Seplos V3.0 BMS Multi Pack #112

DpunktS · 2024-10-01T19:06:42Z

Hallo,

ich habe mein Seplos V3.0 BMS mit einem 2. BMS aufgerüstet (Multi Pack). Leider bekomme ich sehr viele CRC Fehler für das 2. BMS und somit keine vernünftigen Sensorwerte.

[20:52:04][W][modbus:114]: Modbus CRC Check failed! 9E67!=100
[20:52:04][W][modbus:114]: Modbus CRC Check failed! 31C2!=E8

Wie kann ich meinen Speicher weiterhin auslesen?

Wie genau sieht deine YAML-Konfiguration aus? Wie häufig fragst du die Geräte nach neuen Werten?

DpunktS · 2024-10-01T21:33:08Z

Im Grunde ist es deine Standard YAML für den ESP32 mit allem Werten und 10s intervall.

Mir ist auch aufgefallen wenn ich meinen selbst gebauten RS485 USB Adapter verwende erreiche ich mit dem Laptop das erst BMS nicht, das 2. BMS hat angeblich die Adresse 3 und der Wechselrichter hat keine Kommunikation zum BMS mehr. Laut Seplos Anleitung hat die RJ45 Buchse noch 2 Adressierungspins (4,5). Ich habe mir jetzt nochmal den originalen Adapter bestellt zum testen.

Einzeln hat mein Setup bis jetzt fehlerfrei funktioniert und auch die Kommunikation zwischen den beiden BMSs funktioniert.

Ich glaube, die Lösung für mein Problem ist dieser Lösungsansatz #80

Leider wurde die YAML nicht mit den Zellspannungen vervollständigt.

Ich habe es jetzt geschafft, meine 2 Speicher auszulesen. Es wäre schön, wenn ihr es in euer Projekt aufnehmen könntet, weil ESPHome bald die Unterstützung für "Custom Sensor Component" einstellt.

jolly12f · 2024-10-11T17:13:47Z

could you make a guide on the work to be done?

DpunktS · 2024-10-11T21:17:16Z

Du musst den ersten Code als seplos_v3_sniffer.h speichern und an den selben Ort der ESPHome YAML schieben.

Der 2. Code ist die Konfiguration für ESPHome die du wie gehabt bearbeitest.

Ich meinem Beispiel ist keine CRC Prüfung eingebaut weshalb ab und zu mal ein falscher Wert auftaucht.

sunnysingh-84 · 2024-10-12T10:16:29Z

I attempted this and got the following error when installing:

INFO ESPHome 2024.9.2
INFO Reading configuration /config/esphome/seplos-bms.yaml...
Failed config

esphome: [source /config/esphome/seplos-bms.yaml:6]

Der Fehler sagt, dass er die Datei nicht an den angegebenen Speicherort findet.

Alexandros89 · 2024-11-10T21:09:32Z

Ho provato a farlo e ho ricevuto il seguente errore durante l'installazione:

INFO ESPHome 2024.9.2 INFO Lettura configurazione /config/esphome/seplos-bms.yaml... Configurazione non riuscita

esphome: [sorgente /config/esphome/seplos-bms.yaml:6]

'name' è un'opzione obbligatoria per [esphome]. Comprende: - ./seplos_v3_sniffer.h

the point should be the name of the esphome path

Hi! I'm using the sniffer and it works fantastic for up to two batteries. I have 4 batteries set up and get sometimes weird values for voltages and temperatures in 3rd battery. On 4th battery I get those weird values most of the time. There I read mostly 4000 degrees battery temperature. If I modify the code to read only 4th battery the issues remain the same. What could be wrong there? Does anyone else have more than 2 batteries in their setup?

DpunktS · 2024-11-19T20:24:00Z

Es ist möglich das dein Bus leicht gestört ist und die fehlende CRC-Prüfung es nicht filtert. Oder du hast bei der Erweiterung einen Fehler gemacht. Vielleicht ist auch der Nachrichten Puffer (rx_buffer_size: 1024) zu klein. Weil 2 Akkus haben schon 266 bytes.

Thanks for fast reponse. I suppose if i had a typo in code, there would be false readings all the time. Tried wirh rx buffer 2048 and also with two separate esp32 and each having separate rs485 converter for each pack pair but the result is same. Always 3rd and 4th pack readings fail. Even if i just try to read 4th pack, I get these wierd values.
Below You can see how different pack current reults are received.

What else could I do? Is it possible I miss something in .h file code except battery address?

DpunktS · 2024-11-20T05:13:36Z

So wie ich das sehe sind das nur vereinzelte falsche Wert die die CRC-Prüfung filtern würde. Die Akkus senden alles 200ms ihren Status somit fallen ein paar gefilterte Wert nicht auf.

Ich werde es als Laie mal versuchen eine CRC-Prüfung zu integrieren :). Oder vielleicht bekommst du das schneller hin. Es müsste von diesem Projekt https://github.com/ferelarg/Seplos3MQTT auf ESPHome angepasst werden.

nammto · 2024-11-20T05:57:19Z

:-) I don't think my knowledge reached that far to do it.

DpunktS · 2024-11-20T08:41:15Z

Probiere mal bitte diesen Sniffer mit CRC Prüfung
seplos_v3_sniffer.zip

nammto · 2024-11-20T17:59:46Z

Got home to test it. I'm now with Your CRC code able to read pack 1&2 data, also pack 3&4 data if I read only 2 packs at a time. If I try to read all 4 packs, I get only data for pack 3 and 4.
Edit: I forgot to add battery pack addresses in first address if statement :-D
Now works like charm. Huge thanks for that!

DpunktS · 2024-11-20T20:06:50Z

@nammto wie hast du diese Zeile für den 3 . und 4. Akku geändert?
if (!((bytes[0] == 0x02 && bytes[1] == 0x04 && (bytes[2] == 0x24 || bytes[2] == 0x34)) || (bytes[0] == 0x01 && bytes[1] == 0x04 && (bytes[2] == 0x24 || bytes[2] == 0x34)))) {

This is for all 4 packs: if (!((bytes[0] == 0x02 && bytes[1] == 0x04 && (bytes[2] == 0x24 || bytes[2] == 0x34)) || (bytes[0] == 0x01 && bytes[1] == 0x04 && (bytes[2] == 0x24 || bytes[2] == 0x34)) || (bytes[0] == 0x03 && bytes[1] == 0x04 && (bytes[2] == 0x24 || bytes[2] == 0x34)) || (bytes[0] == 0x04 && bytes[1] == 0x04 && (bytes[2] == 0x24 || bytes[2] == 0x34)))) {

@nammto probierst du diesen seplos_v3_sniffer bitte mit deinen 4 Akkus aus. Mit meinen 2 Akkus funktioniert es gut.

nammto · 2024-12-18T18:00:42Z

@DpunktS Working like charm out of the box. Just need to add the declarations for the rest of the BMSs in YAML file.
Few errors i've found in .cpp file:

remaining capacity is showing 10 times less than actual (found it just now, that same issue also in old .h file), so just *10 must be added in variable calculation.
only in new version, maxdiscurt and maxchgcurt are showing 100 times lower values than actual. (You have /100 in Yout code, take it away)
Excellent work! If You add now automatic variable declaration according to discovered BMSs, it will be a full product plug'n play. If You don't configure more than two BMSs in YAML, then it will say in LOG, that found something also on address 3 and 4.

DpunktS · 2024-12-19T21:38:33Z

Ich danke dir für dein Lob. :)
Die Fehler habe ich korrigiert. Dein Vorschlag mit den automatischen anlegen der Sensoren wollte ich auch realisieren leider ist mit kein weg bekannt den ESPHome unterstützt.

tugsi · 2024-12-20T12:53:04Z

@DpunktS Kleine Frage am Rande, hast Du zusätzlich den CAN am Wechselrichter angeschlossen?
Mir ist noch nicht so ganz klar, ob das geht, also CAN am (in meinem Fall) Victron und gleichzeitig mit Deiner Lösung alles per RS485 auslesen.
Finde SEPLOS irgendwie konfus, habe zwei Packs mit V3 parallel angeschlossen und zack ist einer per Bluetooth nicht mehr erreichbar, der andere ja.
Deswegen würde ich auch gerne mehr Infos auslesen im Betrieb.

DpunktS · 2024-12-20T13:15:15Z

Ja meine 2 Seplos V3 sind per CAN am Wechselrichter angeschlossen. Zum Verständnis bei Modbus RS485 kann es nur einen Master geben und das ist bei mehreren Akkus immer bms0 also, der wo CAN angeschlossen ist. Deswegen ist auch nur noch der Master per Bluetooth erreichbar. Der ESP mit den bisherigen Projekten würde auch wieder ein Master sein und deswegen funktioniert die Kommunikation ab 2 Akkus nicht mehr. Meine Lösung liest nur die Kommunikation zwischen Master und Slave's mit und wertet diese aus.

tugsi · 2024-12-20T15:18:32Z

Danke für die Rückmeldung. Das Verständnis Modbus habe ich (hab beruflich mit Bus-Systemen zu tun, u.a. auch Modbus). Mir war nur nicht klar, ob gleichzeitig dann noch CAN sauber funktioniert, da in diversen Foren auch vieles widersprüchliche liest. Und dann kommt noch Seplos V3 oder alt etc.
Dann schau ich mal, wann ich Zeit dazu finde und baue mir das mal nach. Danke Dir.

tugsi · 2024-12-28T12:30:30Z

@DpunktS Nur zum Verständnis, hast Du zwischen dem ESP und dem Seplos noch ein RS485-TTL-Wandler dazwischen und wenn ja welchen?

DpunktS · 2024-12-28T13:53:06Z

Ich habe diesen Konverter verwendet. Es kann aber jeder ttl rs485 Konverter verwendet werden.

tugsi · 2024-12-28T14:04:41Z

Danke, ich dachte ich hatte noch einen, aber leider nicht.
Genau den Typ hab ich gerade bei Ali bestellt 10Stck für knapp über 5€, dann hat man Reserve ;-)

syssi · 2024-12-28T14:27:09Z

Je nach Konverter ist manuelle Flusskontrolle über einen zusätzlichen GPIO notwendig. Das obige Modul kommt ohne diese Fusskontrolle aus, deshalb nutze ich es lieber.
