Does the Generator Participate in REGEN Braking

[Xzlon]

Some time back I postulated that the clutching arrangement would allow the generator to be used as the primary regen path. Now that GM has stated that regen could be as much a 60KW the generator would not have the capacity to take all the regen energy. I question now that the generator would be used at all for regen. Assuming the generator is locked to the ring gear and stalled at zero rpm in full EV operation(shown as Transition in the truth table for the clutches) there would be a question of a noticeable bump due to it being clutched in and accelerated up to speed to act as the regen generator. That makes a case for using only M1 for regen since it is already rotating. Just need to phase M1 control from motor to generator. This would make for a more simple control logic by keeping the generator out of the equation. Someone stated that the six orange cables between the power electronics controller and the drive case was one set of 3 for motive power and one set for regen power out. True? I don't recall ever seeing the cables for the generator being shown or described in any illustration. Is it 3 phase requiring six leads also? Would it become invoved at all in regen?

Simple answer. Yes it is used but only under certain conditions when (as you allude) the correct clutch configuration exists.

Someone stated that the six orange cables between the power electronics controller and the drive case was one set of 3 for motive power and one set for regen power out. True?

However this asumptionis totally false. Quite simply 3 cables is needed for each motor generator unit. All that differs between motoring and generatng modes for either is the direction and path of current flow.
