So I figured I'd better start a subforum and put in a placeholder for Ipace parts hacking. From a 2020 vehicle. Have a front motor and inverter and quite a bit more that I don't know:)

You're the DIY EV equivalent of the guy who's on a date with 2 different women at the same time, and then when a girl at the bar flashes him a smile he takes time to chat her up and get her number too.
Just when we were all settling down to CAN along comes FlexRay! Wheeeeee

Ugh. Too rich for my blood.
Interestingly, Comma.ai built a board using an FPGA to intercept steering FlexRay...they also acknowledged it was a giant hack and still have no further support for the vehicle: https://medium.com/@comma_ai/hacking-an ... 10b1d29f3f

Ugh, Volvo changed to FlexRay a few years ago as well. Why use a perfectly good standard when you can make it WAY more complicated.

Interesting article on comma.ai. Most useful is they opensourced a flexray decode for the Saleae and published the fpga design. That said, I feel a replacement logic board coming on. This automotive stuff is funny. Nothing in a car that can't be handled by CAN or even good old RS485 and yet we see crap like this....

Damien, NO! You dont want to do anything without Jaguar BMS!
Seriously, i have a complete BMS from my battery here. If you want to go for it or have too much time on your hands, or there are three of you cloned etc... i can donate it to you since i have my own solution for BMS . I also have a complete harness from Battery to BMS and some of it towards the outside.
PM me if you want it.

......NO.........must resist.........
Johannes : "I can do FOC with an STM32F103 and lots of other stuff"
Auto Industry : "We can do FOC and weird comms with a quad core....oh wait"

We're in....
anyone want to help find that mystery psu control ic .... ?
edit : is it me or do FPGAs have the coolest names? Cyclone IV , Spartan 6 ....

LOL are they doing angular processing in the FPGA? (MoTeC does this for engines)
The TriCore can do quite a bit too.
Wow, so, yeah that's...really, really overkill.

Electric motor control hasn't evolved that much in 3 decades, yet they keep throwing more hardware at it
I'm more impressed by the mechanical and power electronics design.

_OH_
Continental. That makes so much sense now. They love their TriCore. Probably same engineers as the Engine Control.
The hardware does look good, and pretty compact.

We should be glad they make big boards, and not tiny boards that is normal in almost any other product.

Cool name on the board to "Continental"?

But Johannes! How else will they keep up with a dual 10Mbps flexray comms bus .........oh wait....

It might be worth measuring up the flexi ribbon cable to see if it's simply a standard FFC, Flat Flex Cable format.
These cable ends come in standard sizes with different types of zero insertion force connector available and each with different orientations that will all fit the same cable ends.

Thanks to a youtube comment we now know the inverter is made by a German company called Vitesco for several different oems.
From memory them pins are called compliant pins, claim to be better than soldering as the allow for expansion etc...
Have seen them fain on Bmw air bag satellite sensors, where the housing / connector had 3 compliant pins for the connections and the pcb was a push fit.
I'm not sure the pitch of your connector but if the are at 0.1 inch pitch you should be able to put a samtech connector on the new top board and solder long pins into the bottom board.

Need to measure your hvdc with 16 bit accuracy and 10MHZ clock speed? Of course you can with the new AMC1305 from Texas Instruments.
