Charging state binary_sensor

[tolwi]

          May I ask you also to add sensor or binary_sensor for charging state?

Got it:
"bms_emsStatus.chgState": 1, 1 - is charging, 0 - is not charging internal battery.

So far I have written an automation in which I determine the fact of the charging using of the charging remaining time sensor state != 0
😀
