specify how long the max voltage should be kept, if reached then switch to float voltage
; MAX_VOLTAGE_TIME_SEC = 900   Temporarily changed to force Float

; Specify SoC where CVL limit is reset to max voltage, if value gets below
SOC_LEVEL_TO_RESET_VOLTAGE_LIMIT = 90

; --------- Cell Voltage Current limitation (affecting CCL/DCL) ---------
; Description: Maximal charge / discharge current will be in-/decreased depending on min and max cell voltages
; Example: 18 cells * 3.55V/cell = 63.9V max charge voltage
;          18 cells * 2.70V/cell = 48.6V min discharge voltage
;          But in reality not all cells reach the same voltage at the same time. The (dis)charge current

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

; Example:

;     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 = 0.040

Did you read the config.default.ini?

What you are saying is that FLOAT will never occur unless CVCM = TRUE regardless of the other conditions.

Thats correct.
