I also find that SOC can be read out in reg 0x358 0 byte.
case 0x358:
battery_soc = rx_frame.data.u8[0];

0-100 in decimals. No need for scaling.
But I found out that SOC is "frozen" will not move even if the battery is cycled up and down, which confirms my suspicion that some kind of ...

You need to make sure or HVIL and other hardware related signals are satisfied - would be good to check those on the car.

I use socketcan devices on Linux + SavvyCAN for that

ive also just brought the same pack... as per the thread ive got it spiting out can codes and can work out soc, voltages,temps etc but would like to know (if it is in fact known) the balancing of pack whever its auto or a can instruction and can code to close /open the contactors?


Having a ...

I'll keep updating my findings


Did play a little with your canbus data:

0x010: is not present in the disconnected battery log
0xF0 and 0xF2: are not present in ...

All pictures are available at the google drive resources provided by opelmantra.

Yes

How it's going I'm considering buying one

Hello, I have got a whole MEB-ID3 Battery-System with 9 Modules, 2x4Port and 1x1Port MCM-BMS-Slaves, the Power-Switching-Sector and some connection-stuff and cables. All components were connected by CAN-Bus together.
I haven't investigated the contactor-section yet, therefore now my question ...

Sure thing about support - Happy New Year !

Tom it looks like Teensy 3.2 is RIP - do you mind if I'll start porting job of your code to Teensy 4.0 (via GitHub fork) and base new PCB on your old design?
(Teensy 4.0 pins are only 3.3V capable)

Happy New Year !

I think no longer available but I was able to source 5 of them 2 months ago.

I have found SimpBMS clone on TaoBao - half price - anyone interested let me know.

CHAdeMO is way easier to implement (just CAN) compared to CCS that needs some PLC device (more expensive?) and full TCP stack AFAIK.

Looks like this one has so less components - I'm using JLC for at least a year now - they've been great so far. Good choice.

It looks like Damien is too busy to update github at the moment

Finally, I see v5 of Tesla Gen2 charger will ditch this expensive hard to get microcontroller in favour of STM32 - great move. Are you going to publish those on your github? Did you also choose USB-C? Also battery connector - so we'll be able to have charging times table? Cool!

Setting up a support thread for the open source Tesla Charger controllers.
Will cover both Gen 2 and Gen 3.
