I am working on integrating a battery energy storage system (BESS) with the OpenEMS framework and would like clarification regarding system monitoring and diagnostics. Specifically, is it possible for a BESS container, when managed via OpenEMS, to transmit or expose an End-of-Life (EOL) signal for one of its battery packs?
-
Is there native channel or custom device/component support in OpenEMS for such EOL signaling?
-
Can this EOL status (e.g., based on SOH thresholds, BMU/BMS alarms) be passed from the hardware (e.g., BMU/BMS) through OpenEMS channels to higher-level applications?
-
If not available by default, are there recommended approaches (custom channel, external API, Modbus mapping, etc.) for implementing this functionality?
Any guidance, examples, or pointers to relevant documentation would be greatly appreciated!
Thank you.
