; ERROR: Only errors are logged
; WARNING: Errors and warnings are logged
; INFO: Errors, warnings and info messages are logged
; DEBUG: Errors, warnings, info and debug messages are logged
LOGGING = INFO

; --------- Battery Current limits ---------
MAX_BATTERY_CHARGE_CURRENT    = 80.0
MAX_BATTERY_DISCHARGE_CURRENT = 90.0

; --------- 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   = 3.50
; Float voltage (can be seen as resting voltage)
FLOAT_CELL_VOLTAGE = 3.40

; --------- 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
SOC_RESET_VOLTAGE  = 3.550
; Specify after how many days the soc reset voltage should be reached again
; The timer is reset when the soc reset voltage is reached
; Leave empty if you don't want to use this
; Example: Value is set to 15
; day 1: soc reset reached once
; day 16: soc reset reached twice
; day 31: soc reset not reached since it's very cloudy
; day 34: soc reset reached since the sun came out
; day 49: soc reset reached again, since last time it took 3 days to reach soc reset voltage
SOC_RESET_AFTER_DAYS = 5

; --------- Bluetooth BMS ---------
; Description: Specify the Bluetooth BMS and it's MAC address that you want to install. Leave emty to disable
; -- Available Bluetooth BMS:
; Jkbms_Ble, LltJbd_Ble
; Example for one BMS:
; BLUETOOTH_BMS = Jkbms_Ble C8:47:8C:00:00:00
; Example for multiple BMS:
; BLUETOOTH_BMS = Jkbms_Ble C8:47:8C:00:00:00, Jkbms_Ble C8:47:8C:00:00:11, Jkbms_Ble C8:47:8C:00:00:22
BLUETOOTH_BMS =

; --------- CAN BMS ---------
; Description: Specify the CAN port(s) where the BMS is connected to. Leave empty to disable
; -- Available CAN BMS:
; Daly_Can, Jkbms_Can
; Example for one CAN port:
; CAN_PORT = can0
; Example for multiple CAN ports:
; CAN_PORT = can0, can8, can9
CAN_PORT =

; --------- 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

; --------- 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 = 20
; 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 = 2


; --------- 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 80%
;          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 80%.
; Charge voltage control management enable (True/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

; 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 = 0.080

; -- CVL reset based on SoC option (step mode & linear mode)
; Specify how long the max voltage should be kept
;     Step mode: If reached then switch to float voltage
;     Linear mode: If cells are balanced keep max voltage for further MAX_VOLTAGE_TIME_SEC seconds
MAX_VOLTAGE_TIME_SEC = 240
; Specify SoC where CVL limit is reset to max voltage
;     Step mode: If SoC gets below
;     Linear mode: If cells are unbalanced or if SoC gets below
SOC_LEVEL_TO_RESET_VOLTAGE_LIMIT = 80


; --------- 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

; --------- Voltage drop ---------
; If you have a voltage drop between the BMS and the charger because of wire size or length
; then you can specify the voltage drop here. The driver will then add the voltage drop
; to the calculated CVL to compensate.
; Example:
;     cell count: 16
;     MAX_CELL_VOLTAGE = 3.45
;     max voltage calculated = 16 * 3.45 = 55.20
;     CVL is set to 55.20 V and the battery is now charged until the charger reaches 55.20 V.
;     The BMS now measures 55.05 V since there is a voltage drop of 0.15 V on the cable.
;     Since the dbus-serialbattery reads the voltage of 55.05 V from the BMS the max voltage
;     of 55.20 V is never reached and max voltage is kept forever.
;     By setting the VOLTAGE_DROP to 0.15 V the voltage on the charger is increased and the
;     target voltage on the BMS is reached.
VOLTAGE_DROP = 0.00
