I have the zombieverter and dilithium mcu bms in my car working together. See my github https://github.com/Wim426F/Stm32-vcu.
DilithiumMCU.cpp. It reads the stats from the MCU over can via RPDO and TPDO. Including the GFM (ground fault monitor) signals as well.
Unrelated to this but I also have ...

I was able to test the new digipot on hardware V2 in the car with this change to the software:
void DigiPot::SetPot1Step() {
DigIo::pot1_cs.Clear();
spi_xfer(SPI3, 0x00); // channel 0
spi_xfer(SPI3, Param::GetInt(Param::DigiPot1Step));
DigIo::pot1_cs.Set();
}

void DigiPot::SetPot2Step ...

Thanks, I had overlooked that.
Why is output 50 to 400 Ohm? the old digitalpot had 10k/256 steps is 39Ohm/step. and the fuelGaugeMap table being 1-19, that should be 39-741 Ohms for the fuel gauge in the E65/E90 right, or am I missing something? Otherwise I can't get the full gauge range. I have ...

Thats right. The firmware does not yet support the new features. As I'm sure you are aware there are only a few of us working on this project and those that are have other commitments.

Understood and no problem:) but I couldn't find any info on the exact hardware to implement it myself. Any ...

DigiPots changed to a constant current driver that emulates a resistance range of approx 50 to 400 Ohms to ground. Inteded to drive analog fuel, temp gauges etc by emulating a resistance based sender.

So I just got the new v2 revision delivered. I was using the digipots on hardware rev1 for ...

Yes, It's taken a while because I wanted to get my car through inspection before end of last year.
But now I'm back to finishing the controller.
Hopefully it will we ready for purchase in a month or 2, I just need some time to test everything properly.

Nice project!
For my car I've left in the original coolant heater core and decided to use a plate heat condensor like this one with 60 plates:

It handles the pressure and ...

Hello everyone!

About 3 years ago I started the project of converting a BMW 3 series E90 to electric.
Progress can be followed here btw: https://www.instagram.com/wim.boone/

But anyway, along the way I decided to implement the Tesla model 3 heatpump as soon as it came out.
My approach was to make ...

Hi everyone,
I was just trying to harvest a batman chip from the high voltage controller. But I'm having a hard time getting it off without damaging it.
Does anyone have some tips on what equipment to use and what temperatures?
I tried using the hot air soldering station but even when the solder ...

Didn't realize this thread existed! Adding myself into this effort. I have a US long range pack with all penthouse components.

I've seen two different part numbers for this, haven't talked to any suppliers yet
