I was wondering if someone here understands the mechanics behind the brake regeneration system on the Tesla. I also have a hybrid ICE which uses brake regeneration as well. When I brake lightly, it shows me it is using brake regen to charge the battery (not using the brake pads at all). If I press on the brake harder, it simply regenerates the battery faster. If I press the brake pedal hard enough, the actual brake pads of the car kick in. This system seems very efficient and intelligent.
In speaking with reps about my MS, it seems it doesn't work that way: When you let off the gas, aggressive regeneration kicks in automatically. But if you press on the brake pedal(even a little bit), it doesn't increase regeneration but instead activates the actual brake pads.
So my questions are:
1. Do I have that correct with the differences between my hybrid car and MS?
2. If true, why would Tesla design it that way? My hybrid system makes much more sense: it uses less battery and regenerates more energy. It would work even better in the Tesla because you wouldn't need to "adjust" how aggressive you want regen to be. It would simply increase regen as you increasingly apply the brakes until it reaches the maximum and then would automatically transition to the brake pads.
Also, new MS drivers wouldn't have to "get used to" the aggressive regeneration...
