Hi All,

Has anyone tried to control the electric aircon pump from a BMW i3 or PHEV.

it can operate between 200v and 400v and runs on a lin bus.

Amazing Work can wait to get the motor spinning on the inverter

Hi All, Just wondering if anyone has looked into the High Voltage DC/DC converter on an ID3? found one on ebay but was look online and 400euros from oemvwshop https://www.ebay.co.uk/itm/144276448778?hash=item21978be60a:g:1zoAAOSwaY1hg-VX https://www.oemvwshop.com/1ea907190d-voltage-transformer-p2899...

Awesome work order placed

Hi all been a while, how goes the progress on the new control board ?

I cant speak fully for the BMW side as i work more on VW/Audi (below an example of audi hybrid 8sepeed gearbox) hybrid gearbox.jpg when it comes to a hybrid manufactures have gone many different methods of control. some making the engine ecu decide when the transition happens some leaving the motor ...

Hi, Making a hybrid is one hell of an annoying challenge. you could setup the engine as an independent part and the motor control as an independent part but will have to make a module that would operate as a transition between the two. that module would also need to send control signals to the gearb...

hi its 950 x 600 x 200mm with the bump on the top going upto 250mm

For general linbus testing i am using a microchip lin bus analyser link below. the generic software is abit basic and could really work with making something custom but it displays addresses and data. it also allows to transmit. which is helpfull for quick testing https://uk.rs-online.com/web/p/comm...

i have the complete inverter, can give it a test fit if heikki cant im in the UK if that's any easier for you.

Hope this helps.

there's also the starter generators from the kia niro and Hyundai iconic its a permeant magnet motor with 14kw max output. this has a simple 3phase output so you have to make your own controller for it. but it has a built in resolver. the same setup is on the BMW i8 WhatsApp Image 2021-03-30 at 22.2...

Thanks this is what i have found scanning an a3 etron climate but as it wasnt connected to car 64 data in 40 00 28 68 classic ac pressure sensor a8 data in 0B 02 1d 02 a2 31 2b 02 enhansed air quality sensor e7 data out FF FF 94 6c 70 00 5a ff enhansed No responces 50 data in 2E 97 06 3d 02 44 80 31...

never mind got my binary the wrong way round send 55 05 and it works

Huge Thanks you have been a massive help

Hi thanks im trying this now in the garage cant seem to get my compressor to work im sending the message on 0x20 55 A0 00 00 00 00 inital responce from pump is 0x61 00 70 08 00 00 00 00 followed by a repeated 0x61 00 FB E8 FF FF FF FF voltage to the compressor is 336V i have not bridged the pilot li...

I managed to get my VW / Audi air conditioning compressor running today. It works with a nominal 352V and is controlled with a LIN bus. So far I haven't read much about the LIN bus here. But it's easier than CAN. There is a master (my controller) that sends headers, followed by 2 to 8 bytes of data...

Hi this is the pinout for the battery external connecter as near as i can figure.

Hi All, Heres some pics of the Golf MK7 GTE hybrid battery its 8.7kw watercooled. the bms communates to the battery modules thru canbus. if any one has a golf GTE or Audi etron near London who wouldn't mind letting me plug my diagnostic into to get the canbus control messages would be mega helpful. ...

Hi Great work :) yep audi also have a 12v version which i have of the starter generator from the SQ7 but that operates on the lin bus below are some of the spec about the 48v version. now if only someone had the lin bus decode or has a hybrid golf in london i could plug my scanner into. Startergen1....

Amazing work let us know when one is ready for purchase

also can you add a VW section into hardware i have a VW GTE battery pack that i can show dissembled

Hi All, sorry slow progress as back to work. been looking online and wonder is this buck booster would be a nice enough circuit for the 32v supply. https://www.ebay.co.uk/itm/DC-DC-4A-Boost-Converter-3V-32V-12V-to-5V-35V-24V-Step-Up-Power-Supply-Module/252676342631?hash=item3ad4af0367:g:prIAAOSwJ7RY...

Great work Johu :D Yes that is the correct header mine arrived today and fits beautifully. Infineon made an evaluation module for Hybrid pack. i have been comparing the schematics from there datasheet to this module. there are a few differences but helped narrow things down. links below https://www....

Great work, nice to see a few more pins have been found i was suspecting a digital pins used, as i been trying to follow the hybrid pack eval board design. which they seemed to have barrowed there ideas from i haven't tested to much lately as my garage has been below freezing and awaiting for the co...

Got my inverter today and started the teardown :D got to the IGBT board and started probing the lines, figured out a few more pins. the IGBT has 3 temp sensors but couldnt seem to find where that signal leads to. looking at the connector on the board looks like https://www.mouser.co.uk/ProductDetail...

Theres this one here for about 62 euros with obvious damage but maybe a cheap place to start https://www.xdalys.lt/en/bmw-i3-inverter-converter-loading-6144-8689350_others Thanks unfortunately i think this is the charging unit not the inverter. Bmw went about the design of the i3 high voltage syste...
