Mmm, what I'm ultimately talking about is converting kinetic energy into electrical energy and storing it in the battery pack. An RC car in motion is in a state of stored kinetic energy, the magnitude of which is proportional to its momentum, and the source of which ultimately came from the electrical energy that the system took from the battery to accelerate the car to whatever velocity. If the object's motion is stopped, its kinetic energy is transferred elsewhere. The key is to transfer as much of that energy back into the battery pack.
But the problem as I see it is as I outlined in
post #14. The voltage generated by the motor needs to be stepped up somehow in order to charge the battery...
