    I recently stumbled over this:

    Infineon supplying power chips to Tesla

    What does this mean? Infineon was recently working on new "active charge balancing" electronis to get the max. charge into each cell of interconnected li-ion batteries (like in the Roadster & Model S).

    There are some interesting papers aroudn that subject:
    Large Li-ion battery packs: Active balancing improves many parameters - Part 1

    Building Battery Arrays with Lithium-Ion Cells

    There's also a vid where you can see the guys from Infineon advertising the active balancing sollution (sorry it's in German....battery part @ 03:00):

    I wonder if the current Roadster Battery Managemt incorporates an active balancing process - and if it's already the "new" process based on DC/DC converters...

    Doesn't mean anything. They supply many different types of power components to many companies.
