I like your software approach. Are you aware of : https://github.com/collin80/GEVCU7 . Quite similar approach and the most mature SW architecture I now for EV conversions. There are more https://github.com/mumme74/CarTransporter with good approach for PID, https://github.com/jamiejones85/ESP32-Chade...

When will you all arrive in Augsburg? Is it better to arrive before 15:15 or after 16:00 to have some discussions with everybody?

I am wondering the same. Which one is coolant input ? WHich one is coolant output? Which orientiation does it have in the car?

I plan also to come arround. Do you come with some converted cars?

Nissan Leaf PDM missing

Looking forward to see your project. As I am also looking forward to convert a T5 , but fully electric. The range of options for what you want to do , even out of spec : - Mild hybrid with 15kw Bosch 48v alternator generator. Can really support in all coasting situations. Easy mechanical integration...

Any CAN log files, any DBC or even running code yet? Is there any chance, they a using the same messages as ID.3 ID.4 ?

Went through all the thread but didn't find anything about it: weher do you take of the brake preassure for regen by openinverter?

Hello,
I am currently designing a derivate of the outlander ECU , which I will publish soon. I want to consider also the ability to measure coolant temperature. Do you have an idea, what kind of temperature sensor, Tesla build in ther coolant sensors?

Sooner or later I also will need such a pack , maybe with 12 8s modules. I still need to determine size and weight .

However maybe we can team up, to bring the packs from UK to Germany. Feel free to PM me.

Best regards Felix

I know chances are quite small , but how can I still protect the motor from a loose cable potentially destroying the sdu ?

Does somebody know the cable size from the rapid splitter to the charger and to the front junction box / front sdu ? The cable to the rear LdU are according to Weber 50sqmm cables . From charge port to obc as well 50sqmm.

I am thinking to purchase the harness to use it fully in my project .

Like shown in the picture? What do you think of cutting the rs232 traces of and connecting the HVIL emergency stop except?

Which wiring diameter does the Tesla SDU Rear Unit have? I got some 50mm² cables with fitting connectors, but they they FJB Side on them.
I will add the information to the wiki, if somebody can confirm.

Interestingly I had the same issue and already started a topic on this: https://openinverter.org/forum/viewtopic.php?t=4143 . Therefore I am very interested in your outcome. My SDU Rear unit is leaking just around one drop per day into the inverter housing. When I bought it used it hat just some doz...

Is it on GitHub ? Very interesting for my project.

BMW i3 32kWH and 40kwh working with simpbms are maybe also worth a look.

Just do be clear, that I understood you correctly. Unbenannt3.PNG Unbenannt2.PNG Wouldn't be it better to have a poll down e.g. 2kohms mounted inside the inverter , so that I externaly just need to interrupt the line? Further more I am a bit worried, as it is the 5V supply line of the micor , then r...

A little bit further in my investigation:

I would say , I 3d print a ring eliminating the play . And I test it after some minutes of running, if it’s not leaking anymore.

Any opinions on this ?

This is how I did it. Will link it in the wiki .

After watching some SDU disassembly videos I am pretty sure , that this is not normal. It was just a few spoons of oil and only on the motor side of the inverter housing. The Inverter itself is fully dry. As my temperature sensor seems to be loose, that might be the reason. Did I get a SDU with defe...

Hello all, I was just measuring my motor as Damien did for the large Drive unit and recording a video to have all the documentation how to do it on the small drive unit. However, when I opened the inverter housing to my surprise, I found a little bit of oil at the bottom. I tink this is not how it’s...

What is happening, if I remove the 12V supply of the Open Inverter controll board when hitting the emergency switch? I am thinking of building up a system with a VCU that can switch between a charging mode -> VCU closes contactors no voltage to oi board and a drive mode -> 12 V to OI board. Addditon...

Hello all, I bought yesterday a project from somebody else who burned is battery and inverter. I will make a post about it soon in projects section. I opened the inverter today. Propably most dirtiest board you ever saw. I still gave it a try. Cleaned everything, 5V power supply looked blown so I un...

I am looking for the Tesla Model S small Drive unit inverter. Please make me an offer with a price indication.

Best regards,
