Regenerative braking is a process used in mobile engines to recover part of the kinetic energy and recharge their batteries.
The principle is to transform the vehicle's electric engine into a generator during braking phases. The rotation of the wheels drives this generator and produces electricity, which is stored in the batteries.
This type of braking is used in locomotives, some elevators and electric or hybrid vehicles.
