TI and ST now are showing 14 and 16 cell BMS monitoring chips using transformers to isolate a SPI bus. They both show a daisy chain topology. Part numbers of interest are L9963 for ST BQ79600 and BQ79616 for TI. I wonder if Batman is one of these in disguise?
Hi Damien, Do you know where are the temperature readings on the slave BMS board? I am designing an energy storage system with tesla battery modules and a third party BMS and would like to know if I can get temperature readings from the battery cells?
Thank you for the work you do and sharing it. 😃 When, I saw your video in my feed. I was hoping the FPGA was working. But, It is nice to see something working. I want to put one of these in my RV.
I've not been following this, but is the batman chip just a protocol converter to the iso spi interface? If so what's to stop reimplementing it in a small FPGA?
@@Evbmw Would the files from 16.Oct on GitHub be your recommended version to connect my 4x M3-BMS in daisy chain and convert the data received into a RS485 CAN Bus?
Hello Sir. You are mentioning that you are having several Tesla model 3 battery module PCB delivered from a person in the US. I have removed a PCB now and having trouble reconnecting to the Ribon-cable on the module. Could you kindly ask you contact in the US how he is reconnecting to the module….. I have tried to solder on to the ribon but with no success….. I am desperate in need of help… Kind regards Simon, Denmark.
Good video with exciting progress. Sounds like you’re aiming to build in the bms balancing and limiting functionality rather than integrate with TDB’s simpbms? Am I getting that right
Really enjoyed you getting some progress on this project👍😀. For now you are just reading the voltages. When will you be able to activate the balancing side of th board?
How long is a piece of string. this requires alot of reverse engineering of the protocol, unless you got the documentation there is no telling if you will find out the required logic, let alone when.
Hey Damien. Cool stuff, I'm sure you have seen all the old EVTV stuff. It was hypothesised at the time that these parts were just LTC6813-1 parts, as they came out in a 64pin configuration not long after the model3 was released. Would be interested to know it you've already tried this same part. Cheers!
Awesome work! I've watched all your videos on the model 3 battery management systems, and applaud your determination! You mentioned that some people toss their BMB's because they use a whole different battery management system altogether. If I wanted to, say, directly get the model 3 module working with simp bms, what other components would I want to get? Or should I just wait and grab the new boards you're making, which should work work simp? Thanks!
Thanks:) This will work with simpbms once Tom gets the code done. I have sent him some parts for just that purpose : www.evbmw.com/index.php/evbmw-webshop/tesla-boards/tesla-model-3-bms-batman
You are so great, giving us super information that let us learn. Thank, thank thanks so much. From Mexico, your friend Gabriel Diaz del Castillo.

Been waiting for this one!
Also, I think it was "Swimming with bolegged women" but yes.

Am working on that with a spartan6. My verilog is lousy:)
It can be used as a protocol converter but it is also the actual bms chip for the slave boards.

Hello, great job Damien!
Do you know pitch size of this BMS board connector? Is it FPC 1mm or any bigger?

Are you planning to look at the model 3 charger eventually?

Great work!
Only one audio channel though, hard to listen to with earphones :)
I though I was becoming deaf xD.
With iPhone you can turn mono-sound on to get the one channel on both ears.
This guys gettin er done
So you have been Robin Batman!
Great video
👌👍👏👏
apparently he said "swimmin'" not drinking
Sam Quint, not Ned.
