Regenerative braking slows the vehicle by having the traction motor run as a generator. When you slow down, the motor is driven by the wheels and is forced to generate electricity. That generation creates an electrical load on the motor, producing resistance that opposes the wheels’ rotation and adds braking torque. The electrical energy is then sent back to the battery for storage via the vehicle’s power electronics. This is different from ordinary friction braking, which uses hydraulic pressure to squeeze pads against rotors. The battery stores the recovered energy, and a hydraulic pump or servo motor isn’t what provides the regenerative braking resistance.
