    Ebike Using ABB VFD

    Would it be practical to do something like this. Build 4 x 72V packs (20S2P) and then series them up. Pack Config Image Link https://drive.google.com/file/d/1OAa-kmUmuRHuNi7Azq8MIOasZLFWxr_Q/view?usp=sharing I could have the pi zero monitor the BMS healthy status and if any pack goes out of...

    Yeah the cell balancing is one issue and the charging is another. I was wondering if it could have 2 charging ports that essentially charges to halves of the pack separately to make it easier. The BMS I'm not sure about yet but would love to be able to do cell balancing in a cost effective way...

    I think it's roughly 4A load through the battery. 3000ma LG brown 18650's maybe. Probably run a pack in parallel as well I guess to get a bit more run time. Plus should not be pulling FLA all the time. Guess some R&D is needed to confirm that.

    Ebike Using ABB VFD

    Hi, thanks for the feedback. Yeah the first motivation is that I have access to these VFD's and induction motors essentially for free. Also I use them in my line of work so it's value adding to work with them in this less common application. I think it has potential. I was thinking maybe the 80...

    Ebike Using ABB VFD

    Hi, New post here. Just saw something today that got me thinking whether this is practical or not. Using an ABB ACS355 variable speed drive to run a 0.75kW 3 phase motor to run an ebike. This drive normally taking single phase in and giving 3 phase out can be powered with DC directly to the DC...
