Ich hatte folgende Fragen an den Deye Support:
Kann ich BOS-G Akkus einzeln mit dem Wechselrichter laden?
Welches Ladegerät brauche ich um BOS-G Akkus zu laden?
Die Antwort:
Sorry, this requires consulting the battery dealer, they will get back to you
Beim Batterie Händler hatte ich vorher schon angefragt, aber keine Antwort bekommen.
Vielleicht hat ja hier jemand eine Antwort auf meine Fragen.
No you can't.
You will need a power supply that is capable of outputting at least 60V to charge individual battery packs.
Hello, how do I have to charge one battery? What‘s the charging voltage and charging current? Do the battery protect itself against to high voltage and over loading?
Best regards Markus👍
If you manually charge indivitual BOS-G pack you have to charge it up to ~57V max.
Each pack is 16S LFP configuration, and max voltage of each cell is ~3.6V, 16*3.6V = 57,6V.
I think each pack should have its own BMS and protection, but I'm not 100% sure.
In reality, if you charge to ~55V you will reach very close to 100% SOC, due to very steep voltage curve of the LFP cells, the voltages above 55V store almost no energy.
Thanks, I‘ll try to charge until 55V.
But I realized that the first battery pack reaches within 10min the 55V and I stopped until the current reaches 100mA. After that I realized that the voltage of that block (nothing connected) falls within 5min to 54V, is that ok?
Yes, that is normal.
