Thanks Embassy.* That's a useful insight.* Regen braking is set to mimic conventional engine braking, but if it is under software control then it could be varied.* One possible scenario would be the car leaving a house on a full charge and having to go straight down a steep hill.* Unlike brushless motors, induction motors do not have to act as generators.* (It's one of those phase/timing things)* * Regen braking would be off so it would just feel like freewheeling with the clutch in.* Mechanical braking would have to be used.
Does this put us back to a Tesla battery pack containing mixed battery types?* Astonishing achievement if true.
