EV Charging Station NS (EVCS NS), Modbus, Register? What do they do?!

Hey,

I've already asked in the German-speaking area, but unfortunately I haven't received an answer yet. :-(

So, here in English:

I've had an "EV Charging Station NS" in my Victron setting for a few days.

I control the entire system with IP Symcon and Modbus. I have already converted the EVCS to switch between 1 - 3 phases. (official modification)

There are some parameters in the Modbus Excel list that I don't understand. - Currently I am not satisfied with the steps (increasing / decreasing the charging power of the speed it changes these values of the EV charger). Sometimes it moves up too quickly and then has to reduce the power again sharply.

I would like to optimize the steps and timing.
Can someone please help and explain the following parameters?


5057 Power for 3phase uint16 1 to 65535 4800 R/W yes W. Related to 'multiple relay charging' feature.
5058 Power for single phase uint16 1 to 65535 4300 R/W yes W. Related to 'multiple relay charging' feature.
5059 Phase switching timeout uint16 1 to 65535 60 R/W yes s. Related to 'multiple relay charging' feature.


5068 Backup battery emulation uint16 0 to 1 0 R/W yes 0 - disabled, 1 - enabled
5069 'Feed in'. Start delay uint16 1 to 65535 30 R/W yes s
5070 'Feed in'. Stop delay uint16 1 to 65535 60 R/W yes s
5071 'Feed in'. Single phase. Grid power for start int16 -32768 to +32767 -500 R/W yes W
5072 'Feed in'. Multi phase. Grid power for start int16 -32768 to +32767 -1400 R/W yes W
5073 'Feed in'. Grid power threshold for increase int16 -32768 to +32767 -250 R/W yes W
5074 'Feed in'. Grid power threshold for decrease int16 -32768 to +32767 250 R/W yes W
5075 'Feed in'. Backup battery discharging power threshold int16 -32768 to +32767 -100 R/W yes W
5076 'Feed in'. Current step uint16 1 to 65535 2 R/W yes A*10
5077 'Feed in'. Time step uint16 1 to 65535 1000 R/W yes ms
5078 'Battery powered'. Start delay min uint16 1 to 65535 30 R/W yes s
5079 'Battery powered'. Stop delay uint16 1 to 65535 60 R/W yes s
5080 'Battery powered'. Start abort delay uint16 1 to 65535 10 R/W yes s
5081 'Battery powered'. BKPB balance power uint16 0 to 65535 500 R/W yes W
5082 'Battery powered'. BKPB balance SOC max uint16 1 - 100 98 R/W yes %
5083 'Battery powered'. Available sun power threshold for start uint16 0 to 65535 100 R/W yes W
5084 'Battery powered'. Grid power threshold for start uint16 0 to 65535 25 R/W yes W
5085 'Battery powered'. BKPB power threshold for decrease uint16 1 to 65535 250 R/W yes W
5086 'Battery powered'. Grid power threshold for decrease uint16 1 to 65535 250 R/W yes W
5087 'Battery powered'. Discharging detect timeout uint16 1 to 65535 7 R/W yes s
5088 'Battery powered'. Next try timeout for increase uint16 1 to 65535 45 R/W yes s
5089 'Battery powered'. Time step uint16 1 to 65535 15 R/W yes s
5090 'Battery powered'. Current step uint16 1 to 65535 10 R/W yes A*10
5091 'Battery powered'. Grid power for 'feed in' detection int16 -32768 to -1 -100 R/W yes W
5092 'Battery powered'. Start delay max uint16 1 to 65535 180 R/W yes s
5093 ON grid detection threshold uint16 0 to 65535 0 R/W yes W


What exactly is "Feed in" and "Battery powered"?
I hope someone can help me.

Thank you, Martin
