1 year ago Hello @alperkan,
Thanks much for posting the logs. I may be missing the documentation or examples elsewhere, but how did you adapt the iso15118 library to communicate with/control a Power Line Communications chip (e.g. the Qualcomm QCA700x)?
Cheers, Hal

Hi, @gh4emb,
I made my own microcontroller circuit for CP signal and detecting car states. I modified a QCA7420 bassed TP-Link PLC adapter for PLC and raspberry pi 4. On raspi I used open plc tools for SLAC and this library for UDP/TCP communication.

1 year ago Hi @alperkan , Thank you for sharing these logs. I think the following entries are of interest in the logs above:

INFO 2022-12-17 10:26:18,987 - iso15118.shared.comm_session (234): SessionStopReq receivedThere seems to be ~5.4 seconds between CableCheckRes being sent and SessionStopReq being received. As the timeout for CableCheckRes at the EV end is 1.5 seconds, perhaps the message was received at the EV end after the timeout and hence the SessionStopReq? Was this behaviour consistent between tests with Seres3 though? If you still have access to the EV, would it be possible to get a pcap file to see the exact time the message was sent from the SECC end?

1 year ago hi, @shalinnijel2 Thanks for your reply, Seres 3 is my own vehicle. I have no problem with access. Now I made a new try. I listened to the network with Wireshark. Below you can find the terminal logs and pkapng file of the new experiment.
As you said, EV does not detect the cableCheckres message we send after the cableCheckreq saying I am ready.
I tried different changes by changing NotificationMaxDelay to 0, 100, 200 and 500. When I did 500, there was no response from EV for a while, then the EVSE code gave a timeout error. When I tried the others, nothing different from the first case happened.

WARNING 2023-01-06 11:37:46,104 - iso15118.secc.transport.tcp_server (124): Closing TCP serverHi @alperkan Thank you for the pcap files and the logs. EVRESSSOC (state of charge) is being reported as 0 in CableCheckReq and ChargeParameterDiscoveryReq. Is that true?
As your EV supports 15118-2 as well, could we try that too, please? And we could perhaps compare behaviour? From the supportedAppProtocolReq messsage, the EV prefers DINSPEC over 15118-2. So we will have to force SECC to offer only 15118-2 - this could be done by setting the following variable in the .env file and restarting the service.
PROTOCOLS=ISO_15118_2If set correctly, this would be reflected in the env settings logged when SECC comes up.
Kind regards, Shalin.

1 year ago Hi @shalinnijel2 Yes you are right, EV sends SOC as 0, I hope it will fix it with precharge.req. The EV also supports the 15118-2 as you said. I made the change you mentioned in the .env file, but it was still connected via DIN70121. I also made a change to the secc_settings python file.
default_protocols = [
"DIN_SPEC_70121",
"ISO_15118_2",
"ISO_15118_20_AC",
"ISO_15118_20_DC",
]I removed all but ISO_15118_2 in this section and managed to communicate with the 15118-2 protocol. The result is that the CableCheck.req request is no longer coming. :) You can find the new logs and pcap file below.

Hi I tried the code with 2 different cars. I got stuck in many places and overcame them by reasoning and making small value changes in code. One of the vehicles is the Peugeot e2008 and the other is the Seres 3.
I was able to reach the Precharge request and response sections with the Peugeot tool. Since I don't have a power source to provide the 395 V 2A the car requires for pre-charge, the request-response cycle continues at this stage and this is very normal.
The problem is that Seres3 sends session stop request instead of Precharge request after wire check status. I have tried changing many values in the simulation.py file but the result is always the same.
Below are the logs I got from the terminal screen. Peugeot switches to Precharge phase even if the charging parameters are incorrect. I could not understand why the Seres3 model vehicle terminated the session. Normally, the vehicle can be charged at DC charging stations without any problems.
Logs from Peugeot e2008 session:
