Great

Also surprised about the offset though.

And here are my parameters, Gen2 Leaf inverter, Em57 motor, control board with Mini Mainboard, so same as your setup I believe

I have one with BMS cell module but I guess you need more?

Judging from the modules I'm using it is 98% SOH

It runs on an STM32 but the code should be more or less hardware independent.
I didn't figure out the BMS that was Tomdb https://github.com/Tom-evnut/VW-bms/tree/master/VWBMSV2 and I shamelessly stole from him

Not sure where this post fits best as it is kind of a road trip, EV improvement and CCS mix. So, I went to Hamburg to meet Mathieu who has done various conversions like the Mustang and Toyota Land Cruiser. Plan was to get CCS up to speed on the latter and fix a few things on Touran. I wanted to make...

The behaviour is expected, both motor and resolver have 4 polepairs so one physical turn is 4 electrical turns. I'm also puzzled that pinswap=6 stops the motor because the pins are swapped on the mini mainboard (https://openinverter.org/forum/viewtopic.php?t=2760) Can you post the output of http://1...

Oh that is indeed possible with that host of parameters. Will add the size change, maybe the output (quite long)

Have you only programmed the file system but not the firmware? (pio run - - target upload)

Sounds much like it. Maybe air or flow rate too low?
Plot tmphs and tmpm while driving
Compare to tmpmmax and tmphsmax

Moved to Toyota section

Like said, don't mess with any parameters, just accept that the label reverse means forward and vice versa.

It runs fine apart from spinning in the opposite direction, right?

Do not alter syncofs.

Just reverse your gear selection either per dirmode parameter or physically and be happy. Reverse=Forward

Also upgrade to the latest firmware for safe operation: https://github.com/jsphuebner/stm32-sine/releases (stm32_foc.bin)

The 4 cell modules are now sold off : https://openinverter.org/shop/index.php ... duct_id=80

For years I have had boards blocking my storage space that I don't have the time or ability to really sell as a product. Mostly looking to get rid of them and maybe recoup some material cost. These are now available in the "meta product" on the shop: https://openinverter.org/shop/index.php...

Can you post your code that generates the CAN message and a dump of a few messages?

Dodgy connection or bad 5V reg? Thou shall measure voltages. do 12V arrive at the regulator and do 5V come out? Do 3v3 come from the 1117 3v3 reg?

Hopefully someone out there can help me out with details on how to use these BMS? I'm not sure whether these have been reverse engineered. I'm assuming they are "dumb" modules that report to some main module and executes its balancing commands. You can find code for calculating various hi...

Finally got around to re-assigning the connector pins and made the flash SPI easier to access. Moved some components around to reflect the new placement also. I'm calling it 4.5b as it is electrically identical to 4.5. Didn't want to burn up another version resistor. Does that make sense? grafik.png...

Anyone? Bueller?
Take the BOM of Zombieverter for example and add its connectors.

I should repeat this here: EVERYONE whos got a forum login can use it for the wiki as well. You don't need special permissions

Hi, is this open source?

Great, congratulations
Is there any kind of inspection or just paperwork?

Good job

One things I noticed, the vacuum pump comes on often and could use some turn-off hysteresis. How is it controlled?

Yes, its a remix of Toms code and tailored for 8 modules:

https://github.com/jsphuebner/stm32-car ... mebbms.cpp

Should be sufficient for grasping the principle and proven to work

Welcome

An arduino can hack it. You'd not use 0-5V but rather PWM as that is more common.

When creating new threads use a descriptive title. I've changed it for you

But with one motor per wheel
