How Regenerative Braking Works
Regenerative braking converts kinetic energy back into electrical energy during deceleration. The electric motor acts as a generator, producing electricity that charges the battery. Typical systems recover 60-70% of the available kinetic energy. Efficiency depends on motor design, battery state of charge, and braking intensity. Maximum regen is achieved with gradual, predictable braking rather than hard stops.
