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...

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