Prius Prime and the mg1/mg2 situation

Confirmed today on the 23 AWD that the power routing display shows NO charging current flowing back from the rear MGR to the battery. It does show flow from the battery to either left or right rear wheel when turning onto a road. Checked multiple times and there is no current depicted flowing back to the battery from the rear wheels under braking. It of course shows the reverse braking current flowing from the front MGRs. So, either they deliberately have omitted this from the display, or it's not happening. I tend to go with the latter. Just being used as motors as needed.

 

Have you tested a variety of speeds and braking conditions? I've tested city speeds using hard, medium, and soft braking, but I haven't tested highway speeds yet. I found no rear motor regen at lower speeds(<30mph/50kph).

 

Good ideas, will continue to test. I mainly checked low speeds.
