Regenerative braking turns kinetic energy that used to heat brake rotors into electrons heading back into the battery, and the marketing math is much friendlier than the physics math. We walk what the inverter and motor actually do during regen, blended-brake coordination, one-pedal driving honestly, why the recovered energy is not a free range bonus, and where regen lives in real-world mixed driving.
