Which protocol does the Victron EV chargers use?

Good afternoon,


currently I search for Infos how to build/design an AC/DC combined EV charging station Type 2 with 230V/32A/7kW . However, the DC part is ELV (Extra Low Voltage) with 24V/80A/2kW or 48V/80A/4kW.


I like to know, which protocol the Victron EV Charger use, to communicate to the EV.


I consider using the OCPI v2.2.1 or the newer under development 3.0.0.


Thanks for your help

None, OCPP will be added later. For now, it can be controlled externally over Modbus TCP

Hmmm, OCPP does not support the V2G charging if I am right.

Is there a document for the Modbus protocol used in the EV charging station?


I have already experimented with the VE.Direct protocol and a Banana PI Zero to get my own wind charger in Victron integrated.


Now I want to do this with an OEM EV charging electronic 230V/32A which just cost me 138€ including shipping from China. However, it has a RS485 communication port. ;-)

Thankyou


However, I got today per Post a EVCS for testing but it seems, the WIFI does not work trough 40cm thick Log-Wall.. The distance between the WiFi Ap and the Charger in the garage is only 12m.

It seems, I have to wait until an Ethernet version is availlable.
