Hi @Joenoodoe ,
have you changed the default configuration of EV and EVSE? In this case, can you please provide your changes to the sources as a patch file.
What I have seen is that you set the battery capacity to -15536Wh. The exponential value is a signed short and c3 50 00
is a negative value. If you want to set the battery capacity to 50kWh use 50 for the value and 3 for the exponent: 00 32 03
.

Hi @jpo-stx

No, we didn't changed the default configurations of EV and EVSE.

After modify the code for changing the battery capacity( Payload: 0xc4, 0x93, 0x0, 0x21, 0x55, 0xc5, 0x2, 0x0, 0x1, 0x1, 0x0, 0x1, 0x0, 0x0, 0x32, 0x3), the error still show up. Trace the document and EV code
a. Tracing the document I found that: EV -> Set configuration command
The document shows two byte value (C3 50) which is different from you said. Which is the real value we need to send ?b. Tracing the code I found that: EV -> Whitebeet.py -> Set configuration command
The code didn't caculate the exponent value. Have the code been test already ?if isinstance(config["battery_capacity"], int): payload += config["battery_capacity"].to_bytes(2, "big") payload += b"\x00" else: payload += config["battery_capacity"][0].to_bytes(2, "big") payload += config["battery_capacity"][1].to_bytes(1, "big")

Currently, we just want to test the whole procedures including CP, SLAC and V2G using Ethernet. Could you provide the working code for each module-EI and module-PI ?

Hi @Joenoodoe , my collegue is currently analysing the issue. I will come back to you with the results
from freev2g.
In the meantime, can you update your EVSE to the latest firmware version V01_01_06 from december 2021.

Hi @jpo-stx,
We test the whole procedures successfully between module-EI and module-PI after modifying both code.
This issue can be closed for sure.
If we have problems, we'll open another issue in github.
Thanks for help and analyzing.

@Joenoodoe nice to hear that you could could solve the issue.
Nevertheless, we will update FreeV2G so that it is working out of the box. Sorry for the inconvenience.
