Does this support IEC 61851-24 and ISO/IEC 15118

Does this allow to modify for dc fast charging using R4875G2 CAN-BUS-control-R4875G1-with-ESPHome-and-MQTT
im trying to design a fast charger based on the above open source pdf and the huawei R4875G2 which allows voltage and current control over can.
if im not wrong it has a superimposed high level communication mentioned as below:
7 COMMUNICATIONS
7.1 Digital Communication Between the EV Supply
Equipment and the EV
Digital communication is optional for Modes 1, 2
and 3.
For Mode 4 the digital communication as described in
IEC 61851-24, shall be provided to allow the EV to
control the EV supply equipment.
NOTE — Digital communication as described in ISO/IEC
15118 series is also called high level communication.

Hi,
This project is based on the SAE J1772 specification, which look like IS 17017 as you send.
ISO 15118, which uses digital power-line communication and uses the entire TCP-IP stack, so completely different hardware would be needed.

I haven't dealt with V2G yet, because:
The first problem is that ISO 15118 is not freely downloadable.
EV manufacturers are still not uniform in implementation.

So, I'm not thinking about it in the roadmap yet :)

The first problem is that ISO 15118 is not freely downloadable.

Let me know if this is still an issue for you.

Thanks, but I don't have the space for this yet :)
I should probably focus on OCPP or new ESP-S3 board desing...

the red beet itself is just a powerline modem. It needs to implement the full charging communication stack (ISO15118). Afaik there is no open source esp32-compatible implementation. Only some in python which could be run on a raspberry pi or similar.
there is the "white beet" variant, which comes with an embedded charging stack.
