I'm trying to explain my issue.
My operating mode is permanently set to Scheduled.
I have configured four time periods:
00:00 – 08:00
Minimum SoC: 20%
Maximum SoC: 100%
08:01 – 15:00
Minimum SoC: 50%
Maximum SoC: 100%
15:01 – 18:00
Minimum SoC: 90%
Maximum SoC: 100%
18:01 – 23:59
Minimum SoC: 20%
Maximum SoC: 100%
Under Quick Settings → Battery Control, I currently have the following values configured:
Battery SoC: 75% (Min) – 100% (Max)
Off-Grid Minimum SoC: 20%
Now let me explain why I configured it this way and what my question is.
My goal is to charge the battery during the day, roughly between 08:00 and 18:00. However, whenever my EV is charging at the same time, the system always drains the battery down to 20%, even when the EV is charging in surplus charging mode.
To prevent this, I increased the scheduled Minimum SoC to 50% during the day and to 90% from 15:00 onwards, so that enough battery capacity is reserved for the evening.
However, I have now noticed that it doesn't seem to matter what values I configure for the individual scheduled time periods. The system always follows the Battery Control settings instead.
For example:
If I set 20%–100% in Battery Control, the battery is discharged down to 20% at any time of the day.
If I set 75%–100%, the battery is never discharged below 75%, regardless of the scheduled periods.
The second option is not what I want because during the night I actually want the battery to be allowed to discharge down to 20%.
Am I really expected to manually change the Battery Control settings several times a day depending on the time? Or am I misunderstanding how the Scheduled mode is supposed to work?
I hope I explained my issue clearly enough.
