Zellspannungen bei zwei Akkupacks loggen #27

Closed RRonGit closed 3 months ago

RRonGit commented 3 months ago

Describe the problem

Hallo Zusammen,

Ich habe folgende Umgebung:

Raspi4 mit VenusOS Verion v3.30 2x Seplos Batteriepacks BMS Seplos BMS V16 (10E) Software Version: 16.6 venus-os_dbus-serialbattery von mr-manuel installiert Version: 1.1.20240121 BatteryAggregator installiert via Setup Helper Version: v3.0.20

Die Seplos BMS sind beide separat per USB to RS485 an den Rapsi angeschlossen.

Das Ganze funktioniert soweit.

Gerne möchte ich aber die einzelnen Zellspannungen loggen.

Mit einem BMS geht das via Node-RED problemlos. Bei zwei BMS werden die Werte immer abwechselnd von den beiden BMSen angezeigt.

Config file

[DEFAULT]

; 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):
; --------- Battery Current limits ---------

MAX_BATTERY_CHARGE_CURRENT = 140.0
MAX_BATTERY_DISCHARGE_CURRENT = 195.0

; --------- 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   = 3.062
; Max voltage (can seen as absorption voltage)
MAX_CELL_VOLTAGE   = 3.531
; Float voltage (can be seen as resting voltage)
FLOAT_CELL_VOLTAGE = 3.375

; --------- Temperature limitation (affecting CCL/DCL) ---------
; Description: Maximal charge / discharge current will be in-/decreased depending on temperature
; Example: The temperature limit will be monitored to control the currents. If there are two temperature senors,
;          then the worst case will be calculated and the more secure lower current will be set.
; Charge current control management referring to temperature enable (True/False).

; 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

Please install the latest dev and the problem should be shown. Probably your batteries have the same VRM ID.

RRonGit commented 3 months ago

@mr-manuel, thank you very much, it worked. I have now installed version 1.2.20240404dev. Then I had to change the capacity of a battery from 280Ah to 281Ah so that the batteries got different IDs. Now I can log the two batteries separately.
