Does anybody have any information about the battery management which will be used in Model S ?
Simple logic would indicate that it would be practically identical to that used in the roadster, which may have been tweaked since its inception. I can't imagine any reason for it to differ, unless
the new cells that Panasonic will provide for the 300 mile
packs allow for some changes.
I would guess it would be an next gen from existing Roadster. They need to enhance BMS to support 480 Volts/60amps fast charging. Also, new high capacity cells for 300 miles pack.
Wishful thinking for the above upgrades. Best to cross fingers in pray the tesla does so to be ahead of the competitive market that is about to explode.
