Can regen brakes keep a car stopped? I would think that the braking force diminishes as the rotor speed approaches zero so it wouldn’t keep you in place on a steep hill, but I’m not sure.
In my experience, it’s usually but not always enough for the hills in SF. But more importantly, regen can’t handle emergency braking (it would generate too much current and heat), and you can’t regen at all if the motor loses its path to the battery.
Good point, I guess the motor could be engaged just enough to hold the car still on a slope but there might be heat issues doing that for too long. Mechanical brake will do that easily so also needed for that reason.
