[Request] AC charger: Implement DC/Battery stop SoC

[gitisgreat2023]

Is your feature request related to a problem? Please describe.

Currently stopping of the charging is defined by voltage. As both the start and stop threshold conditions are defined in SoC %s, adding a target to stop charging would make sense.

Describe the solution you'd like

Adding Battery SoC - Stop charging.

To avoid confusion: best rename
a) Battery SoC Stop threshold to Battery SoC - Stop discharging
b) Battery SoC - Start charging to Battery SoC - Allow discharging

Describe alternatives you've considered

Quick question for my understanding:
"Adding Battery SoC - Stop charging."

What are you using for charging?
Because as I understand, the VICTRON MPPTs are not receiving commands from OpenDTU (in order to stop charging)

[schlimmchen]

There is no "stop charging". There is only "start discharging", or in other words "start using the battery for energy production".

I don't understand what you are asking for.

What should happen if the newly proposed "Battery SoC - Stop charging" threshold is reached?

[schlimmchen]

Is this about the Huawei charger?

[gitisgreat2023]

Yes, after reaching the "Battery SoC - Stop charging" threshold it should stop charging...

Currently there are two SoC values: stop discharge, start again discharging. For example 15% (stop) and after reaching 20% allow discharging again.

The third value would be the upper level to stop charging, like 90% or 95%.

Yes my setup is a HM, Huawei, Pylontech setup.

I think this is completed with #848, which will be included in the next release.

Please re-open this issue if I got it wrong.
