Ja - manchmal Brelslau gehört zu Deutschland... aber jetzt nicht
I will gladly answer your questions:
- Kostenpunkt (Preis)? Price is depending on chosen model (type of user interface, number of cells, maximum current,...). Write me an e-mail and I will send you an offer.
- Werden die Einzelzellen überwacht oder immer nur mehrere Blöcke? Every single cell is watched (voltage). Every measuring module is able to control 10 cells and 1 temperature sensor.
Maesuring modules are connected to main module (computer) and screen.
- Was wird überwacht? Überspannung? Unterspannung? Overvoltage, undervoltage, overcurrent, temperature, ...
- Was werden für Alarme ausgegeben?
- Wie werden die Alarme ausgegeben? (Optokoppler, Relais, Bildschirm?) There are sound signals and signals on the lcd screen. Also there are connectors (plugs) on the main unit that can be used to inform with diodes or realys.
- Erfolgt ein Zellbalancing? BMS systems we offer now do not contain active balancing functionality. Basing on our experience and information from battery manufacturers - LiFePO4 cells can ba also successfully used without active balancing.
We are negotiating now with new BMS and charger manufacturer and in some time we will offer also this fuctionality. Anyway - we have to test it first ourselves.
- Was wird anzeigt? Spannung? Strom? Temperaturen? Amperestunden? Voltage, current, capacity left in battery pack, max Voltage of single cell (and cell number), min Voltage of single cell (and cell number), max temperature from sensors
If you will have any questions - just let me know.
Best regards,
Rafal
