The key principle behind regenerative braking is the conversion of kinetic energy into electrical energy. This is achieved through the use of an electric motor, which acts as a generator during the braking process. As the vehicle slows down, the electric motor is driven by the rotating wheels, generating an electrical current that can be used ...

Regenerative braking is an energy recovery mechanism that slows down a moving vehicle or object by converting its kinetic energy or potential energy into a form that can be either used immediately or stored until needed. Typically, regenerative brakes work by driving an electric motor in reverse to recapture energy that would otherwise be lost as heat during braking, effective…

Embedded energy storage sources such as SCs or batteries are used to perform recovery braking. They are a more viable alternative to recover energy during braking. This option is similar to the one used in an application with a high-start/stop frequency such as elevators driven by synchronous machines [ 36, 37 ].
