This is a very detailed look at how regenerative braking works:
Hybrid and EV Regenerative Braking Systems
He has all of the components on a test bench opened up, he goes into great detail and demonstrates the workings very clearly.
0:00 Introduction
Components involved at 0:50
Motor Rotor at 1:25
Motor Stator at 1:56
Stator connections at 2:15
Electromagnetic induction example #1 at 3:40
Electromagnetic induction example #2 at 5:19
PicoScope oscilloscope 3-phase stator output measurement at 6:20
PicoScope oscilloscope 3-phase stator output waveform interpretation at 8:50
MUST SEE! Electric motor loading (braking) example at 12:15
MUST SEE! Letting the smoke out at 14:10
Regenerative braking electrical/mechanical summary at 14:40
Transmission shifter "B" Braking position at 17:30
Negative torque at 18:28
MUST SEE! MG1 driving MG2 with 3-phase induced voltages at 19:39
The reverse motor rotation at 22:00
Low voltage efficiencies at 22:45
Video summary at 23:49
