A word on active balancing li-ion batts

[suxxer]

I recently stumbled over this:

Infineon supplying power chips to Tesla

Infineon power ICs are used in the Tesla Roadster and are being tested for use in the Model-S

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.
