How does PLC communication protocol work in M560 & M580?

M560 and M580 hardware is designed to support different charge control interfaces such as J1772, CHAdeMO and GB/T. Both AC and DC charging can be supported by this ECU, however the OpenECU platform software currently only supports DIN SPEC 70121:2014-12 for DC charging.

The ECU supports a QCA chipset for implementing the Home Plug power line communication (PLC) standard. DOT enable QCA needs to be set high to enable power for the QCA.

We have put together a document that fully describes the functionality of PLC protocol in M560 and M580 - https://www.openecu.com/wp-content/uploads/2020/07/CCS_Charging_Communication_Explanation.pdf
