BMW, as befits a company focused on electric vehicles, is keeping battery and drivetrain production process in-house.

Here are two unique videos on how li-ion cells are assembled into modules and then into i3 battery packs.

The next two videos showcase the i3’s single-speed transmission and an automated process of hybrid synchronous motor assembly.

    Nice high quality videos.. But it would have been better had they trimmed all of these down into a single 5 minute video and added some narration explaining to the viewer what is going on.

      LOL, I was just going to say to opposite. I enjoyed the longer raw video w/no narration.
      Interesting they used ABB robots instead of Kuka (in a German plant).
      Oh and where was the beer 🙂

        Looks like lots of Siemens controls (German).

        Yes, surprised to see that also. Especially since Tesla is using KUKA too. I’m familiar with their main facility in Augaburg, went to school nearby.

    By golly I do believe this battery is cooled from the bottom just like the spark EV battery. If you look at the second video at 28 seconds you can see a tray with cooling tubes that all the modules sit on.

    This is similar to the way the spark battery is cooled as explained in an article I wrote here:

    1. George B says:

      Yes, that appears to be the case. Thanks for the link!

    Also interesting is that the gearbox is a simple helical/spur gear set as opposed to both the spark and Volt transmissions which have planetary gear reduction.

    Spark coaxial gearset looks superior to me as explained in this article:

    Well you gotta give credit to the Germans . . . they are working hard to keep the jobs in their own country.

  5. I’m not sure where you are getting your information, but good topic.
    I needs to spend some time learning much more or understanding more.

    Thanks for wonderful info I was looking for this info for my mission.
