Hey electron heads!

Today I did some minor work on the conversion project, a bit of motor alignment and measurements for some laser cut brackets.

I also test fitted the Outlander inverter and after trying serveral locations this seemed to be the most logical one, other positions were to close to ...

Hi Sander,

The cooling plates are 2mm and the center is 4mm. If I would do this again I'll probably go a bit thicker on the outer plates. But the 3 plates screwed and glued together it's reasonably stiff.

The covers were made out of 1mm steel folded and TIG welded. I only have a TIG welder so ...

No its not on me to release. I can provide you access to the "Testing branch" when we get to it. You started to document your wiring be good to work on getting something drawn up. This I would say is an ideal "starting" project with readily available parts.


Right, I see! When I'm up to it i'll ...

Thanks for the heads-up Tom! Enough work to do so that subject can wait!

Do you have an indication on the release date for that code?

Thanks!

Did not know that the battery boxes take so much time to make.

This is the front box holding 8 modules. Did not take into account that the box needs to hold two ...

Hey all,

So, after spending some time trying to get SimpBMS running on a ESP32 I decided to put that aside and start testing all my components chained together to see if I was able to get a "first motor spin". Previously I tested all components separately using Zombieverter v2.17, that all worked ...

Hey,

I've tested everything again, after connecting the S-BOX to CAN 1 instead of CAN 2 and connecting a 30V power supply, UDCSW did show a positive value. At that point it was possible to close the contactors, UDC and UDC2 both show comparable values.

So that all worked out nicely. I have to ...

Hi Tom and Mitchy,

Ok, great! Thanks for your ultra fast response

I'll connect some power to the S-BOX and proceed testing. I'll report my findings here.

Cheers

Hey all,

Currently combining all my parts to test a first motor spin. Previously I tested communication between the Zombie and my Outlander motor, inverter and charger, this all went well for as far as i could test them. After that I calibrated a throttle pedal which i picked up. When testing the ...

Hey all,

Another update: so, after checking everything from the ground up I found that I failed installing the right Async TCP library in Arduino IDE. After installing the right one I updated the board manager (ESP32 3.1.1) to the most up to date version and compiled and uploaded everything. After ...

Hey all,

A small update on my last post:

I've tried out several combinations of board manager versions and library versions and I was able to compile and upload SimpBMS to my ESP32 board. Using library ACAN_ESP32 version 1.1.2 in combination with board manager esp32 version 2.0.11 (all other ...

Hey all,

I decided to buy an ESP32 dev board and try out SimpBMS software for my BMW battery modules. I used this earlier ported ESP32 code: https://github.com/bookofthefuture/BMWPhevBMS-ESP32 . At this moment the ESP Arduino core is at version 3.1.1. I tried to compile the code but ran into some ...

Is it ok to mount these modules on their side? Not all HV modules can be orientated this way


I'm only copying others ideas and experiences :D

Arturk has done a really nice Jag conversion: https://www.youtube.com/watch?v=8RAvX9RylRU&t=399s . Around 5:30 min in the video. This build uses ...

Hey,

Today I've doing some measurements on the BMW battery modules and how I could fit the in the buggy. Initially I was thinking about a split battery pack, so 4 modules in the front and 2 in the back for space an weight distribution. But it comes with additional complexity and costs so I skipped ...

Hi Tom,

Thanks again, that sounds what i need! Great!

Road legal...yeah that is a bit of a race against the clock. Previously you could convert your car and have it checked by the authorities, when you get their blessing the conversion is the approved and legal. But...some rules might change ...

This really depends on what you feel comfortable with. I developed the SimpBMS which is fully opensource https://github.com/Tom-evnut/BMWPhevBMS
Unfortunately due to the stopping of making of the Teensy 3.2 chips i have had to fully redesign it and improve it into a more commercial product which ...

Have you watched Greg's video's yet? Proper deep dive into the packs: https://www.youtube.com/playlist?list=PLh-aHjjWGgLUyHrJpTbM2bO-AReCe1j6a


Hi Marcexec, thank you for your message! Yes I did check Greg's vids, very informative! In fact, his vids gave me enough confidence that I would be able ...

Hey all,

Still working on the project in the spare time I have :D

Initially I mounted the Outlander rear motor to the tube frame of the buggy. But on second thought I came to another idea to fabricate a subframe and some brackets and mount the motor on that using a some of industrial vibration ...

Hi all,

Yesterday I safely opened up the BMW SP41 pack, seeing the inside of the pack in real life is such a joy! I've never opened up a HV pack before, but i can really enjoy how well such a pack is designed!

After disconnecting the HV cables I measured the voltage of all modules, they were all ...

Good luck with the disassembly.

Hey Manny, thanks! Aangepast.

Look what arrived on my doorstep today!

Time for some next steps in my journey, I'm super excited!

Hi Iceman,

I think you should set up a new thread to explain your issues. Likely the knowledgeable people here can help you out.

Off topic: Unfortunately, at this point I'm not able to help you out as you are like miles ahead on my progress . Tomorrow I receive my BMW 12 kW pack, first I will ...

Excellent, gratz on your purchase!

For my comparison, what build year and car milage has such a pack?

Thanks!

BR Sander

Hi Sjanders,

Like you I have recently received my Zombie, with the same 4 IC’s that need to be soldered onto the board (IC12 & Ic’s27-29). I have been looking for confirmation of which parts go where, and your Query, and Damien’s reply have cleared that up - so many thanks to both of you. I also ...

Hey all,

I've searching for a BMW 530e battery pack. I have found various suppliers with a rather large price range. The found range was from 495 to 4200 euro for a 12 kW pack. Comparing the build year an car milage there was not a huge variation between them (45000-58000 km), except for one ...
