Do cars with dual chargers have stiffer or deeper regen?

    Just wondering if the on-board chargers affect driving dynamics at all?

    I've got dual chargers and I know they're both working on the wall charger (80A throughput from HPWC, and J1772 stations..).

    Just wondering if these chargers come into play on the regen side when slowing down, or if they're bypassed and recovered kinetic energy finds its way back to the battery along some other route? Maybe directly form the inverter to battery pack.

    Does everybody's regen scale go to 60kW at the deepest level? Or just those cars with dual chargers go that deep with single charger cars stopping at 40kW?

    Nope, regen doesn't pass through chargers.

    The onboard chargers are for AC charging (as opposed to the Tesla Superchargers which are DC). They have nothing to do with "driving dynamics" or regenerative braking as far as I know.

    Each motor is controlled by individual controller and should be able to push through 2x, but determined by the software

    Dual chargers not dual motors. I have one motor in my S, twin chargers.

    But you raise a good, similar, question about the possibility of dual motor cars having stronger regen. Intuitively, it would seem so, as the inverse of forward thrust could be captured better with two motors-come-generators working on it.

    Thanks for the clarification. I thought you are talking about 85D

    It seems that stronger regeneration might be possible through a P85D firmware update.
