Help: supplier for electrical machine electronics in i3

Mon Feb 15, 2016 7:06 am

I'm the fan of BMW i3, and when I'm reading about i3 specification, a quesiton pops up in my head:
Who is the supplier for electrical machine electronics(EME) in i3? or this key high voltage component is produced by BMW himself?
Appreciate a lot for your answer here!

Thanks janner. You are right that, Delphi provides the EDME(electrical digital machine electronics) for i3, which may call it the vehicle controller, it coordinates with EME (electrical machine electronics), transmission, braking system... for the whole vehicle level control.

and EME is a very critical component in this e-powertrain system. I'm wondering who is the supplier? BOSCH, Conti, or someone else, or BMW home-made?

Appreciate a lot for your help!

The electrical machine electronics of the i3 (I01) is developed and supplied by the relevant departments of BMW AG. The production is carried out in a division of the plant in Dingolfing.

Seems BMW have taken the view that IPR of the motor and drive (EME) is key to their future success. I think they're right.

Pleasure.

Would be great to know what electronics are in the EME. I've assumed that the EME is IGBT based but I've not managed to find anything that says so.

Infineon provide 75 semiconductors ensure a highly efficient electric drive in the BMW i3, e.g. Microcontroller AUDO Future, IGBT Power Module HybridPACKTM 2, EiceDRIVERTM Products, CoolMOSTM High voltage MOSFETs.

The EME is made by BMW. I have had the rare chance to successfully repair one instead of paying $5000+ labor.

Wow, I'm impressed! How did you diagnose it and find the root cause?
