Using external current sensor (smart shunt) #1059

Closed squowse closed 1 month ago

squowse commented 1 month ago

Describe the problem

I have successfully enabled SOC_CALCULATION in the driver config.ini file. This seems to be working and resetting to 100% correctly.

I changed the EXTERNAL_CURRENT_SENSOR_DBUS_DEVICE to the path found by dbus-spy. First time after reboot, VRM came up with the warning "realtime connection disabled due to gx device overload". The VRM interface did not update.

I disabled the external current sensor in the config.ini, rebooted, tested and then re-enabled it exactly the same. Now it appears to be working but the current displayed in VRM does not match the current shown using Victron Connect app simultaneously. The rounding is also wrong and is reminiscent of the BMS current reading.

BLUETOOTH_BMS = Jkbms_Ble C8:47:8C:E4:57:F5

; If you want to add custom values/settings, then check the values/settings you want to change in "config.default.ini"
; and insert them below to persist future driver updates.

; Example (remove the semicolon ";" to uncomment and activate the value/setting):
; MAX_BATTERY_CHARGE_CURRENT = 50.0
; MAX_BATTERY_DISCHARGE_CURRENT = 60.0

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

; --------- 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   = 3.525
; Float voltage (can be seen as resting voltage)
FLOAT_CELL_VOLTAGE = 3.325

; --------- SOC calculation ---------
; +++ This has nothing to do with "SOC reset voltage" in a section above +++
; Description:
;     Calculate the SOC in the driver. Do not use the SOC reported by the BMS
; SOC_CALCULATION:
;     True: Calc SOC in the driver, do not use SOC reported from BMS
;         - The SOC is calculated by integration of the current reported
;         - The current reported can be corrected by the map
;           (SOC_CALC_CURRENT_REPORTED_BY_BMS, SOC_CALC_CURRENT_MEASURED_BY_USER)
;         - The SOC is set to 100% if the following conditions apply for at least SOC_RESET_TIME seconds:
;             * Highest cell voltage is higher or equal to MAX_CELL_VOLTAGE
;             * Current is lower than SOC_RESET_CURRENT
;         - The SOC is set to 0% if the following conditions apply for at least SOC_RESET_TIME seconds:
;             * Lowest cell voltage is lower or equal to MIN_CELL_VOLTAGE
;             * Battery is discharging
;         - The calculated SOC is stored in dbus to persist a driver restart
;     False: Use SOC reported from BMS (none of the other parameters apply)
; More info: https://github.com/Louisvdw/dbus-serialbattery/pull/868
SOC_CALCULATION   = True
SOC_RESET_CURRENT = 2   
SOC_RESET_TIME    = 30
SOC_CALC_CURRENT_REPORTED_BY_BMS  = -300, 300
SOC_CALC_CURRENT_MEASURED_BY_USER = -300, 300
; Example to set small currents to zero
;     SOC_CALC_CURRENT_REPORTED_BY_BMS  = -300, -0.5, 0.5, 300
;     SOC_CALC_CURRENT_MEASURED_BY_USER = -300,    0,   0, 300

; --------- Externcal current sensor ---------
; Specify the dbus device and path where the external current sensor is connected to
; You can find it by executing the dbus-spy command
; Example for a external current sensor connected to the VE.Bus port:
;     EXTERNAL_CURRENT_SENSOR_DBUS_DEVICE = "com.victronenergy.vebus.ttyS3"
;     EXTERNAL_CURRENT_SENSOR_DBUS_PATH = "/Dc/0/Current"

EXTERNAL_CURRENT_SENSOR_DBUS_DEVICE = "com.victronenergy.battery.ttyS6" 
;smart shunt 1
EXTERNAL_CURRENT_SENSOR_DBUS_PATH = "/Dc/0/Current"

; --------- SOC reset voltage (needs to match BMS settings) ---------
; +++ This has nothing to do with "SOC calculation" in a section below +++
; 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
;     You also have to set CELL_VOLTAGES_WHILE_CHARGING accordingly, if you set CCCM_CV_ENABLE to true
;         else the charging current will be reduced to 0 before the target voltage is reached and the
;         battery will never switch to float
SOC_RESET_VOLTAGE = 3.650
; 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 =

Please remove the quotes from EXTERNAL_CURRENT_SENSOR_DBUS_DEVICE and EXTERNAL_CURRENT_SENSOR_DBUS_PATH. I wrongly inserted them in the example.

squowse commented 1 month ago

Thanks. The current display is closer to the Victron Connect App now. The VRM display still rounds to the nearest .1A though. Eg 1.40A compared to 1.46A on the app. Would this be expected?

The rounding doesn't seem particularly consistent eg down, nearest, up. The delay between readings could be confusing this though.

; --------- Externcal current sensor ---------
; Specify the dbus device and path where the external current sensor is connected to
; You can find it by executing the dbus-spy command
; Example for a external current sensor connected to the VE.Bus port:
;     EXTERNAL_CURRENT_SENSOR_DBUS_DEVICE = com.victronenergy.vebus.ttyS3
;     EXTERNAL_CURRENT_SENSOR_DBUS_PATH = /Dc/0/Current
EXTERNAL_CURRENT_SENSOR_DBUS_DEVICE = com.victronenergy.battery.ttyS6 
;smart shunt 1
EXTERNAL_CURRENT_SENSOR_DBUS_PATH = /Dc/0/Current

Please check with the dbus-spy or in the Remote Console/GUI.

squowse commented 1 month ago

The smartshunt current in Remote Console is rounded to 0.1A. The app shows to 0.01A image

squowse commented 1 month ago

dbus-spy also shows current rounded to 0.1A

mr-manuel commented 1 month ago

The rounding is normal, but how much is it delayed?

squowse commented 1 month ago

VRM? Maybe a second or two. Yes I think you are right - although the VE.Direct interface seems to get higher precision current measurements, the Cerbo only processes them at 0.1A. Thanks for your help with this

mr-manuel commented 1 month ago

But is there also a delay in the dbus-spy or Remote Console/GUI? If yes, how much?

squowse commented 1 month ago

No real delay between the app and dbus-spy or remote console. Half a second or less.
