Vecan Bms canbus dbc file/datasheet

Hi All,

Does anyone have a dbc file or even a datasheet for the canbus messages required for BMS into a gx device. I know what can id’s the Fogstar batteries are sending in as I have analysed the output from one of there batteries. I can decode some of the messages but it would be a lot quicker if there was a dbc file or datasheet giving me all the information that Victron can receive?

Victron does not publish their spec to the public. Interested manufacturers can request access from their regional sales manager.
As a community we can’t share that data, though some of it is wafting around the internet if you search.

I found some info but not all of it. I’ll ask the local dealer to request the information

Is this enough?
If not, what do you need more?

The minimum CAN-IDs required for the core functionality are 0x351, 0x355, 0x356 and 0x35A.

Thank you for that, there is a fair bit of conflicting information out there. I have can inspected the Fogstar batteries I use with the protocol on Victron and some id’s differ. The main ones above are the same but the pylon datasheet is different to what I’m getting but maybe that’s out of date.

Please tell about your conflicting info to see if I can shed some light…

Below are the can id’s out of the fogstar battery, pylontech talk about a 0x359 which is for protection and modules numbers but that’s not coming out of the Fogstar but still getting the protection and modules number messages on the gx device.

Latest I could find…
Both infos were posted by the respective manufacturers on the web, but later withdrawn.
Thanks to Wayback Machine, here they are, at year 2021 level.
Victron BMS info.
Pylontech BMS info.

That is ideal. Thank you

pls. have a look into Stuart Pittaway’s “diyBMS”. BTW it’s worse having a look into the whole open source HW and SW by Stuard.

Or send me an email (bk-ve@gmx.de) with your github user and I point you to some more open-source projects.
